VARIABLE BITRATE VIDEO CODING METHOD AND CORRESPONDING VIDEO CODER |
摘要 |
The variable bitrate coding method according to the invention comprises an iterative process including a first analysis pass and a second prediction pass. The analysis pass allows for a picture coding of a sequence with a constant quantization stepsize (and quality) and the prediction pass allows for a matching of the stepsize to the wanted target bitrate. After some iterations, a last step allows for a finer adjustment of said stepsize with respect to said target bitrate. Application: MPEG-2 encoders for storage media with limited capacity. |
