Patent ID: 8285106

Claim:
An information processing apparatus for processing input video data in a processing unit and input audio data in a processing unit different from the processing unit for the input video data in size, comprising: ending time information calculating means for calculating ending time information of the processing unit of the input video data and ending time information of the processing unit of the input audio data from the input video data in the processing unit and the input audio data in the processing unit; first gap amount information calculating means for, when the input video data in the processing unit and the input audio data in the processing unit are spliced to previous processing units directly, calculating, for each of the processing units, first gap amount information indicating a gap amount between the input video data in the processing unit and the input audio data in the processing unit for synchronizing the input video data in the processing unit and the input audio data in the processing unit; second gap amount information calculating means for calculating, for each of the processing units, second gap amount information indicating a gap amount between ending time information of the video data in the previous processing unit and the input audio data in the processing unit for synchronizing the input audio data in the processing unit and the input video data in the processing unit; and mute data inserting means for, when the second gap amount is larger than the first gap amount, inserting mute information indicating a mute between the previous audio data and the input audio data for each of the processing unit.
