Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital broadcast receiving and storing apparatus for digital broadcasting, and more particularly to a digital broadcast receiving and storing apparatus for automatically storing program information in accordance with settings.

[0002]

2. Description of the Related Art In the present specification, it is assumed that program (content) information includes not only a program composed of video and audio but also a program composed only of audio and a program composed only of data.

In general, in digital broadcasting, program-related information called SI (Service Information) is multiplexed and transmitted together with signals constituting programs such as video and audio. At the receiver, the EPG (Electric Program Guide) is generated based on the SI according to the user's request.
An electronic program guide called “Electronic Program Guide” is created and presented to facilitate program selection.

In recent digital broadcast receiving and storing apparatuses, recording of a program (recording) can usually be reserved from the EPG. The receiver stores and manages the program reserved for recording by the user, and monitors a start time / end time of the program, and connects to a digital VTR (video tape recorder) such as a D-VHS (digital VHS). : VideoTap
e Recorder) and the signal output to an analog VTR.

[0005] When the target of recording reservation is a pay program such as PPV (Pay-Per-View), the user knows the recording fee at the time of reservation and judges in advance whether recording should be performed. The purchase / recording process will be performed.

In recent digital broadcast receiving and storing apparatuses, a receiver determines a program desired by a user by using a storage device such as an HDD (Hard Disk Drive) whose capacity is increasing. A function of automatically accumulating the information and allowing the user to reproduce and view the image at any time is considered. For example, program title and genre,
The preferences of the users such as the performers are registered in the receiver in advance, and the receiver detects the corresponding program from the program information and performs the accumulation processing based on these.

[0007]

However, when the above-described automatic storage function is executed, the receiver checks the user's intention when the program is a pay program and is subject to recording and charging (a contract form charged at the time of recording). There is a problem that the purchase process is performed without doing so, which is disadvantageous for the user. Playback billing (contract form that is not charged for recording but is charged for playback)
Even in the case of the target, if the user does not confirm the user's intention and accumulates, even if the purchase processing is not performed, the storage capacity is insufficient, and the accumulation of other programs that the user really desires is hindered. .

An object of the present invention is to provide a digital broadcast receiving / storing device that performs a storage process after determining whether or not information desired by a user satisfies a storage condition, in order to solve the above-described problem.

[0009]

The MPEG video decoder 27 stores the decoded video frames in a DRAM (dynamic random access memory, not shown) while storing the decoded video frames in the MPEG video decoder 27.
A signal encoded by the G2 video high-efficiency encoding method is decoded and output as Y, Cb, and Cr digital component signals. Further, if necessary, the graphic output of the OSD processor 30 and the adder 31 are superimposed and output. Similarly, the audio is compressed and decoded by the MPEG / AC3 audio decoder 28 and output.

Although not shown in the figure when the digital broadcast receiving / storing device outputs an analog signal, the video output of the adder 31 is output, for example, via an NTSC encoder to an NTS encoder.
The signal is converted into a C analog composite signal and output. The output of the MPEG / AC3 audio decoder 28 is output to an audio D / A unit, converted into an analog audio signal, and output.

A microcontroller 32 is provided to appropriately perform these signal processes, and supports peripheral devices. For example, microcontroller 3

When the start of recording of a program of a specific service is designated from the multiplexed signal of the digital broadcast being received by a recorded program selector such as a remote controller, the microcontroller 32 having received the notification notifies the real-time reproduction of the broadcast signal. As in the case described above, the designated program-related information is analyzed, and each transmission identifier is set in the transport processor 25 and the descrambler 23. As a result, the transport processor 25 demultiplexes necessary signals and outputs them to the recording / reproducing device 33 via the digital interface 34.

The SIT is created by the SIT creating unit 38 by extracting and editing only the information related to the program or service selected and recorded from the SI multiplexed in the broadcast signal by the selection information creating unit. Are multiplexed in the recording signal. The DIT is also inserted into the recording stream by the DIT creator 37 as an indication of the point where the SI information may become discontinuous in the discontinuity information creator and output.

In the case of the accumulation / reproduction processing, both the selectors 24 and 35 select and output the input on the recording / reproduction processing side. The transport processor 25 selects a predetermined service designated by a recorded program selector 36 such as a remote controller from among the multiplexed signals in the TS format, as in the case of the broadcast reception / playback, and displays the video and video constituting the program. The audio signal is demultiplexed, subjected to depacket processing, returned to the respective compressed signals, and converted to the MPEG video decoder 17 or MPEG / AC3.
Output to the audio decoder 28. Also, the PSI and SIT program-related information multiplexed together with video and audio are separated and output to the program-related information reproducer 29.

Here, the accumulation control processing according to the present invention will be described in detail below with reference to flowcharts. Regarding the automatic accumulation processing, the actual accumulation processing is executed when the start time comes after the accumulation reservation.

