Description

  The present invention relates to a recording / reproducing apparatus, a portable terminal device, a recording / reproducing system, and a recording / reproducing method, and more specifically, one-segment broadcasting (broadcast for portable terminals) and twelve-segment broadcasting (high-vision broadcasting, etc.) included in terrestrial digital broadcasting ) Can be recorded simultaneously, a portable terminal device, a recording / reproducing system, and a recording / reproducing method.

  The ISDB-T (Integration Services Digital Broadcasting Terrestrial) system is known as a standard for digital terrestrial broadcasting in Japan (see, for example, Patent Document 1). The greatest feature of the ISDB-T system is that 13 transmission units called “segments” are multiplexed in a frequency band (1 channel) of about 6 MHz allocated to one carrier. The broadcaster uses 13 segments to simulcast broadcasts for home television (high-vision broadcast, standard broadcast) and broadcasts for mobile terminals. This simulcast is a compound word of “Simultaneous” and “Broadcast” and is also called “simultaneous broadcasting”, which means “simultaneous content” broadcasting.

  In the ISDB-T system, it is possible to divide and multiplex a modulation system that is resistant to noise and multipath for mobile terminals, and a modulation system that is relatively weak to noise for home fixed television, etc. It has become. In general, the resistance to noise and multipath is in a trade-off relationship with the transmission bit rate. The contents to be broadcast are classified according to image quality into the former modulation system for portable terminals (simple video broadcast) and the latter modulation system for fixed television (HDTV broadcast).

  FIG. 13 is a diagram for explaining the outline of the terrestrial digital broadcasting service described in Patent Document 1. In FIG. 13, 300 is a terrestrial digital broadcasting signal for one channel, 301 is a terrestrial digital broadcasting of a broadcaster. A transmission antenna 302 is a television broadcast receiver installed in a home or the like, and 303 is a mobile terminal such as a PDA (Personal Digital Assistant) or a mobile phone. The terrestrial digital broadcast signal transmitted from the terrestrial digital broadcast transmission antenna 301 includes 13 segments T1 to T13. For example, the broadcaster transmits a high-definition broadcast or standard broadcast for the television broadcast receiver 302 in 12 segments (T1 to T6, T8 to T13), and broadcasts to the mobile terminal 303 in the remaining 1 segment (T7). Send.

  In the above, the broadcast for the portable terminal 303 is called “one segment broadcast”, and the number of frames and the frame size are reduced and transmission is performed at a low bit rate as compared with the broadcast for the television broadcast receiver 302. I am doing so. On the other hand, for broadcasting to the television broadcast receiver 302, for example, three standard-definition (SDTV) standard broadcasts using 4 segments, one high-definition (HDTV) high-definition broadcast using 12 segments, and nine segments. There are various patterns, such as one high-definition broadcast using 1 and one standard broadcast using 3 segments, and these are collectively called “12-segment broadcast”.

In “1-segment broadcast” and “12-segment broadcast”, the same programs with different modulation methods are broadcast, and the viewer can watch the broadcast program with the same content as a 12-segment broadcast on the television broadcast receiver 302. It can be viewed as a one-segment broadcast on the mobile terminal 303.
JP 2005-20340 A

  In the use form of terrestrial digital broadcasting as described above, the mobile terminal needs to have a function for receiving and playing back one segment broadcast. However, some existing mobile terminals have a function for receiving digital broadcast. There are playback-only terminals that do not have them. When a program (content) provided by digital broadcasting is to be viewed on such a playback-only portable terminal, it is necessary to record the content on the recording / playback apparatus side.

  However, since the recording / playback apparatus does not have a tuner function for receiving 1-segment broadcasting, there is a problem that the content received and recorded by the tuner for 12-segment broadcasting must be copied or moved to the mobile terminal. .

  Normally, copy-once restrictions are applied to digital broadcasting, and when the content recorded on the recording / playback device is viewed on the mobile terminal, the content on the recording / playback device is erased when the content on the recording / playback device is moved to the mobile terminal. Must. At this time, even when the resolution of the portable terminal is low or the capacity of the HDD is small and it is necessary to down-convert from MPEG-2 to MPEG-4, the content file on the recording / reproducing apparatus must be erased. Even if the content is moved again from the portable terminal to the recording / reproducing apparatus, the high-definition video is lost.

