DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an information recording and reproducing apparatus 6 according to a first embodiment for recording and reproducing information provided by an information providing and collecting apparatus which is a transmitting apparatus for realizing the transmitting method of the present invention.
It shows the appearance of 00A.

The information receiving / recording / reproducing apparatus 60 shown in FIG.
0A has a display section 302 and a reproduction selection button 303 similar to the information recording / reproducing apparatus 300A of FIG. 11, but the information receiving / recording / reproducing apparatus 600A is replaced with the coupling terminal 301 of FIG. For example, information is provided from the outside (information providing and collecting device) by an infrared receiver 601 including a photodiode for receiving infrared light and the like. Note that, in the example of FIG. 1, the connection terminal 305 for connection to the information providing / collecting device is omitted, but the connection terminal 305 can, of course, be provided.

FIG. 2 shows, as a second embodiment, the functions of the information receiving / recording / reproducing apparatus 600A of FIG. 1 as in the second conventional example. 2 and 3 show examples in which they are physically separated.

Therefore, in the configuration of FIG. 2, the information receiving / reproducing apparatus 700 is provided with a display section 302 and a reproduction selection button 303 similar to FIG. 1, and further, an infrared receiver 601 is provided. Etc. can also be attached. Further, the information recording device 800 and the information receiving / reproducing device 700 are provided with coupling terminals for transmitting / receiving information between the information recording device 800 and the information receiving / reproducing device 700. FIG. 2 shows only a connection terminal (information reception / reproduction device connection terminal) 801 on the information recording device 800 side for connecting the information reception / reproduction device 700 and the information recording device 800. further,
In the example of FIG. 2 as well, the information received by the information receiving / reproducing device 700 is transmitted to the information recording device 800 by inserting the information recording device 800 into the insertion / ejection port 701 of the information receiving / reproducing device 700, or The information recorded in the information recording device 800 can be transmitted to the information receiving and reproducing device 700.

As in the second embodiment described above, the information recording device and the information receiving / reproducing device do not necessarily have to be integrated, and information transmission between these devices is performed as described above. Not only through the insertion / ejection port, but also by wire or wireless transmission.

According to the transmission method of the present invention, when information is transmitted from the information providing / collecting device, the information providing / collecting device is transmitted at a bit rate higher than the information reproducing speed of the information receiving / recording / reproducing device or the information receiving / reproducing device. (In particular, a specific part of the information is frequently and repeatedly transmitted), and the information receiving / recording / reproducing apparatus or the information recording apparatus which receives the information from the information providing / collecting apparatus has a higher speed than the information reproducing speed. Also, by recording information transmitted at a high bit rate on a recording medium at a speed faster than the same information reproduction speed, many users of these information receiving / recording / reproducing apparatuses and the like can easily and quickly (wait). Without providing information).

Therefore, when information is reproduced by an information receiving / recording / reproducing apparatus or the like, the information recorded on the recording medium is reproduced in accordance with an instruction from a viewer, so that a large number of users can easily and quickly reproduce the information. Can be provided with a time signal. Further, in the present invention, as described above, by providing information at a bit rate higher than the information reproduction speed and recording the information on a recording medium, for example, a place where the user can easily receive from a place where reception is easy to be performed is deteriorated. (The user has moved away from a place where reception is easy), the user can freely reproduce the information received and recorded in a place where the reception condition is good.

The configuration and operation for providing information at a bit rate higher than the information reproduction speed and recording on a recording medium as described above will be described below. Hereinafter, for ease of explanation, an example in which the information recording device and the information receiving and reproducing device are integrated as in the first embodiment will be described as an example. It goes without saying that the present invention can be applied to the configuration of the second embodiment.

First, an example of a use situation when the configuration of the embodiment of the present invention is actually used will be described with reference to FIG. FIG. 3 shows an example in which the viewers H move on the bus 900 as an example of the case where the viewers H move.

