Bitrate reduction method by requantization |
摘要 |
The method is characterized in that:
- if the current macroblock was coded according to the "skipped macroblock" mode and if at least one corrected coefficient block of said macroblock has coefficients non-null or greater than a predefined threshold, the coding mode of the macroblock is modified (50) into a mode other than "skipped macroblock" and the data of the data stream is modified or added (50) to specify this mode and the value of the coefficients. |