  In addition, when a 1-segment broadcast is received and recorded by a portable terminal equipped with a digital broadcast receiving function, and a 12-segment broadcast of the same content is received and recorded by a recording / playback device, both programs have the same content but are different. Since they are recorded on the device, they are not linked to each other. Therefore, for example, when viewing a part of a program on a mobile terminal and viewing the rest on a television connected to a recording / reproducing apparatus, the television side plays again from the beginning of the program (12 segment broadcast), or It was necessary to perform troublesome work such as rewinding (or fast-forwarding) to the relevant part and replaying.

The present invention has been made in view of the above circumstances, and in a recording / reproducing apparatus having a digital broadcast receiving function, content of 1 segment broadcast (broadcast for mobile terminals) included in digital broadcast and 12 segment broadcast (High-definition broadcasting etc.) content can be recorded at the same time, so that one-segment broadcasting content and its management information can be moved to the mobile terminal,

  FIG. 1 is a diagram showing a configuration example of a recording / reproducing system according to an embodiment of the present invention. The recording / reproducing system has a recording / reproducing apparatus 10 having a terrestrial digital broadcast receiving function and a content reproducing function. The portable terminal 20 includes a dedicated stand 30 for detachably mounting the portable terminal 20. The recording / reproducing apparatus 10 is connected to the dedicated stand 30 via the cable 1, and can communicate with the portable terminal 20 when the portable terminal 20 is attached to the dedicated stand 30. Note that the connection between the recording / reproducing apparatus 10 and the dedicated stand 30 is not limited to a wired connection such as the cable 1 and may be connected via wireless.

  In FIG. 1, a recording / reproducing apparatus 10 includes a hard disk recorder, a DVD recorder, a hard disk integrated DVD recorder, a recorder integrated with a television broadcast receiving apparatus, or a television set that can be connected to a television broadcast receiving apparatus (not shown). It may be a personal computer having a John broadcast reception function and a recording / playback function. The mobile terminal 20 is a portable playback device that can be driven by a battery. For example, the mobile terminal 20 is a mobile phone, a PDA, a terminal having a recording / playback function, a playback-only terminal, or the like.

  FIG. 2 is a block diagram showing an internal configuration example of the recording / reproducing apparatus 10 shown in FIG. 1. The recording / reproducing apparatus 10 includes a receiving unit 11, a segment separating unit 12, a recording unit 13, an input / output interface (input / output I / O). F) 14, a control unit 15, a decoding unit 16, an input unit 17, and an output unit 18. The recording / reproducing apparatus 10 is connected to a television broadcast receiving apparatus (hereinafter referred to as TV) 40 via the output unit 18 and also connected to the portable terminal 20 via the input / output I / F 14. In addition, description of the exclusive stand 30 shown in FIG. 1 is abbreviate | omitted.

  An operation example in the recording process of the recording / reproducing apparatus 10 will be described. The receiving unit 11 is a tuner for receiving an ISDB-T terrestrial digital broadcast signal via an antenna (not shown), and includes a tuning circuit for every receivable channel of the terrestrial digital broadcast signal. Yes. When the user inputs a control signal for recording a desired reception channel (terrestrial digital broadcast) to the input unit 17 by remote control operation or operation of the main body button, the control signal is sent to the control unit 15. The control unit 15 records the content by controlling the segment separation unit 12 in accordance with a control signal from the input unit 17.

  The segment separation unit 12 demodulates the terrestrial digital broadcast signal received by the reception unit 11 using a method corresponding to OFDM (Orthogonal Frequency Division Multiplexing), and performs 13 FFTs on the demodulated broadcast signal. In addition, 12 segments of broadcast signals (hereinafter, 12-segment broadcast signals) and 1 segment of broadcast signals (hereinafter, 1-segment broadcast signals) are separated from the 13 segments. Further, the segment separation unit 12 QAM-demodulates the separated 12-segment broadcast signal, QPSK-demodulates the 1-segment broadcast signal, then 12-segment content (corresponding to the first content of the present invention), 1-segment content (this (Corresponding to the second content of the invention) and output separately to the recording unit 13.