That is, in the example shown in FIG. 3, an antenna 901 for receiving a broadcast wave is installed on, for example, the roof of the bus 900, and a signal received by the antenna 901 is retransmitted inside the bus 900. Is installed on the ceiling. This information transmitting device 9
02 is provided with an infrared transmitter 903 composed of, for example, an infrared light emitting diode or the like. The infrared transmitter 903 can retransmit a signal received via the antenna 901. Also, each viewer H on the bus 900 has an information receiving / recording / reproducing apparatus 600A including an infrared receiver 601 as in the first embodiment, for example. Information can be provided by receiving a signal (retransmitted signal) transmitted from the infrared transmitter 903 of the information transmitter 902 by the infrared receiver 601 of the recording / reproducing apparatus 600A. That is, the information receiving / recording / reproducing device 600A possessed by each viewer H records the retransmitted information based on the instruction of each viewer, and records the recorded information simultaneously with or after the recording. Information can be reproduced.

Here, the bit rate of the information transmission from the information transmitting device 902 is set higher than the bit rate at the time of reproduction (the bit rate at the time of reproducing the information once recorded at the regular speed) as described above. The recording is also performed at a high speed. Therefore, each viewer H does not need to stay within the transmission range of the information transmitting device 902 until all the reproduction is completed. In particular, if information such as an audio signal is compressed in advance, the information transfer time can be shortened even at the same transfer bit rate.
It is possible to effectively shorten the time that the user must stay in the transmission range.

Next, FIG. 4 shows a specific example (information transmitting device 1) of the configuration of the information transmitting device 902 and the infrared transmitter 903 as an example of the information providing and collecting device.

In FIG. 4, a reception signal is supplied to a terminal 101 of the information transmitting apparatus 1 via, for example, an antenna 901 shown in FIG. The received signal is transmitted to the receiving circuit 10
Sent to 2. The receiving circuit 102 is connected to the antenna 9
If the received signal via 01 is an analog signal, it is converted into digital received information. The receiving circuit 1
The information output from 02 is temporarily recorded on a recording medium 104 as a storage unit whose recording and reproduction is controlled by the control circuit 103. After that, the information recorded on the recording medium 104 is repeatedly read out in the order controlled by the control circuit 103 and sent to the data separation unit 106. The data separation unit 106 converts the information supplied from the control circuit 103 into
After the data is separated into outline data from which the outline of the entire data can be grasped and complementary data that can be restored to the original data by synthesizing the outline data, the outline data and the complementary data are sent to the transmission unit 105. The transmission unit 105 is the infrared transmitter 9
03, and generates a drive signal from data obtained by time-divisionally multiplexing the outline data and the complementary data supplied from the data separation unit 106, and drives the infrared transmitter 903 with this drive signal. As a result, the infrared transmitter based on the information read from the recording medium 104 and the infrared signal based on the complementary data are transmitted from the infrared transmitter 903 of the transmitting unit 105.

Note that the content of the recording medium 104 can be appropriately changed, that is, rewritten, according to the information received through the receiving circuit 102.

Next, the configuration of one specific example of the information receiving / recording / reproducing device 600A (the information receiving / recording / reproducing device 2) of each viewer H will be described with reference to FIG.

In FIG. 5, a receiving section 122 includes the infrared receiver 601 and receives a transmission signal by infrared from the infrared transmitter 903 of the information transmitting device 902 (1) by the infrared receiver 601. In the receiving circuit 122, since the signal received and output by the infrared receiver 601 is an analog signal, the analog signal is converted into digital information, and the obtained outline data and complementary data are sent to the data synthesizing unit 124.

Since the data supplied from the receiving unit 122 is the outline data and the complementary data multiplexed in a time division manner, the data synthesizing unit 124 extracts only necessary data from these data. After that, the data synthesizing unit 124
Restores the original information by synthesizing the extracted outline data and complementary data, and sends the restored information to the control circuit 125. The information from the data synthesizing unit 124 is temporarily recorded on a recording medium 126 whose recording and reproduction is controlled by a control circuit 125 as recording and reproduction control means.

The control circuit 125 has a display unit 30
2 and the playback selection button 303 are also connected, and the control circuit 125
The viewer performs a display on the content of the reproducible information recorded in the display unit 302, and the viewer operates the reproduction selection button 303 based on the content displayed on the display unit 302 to give an instruction for reproduction or the like. The control circuit 125 performs a control of reproducing the instructed information from the recording medium 126 when a reproduction instruction is issued by the reproduction selection button 303 from the viewer.

