摘要： A method of operating a multi-processor video encoder by determining a target size corresponding to a preferred number of bits to be used when creating an encoded version of a picture in a group of sequential pictures making up a video sequence. The method includes the steps of calculating a first degree of fullness of a coded picture buffer at a first time, operating on the first degree of fullness to return an estimated second degree of fullness of the coded picture buffer at a second time, and operating on the second degree of fullness to return an initial target sized for the picture. The first time corresponds to the most recent time an accurate degree of fullness of the coded picture buffer can be calculated and the second time occurs after the first time.

摘要： A rate and delivery time multiplexing for bandwidth optimization algorithm has an allocation portion and a transrating portion. The allocation portion determines how many bits are available for each group of pictures in each program stream that is to be inserted into an outgoing MPEG Transport Stream (MTS). Based upon the allocated bits the transrating portion, when necessary, further compresses the program streams either in the compressed domain when rate reduction is minimal or in the pixel domain when rate reduction is significant. The result is the ability to transmit more video program streams over a given fixed bandwidth pipe for a given level of acceptable picture degradation.

摘要： A constant bit rate single program encoded transport stream is demultiplexed from a statistically multiplexed MPEG transport stream by separating a variable bit rate program from the multiplexed MPEG transport stream, loading the sequence of pictures that form the variable bit rate program into a smoothing buffer at a rate that does not exceed a desired constant bit rate and transferring the picture from the smoothing buffer at times indicated by decode time stamps associated with the pictures respectively. If a picture of the sequence becomes available no later than a specified amount of time prior to the picture's decode time stamp, then that picture is loaded into the smoothing buffer commencing the specified amount of time prior to the time indicated by the picture's decode time stamp. If a picture of the sequence becomes available later than the specified amount of time prior to the picture's decode time stamp, then that picture is loaded into the smoothing buffer as soon as possible.

摘要： A method of dual-pass rate control video encoding and an encoder are disclosed. Uncompressed input video is received with a video encoder. First pass encoding is performed, and a second pass encoding is performed with the video encoder at a delay relative to the first pass. The first pass encoding detects scene changes within the input video, assigns macroblocks to a pre-determined number of activity classes, and determines a complexity of each picture within the sequence of pictures. Information from the first pass encoding concerning the scene changes, the activity classes, and the complexity are used for rate control determined in second pass encoding for producing and outputting a bit stream of compressed video. During at least one of the first pass and second pass encoding, boundaries of at least some of the GOPs are adjusted to be aligned with the scene changes.
