Hypothetical reference decoder with low start-up delays for compressed image and video
E Viscito, DT Hoang - US Patent 7,532,670, 2009 - Google Patents
In one aspect, a method for encoding pictures is provided. The method is applied to each
picture in a sequence of pictures, and the method comprises the steps of assigning a pre-de
coder buffer removal time to the picture; selecting, for the picture, a number of bits, wherein
the time-equivalent of the number of bits is no greater than a difference based on the pre-
decoder buffer removal time of the picture and an initial arrival time of the picture into a pre-
decoder buffer; and compressing the picture to generate the number of bits. The method …