Here, recording and reproduction on the recording medium 126 by the control circuit 125 are performed in a time-division manner, so that recording and reproduction are apparently performed simultaneously. Note that such time-division processing uses a semiconductor memory as the recording medium 126, and records (writes), for example, an even cycle of access to the semiconductor memory.
In addition, it can be easily realized by allocating odd cycles to reproduction (reading).

The information read from the recording medium 126 is distributed to the display unit 302 or the reproduction circuit 128 by the control circuit 125. That is, the control circuit 125
When the information from the recording medium 126 is video information, the video information is sent to the display unit 302 for display, and when the information is audio information, the video information is sent to the reproduction circuit 128. After converting the audio information into a time-series sample signal, the reproduction circuit 128 further converts the time-series sample signal into an analog audio waveform signal to be sent to sound emitting means such as the earphone 304. This analog audio waveform signal is sent to the sound emitting means via the terminal 129. When an analog video signal is also output to the outside in addition to the analog audio waveform signal, the video information is converted into a time-series sample video signal by the reproduction circuit 128,
Further, the time series sample video signal is converted into an analog video signal. In this case, the terminal 129 includes an audio output terminal and a video output terminal. The video signal is sent from the video output terminal to an external display device.

Next, an example of processing from transmission of information by the information transmitting device 1 to reproduction by the information receiving / recording / reproducing device 2 according to the embodiment of the present invention will be described with reference to FIG.

FIG. 6A shows a state of repeated transmission of all information to be transmitted (repeated transmission of all information having the same content) from the information transmitting apparatus 1, and FIG. 6B shows information reception. Receiving the transmitted information by the recording / reproducing device 2,
The timing at which data is written to the recording medium 126 is shown. That is, as shown in FIG. 6 (a), all information to be transmitted is the reproduction time T1 of all the information shown in FIG. 6 (c).
It is repeatedly transmitted from the information transmitting device 1 in a shorter time P1. Also, all information transmitted from the information transmitting device 1 is received by the information receiving / recording / reproducing device 2 and is shown in FIG.
Are written to the recording medium 126 at the timing shown in FIG.

That is, for example, at time t1 shown in FIG. 6B, when the viewer operates the reproduction selection button 303 of the information receiving / recording / reproducing apparatus 2 to reproduce the information, and instructs the reproduction, the time t1 The recording of all information received from time t3 to time t3 described below is started on the recording medium 126. Next, at time t2, the head of all information is recorded on the recording medium 126. As described above, recording and reproduction of information on the recording medium 126 are performed in a time-division manner, so that at the time t2, while recording the head portion of all information on the recording medium 126, Playback can be started from the beginning of the. Therefore, the viewer can obtain information from the head of all the information. Note that the detection of the reproduction start point (t2) of the recorded information can be easily realized by including a synchronization signal indicating the head of the information in the transmission information (all of the information repeatedly transmitted). it can. Thereafter, the transfer of the information to the information receiving / recording / reproducing apparatus ends at time t3, so that the viewer may go out of the reception range at this time t3 and get off the bus, for example. It is possible to play and enjoy.

The time point at which writing to the recording medium 126 of the information receiving / recording / reproducing apparatus 2 is started may be time point t2, and the time point at which the writing is completed may be time point t4. However, writing at time point t1 ends at time point t3. Therefore, the end point of writing can be expedited, which is convenient.

The information transmitting device 1 separates the information to be transmitted into summary data and complementary data, and transmits the summary data and the complementary data in this order. Recording medium 1 for summary data
In order to complete the writing to 26,
Even if the user goes out of the receiving range in step 5 and gets off the bus, for example, the user can obtain an overview of all information by reproducing the overview data. Therefore, the end point of the writing to the recording medium 126 of the information receiving / recording / reproducing apparatus 2 ends at the time point t3.
Even if the time is advanced from time t5 to time t5, the recorded information is established as summary data, so that the end time of the writing can be further advanced.

