  FIG. 3 is a block diagram showing functional configurations of the portable receiving terminal 1 and the television receiver 31 in the device control system 100. As shown in FIG. 3, the mobile reception terminal 1 includes a main storage unit 2, a control unit 3, a RAM 4, an input unit 5, a channel selection information extraction unit 6, a control signal generation unit 7, a control signal transmission unit 8, and a terminal tuner unit. 10, a speaker 11, a terminal projection unit 15, and a display unit 16, and these units are connected to each other via an internal bus 17.

  The main storage unit 2 is, for example, a semiconductor memory, an HDD, an optical disk, or the like, and information relating to a remote controller of a manufacturer such as a television receiver 31 or a video recorder 41 to be used in advance (that is, a remote control code for remotely controlling these devices) Etc.). If it is not stored in advance, it is obtained by downloading from the manufacturer's public site.

  The control unit 3 is a microcomputer including a ROM or the like that stores a control program, for example, and controls the operation of each unit of the mobile reception terminal 1.

  The input unit 5 includes, for example, a numeric keypad and buttons, and receives instructions and characters from the user.

  The channel selection information extraction unit 6 specifies information indicating the channel selected by the terminal tuner unit 10.

  The control signal generation unit 7 generates a control signal corresponding to a remote control code of the television receiver 31 (that is, the television receiver 31 can be identified). More specifically, the control signal generation unit 7 acquires a remote control code of the television receiver 31 via the internal bus 17 and uses information indicating the channel specified by the channel selection information extraction unit 6, A remote control signal for controlling the channel selection of the television receiver 31 (for example, the channel selection of the portable receiving terminal 1 and the television receiver 31 is matched) is generated.

  The control signal transmission unit 8 transmits the remote control signal generated by the control signal generation unit 7 by infrared rays or the like.

  The terminal tuner unit 10 receives and demodulates a one-segment broadcast of terrestrial digital television broadcasting, generates a data stream, and transmits this data stream to the terminal projection unit 15.

  The speaker 11 outputs the audio in the received one segment broadcast. In place of the speaker 11, an earphone jack or the like may be provided.

  The terminal projection unit 15 decomposes the data stream demodulated by the terminal tuner unit 10 into image data and audio data. The terminal projection unit 15 includes a system decoder unit 12, an AV decoder unit 13, and a graphic control unit 14. The operation of the terminal projection unit 15 will be described later.

  The display unit 16 is, for example, a QVGA (Quarter VGA: 320 × 240 pixels) type liquid crystal panel of several inches, and presents a one-segment broadcast screen and necessary information.

  Next, operations of the terminal projecting unit 15 and the channel selection information extracting unit 6 will be described with reference to FIGS. 5 to 7, 9 and 10.

  As shown in FIG. 6, the program program of “XXch” selected by the terminal tuner unit 10 is a transport stream (TS) defined by the MPEG2 standard and including TS packets (188 bytes) as a constituent element. Is output as This TS packet includes a PID, an adaptation field, and a payload, and each information can be identified by the value of the PID. In the adaptation field, a program time reference value such as PCR and stuffing for a length of 188 bytes are transmitted, and the payload includes actual divided video, audio, data, and the like. A stream that needs to be reproduced in synchronization with time such as video, audio, or caption data is transmitted in a PES packet format, and additional data such as data broadcast is transmitted in a format called a section. Therefore, by connecting the payloads of the same PID, each component such as video, audio or data can be separated and restored.

  That is, necessary data is restored by a process as shown in FIG. In particular, since additional data such as data broadcasting is configured in a section format, a section filter can be configured by further setting section conditions, and the additional data can be separated into necessary types.

  In 1-segment broadcasting, a NIT (Network Information Table) is inserted into the TS in a section format in a predetermined fixed value PID. This NIT specifies the PID of the PMT in which the PID of the component such as video, audio, or data of each program is described, and information (for example, remote control ID) for associating the transmission path information with the broadcast program. Therefore, it is possible to select a NIT with a predetermined fixed value of PID from the TS for one segment broadcast, and extract the additional data of the one segment broadcast and the PID of the necessary component from the contents of the NIT. FIG. 5 shows a summary of each data hierarchy.