  The segment separation unit 12 outputs the 12-segment content separated from the 13 segments to the decoding unit 16 instead of the recording unit 13 when the 12-segment content is viewed as it is on the TV 40 without being recorded.

  The recording unit 13 is an internal or externally connectable recording medium such as a hard disk, an optical disk (DVD, etc.), a memory card, etc., and a recording area 131 for recording 1-segment content and 12-segment content And a recording area 132. The 1-segment content 131a and its management information 131b are recorded in the recording area 131, and the 12-segment content 132a and its management information 132b are recorded in the recording area 132. Details of the management information 131b and the management information 132b will be described later with reference to FIG.

  Here, in the case of terrestrial digital broadcasting, four modulation schemes such as DQPSK, QPSK, 16QAM, and 64QAM can be selected. However, the modulation scheme in this broadcast is QPSK (4-phase shift keying), 64QAM (Quadrature Amplitude Modulation) is mainly used for 12 segment broadcast signals. Furthermore, in the ISDB-T system, the 1-segment broadcast signal is compressed by MPEG-4 (or H.264) and the 12-segment broadcast signal is compressed by MPEG-2, so the 12-segment content 132a in this example is in the MPEG-2 format. It is assumed that the 1-segment content 131a is compressed in the MPEG-4 format.

  When playing back the 12-segment content 132a recorded in the recording unit 13, the decoding unit 16 decodes the 12-segment content 132a by a decoding method suitable for the MPEG-2 format in accordance with control from the control unit 15. As a result, the 12-segment content 132a is restored to a baseband signal (original video signal and audio signal), and these video signal and audio signal are output from the output unit 18 to the TV 40. When the 12-segment content 132a is reproduced, the control unit 15 refers to resume information, chapter information, and the like included in the management information 132b, and the 12-segment content 132a is reproduced according to the management information 132b.

  On the other hand, the recording / reproducing apparatus 10 is connected to the mobile terminal 20 via the input / output I / F 14, and when there is a content move request from the mobile terminal 20, the 1-segment content 131 a recorded in the recording unit 13 and its management information 131 b is moved to the portable terminal 20 via the input / output I / F 14. Thereby, the user can take out the portable terminal 20 when going out and view the 1-segment content 131a having the same contents as the 12-segment content 132a when going out.

  As described above, the recording / reproducing apparatus 10 can simultaneously record the 1-segment content 131a for the mobile terminal 20, so that the content (12-segment content 132a) having the same content remains in the recording / reproducing apparatus 10 and is portable. Content can also be viewed on the terminal 20. At this time, since it is not necessary to transcode the content, it can be transferred to the mobile terminal 20 in a short time, and the same content can be transferred to both the recording / reproducing apparatus and the mobile terminal regardless of the copy-once limitation of the content. Can be recorded.

  An operation example in the editing process of the recording / reproducing apparatus 10 will be described using the chapter division process as a representative example. The user inputs a chapter division control signal to the input unit 17 by a remote control operation, a body button operation, or the like. The control signal is sent to the control unit 15, and the control unit 15 instructs the recording unit 13 to divide chapters. The recording unit 13 adds or updates chapter information to the management information 132b of the 12-segment content 132a being reproduced. The chapter information is information indicating the position where the content is divided into chapters.

  An example of the operation in the playback stop process of the recording / playback apparatus 10 will be described. The user inputs a playback stop control signal to the input unit 17 by operating the remote controller or operating the body buttons. The control signal is sent to the control unit 15, and the control unit 15 instructs the decoding unit 16 to stop reproduction. The decoding unit 16 stops the decoding process of the 12-segment content 132a from the recording unit 13, and updates the resume information included in the management information 132b based on the stop position at this time. Resume information is information indicating the playback stop position of content.

  When the 12-segment content 132a is stopped or edited before the 1-segment content 131a is moved to the mobile terminal 20, the control unit 15 manages the management information 131b of the 1-segment content 131a and the management information 132b of the 12-segment content 132a. May be updated simultaneously. As another method, the management information 132b of the 12-segment content 132a may be updated first, and the management information 131b of the 1-segment content 131a may be updated according to the management information 132b.

