  The update control unit 106 controls data update of the storage unit 107, and the storage unit 107 is a unit that holds data even when the digital broadcast receiver 101 is turned off. As an example of the storage unit 107, for example, a non-volatile memory that can hold data even when the power is OFF can be cited.

  The time management unit 108 is a unit that notifies the program information acquisition management unit 103 of current time information (program information acquisition time information) in response to a current time acquisition request from the program information acquisition management unit 103.

  The communication unit 109 is a unit that performs two-way communication with the data broadcasting operation management center, the program information storage server 151, and the like through a telephone line. The communication means used by the communication unit 109 may be a means other than a telephone line as long as it is different from the communication means used when the receiving unit 102 receives broadcast radio waves. For example, other examples of communication means used by the communication unit 109 include ISDN lines, broadband using FTTH (FIBER TO THE HOME), ADSL (ASYMMETRIC DIGITAL SUBSCRIBER LINE), UWD (ULTRA WIDE BAND), and the like. It is done.

  The power management unit 110 supplies power to a necessary part according to the power ON / OFF state of the digital broadcast receiver 101, and at the minimum time necessary for acquiring the program information of the digital broadcast receiver 101 at a predetermined time. It is a unit that supplies electricity only to a limited part and automatically activates each unit that has supplied electricity.

  The channel selection management unit 111 instructs the receiving station 102 to select the broadcasting station, and the demultiplexing unit 112 separates the video / audio signal and program information multiplexed on the digital broadcast signal demodulated by the receiving unit 102, and The audio decoding unit 113 decodes the encoded video / audio signal, and the display control unit 114 switches or synthesizes the decoded video / audio signal and display of program information (program guide / program content), etc. Output to the TV monitor 150.

  In the case of normal program viewing, when the power of the digital broadcast receiver 101 is turned on by a user operation, the power management unit 110 supplies power to all parts of the digital broadcast receiver 101 and the digital broadcast receiver 101 Activate all parts.

  The receiving unit 102 receives a digital broadcast wave of a broadcasting station selected from an antenna connected to the outside, and outputs the demodulated digital signal to the demultiplexing unit 112.

  The demultiplexing unit 112 separates the digital signal into a video / audio signal and program information. The video / audio signal separated by the demultiplexing unit 112 is decoded by the video / audio decoding unit 113 and output to the television monitor 150 under the control of the display control unit 114.

  The program information separated by the demultiplexing unit 112 is added with time information acquired from the time management unit 108 by the program information acquisition management unit 103 (acquisition time information acquired program information). The program information acquisition management unit 103 stores the acquisition time information at which the program information is acquired in the storage unit 105 together with the program information.

  The acquisition time information stored in the storage unit 105 is an example of identification information indicating whether acquisition of program information has been completed. As current time information, “year / month / day / hour / minute”, “year / month / day / hour / minute / second”, etc. may be stored. As another example of the identification information indicating whether or not the acquisition of program information has been completed, a method of setting a flag when the acquisition of program information is completed may be used.

  When the user finishes viewing the program and the power of the digital broadcast receiver 101 is turned off by the user operation, the power management unit 110 transfers to the video / audio decoding unit 113 and the display control unit 114 of the digital broadcast receiver 101. Stop supplying the power.

  The update control unit 106 compares the program information and acquisition time information stored in the storage unit 105 with the program information and acquisition time information stored in the storage unit 107 on a segment basis for each broadcasting station. Since the storage unit 107 stores a plurality of program information and a plurality of acquisition time information acquired before the previous time, the update control unit 106 stores a plurality of program information and a plurality of acquisition times stored in the storage unit 105. The information is compared with the plurality of program information stored in the storage unit 107 and the plurality of acquisition time information, and when it is determined that the new program information is currently stored in the storage unit 105, the information is stored in the storage unit 105. The program information and the acquisition time information in the storage unit 107 are updated or added from the new program information and the acquisition time information.

  When the update control unit 106 finishes writing the added / updated program information in the storage unit 107, the power management unit 110 supplies power to other parts of the digital broadcast receiver 101 other than the power management unit 110. Stop supplying. That is, in the digital broadcast receiver 101 with the outlet connected, only the power management unit 110 is supplied with power when the power is turned off.

  Next, an operation of automatically acquiring program information for each broadcasting station at a predetermined time when the digital broadcast receiver 101 is turned off will be described.

