The present invention relates to a method and apparatus for recording broadcast content, and more particularly, to a system, apparatus, and method for recording broadcast content based on a plurality of recording terminals.

Currently, an electronic program guide (EPG) is used as a representative application for providing information of digital broadcasting content and managing reservation of viewing or recording of broadcasting content. The EPG information is guide information for various programs that are broadcast through digital terrestrial broadcasting, IPTV or cable broadcasting, and helps the viewer to select a program and displays program information selected or reserved by the user.

In addition, broadcast receiving devices are becoming more complex and various products are being released according to the trend of widespread distribution and high-end. Among them, a personal video recorder (PVR) is a personal digital video recorder that records and plays back information on a hard disk. Unlike a VCR, which stores video signals on a magnetic tape, it records and plays information on a hard disk. It is a new concept digital recording device. It is a next-generation recording device that can record a certain amount of broadcast content according to its capacity without a VCR through a hard disk drive built into a set-top box or a television body.

When the PVR selects a channel, the signal currently broadcasted to the hard drive can be digitally stored and played simultaneously. Therefore, if the stop button is pressed and the play button is pressed again, the stored broadcast signal is played again from the point where it was stopped. You can also watch the content that is currently being broadcast, play it back in slow motion, and jump over boring parts, making it easy to find and edit the parts you want.

 That is, the personal video recording device provides not only basic recording but also various timing functions to satisfy timing needs, intermediate playback while watching live broadcasts, and other users. Moreover, the advantages of storing HD-quality high-definition digital broadcasting at any time on the hard disk and various additional service functions exist as a great attraction for the user, and the demand is rapidly increasing and numerous new technologies are being developed.

Accordingly, an environment in which viewers can access vast amounts of digital broadcasting contents is being established. As a result, the amount of content stored in the PVR will also be vastly incomparable with current conditions. Therefore, a case where the storage capacity of the storage device included in the PVR is insufficient may occur.

In addition, with the diversification of digital broadcasting and the provision of video on demand (VOD) service or CAS (Conditional Access System), content that can be received only by a specific receiving device is increasing. In addition, reception may not be possible depending on the state of the network. Therefore, there may be broadcast content that can be received only in a specific PVR, and only the specific PVR should be used to record the broadcast content.

Information indicating the recording of the content may be transmitted.

As described above, with the rapid development and generalization of digital broadcasting technology, numerous digital broadcasting channels in various forms have emerged. Accordingly, an environment in which viewers can access a vast amount of digital broadcasting contents has been established. Accordingly, broadcast contents that can be recorded by the recording terminal are also increasing, and the amount of content to be stored will also be vastly incomparable with current conditions. Meanwhile, due to the development of a home network such as DLNA, a plurality of broadcast content receiving devices and recording terminals are often present in a home, and the plurality of broadcast content receiving devices and recording terminals may be connected to each other via a home network. have.

Accordingly, when a plurality of terminal-based broadcast content recording system 100 according to an embodiment of the present invention intends to record a plurality of broadcast contents in a home network environment, a plurality of recording terminals corresponding to the plurality of broadcast contents are used. Each broadcast content may be recorded. For example, as illustrated in FIG. 1, when a user wants to record four broadcast contents, a plurality of (eg, four) recording terminals 110-1 using the recording terminal control apparatus 200 are used. , Based on 110-2, 110-3, and 110-4, the broadcast content to be recorded in each recording terminal may be set, and the respective recording terminal may be controlled to record the corresponding broadcast content according to the setting.

Recording terminal control device

2 is a block diagram showing a configuration of a recording terminal control apparatus according to an embodiment of the present invention. Hereinafter, the configuration and operation of the recording terminal control apparatus 200 will be described in more detail with reference to FIG. 2.

As shown in FIG. 2, the recording terminal control apparatus 200 according to an exemplary embodiment of the present invention may include a receiver 210, a controller 220, and a transmitter 230.

The reception unit 210 is information related to broadcast content that can be recorded by the plurality of recording terminals 110-1, 110-2, and 110-3 from the plurality of recording terminals 110-1, 110-2, and 110-3, respectively. Broadcast content information including the terminal and the terminal information associated with each of the plurality of recording terminals (110-1, 110-2, 110-3) can be received.

A plurality of recording terminals 110-1, 110-2, and 110-3 or broadcast receiving apparatuses (not shown) connected to the plurality of recording terminals 110-1, 110-2, and 110-3 respectively receive the signals. The broadcast content that may be different may be different. Broadcast content providers who provide broadcast content may be different, and even when receiving broadcast content through the same broadcast content provider, channels provided according to service selection may be different. In addition, when the VoD service is provided, only the recording terminal applying for the VoD service may receive specific content.

Accordingly, the receiver 210 broadcasts each of the recording terminals 110-1, 110-2, and 110-3 from the plurality of recording terminals 110-1, 110-2, and 110-3. Broadcast content information including information related to the content may be received.

4 is an exemplary view of broadcast content information according to the present invention.

As shown in FIG. 4, the broadcast content information 310 may include at least one of a broadcast channel, a broadcast time, a content length, and content capacity information. For example, specific broadcast content is broadcast on channel '7', broadcasting starts at '7:30', broadcasting continues for '1 hour 30 minutes', and the specific broadcast content is '700 MB'. Information indicating a capacity can be obtained through the broadcast content information.

Referring back to FIG. 2, since the receiver 210 has received the broadcast content information from the recording terminals 110-1, 110-2, and 110-3, the recording terminal control apparatus 200 includes the home. Information on all broadcast contents that can be recorded on the network can be obtained.

