  By the way, in terrestrial digital broadcasting, broadcasting for an in-vehicle or portable broadcast receiving apparatus used for viewing a program outdoors is scheduled. Therefore, it is conceivable that such a broadcast receiving apparatus also accumulates a program viewing history. On the other hand, even in a broadcast receiving apparatus fixedly installed at home or the like, viewing history is accumulated separately. In addition, when a new broadcast receiving device is replaced, the new broadcast receiving device starts accumulating viewing history from scratch, and the viewing history accumulated in the old broadcast receiving device is wasted.

  In view of the above circumstances, an object of the present invention is to make viewing history information stored in a certain receiving device available to other receiving devices.

  In order to solve the above-described problem, the broadcast receiving apparatus of the present invention is a broadcast receiving apparatus that receives a broadcast.

  In the first configuration, a predetermined key may be provided, and when the predetermined key is operated, a process of transferring the viewing history information to another receiving device may be performed.

  Further, the broadcast receiving apparatus of the present invention comprises a communication means for receiving viewing history information transferred from another receiving apparatus in a broadcast receiving apparatus that receives a broadcast, and a means for storing the received viewing history information. And processing means for executing a predetermined process based on the accumulated viewing history information (hereinafter referred to as a second configuration in this section).

  With the above configuration, the viewing history accumulated in another receiving device can be used in the own device.

  In the second configuration, there is provided means for accumulating viewing history information of a program received by the own device, and new viewing based on the viewing history information and viewing history information transferred and accumulated from the other receiving device. It may be configured to create history information.

  Also, the broadcast receiving apparatus of the present invention is a broadcast receiving apparatus that receives a broadcast, a communication means for receiving viewing history information transferred from another receiving apparatus, and a means for displaying the received viewing history information on a screen. And control means for executing a predetermined process based on the viewing history information when a user operation is performed on the viewing history information displayed on the screen.

  If it is said structure, the viewing-and-listening history preserve | saved in another broadcast receiving apparatus can be utilized as needed, without performing the copy process (save).

  According to the present invention, there is an effect that viewing history information accumulated in a certain receiving device can be used in other receiving devices.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 8. Here, a case where digital terrestrial broadcasting is received is illustrated. Further, FIG. 1 shows a portable broadcast receiving apparatus 30, but a fixed or in-vehicle broadcast receiving apparatus has a similar configuration. In digital terrestrial broadcasting, a transmission method called OFDM (Orthogonal Frequency Division Multiplexing) is used, and it is assumed that a portable or in-vehicle broadcast receiving apparatus is used. For this reason, it is considered to perform hierarchical transmission using a plurality of different transmission path encodings as well as broadcasting with a single transmission path encoding. In this hierarchical transmission, for example, a maximum of three hierarchies are used, and there are a strong hierarchy, a middle hierarchy, and a weak hierarchy in order from the lowest required C / N ratio. Strong hierarchy broadcasts and intermediate hierarchy broadcasts are performed for portable and in-vehicle broadcast receivers.

  In FIG. 1, an antenna 1 receives a digital broadcast signal sent from a terrestrial broadcast station.

  The tuner 2 extracts a signal of a specific frequency from the high frequency digital modulation signal including video / audio data. Further, the tuner 2 includes a demodulation circuit, a deinterleave circuit, an error correction circuit, and the like, thereby demodulating the selected digital modulation signal and outputting a transport stream.

  The demultiplexer (DEMUX) 3 separates the transport stream into, for example, an MPEG (Moving Picture Experts Group) video stream, an audio stream, and PSI / SI (Program Specific Information / Service Information). The demultiplexer 3 supplies the video stream and the audio stream to the AV decoder 4, and supplies program guide data (program name, program start time, program content information, program genre information, etc.) included in the PSI / SI to the CPU 13. The data broadcast data is supplied to the BML browser 20. As described above, a plurality of channels are multiplexed in the transport stream, and processing for selecting an arbitrary channel from among these is performed in the transport stream from the PSI / SI. Thus, it becomes possible by taking out data such as which packet ID is multiplexed.