  When the digital broadcast receiver 101 reaches a predetermined time, the power management unit 110 causes a part necessary for acquiring program information (from all parts of the digital broadcast receiver 101, the video / audio decoding unit 113 and the display control unit). The power supply for the portion excluding 114 is started.

  The channel selection management unit 111 instructs the reception unit 102 to sequentially select receivable broadcast stations.

  The receiving unit 102 selects a designated broadcast station and receives a digital broadcast wave.

  Program information acquired from a digital broadcast wave is repeatedly transmitted at a specific cycle, and in each cycle, an event number for identifying a program, a program start time and a program duration (program broadcast time information), a program A plurality of pieces of data such as information on the title and other program attributes and contents are acquired for each segment divided in time-series units. Thus, the program information is acquired for each segment of each divided program information, based on the broadcasting time information of each program information, dividing each program information into one or a plurality of segments according to the broadcasting time.

  When the program information of one cycle of EIT [schedule basic], which is regulated by digital terrestrial broadcasting, is acquired, the program information up to one week ahead can be acquired.

  The program information acquisition management unit 103 adds the acquisition time information acquired from the time management unit 108 to the program information separated by the demultiplexing unit 112 and saves it in the storage unit 105 in the same manner as in the case of normal program viewing by the user. To do. That is, the segment of the divided program information and the acquisition time information are stored in the storage unit 105 for each segment. Here, the acquisition time information is an example of identification information indicating whether or not information acquisition for each segment of each program information has been completed, as described above.

  When the program information acquisition management unit 103 has acquired all the broadcast station program information, the program information acquisition management unit 103 determines that the program information acquisition has been completed, and notifies the power supply management unit 110 of the completion of program information acquisition.

  The subsequent operation of the power management unit 110 is the same as when the program viewing ends and the power of the digital broadcast receiver 101 is turned off by a user operation, and thus the description thereof is omitted here.

  When there is a broadcasting station in which the program information acquisition management unit 103 cannot add / update the program information due to the fact that the digital broadcast wave is stopped during the acquisition of the program information, the determination unit 104 Determining the segment of the broadcast station for which the program information could not be acquired by determining whether or not the acquisition of each segment of the program information has been completed based on the identification information stored in the storage unit 105, and the telephone line The communication unit 109 is instructed to acquire the program information from the program information storage server 151 in segments.

  When the digital broadcast receiver 101 is turned on by a user operation while the program information is being acquired, the power management unit 110 supplies power to the video / audio decoding unit 113 and the display control unit 114.

  Upon receiving the power ON notification from the power management unit 110, the program information acquisition management unit 103 immediately stops acquiring the program information by the digital broadcast wave from the broadcasting station, and turns off the power to the channel selection management unit 111. Instruct to select the channel (broadcasting station) you were watching before.

  The determination unit 104 identifies the segment of the broadcasting station related to the program information that could not be acquired when the acquisition of the program information by the digital broadcast wave was stopped in this way, and from the program information storage server 151 via the telephone line. The communication unit 109 is instructed to acquire the program information in units of segments.

  The communication unit 109 connects a telephone line to the program information storage server 151, acquires the program information that could not be acquired for each segment, and notifies the program information acquisition management unit 103.

  When the communication unit 109 acquires all program information instructed by the determination unit 104 in units of segments, the communication unit 109 disconnects the telephone line to the program information storage server 151.

  The acquisition time information acquired from the time management unit 108 is added to the segment unit program information notified to the program information acquisition management unit 103 and stored in the storage unit 105 as in the case of normal program viewing. As described above, the acquisition time information is an example of identification information for identifying whether or not a segment of program information has been acquired.

  The program information acquisition management unit 103 determines that the program information acquisition has been completed when the program information is being automatically acquired and the digital broadcast receiver 101 does not need to be turned on. Notify completion.

  The subsequent operation of the power management unit 110 is the same as that when the program viewing ends and the power of the digital broadcast receiver 101 is turned off by a user operation.

  An example of program information recorded in the storage unit 105 and the storage unit 107 is shown in FIG. In FIG. 2, program information 201 is managed in units of program broadcast time (segment 203) for each program broadcast date 202. In addition, since the program information 201 is acquired for each broadcasting station 204, when specifying a segment that needs to be added / updated, whether the program information 201 should be added / updated for each broadcasting station 204 and for each segment 203. Need to be identified. For example, in FIG. 2, the unacquired segment for broadcast station 1 is identified as broadcast station 204 being B1 (broadcast station 1) and segment 203 being S3 (9-12 o'clock).