In addition, the receiving unit 210 is terminal information associated with the state of each of the plurality of recording terminals (110-1, 110-2, 110-3) from the plurality of recording terminals (110-1, 110-2, 110-3). Can be received. As described above, as broadcast contents are diversified and enormous, certain recording terminals have already recorded and stored a large amount of broadcast content, and as a result, there is insufficient remaining storage capacity, which means capacity for recording and storing broadcast content. have. In addition, even when the remaining storage capacity is sufficient, the recording of the specific broadcast content cannot be recorded if recording of other content is already reserved at the time of recording the specific broadcast content.

5 is an exemplary diagram of terminal information according to the present invention.

As illustrated in FIG. 5, the terminal information 320 may include at least one of a reserved recording schedule, a remaining storage capacity, a terminal performance, a terminal state, and a network condition of a recording terminal corresponding to the terminal information.

For example, the recording terminal corresponding to the terminal information 320 is broadcast for '40 minutes 'starting from channel' 7 'to '18: 20' to record broadcast content occupying a capacity of '600 MB'. It is reserved. Therefore, other broadcast contents cannot be recorded from '18: 20 'to '19: 00'.

Since the recording terminal corresponding to the terminal information 320 has a remaining storage capacity of '1077642 MB', other recording contents may be further recorded if the recording terminal does not overlap with the reserved time. In the recording terminal corresponding to the terminal information 320, the performance of the terminal is 'S' level, the status of the terminal is 'S' level, and the current state of the network connected to the recording terminal is 'A' level. Here, each of the grades may be classified based on the stored grade table.

Referring back to FIG. 2, the controller 220 may determine which of the plurality of recording terminals to record a specific broadcast content based on the broadcast content information and the terminal information received by the receiver 210. .

For example, when the same broadcast content information 310 is received from the recording terminal 110-1 and the recording terminal 110-2, and the terminal information 320 is received from the recording terminal 110-2, In order to record 37 minutes of '472 MB' capacity starting at '17: 50 'of channel 6, the recording terminal 110 has already been reserved for recording channel 7 of content at 18:20. It may be determined that the recording is performed through the recording terminal 110-1, not -2).

In addition to the reserved recording schedule of the recording terminal corresponding to the terminal information, the recording terminal to record the specific broadcast content may be determined based on at least one of remaining storage capacity, terminal performance, terminal status, and network conditions.

For example, when the remaining storage capacity of the recording terminal 110-3 is 680 MB, the recording terminal 110-3 may record '6' among the broadcast contents included in the broadcast content information 310 of FIG. 4. The contents other than the broadcast contents broadcast in channel 1 cannot be recorded.

In addition, based on at least one of terminal performance, terminal status, and network conditions among recording terminals capable of receiving the same broadcast content, a terminal having better performance may determine to record specific broadcast content.

Referring back to FIG. 2, the transmitter 230 may transmit information indicating recording of the specific broadcast content to the recording terminal determined by the controller 220. When the broadcast of the specific broadcast content has already started, the transmitter 230 may transmit information indicating to start recording immediately to the recording terminal, and if the broadcast of the specific broadcast content has not started yet, Information indicating to schedule recording may be transmitted to the recording terminal.

Here, when the recording terminal completes recording of the specific broadcast content, the recorded broadcast content may be shared between devices included in a home network including the recording terminal control device. Therefore, when recording of the specific content is completed, the receiver 210 may receive URL information of the recorded content from the determined terminal. The URL information may include at least one of a name, a path name, and a recording file name of a recording terminal on which the recording is performed, and the recording terminal control apparatus 200 may obtain and play the recorded broadcast content based on the URL information. have.

When the recording of the specific content is stopped, the receiver 210 may receive a reason why the recording is stopped from the determined terminal. Receiving a reason why the recording of the specific content is stopped, and providing the user of the recording terminal control device with the reason that the recording is stopped, the user of the recording terminal control device can give up recording or try again. .

The receiving unit 210 may receive a recording request of specific broadcast content from at least one recording terminal. The recording terminals 110-1, 110-2, and 110-3 may receive the recording terminals 110-1, 110-2, and 110-3 even though the recording terminal controller 200 does not pass through the recording terminal control apparatus 200. Broadcast content can be recorded. However, when recording of a specific broadcast content is not possible, for example, when the remaining storage capacity of the terminal is insufficient or the network is in a bad state, the recording terminals 110-1, 110-2, and 110-3 may be used. The receiver 210 may transmit a request for recording specific broadcast content. The receiver 210 is capable of recording the specific content among all the recording terminals 110-1, 110-2, and 110-3 connected to the recording terminal control apparatus 200 based on the received recording request. The recording terminal may control to record the specific broadcast content.

As broadcast contents become widespread and companies providing various broadcast contents services have emerged, it is possible to allow specific broadcast contents such as a CAS (Conditional Access System) only to a broadcast receiving device having the right to receive the specific broadcast contents. There may be cases. Scrambling broadcast content and descrambling the scrambled broadcast content through a smart key included in the broadcast receiving device having the right.

Accordingly, the CAS-applied broadcast content can be recorded only by a recording terminal having a smart key and a right corresponding to the CAS-applied broadcast content. If the specific content to be recorded by the recording terminal control device 200 is a content to which a Conditional Access System (CAS) is applied, the terminal information further includes a smart key and authority holding information, and the control unit 220 is smart. The terminal for recording the specific content may be determined among recording terminals having a key and a right.
