<P>PROBLEM TO BE SOLVED: To perform seamless broadcast reception by a single reception system. <P>SOLUTION: A digital broadcast receiver 1 includes: a reception system 103 which reproduces a video stream and an audio stream of the program of a selected channel being currently set from a broadcast wave received by a single tuner; and a communication unit 104 which transmits a switching request to carried-in device 2 when the reception level of the tuner becomes low in the reception system 103. The carried-in device 2 transmits a video stream and an audio stream representing a predetermined program to the digital broadcast receiver 1 in response to the switching request from the communication unit 104. In the digital broadcast receiver 1, the communication unit 104 transfers the video stream and audio stream from the carried-in device 2 to the reception system 103. The reception system 103 switches the video stream and audio stream being reproduced so far, to the video stream and audio stream from the communication unit 104, by means of predetermined information. <P>COPYRIGHT: (C)2010,JPO&INPIT |
