Abstract: According to one embodiment, a video-audio playback apparatus includes: a compressed-audio-data decoding portion configured to decode compressed audio data of a program and thereby to generate audio data; an audio data processing portion configured to compare a sound volume of the audio data for an arbitrarily-determined period with a threshold; and a compressed-video-data decoding portion configured to perform first decoding processing on compressed video data for the arbitrarily-determined period synchronized with the audio data for the arbitrarily-determined period when the sound volume of the audio data for the arbitrarily-determined period is equal to or lower than the threshold, the first decoding processing being according to the compressed video data.

Abstract: An audio player includes: a buffer unit that temporary stores sampling values contained in a second-half frame of each of a plurality of frames received in time series, the frames containing audio data; a detecting unit that detects a defect in the frames; an inverted-frame generating unit that generates a first-half inverted frame containing first-half complementarity samples obtained by arranging the sampling values of the second-half frame of a normal frame in a reverse order of the time series, the normal frame being received immediately before the defect is detected; a non-inverted frame generating unit that generates a second-half non-inverted frame containing second-half complementarity samples obtained by arranging the sampling values of the second-half frame of the normal frame in the time series; and an output unit that outputs the normal frame, the first-half inverted frame, and the second-half non-inverted frame, in this order.