  Thereby, when the 1-segment content 131a and the management information 131b are moved to the portable terminal 20, the portable terminal 20 is taken out and the 1-segment content 131a is viewed on the go, the resume information of the recording / reproducing apparatus 10 is reflected. Therefore, it is possible to view smoothly from the continuation of viewing on the recording / reproducing apparatus 10 (TV 40). Even when the 12-segment content 132a viewed on the recording / reproducing apparatus 10 (TV 40) is edited to create a name scene collection as a playlist, the chapter information of the recording / reproducing apparatus 10 is reflected. There is no need to recreate the playlist at 20.

  FIG. 3 is a block diagram illustrating an internal configuration example of the mobile terminal 20 illustrated in FIG. 1. The mobile terminal 20 includes an input unit 21, a control unit 22, an input / output I / F 23, a recording unit 24, a decoding unit 25, and A display unit 26 is provided. The portable terminal 20 is connected to the recording / reproducing apparatus 10 via the input / output I / F 23, and records the 1-segment content 131 a moved from the recording / reproducing apparatus 10 and its management information 131 b in the recording unit 24. The recording unit 24 is a recording medium that can be built in or externally connected, such as a hard disk, an optical disk (DVD, etc.), and a memory card. Although the description of the dedicated stand 30 shown in FIG. 1 is omitted, when the portable terminal 20 is set on the dedicated stand 30, the input / output I / F 23 and the input / output I / F 14 of the recording / reproducing apparatus 10 are Connected and communicable with the recording / reproducing apparatus 10.

Next, an operation example in the reproduction process of the mobile terminal 20 will be described.
When the user inputs a control signal for reproducing desired one-segment content to the input unit 21 by operating the main body button or the like, the control signal is sent to the control unit 22. The control unit 22 controls the decoding unit 25 according to the control signal from the input unit 21 to reproduce the 1-segment content 131a. The decoding unit 25 decodes the 1-segment content 131a compressed in the MPEG-4 (or H.264) format and restores the original video signal and audio signal.

  When the 1-segment content 131a is reproduced, the control unit 22 refers to resume information, chapter information, and the like included in the management information 131b, and the 1-segment content 131a is reproduced according to the management information 131b. The display unit 26 is a display unit such as a liquid crystal display having a relatively low resolution such as 240 × 320 dots, and displays and outputs the 1-segment content 131a decoded by the decoding unit 25.

  FIG. 4 is a diagram illustrating an example of content management information. The management information includes, for example, content ID, channel name, program name, broadcast time, recording time, information update time, related content ID, resume information (time), chapter information (number of chapters, chapter times 1 to N), and the like. . In the case of the 12-segment content 132a of the terrestrial digital broadcast signal received by the receiving unit 11, the ID of the 12-segment content 132a is recorded as the content ID in the management information 132b, and the ID of the 1-segment content 131a is recorded as the related content ID. Is done. In the case of the 1-segment content 131a, the ID of the 1-segment content 131a is recorded as the content ID in the management information 131b, and the ID of the 12-segment content 132a is recorded as the related content ID.

  By associating in this way, when the recording / reproducing apparatus 10 and the portable terminal 20 are connected, the management information of one of the two contents (12-segment content 132a and 1-segment content 131a) is used to determine the content of the other content. Management information can be specified and updated. At this time, which content management information is to be updated may be set by the user each time, or may be set to either one by default.

  For example, when the user stops playing the 1-segment content 131a viewed on the mobile terminal 20 in the middle of going out, and then tries to view the 12-segment content 132a of the recording / playback apparatus 10 (TV 40), the recording / playback is performed. When the mobile terminal 20 is connected, the control unit 15 of the apparatus 10 acquires the management information 131b of the 1-segment content 131a from the mobile terminal 20, and updates the management information 132b of the 12-segment content 132a with the acquired management information 131b. To do. Thereby, in the TV 40, the reproduction of the 12-segment content 132a can be started from the reproduction stop position of the 1-segment content 131a.