  The AV decoder 4 includes a video decoder that decodes a video stream and an audio decoder that decodes an audio stream. The video decoder decodes the input variable length code to obtain a quantization coefficient and a motion vector, and performs inverse DCT conversion, motion compensation control based on the motion vector, and the like. The audio decoder decodes the input encoded signal to generate audio data. The video data is output to the video processing circuit 5 via the scaler / OSD circuit 12, and the audio data is output to the audio processing circuit 6.

  The video processing circuit 5 receives the video data that has passed through the scaler / OSD circuit 12, performs D / A conversion, and converts it into, for example, a composite video signal. The audio processing circuit 6 receives the audio data output from the decoder 4 and performs D / A conversion to generate, for example, a right (R) sound analog signal and a left (L) sound analog signal.

  The liquid crystal display panel 17 is driven by the video output circuit 7 and the speaker 16 is driven by the audio output circuit.

  The scaler / OSD circuit 12 is a circuit that generates video data based on character information and color information instructed to be output from the browser 20 and the CPU 13. The scaler / OSD circuit 12 displays EPG (Electronic Program Guide) based on program information. Data broadcast display, menu screen display, viewing history display, etc. can be performed.

  The operation pad 10 is an operation unit for sending a command to the broadcast receiving apparatus 30. For example, each key is arranged as shown in FIG. When a key provided on the operation pad 10 is operated, a signal indicating a command corresponding to the key is given to the CPU 13.

  The infrared communication unit 21 performs communication in accordance with a predetermined infrared communication standard, and transmits the viewing history information received from the CPU 13 via the interface 22 to another broadcast receiving device, or transmitted from another broadcast receiving device. Receive incoming viewing history information. Here, as shown in FIG. 4, it is assumed that portable broadcast receiving device 30 transfers viewing history information to fixed type broadcast receiving device 50. The fixed type broadcast receiving apparatus 50 is provided with an infrared receiver for the remote control transmitter 52 (see FIG. 3), and viewing history information is received using this infrared receiver. When another broadcast receiving apparatus is a portable or in-vehicle broadcast receiving apparatus that does not include an infrared receiver for a remote control transmitter, communication is performed according to an infrared communication standard other than that for the remote control transmitter. Of course, it is not limited to such infrared communication, but may be wireless LAN or wired communication. In addition, a removable type is assumed as a vehicle-mounted broadcast receiving apparatus.

  A memory (eg, RAM, ROM, EEPROM, flash memory, etc.) 14 stores guide information for displaying an EPG screen, program viewing history information, and the like. The viewing history information includes viewing date / time information, number of viewings, channel number, program name, genre information, and the like. The program name, genre information, etc. in these information are from SI of the program (transport stream) being viewed by the user. Extracted. The memory 14 stores the transmission standards (code information) of the remote control transmitters of each company, and further stores information indicating which transmission standard is selected.

  The CPU 13 performs overall control in the portable broadcast receiving device 30, but as a process according to the present invention, as described below, executes transmission / reception processing of viewing history information. The fixed broadcast receiving apparatus 50 includes a CPU 51 (not shown), and the processing on the fixed broadcast receiving apparatus 50 side will be described as the CPU 51.

  When a key on the operation pad 10 in the portable broadcast receiving device 30 is operated, operation information corresponding to the operated key is input to the CPU 13. For example, when the menu key of the operation pad 10 is operated, the CPU 13 displays a menu screen using the OSD function. FIG. 5 shows an example of a main menu screen.

  The user uses the up and down arrow keys to move the cursor to the item “user setting” and presses the enter key. When the CPU 13 detects pressing of the enter key while the “user setting” item is selected, the CPU 13 displays three items “channel setting”, “region setting”, and “information transfer device registration”. When the user selects “information transfer device registration” again with the up and down arrow keys and presses the enter key, the CPU 13 displays the information transfer device registration screen shown in FIG. The user moves the cursor to the manufacturer notation portion of the broadcast receiving apparatus 50 to which information is to be transferred using the up / down / left / right arrow keys, and presses the enter key. Here, it is assumed that “Company A” is selected and the enter key is pressed.

