(Embodiment 1)
A portable receiver according to Embodiment 1 of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram showing an example of the hardware configuration of the portable receiver according to the first embodiment of the present invention. 1 includes a key input receiver 102, a CPU (Central Processing Unit) 103, a memory 104, a nonvolatile memory 106, a tuner module 111, a TS decoder 112, and a B-CAS (BS-Conditional Access System) card. 113, a descrambler 114, a video decoder 115, an audio decoder 116, and a battery 117. The memory 104 holds a digital broadcast reception program 105, and the nonvolatile memory 106 holds an EPG storage unit 107, a battery remaining amount statistics storage unit 108, a recording reservation storage unit 109, and a recorded program storage unit 110. Note that the B-CAS card 113 and the descrambler 114 may not be included in the hardware configuration in the case of partial reception or in a country or region where broadcast program copy control is not performed.

  The key input receiving unit 102 receives a user key input, and sends the contents of the key input to the digital broadcast receiving program 105 stored in the memory 104. The CPU 103 executes the digital broadcast reception program. The digital broadcast receiving program 105 receives a reception frequency corresponding to a broadcast station that transmits the broadcast program based on a channel selection request for the broadcast program specified by the user, received from the key input reception unit 102, and the tuner module 111. Set to.

  In addition, when the tuner module 111 cannot receive a TS (Transport Stream) including the broadcast program, the digital broadcast reception program 105 transmits a broadcast of the same genre as the broadcast program from the EPG storage unit 107 in the nonvolatile memory 106. Get a list of programs. The digital broadcast receiving program 105 searches for the broadcast program of the same genre, and then the battery at the time when reception of the broadcast program fails on the next day from the battery remaining amount statistics storage unit 108 in the nonvolatile memory 106. The remaining amount is predicted, and one or more recording reservations for the program of the same genre are set in the recording reservation storage unit 109 in the nonvolatile memory 106 based on the battery remaining amount. The digital broadcast receiving program 105 executes recording based on the recording reservation in the recording reservation storage unit 109 and stores the recorded program in the recorded program storage unit 110 in the nonvolatile memory 106. If the digital broadcast receiving program 105 again fails to receive the broadcast program designated by the user, the digital broadcast receiving program 105 presents the latest recorded program among the recorded programs stored in the recorded program storage unit 110 instead.

  When the tuner module 111 is able to receive a TS including a broadcast program designated by the user through control or processing by the digital broadcast receiving program 105, the tuner module 111 sends the TS to the TS decoder 112, and transmits the TS. When it cannot be received, the digital broadcast receiving program 105 is notified. The TS decoder 112 performs the following processing through control or processing by the digital broadcast reception program 105. First, the TS is acquired from the tuner module 111, and a video PES (Packetized Elementary Stream) and an audio PES constituting the broadcast program are acquired. Here, when copy control is applied to the broadcast program, a decryption key is obtained from the B-CAS card 113, the decryption key is set in the descrambler 114, and the video PES and the audio PES are set. Unscramble the. Thereafter, a video ES (Elementary Stream) and an audio ES are generated from the video PES and the audio PES, and then the video ES is sent to the video decoder 115 and the audio ES is sent to the audio decoder 116.

  The video decoder 115 decodes the video ES under the control or processing of the digital broadcast reception program 105, and outputs the video to the display at the presentation time added to the video PES. The audio decoder 116 decodes the audio ES under the control or processing of the digital broadcast reception program 105, and outputs the audio to the speaker at the presentation time added to the audio PES.

Set to 202. The tuner control unit 202 sets the reception frequency acquired from the receiver control unit 201 in the tuner module 111.

  The TS processing unit 203 cooperates with the TS decoder 112 to acquire the video PES and audio PES constituting the broadcast program from the TS acquired via the tuner module 111 and the tuner control unit 202. Here, when copy control is performed on the broadcast program, the TS processing unit 203 obtains a decryption key from the B-CAS card 113, sets the decryption key in the descrambler 114, and the video PES. And descrambling the audio PES. Then, in cooperation with the TS decoder 112, the video ES and the audio ES are generated from the video PES and the audio PES, and then the video ES and the audio ES are sent to the decode control unit 204. The decoding control unit 204 decodes the video ES and audio ES acquired from the TS processing unit 203 based on the decoding time of each ES, and then the decoding control unit 204 presents video and audio. At time, video is output to the display and audio is output to the speaker.

  The EPG management unit 205 acquires an EPG from the EPG storage unit 107 in response to a request from the receiver control unit 201, and displays a list of broadcast programs of the same genre as the broadcast program designated by the user. To 201. The battery remaining amount statistics management unit 206 acquires the transition of the remaining battery amount from the battery remaining amount statistics storage unit 108 in response to a request from the receiver control unit 201. The receiver control unit 201 predicts the remaining battery level at the same time on the following day based on the acquired transition of the remaining battery level for the time at which reception of the broadcast program has failed. Accordingly, one or a plurality of recording reservations for the same genre program are set in the recording control unit 207. The recording control unit 207 registers the set recording reservation in the recording reservation storage unit 109, executes actual recording based on the registered recording reservation, and stores the recorded program in the recorded program storage unit. Stored in 110.