For example, all information is composed of audio signals for one music, and the data separating unit 10 of the information transmitting apparatus 1
In 6, when the audio signal is separated into a low frequency band component and a high frequency band component, the information transmitting device 1 transmits, for example, the low frequency band component as summary data and the high frequency band component as supplementary data. Therefore, the information receiving / recording / reproducing apparatus 2 receives the summary data and the supplementary data from the time point t1 to the time point t3, and combines them into one data band in the data combining unit 124, thereby obtaining the original 1 data. The audio signal for the music can be restored. Further, as described above, although the information transmission device 1 starts receiving and recording the outline data (for example, low frequency band component) of the audio signal at time t1,
Even if the viewer cannot stay within the reception range until the time point t3, if the viewer stays within the reception range until the time point t5, all the summary data (for example, low frequency band components) can be recorded. Although it is inferior to the original audio signal, it is possible to reproduce an audio signal for one music. The sound quality of the audio signal whose reproduction is started at the time point t2 is not as good as the original audio signal. However, in the reproduction after the time point t5, the original signal is reproduced by using the received and recorded complementary data. It is possible to reproduce with the audio quality of the audio signal.

In this example, the recording medium 1 of the information transmitting device 1
04 is the PCM of the audio signal.
Data, and in that case, the data separation unit 1
06 is divided into summary data and supplementary data by band division as described above, and the data synthesizing unit 124 of the information receiving / recording / reproducing apparatus 2 synthesizes the original PCM signal by band synthesis as described above. Are recorded on the recording medium 126. On the other hand, the information recorded on the recording medium 104 of the information transmitting device 1 may be an audio signal already divided into bands. In this case, the data separation unit 106 converts the audio signal of each band into summary data. The data synthesizing unit 124 of the information receiving / recording / reproducing device 2 restores the original audio signal by rearranging the audio signal of each band into the original data array and records the original audio signal on the recording medium 126. Become.

In this example, the audio signal is separated into a low frequency band and a high frequency band. However, the outline data and the complementary data do not need to be one each.
It is also possible to divide an audio signal into a low frequency band, a middle frequency band, and a high frequency band, and to use any one of the bands as summary data and the other band as complementary data. In this case, the information transmitting apparatus 1 preferentially transmits the audio signal in the band that most affects the reproduced sound quality of the audio signal in the information receiving / recording / reproducing apparatus 2 so that the reception and recording in the information receiving / recording / reproducing apparatus 2 are performed at time t3. Even if the recording was interrupted before, the information receiving / recording / reproducing apparatus 2 can reproduce the original audio signal as closely as possible. Of course, in this example, an audio signal is taken as an example, but it goes without saying that the technology according to the present invention can be applied to an image signal and various other signals.

By the way, in the case of the example shown in FIG. 6, it is necessary to wait a maximum of P1 as a waiting time from the start of reception to the start of reproduction, and in terms of responsiveness from the timing of the instruction of the reproduction selection button 303 for reproduction. Not always enough. Therefore, an example in which the example of FIG. 6 is improved will be described below.

FIG. 7A shows a summary data and supplementary data constituting all the information to be transmitted, which are a plurality of supplementary data, including an information head portion including a head portion of the summary data, and summary data d1 other than the head portion. FIG. 7B shows a state where the data is divided into an information non-leading portion composed of data d2 and d3.
3A shows a state of the transmission information signal in which the divided information is rearranged as shown in FIG.

That is, all the repeatedly transmitted information shown in FIG. 6A corresponds to the information consisting of the information head and the non-information heads d1 to d3 in FIG. 7A. 7 (a), as shown in FIG. 7 (b), the information head is inserted between the outline data d1, the complementary data d2, and the complementary data d3, for example. By repeatedly arranging the information in the non-head part of the information, transmission is performed with a higher repetition frequency than in the non-head parts d1 to d3. Of course, it is also possible to store the transmission information arranged as shown in FIG. 7B in the recording medium 104 of the information transmission device 1, and in that case, omit the processing in the data separation unit 106. Can be.

Next, the arrangement of the information head part and the information non-head part of all the information shown in FIG. 7B is rearranged as shown in FIG. An example of processing until the reproduced information is reproduced in the information receiving / recording / reproducing apparatus 2 will be described with reference to FIG.

FIG. 8 (a) shows the state of repeated transmission of all information, and FIG. 8 (b) shows that the repeatedly transmitted information is received by the information receiving / recording / reproducing apparatus 2 and is recorded on the recording medium 126. The recording timing is shown.