First, regarding the storage reservation processing, the above-mentioned microcontroller 32 controls the storage reservation processing in a procedure as shown in the flowchart of FIG. 1, for example. In addition,
In this example, it is assumed that the storage target is a normal program composed of a video / audio stream, and that the storage or reproduction expiration date information is transmitted together with the program.

First, under the control of the microcontroller 32, conditions for a program to be stored, that is, search conditions are set, and in this case, a title is set (S11).
Of course, various search conditions can be set.
Next, as a storage condition, the expiration date threshold (E
_th ) is set (S12). Of course, various accumulation conditions can be set here. With these settings as a preparatory stage, the SI
Then, program related information such as is monitored (S13). When an update of this information is detected (S14), a process of acquiring the information and converting it to an internal database is performed (S15).

Next, a search pointer of this database is set (S16), and a search is started for each program according to the search conditions set in step S11 (S17). If there is program information that matches the set title (S18),
Further, the expiration date is checked, and if this value is equal to or _larger than the threshold value _Eth (S19), this program is registered in the storage reservation management table (S20). Then, it is determined whether or not the search is completed (S21). If the search is not completed, the search pointer is incremented and set to the next search unit (program) (S2).
2) Thereafter, the processing from step S17 to step S21 is repeated until the search is completed. Step S
If the search is completed at 21, the process returns to step S13, and monitoring of the program-related information is continued.

Next, the accumulation processing performed in accordance with the accumulation reservation management table created in step S20 will be described in detail with reference to the flowchart of the accumulation processing in FIG.

In FIG. 3, a threshold value (D _th ) of the remaining capacity of the storage medium is set in advance (S31). Then, the start time of the program reserved for storage created in the flowchart of FIG. 1 is monitored (S32), and the measured current date and time t is the time obtained by subtracting at least the time T1 in consideration of the following remaining capacity confirmation processing from the start time. It is checked whether the time has elapsed (S33). If it has not elapsed, the process returns to step S32 to continue monitoring the start time of the program, and if it has elapsed, the remaining capacity of the storage medium at this point is checked (S3).
4).

If the remaining capacity is equal to or less than the threshold value _Dth (S
31) It is checked whether there is content that does not completely satisfy the storage condition set by the user but is temporarily stored (S).
35). If such content exists, the content is deleted (S36), and the process returns to step S34. If not, a message indicating that the remaining capacity is insufficient is displayed (S37).

Further, the start time of the program is monitored (S3
8) It is confirmed whether or not the current date and time t has elapsed from the start time by subtracting at least the time T2 that takes into account the processing time required to start the following accumulation execution (S39).
However, it is assumed that 0 ≦ T2 ≦ T1. If not, the process returns to step S38 to continue monitoring the start time of the program.

Here, if the time has elapsed, the storage process is executed (S40), and the end time of the program is monitored (S41). Further, it is confirmed whether the current date and time has passed the end time (S
42), if this condition is not satisfied, step S40
Repeat the following. If satisfied, an update process is executed in the reservation management table in accordance with the end of the execution of the recording reservation of the program (S43), and the accumulation process ends.

As described above, for a program to be stored, for example, a threshold value of an expiration date is set and determined as a storage condition, and a program (content) is stored, and then a user's intention regarding storage of program (content) information is determined. In this case, the use efficiency of the storage capacity can be improved, and the lowest cost and desired automatic program information storage processing can be performed for the contract form charged at the time of recording.

In the above description, the case where the program title is set as the automatic search condition and the match is performed has been described with reference to the flowchart. However, keywords such as performers and genres such as sports and dramas are set. You may. Further, it may be set to store contents other than the stream format distributed in a certain time zone, and it is also possible to set a plurality of these.

Further, as for the storage conditions, other than the reproduction expiration information, information relating to contract matters such as a purchase price, control information relating to storage reproduction such as the maximum number of reproductions, etc. are used as storage conditions. Such as setting
Various conditions can be set as accumulation conditions.

<Second Embodiment> In a second embodiment, a storage condition set by a user is automatically updated based on a subsequent storage operation, and program (content) information is updated in accordance with the updated storage condition. Is to specify a digital broadcast receiving / storing device that further accumulates or updates the data. FIG. 4 is a flowchart showing a storage reservation process of the digital broadcast reception / storage device according to the second embodiment of the present invention, and FIG. 5 is a flowchart showing a deletion process.

Here, the second embodiment is described by using a case where a program whose purchase price is equal to or less than a certain value is stored, and when a program cheaper than the program is detected, the program is updated and stored.
This will be described below with reference to the flowchart of FIG.

In this example, it is assumed that the target content is charged for reproduction. In the flowchart of FIG. 4, a title is set here as a condition of a storage target program, that is, a search condition (S51). Next, a threshold value (P _th ) of the purchase price of the program is set as an accumulation condition (S52). These settings are set as a preparation stage, and program-related information such as SI is monitored from input signals distributed thereafter (S53). When the update of this information is detected (S5
4) A process such as acquiring this and converting it into an internal database is performed (S55).

