Abstract:
1. A method of encoding a picture (n) in a sequence of pictures (1 to n) using an encoder, said method comprising the steps of: assigning, by said encoder, a pre-decoder buffer removal time to said picture; constraining, by said encoder, an initial arrival time of said picture into said pre-decoder buffer by selecting, for said picture, a number of bits, wherein said time-equivalent of said number of bits is no greater than a difference based on said pre-decoder buffer removal time of said picture and said initial arrival time of said picture into a pre-decoder buffer; compressing, by said encoder, said picture to generate said number of bits; transmitting, by said encoder, said picture to said pre-decoder buffer in compliance with said initial arrival time, wherein said initial arrival time of said picture into said pre-decoder buffer is in accordance with: where t is a sum of removal delays of said sequence of pictures (1 to n).
