A method for generating a compressed digital video bitstream, comprising the steps of receiving a first subsequence representing a video signal, receiving a second sub-sequence representing an alpha signal, and generating the compressed digital video bitstream in response to the first sub-sequence and the second sub-sequence. The compressed digital video bitstream (i) includes information from said video signal and information from said alpha signal and (ii) conforms to a defined transmission standard.
