Abstract
Method for encoding a video stream having a transparency information channel in view of a predetermined target bit rate for said transparency information channel, comprising: tentatively applying a first encoding () to said transparency information channel, said first encoding () comprising lossless vector graphics encoding; if said first encoding results in an encoded bitrate within said predetermined target bitrate (), selecting said first encoding () to produce an encoded version of said transparency information channel; otherwise, tentatively applying a second encoding () to said transparency information channel, said second encoding () comprising a mathematical representation encoding scheme; if said second encoding results in an encoded bitrate within said predetermined target bitrate (), selecting said second encoding () to produce an encoded version of said transparency information channel; otherwise, selecting a third encoding () to produce an encoded version of said transparency information channel, said third encoding comprising MPEG-based encoding.