  That is, when receiving the TS from the terminal tuner unit 10 described above, the system decoder unit 12 acquires the NIT from the fixed value of the PID, further acquires the PID of the PMT from the NID data, and acquires the PID of each component from the PMT. Then select the necessary data in order.

  Next, the video and audio output from the system decoder unit 12 are input to the AV decoder unit 13, the audio is decoded according to the “MPEG2 AAC standard” and output as audio from the speaker 12, and the video is “H.264”. Decoded according to the “standard” and output to the graphic control unit 14. Here, the MPEG2 AAC standard and the H.264 standard are used. A detailed description of decoding in the H.264 standard is omitted.

The display unit 16 displays an image in accordance with an instruction from the graphic control unit 14.

  Information relating to the program program output from the system decoder unit 11 is temporarily stored in the RAM 4 via the internal bus 17.

  The NIT describes a physical channel, a broadcasting station name, a remote control ID (remote control key number), and a service ID. As the service ID, IDs of up to three types (the number of program formations allowed for a physical channel and up to three types in the case of SD-TV) are permitted, and are given according to the type of program formation.

  Further, it is possible to specify a 3-digit channel number that can be directly selected from the service ID by the remote controller, and further to specify the PID value of the PMT according to the program organization. That is, even in 1-segment broadcasting, as in 13-segment broadcasting, three types of programs can be transmitted, and the above three types of programs can be identified by the service ID. Usually, in 1 segment broadcast, the same program as 13 segment broadcast is broadcast.

  Next, using the tables of FIGS. 9 and 10, information indicating the channel is extracted using the NIT used in the one-segment broadcasting in the Kanto region and the NIT used in the one-segment broadcasting in the Kansai region. An example will be described.

  The device control unit 25 is a microcomputer that includes a ROM or the like that stores a control program, and controls the operation of each unit of the television receiver 31. Further, the device control unit 25 decodes the received remote control signal and executes necessary control for the television receiver 31 and other devices connected to the television receiver 31. For example, when information indicating the channel is included in the remote control signal, the device tuner unit 22 is instructed to change the channel selection of the television receiver 31 using this information.

  The display unit 26 is configured by any one of a liquid crystal device configuration, a CRT device configuration, and a PDP device configuration, and the display unit 26 displays an output signal of the device projection unit 23.

  The audio signal output from the device projection unit 23 is output from the speaker 27.

  Here, the device control unit 25 notifies the user that the display has been switched to the channel corresponding to the communication information terminal 1, so that the operation information such as the channel code is displayed as character information in accordance with the device video output 23. May be commanded and displayed on the display unit 26.

  The digital IF unit 30 controls data exchange with a device such as a video recorder 41 connected to the outside of the television receiver 31. Specifically, the digital IF unit 30 may be configured with either a configuration of the IEEE 1394 standard or a configuration of the HDMI standard. According to each standard, whether or not other devices are connected, whether the power is on / off And the television receiver 31 is controlled in accordance with these states. For example, when the power source of the television receiver 31 is in the “OFF” state, the power source can be set to the “ON” state, and control can be performed so that each signal can be received and video can be reproduced.

  Here, the 1-segment broadcast and the 13-segment broadcast in the terrestrial digital broadcast which are the premise of the present invention will be described.

  FIG. 4 is a diagram illustrating physical channel assignment.

  In addition, for SD-TV (the required rate for video and audio source signals is 124 Mbps), the remaining 4 segments broadcast 1 ch (1 program), that is, 12 segments 3 ch (3 programs).

  FIG. 8 is a table summarizing differences in functions between 1-segment broadcasting and 13-segment broadcasting.

  In 1-segment broadcasting, video signals are broadcast at QVCA (320 × 240 pixels), 15 frames / second (fps), so the audio signal is also “5.1ch multi-surround mode” (hereinafter referred to as “low-rate”). , "5.1ch multi"), and data broadcasting (caption function, etc.) is also used for low rate "C profile, BML version 12" The broadcast is suitable for a display monitor size of 1 (about 2 inch size). In addition, 1-segment broadcasting in terrestrial digital broadcasting is positioned as supplemental broadcasting, and the programs broadcast in 1-segment broadcasting are 13-segment broadcasting and the same program is broadcast at the same time.

  On the other hand, in 13-segment broadcasting, broadcasting compatible with HD-TV, SD-TV, or 5.1ch multi is enabled.
