<P>PROBLEM TO BE SOLVED: To provide a digital broadcast receiver capable of outputting a received digital broadcast signal so that there will not be deviation in the output time. <P>SOLUTION: An output control part 110 receives a scene detection signal output from a scene detecting part of each hierarchy, acquires a time at which a scene change is detected from a clocking part 113 and stores the time in each detection table of each hierarchy. The output control part 110 calculates the deviation in the output time of a video signal and a sound signal between respective hierarchies in a digital broadcast receiver 100, on the basis of data of the scene detection table of each hierarchy. The output control part 110 adjusts the buffer storage amount of a buffer part of each hierarchy so as that it corresponds to the deviation in output time and controls timing for outputting the video signal and the sound signal to a decoding part of each hierarchy so that there will not be deviation the in output time. <P>COPYRIGHT: (C)2008,JPO&INPIT |
