Abstract:
1. An information processing apparatus for processing video data in a processing unit and audio data in a processing unit different from the processing unit of the video data in size, comprising: detecting means for detecting a synchronization gap amount for each of the processing units of the audio data and the video data; first gap amount computing means for, when the audio data and the video data in the processing units are spliced to previous processing units, computing a first gap amount indicating a gap amount for synchronizing the audio data and the video data based on the synchronization gap amount detected by the detecting means; first creating means for creating a header for each of the processing units including the first gap amount; and second creating means for creating a block of the processing units of the audio data and the video data and adding the header created by the first creating means thereto; output meats for outputting the block including the audio data and the video data to which the header is added by the second creating means; and determination means for determining whether or not a number of channels of the audio data is smaller than a maximum number of processable channels, wherein the output means increases the number of channels such that the number of channels can be equal to the maximum number and adds and outputs mute data to the increased channels When the determination means determines that the number of channels of the audio data is smaller than the maximum number.
