Abstract:
1. An information processing apparatus, comprising: a separating unit operable to separate an input multiplexed stream into a first stream comprised of video stream information and a second stream comprised of stream information other than the video stream information; a decoding unit operable to decode the first stream and to determine an input bit rate of the first stream; an analyzing unit operable to determine an input bit rate of the second stream; a setting unit operable to set a total bit rate of an output multiplexed stream; a controller operable to control coding conditions for reencoding the decoded first stream, the coding conditions including an output bit rate of the first stream that is determined on the basis of output bit rate of the second stream and the total bit rate of the output multiplexed stream, the output bit rate of the second stream being set to be identical to the input bit rate of the second stream; a coding unit operable to reencode the first stream under the coding conditions; and a multiplexing unit operable to multiplex the reencoded first stream and the second stream to produce the output multiplexed stream.