  In addition, the segment should just divide 1 day into the predetermined time slot | zone, and does not need to be divided | segmented every 3 hours. For example, a long time zone may be one segment during the night, and a short time zone may be one segment during the golden time.

  Next, the program information acquisition operation of the digital broadcast receiver 101 will be described with reference to the flowchart of FIG.

  First, when the AC power of the digital broadcast receiver 101 is turned on (S1), the digital broadcast receiver 101 waits for a user operation or event occurrence (S2). The user operation indicates that the digital broadcast receiver 101 is set and the channel selection operation is performed using a remote control key or the like, and the event occurrence indicates, for example, automatic update of program information or a reserved recording operation.

  When the AC power of the digital broadcast receiver 101 is turned on, the power management unit 110 determines that the power is turned off (S3), and the user watches the channel before the channel selection management unit 111 turns off the AC power. The selected broadcast station is selected and the program is viewed (S4). In the case of channel selection by user operation, the channel selection management unit 111 determines that the operation is user operation (S3), selects a broadcast station designated by the user, and starts program viewing (S4).

  If it is determined by the user operation that the power is turned on (S5), the program information is updated.

  Similarly, when it is determined that the program information is automatically updated when the power is turned off (S6), the program information is updated.

  In the program information update process, first, the program information acquisition management unit 103 determines whether there is a broadcast station that needs to be updated (S7), and if it remains, it is turned on from power OFF (S8: If the power is not turned on by a user operation during acquisition of program information, a broadcast station that needs to acquire program information is selected (S9), and the communication unit 109 segments unacquired program information of the selected broadcast station. Acquired in units, and the acquired program information is stored in the storage unit 105 (S10).

  The processes from (S7) to (S10) are repeated until the selection of all the broadcast stations that need to update the program information is completed or the power is turned on by a user operation.

  Next, the determination unit 104 determines whether or not acquisition of program information of a broadcast station that can be viewed has been completed (S11). If not, the communication unit 109 obtains necessary program information from the program information storage server 151. Obtain (S12). The program information acquired from the program information storage server 151 is stored in the storage unit 105 (S13).

  Next, the power management unit 110 determines whether or not an operation from power OFF to ON has been performed by a user operation (S14). If the power is ON, program viewing (S4) is performed. When the power is not turned on, only the added / updated program information is written from the storage unit 105 to the storage unit 107 (S15), and the power is turned off.

  That is, when the power is not turned on, the update control unit 106 needs to update or add by comparing the program information stored in the storage unit 105 with the acquisition time information, the program information stored in the storage unit 107, and the acquisition time information. Program information is specified, and a plurality of program information and a plurality of acquisition time information stored in the storage unit 107 are updated from the specified program information and acquisition time information stored in the storage unit 105.

  In the above embodiment, the determination unit 104 has explained that the determination of acquiring program information from the program information storage server 151 via the telephone line is performed when automatic acquisition of program information is completed or interrupted. You may implement at another timing.

  For example, when the digital broadcast receiver 101 is always used with the power on, the program information automatic acquisition operation at the predetermined time in the above embodiment is not executed at all. In such a case, a segment of a broadcasting station that needs to acquire program information at a predetermined time may be specified from the program information acquisition date and time, and the communication unit 109 may be instructed.

  In addition, as a criterion for selecting a segment of a broadcasting station that needs to acquire program information in the determination unit 104, acquisition of program information is performed by a flag indicating that the segment update date and time has passed for a predetermined period or more. It is good also as conditions which determine whether it is required.

  Regarding the update of program information, it is conceivable to update the program information from the beginning by connecting to the program information storage server 151 via a communication line, but at least communication is required compared with free program information that can be received by broadcast waves. Since it costs a line connection, it is assumed that the program information from the broadcast wave is updated.

  As described above, a digital broadcast having a function of receiving a digital broadcast wave including program information, accumulating program information separated from the broadcast wave, and displaying the program information as a program guide or performing a reservation operation such as recording. In the receiver 101, the program information acquisition management unit 103 that stores and controls program information obtained from broadcast waves, and the acquisition completion / uncompleted determination in units (segments) for acquiring program information for each broadcasting station that acquires program information And a communication unit 109 that acquires program information of a segment determined to be incomplete by the determination unit 104 from a server (program information storage server 151) that stores program information via a communication line. The broadcast receiver 101 has been described.

  In addition, when the power switch of the digital broadcast receiver 101 is OFF at a predetermined time, a power management unit 110 that automatically activates only a minimum part necessary for acquiring program information of the digital broadcast receiver 101 is provided.