Next, a search pointer in the database is set based on the set search conditions (S56), and a search is started for each program (S57). The value matches the set title (S58), and the purchase price is further checked.
If it is not less than _th (S59), this program is first referred to the storage reservation management table (S60), and it is confirmed whether or not a program which has not been stored under the same conditions but has already been reserved already exists. (S61). If the reservation already exists, the reservation registration of the program is canceled (S62), and the storage reservation is newly executed (S63) so that the purchase price threshold value, which is the storage condition, becomes a value lower than before. Update (S
64).

Then, it is determined whether the search is completed (S6).
5) If the search has not been completed, the search pointer is incremented and set to the next search unit (program) (S66), and thereafter, the steps from step S57 to step S64 are repeated until the search is completed. Step S65
When the search is completed, the process returns to step S53, and the monitoring of the program-related information is continued.

Next, an example of the accumulation deletion processing will be described below with reference to the flowchart of FIG. In the flowchart of FIG. 5, referring to the stored program (S7
1) Check whether the same program exists (S7)
2). If it exists, it is further checked whether or not it has not been purchased (S73). If it has not been purchased, the stored program is deleted (S74). This deletion process can be executed at an arbitrary timing after the above-mentioned accumulation reservation process. However, if the deletion process is executed before the actual accumulation process of the accumulation reservation, the storage capacity can be used efficiently.

As described above, when the storage target corresponding to the search condition is detected, the purchase price is confirmed, and when there is a target program that has already been reserved for storage or has been stored but has not been purchased, the purchase price is checked. By providing a function of updating if the cost is low compared to the above, automatic accumulation suitable for the user's benefit can be realized.

Specifically, when a purchase price of 500 yen is initially set and program (content) information of 400 yen is actually stored, the subsequent purchase price is set from 500 yen to 400 yen. This is the case when re-starting. Therefore, after updating the storage condition, the program (content) information of 450 yen is not stored, and the program (content) information of 250 yen is stored.

In the above description, a case has been described in which a program title is set as a search condition for automatic storage and matches, but keywords such as performers can be set, sports,
A genre such as a drama may be set. In addition, a case where content other than the stream format distributed in a certain time zone, which is not limited to the program frame, may be stored. Further, the first embodiment may also be applied to storage control based on control information related to storage and reproduction other than the purchase price information, for example, information on reproduction expiration date and maximum number of reproduction times.
This is the same as in the embodiment.

<Third Embodiment> In a third embodiment, a program (content) searched for under a search condition is first stored, and then a stored program (content) that does not satisfy the storage condition is deleted. The device is specified. FIG. 6 is a flowchart showing the storage processing of the digital broadcast receiving and storing apparatus according to the third embodiment of the present invention, and FIG. 7 is a flowchart showing the deletion processing.

In FIG. 6, in the third embodiment, a program title as an example of a search condition is set (S11), and an expiration date as an example of a storage condition is set by the same procedure as in the first embodiment. (S12). The following processing is almost the same as that of FIG. However, as shown in the flowchart of FIG. 1, storage reservation registration is performed without the step of confirming the expiration date, which is an example of the storage condition, in step 19 (S20). Thereafter, the program (content) information for which the storage reservation has been registered is stored in accordance with the procedure shown in the flowchart of FIG. Thus, in the third embodiment, program (content) information is stored without determining the storage condition.

Thereafter, according to the flowchart shown in FIG. 7, the stored program (content) information is appropriately deleted. For example, when unnecessary program (content) information is deleted in response to a user operation (or by setting deletion processing in advance at regular intervals) due to a lack of storage capacity of an HDD or the like. If it becomes (S8
1) It is confirmed that the accumulation process is not currently being performed (S82). If the storage processing has not been performed, it is determined whether the program (content) information whose storage has been completed conforms to storage conditions such as a price and an expiration date (S8).
3). If the storage condition is not satisfied, this is deleted. If the storage condition is satisfied, the standby state is entered without deletion.

As described above, according to the third embodiment, when registering a storage reservation, only search conditions such as titles are determined, and program (content) information suitable for the search conditions is uniformly stored. After storage, it is determined whether or not storage conditions such as a price and an expiration date are satisfied, and inappropriate program (content) information is deleted. According to such a method, similarly to the first embodiment, it is possible to automatically perform the process of storing program (content) information in response to a user's detailed request.

[0049]

As described above in detail, according to the present invention, by setting the storage conditions desired by the user such as the purchase price and the expiration date together with the search conditions such as the title, the program desired by the user ( It is possible to provide a digital broadcast receiving and storing apparatus capable of automatically storing only content) information with high efficiency.