That is, in this processing example, as shown in FIG. 8A, the information transmitting apparatus 1 repeatedly transmits all the information at the time P11.
The information head is repeatedly transmitted at a shorter time P12. At the timing shown in FIG. 8B, the information receiving / recording / reproducing apparatus 2 receives the repeatedly transmitted information and writes it on the recording medium 126.

Therefore, if the viewer is, for example,
At time t11, when an instruction is made to reproduce the information through the reproduction selection button 303 of the information reception / recording / reproduction device 2,
From this time point t11, reception of information and recording on the recording medium 126 are started. Also, at this time, as described above, recording and reproduction on the recording medium 126 are performed in a time-division manner. Playback can be started from. Therefore, the viewer can obtain information from the head of the entire information. Further, the transfer of information to the information receiving / recording / reproducing apparatus 2 ends at time t13, so that the viewer goes out of the reception range at this time t13,
For example, the user may get off the bus, and after that, the information can be reproduced and enjoyed. In the hatched portion of FIG. 8B, the information head is received, but no new recording is performed because the recording on the recording medium 126 of the information receiving / recording / reproducing apparatus 2 has already been completed. This is the part that can be done.

In FIG. 8C, T11 in FIG.
Indicates the playback time of the information head, but the playback time T11 is set to be longer than the time P11. Therefore, when the playback of the information head ends, all the information is received. Recording medium 1 of recording / reproducing device 2
26. Therefore, the reproduction can be continued without interruption. It is easy to make the time T11 longer than the time P11, especially when the bit rate of information transmission is much higher than the bit rate for reproduction. For example, in the example of FIG. 7A, the information head has a reproduction time of 6 minutes, the non-information heads d1 to d3 each have a reproduction time of 18 minutes, and the information transmission bit rate is 60 times the reproduction bit rate. In this case, if the transmission is performed as in the example of FIG. 7B, it is necessary to receive information corresponding to a reproduction time (6 + 18) × 3 = 72 minutes. /60=1.2
The reception is completed in minutes, and the recording of all the information on the recording medium 126 is completed within six minutes, which is the reproduction time of the information head part. The time T12 indicates the reproduction time of the information non-leading portion.

A great advantage of the information transmission method described with reference to FIGS. 7 and 8 is that the maximum value of the waiting time from the start of recording to the start of viewing / listening in the information receiving / recording / reproducing apparatus 2 is as follows.
This is a time period P12 shorter than the time period P11 for transferring all information, thereby improving the response to the reproduction instruction by the reproduction selection button 303.

The information transmitting apparatus 1 separates the information to be transmitted into summary data and complementary data, and transmits the summary data d1, the complementary data d2, and the complementary data d3 in this order. At time t15,
In order to complete the writing of the summary data d1 to the recording medium 126, the viewer goes out of the reception range at the time point t15,
For example, even if you get off the bus, an overview of all information can be obtained by reproducing the overview data. Therefore, even if the end point of the writing to the recording medium 126 of the information receiving / recording / reproducing apparatus 2 is advanced from the time point t13 to the time point t15, the recorded information is established as the outline data. There is no particular problem.

For example, all information is composed of audio signals for one song, and the data separating unit 10 of the information transmitting apparatus 1
6, when the audio signal is separated into a low frequency band component, a middle frequency band component, and a high frequency band component,
The information transmitting device 1 transmits, for example, a middle frequency band component as summary data, and a low frequency band component and a high frequency band component as complementary data d2 and d3. Therefore, the information receiving / recording / reproducing apparatus 2 operates from the time t11 to the time t
13 and receive the summary data d1 and the complementary data d2 and d3, and
By combining the frequency bands into one, it is possible to restore the original audio signal for one tune.

Further, in the same manner as described above, although the information transmitting apparatus 1 starts receiving and recording the outline data d1 (for example, the middle frequency band component) of the audio signal at the time t11, the viewer stays within the reception range until the time t13. Even if it is not possible to stay within the reception range, all the outline data d1 (for example, the middle frequency band component) can be recorded if the stay is within the reception range until time t15, so that the sound quality is lower than the original audio signal. However, it is possible to reproduce an audio signal for one song. The sound quality of the audio signal whose reproduction is started at time t12 is not as good as that of the original audio signal, but the reproduction after time t15 uses the received and recorded complementary data d2 (for example, low frequency band component). The sound quality is improved by performing the reproduction while the reproduction is being performed. Further, in the reproduction after the time point t16, the complementary data d3 (for example, the high frequency band component) received and recorded
, It is possible to reproduce with the sound quality of the original audio signal.