  Conversely, at home or the like, when the 12-segment content 132a that was being viewed on the recording / reproducing apparatus 10 (TV 40) is stopped during playback and the subsequent one-segment content 131a of the mobile terminal 20 is to be viewed, When the recording / reproducing apparatus 10 is connected, the control unit 22 of the portable terminal 20 acquires the management information 132b of the 12-segment content 132a from the recording / reproducing apparatus 10, and the management information of the one-segment content 131a is obtained from the acquired management information 132b. 131b may be updated. As a result, the mobile terminal 20 can start playback of the 1-segment content 131a from the playback stop position of the 12-segment content 132a.

  Further, the recording / reproducing apparatus 10 may include means for obtaining an electronic program guide (EPG), and the EPG may be displayed on the screen of the TV 40 in accordance with an operation from the user. This EPG is a list of broadcast programs for a predetermined period, and is periodically transmitted from a broadcaster or the like, and can be acquired (received) by selecting a predetermined channel. The recording / reproducing apparatus 10 updates the EPG acquired by itself for every predetermined period, and always keeps the latest one.

  When the portable terminal 20 is connected, the recording / reproducing apparatus 10 transmits its own EPG to the portable terminal 20. At this time, the recording / reproducing apparatus 10 determines which one of its own EPG and the EPG already held on the portable terminal 20 side is new, and transmits the EPG if the EPG of the recording / reproducing apparatus 10 is newer. Then, the EPG of the mobile terminal 20 is updated. On the other hand, if both are the same, there is no need to update, so the EPG of the portable terminal 20 is left as it is.

  The portable terminal 20 includes means for generating reservation information for making a recording reservation or a viewing reservation of content based on the EPG from the recording / reproducing apparatus 10. For example, the EPG may be displayed on the display unit 26 under the control of the control unit 22 and the user may make a recording reservation or a viewing reservation on the EPG. In this case, when the portable terminal 20 is connected, the recording / reproducing apparatus 10 acquires reservation information based on the EPG from the portable terminal 20, and performs recording reservation or viewing reservation of content according to the acquired reservation information.

  The recording / reproducing apparatus 10 acquires new content by making a recording reservation as described above, and records the acquired content in the recording unit 13. When the portable terminal 20 is connected, the recording / reproducing apparatus 10 extracts the newly acquired 1-segment content 131a from the recording unit 13, and moves the extracted 1-segment content 131a and management information 131b to the portable terminal 20. You may do it.

Here, since the memory capacity of the mobile terminal 20 is generally small, it is assumed that the memory capacity will soon be insufficient if the new one-segment content 131a is moved randomly.
Therefore, the 1-segment content 131a moved to the mobile terminal 20 may be content that meets predetermined conditions such as recording date, content genre, and recording time. The portable terminal 20 updates the one-segment content that has been viewed or no longer needed by the one-segment content 131a and the management information 131b moved from the recording / reproducing apparatus 10.

  Further, when the portable terminal 20 is connected, the recording / reproducing apparatus 10 extracts the one-segment content 131a designated by the user from the recording unit 13, and moves the extracted one-segment content 131a and management information 131b to the portable terminal 20. You may make it do. In this case, the recording / reproducing apparatus 10 can display a list of one-segment contents 131a recorded in the recording unit 13 on the screen of the TV 40, and contents specified by the user from the list together with the management information can be displayed on the portable terminal 20. Move. The portable terminal 20 updates the one-segment content that has been viewed or no longer needed by the one-segment content 131a and the management information 131b moved from the recording / reproducing apparatus 10.

  Further, the recording / reproducing apparatus 10 may include a means for connecting via a network to a server apparatus that can provide content for mobile terminals. In this case, the recording / reproducing apparatus 10 records the content acquired from the server device (not shown) and its management information in the recording unit 13, and enables the mobile terminal 20 to move the content similarly to the one-segment content 131a described above.

  FIG. 5 is a flowchart for explaining an example of the 1-segment content move process in the recording / reproducing system of the present invention. This example will be described based on the recording / reproducing apparatus 10 shown in FIG. 2 and the portable terminal 20 shown in FIG.
