A method for encoding a video stream divided in macroblocks using an encoding scheme, the video stream comprising a transparency level channel, said method comprising:
- classifying said macroblocks into inner macroblocks, for which a transparency value provided by said transparency information channel is substantially uniform, and transition macroblocks, for which a transparency value provided by said transparency level channel is not substantially uniform;
- determining a statistic of said transparency value for each one of said inner macroblocks; and
- configuring a respective parameter of said encoding scheme for each one of said inner macroblocks in function of its respective statistic. |