In the above example, the case where the head of one piece of information is repeatedly transmitted is described. However, it is also possible to repeatedly transmit a plurality of pieces of information. It can also be included in the information. FIG. 9 shows an example in which a plurality of pieces of information are repeatedly transmitted and guidance information for the plurality of pieces of information is included in the transmission information.

FIG. 9A shows the contents of the data stored in the recording medium 104 of the information transmitting apparatus 1 in the same manner as FIG. 7A, and FIG. The transmission order of the information shown in FIG. That is, when the information to be transmitted includes, for example, two pieces of information D1 and information D2, the information to be transmitted includes, as shown in FIG. 9A, the guide information and the head of the information D1 (the information D1). Head)
, A non-head part of the information D1 (for example, the outline data d11 and the complementary data d12), a head part of the information D2 (the head of the information D2), and a non-head part of the information D2 (for example, the outline data d2).
1 and complementary data d22).

In this example, for example, guidance information and information D1
The leading part and the leading part of the information D2 are the leading part. That is,
The information to be transmitted shown in FIG. 9A is shown in FIG.
As shown in the figure, the guide information, the head of the information D1 and the information D
2 Regarding the first part, the summary data d11 and the complementary data d
12. By arranging it as a leading part immediately before each of the summary data d21 and the complementary data d22, it is possible to transmit the information D1 at a higher repetition frequency than the non-head part and the information D2 non-head part.

Also in the case of FIG. 9, the reproduction of the information selected by the reproduction selection button 303 is started with a short waiting time and the reproduction is continued without interruption by the same processing as in FIG. Is possible. In the above example, the guidance information, the head of the information D1, and the head of the information D2 are:
Although transmitted at the same frequency, for example, it is possible to further increase the repetition frequency of the guide information.

In the present embodiment, as described above, only the information selected by the reproduction selection button 303 is recorded on the recording medium 126 of the information receiving / recording / reproducing apparatus 2 so that the storage area of the recording medium 126 is effectively used. FIG. 10 shows a control circuit 1 in such a case.
25 shows a control flow.

In FIG. 10, the control circuit 125 first detects, at step S1, a preceding portion that is repeatedly transmitted, and at the next step S2, receives the preceding portion detected at step S1 and stores the information in the recording medium 126. Record.

Next, at step S3, the control circuit 125 reproduces the guide information contained in the preceding part, and determines the reproduction information in the next step S4 according to the instruction of the reproduction selection button 303 of the viewer.

Next, the control circuit 125 sets the number of the reproduction information selected by the viewer in step S4 to J in step S5, and reproduces the head of the information corresponding to the reproduction information number J in the next step S6. At the same time, a non-head part of the information corresponding to the reproduction information number J is received and recorded on the recording medium 126. Then, when the head of the information corresponding to the reproduction information number J has been reproduced, the control circuit 125
In the next step S7, the non-head part of the information corresponding to the reproduction information number J recorded on the recording medium 126 is reproduced.

The case where information is wirelessly broadcast using infrared rays has been described above. However, the method of the present invention can be applied to a case where general wireless broadcast is performed, or to a case of wired broadcast or conventional FIGS. It goes without saying that the present invention can also be applied to the case where information is transmitted by such a method. However, in order to quickly transfer information to a large number of portable information receiving / recording / reproducing devices, it is effective to use the above-described wireless transmission method. In order to transfer information only at a specific place without affecting electromagnetic waves over a wide area, it is particularly effective to use infrared rays.

There is no particular limitation on the type of information.
It is convenient to use the information receiving / recording / reproducing apparatus particularly for audio signals, because the information can be safely reproduced even when it is carried. Further, in the above-described embodiment, a method of transmitting a digitized signal at a high bit rate in order to transmit information at a speed higher than the reproduction speed has been described, but the signal to be transmitted is not necessarily a digital signal. The information receiving / recording / reproducing apparatus may perform analog-to-digital conversion, perform D / A conversion, and record the data on a recording medium. However, when digital signals are transmitted as in the present embodiment, various information can be transmitted in an integrated manner.