  As described above, when “A company” is selected and the enter key is pressed, the CPU 13 displays a selection screen indicating the model number of each remote control transmitter in the A company as shown in FIG. . If the remote control transmitter 52 in the fixed broadcast receiving apparatus 50 is “receiver_1”, for example, the user moves the cursor to the item “receiver_1” using the up / down / left / right arrow keys and presses the enter key. The CPU 13 stores in the memory 14 that “receiver_1” has been selected as the infrared signal transmission standard.

  When the transfer key of the operation pad 10 is operated, the CPU 13 reads the viewing history information from the memory 14 and performs processing for transmitting the viewing history information in accordance with the above-described standard (code) of “receiver_1” (FIG. 4).

  The fixed broadcast receiving device 50 is always in a state where it can receive an infrared signal, and when viewing history information transmitted from the portable broadcast receiving device 30 is received, the viewing history information is stored (stored) in a memory. When the saving is completed, the CPU 51 uses the OSD function to display a message such as “received viewing history information” on the screen as shown in FIG. 8, for example.

  At this time, on the fixed broadcast receiving device 50 side, the viewing history information accumulated by itself and the viewing history information transferred from the portable broadcast receiving device 30 are in a coexisting state. The CPU 51 of the fixed broadcast receiving device 50 performs processing for merging both viewing history information, for example, processing such as adding the number of viewings for a viewing history that overlaps with the viewing history of the own device. In this case, when a list of 10 frequently watched programs is listed and a list screen is generated as a favorite program best ten, the viewing history in the portable broadcast receiving device 30 is reflected. In addition, it is assumed that the user views the broadcast with the portable broadcast receiving device 30 during the daytime and receives the broadcast with the fixed broadcast receiving device 50 from evening to midnight. In this case, when the user turns on the fixed broadcast receiving device 50 in the daytime and requests the list presentation optimal for the current time zone, the viewing history information of the portable broadcast receiving device 30 can be presented. As described above, it is possible to accurately grasp the user's preference of the program by merging both viewing history information. Further, since the user's preference of the program can be grasped more accurately, a program table, a genre search, a program reservation, and the like that collect only the programs that match the user's preference can be performed.

  In the above example, the fixed broadcast receiving apparatus 50 stores (accumulates) the viewing history information transferred from the portable broadcast receiving apparatus 30 in the memory and makes it own, but the present invention is not limited to this. For example, the fixed broadcast receiving device 50 and the portable broadcast receiving device 30 are configured to perform bidirectional communication. For example, the operation pad 10 or the remote control transmitter 52 is provided with a key labeled “Shared”. When the shared key of the remote control transmitter 52 is operated, the fixed broadcast receiving apparatus 50 requests the portable broadcast receiving apparatus 30 to present viewing history information using the bidirectional communication function. Then, the fixed broadcast receiving apparatus 50 displays the viewing history information transmitted from the portable broadcast receiving apparatus 30 on the screen. In this screen, buttons such as “register”, “view”, and “view reservation” are provided. The user views the screen, selects a desired program item, and performs an operation on one of the buttons “Register”, “View”, and “View reservation”. When the “registration” button is operated for the selected program, the CPU 51 registers the history of the program in the memory 14, and when the “view” button is operated, the CPU 51 needs a tuner or the like. Processing is executed, and when the “viewing reservation” button is operated, processing necessary for viewing reservation is executed. In addition, when viewing is actually performed by such processing, viewing history is registered. The sharing described above is a form in which a viewing history stored in another broadcast receiving apparatus is used as needed without performing copy processing (storing).

  Since the transfer or sharing process described above is performed by operating one key such as a transfer key or a shared key, the operability is excellent. Of course, the processing is not limited to such a single key operation. For example, a transfer button or a share button may be displayed on the menu screen, and the above processing may be performed when these buttons are operated. Further, if the above transfer function is used, for example, it is possible to transfer the viewing history from the old broadcast receiving device to the newly purchased broadcast receiving device, and the viewing history is accumulated from the beginning in the new broadcast receiving device. There is no need to go. The same can be said for additional purchases and repairs.

  A viewing history of a program in data broadcasting may be included. The viewing history information in the data broadcast may include a channel number of the data broadcast, a URI (Uniform Resource Identifier), a title, a broadcasting station name, viewing time information, and the like. Further, instead of using all viewing programs as the viewing history, only programs that have been viewed for a predetermined time or more may be registered in the viewing history.
