Abstract
An apparatus includes a video data decoder and a coded picture buffer to buffer successive portions of an input video data and provide a portion to the video data decoder for decoding. The video data decoder is responsive to parameter data associated with the input video data. The parameter data indicates, for a given input video data, an encoding level selected from a plurality of encoding levels. Each level defines at least a maximum luminance picture size, a minimum compression ratio, and a maximum value of the coded picture buffer size. For each encoding level of the plurality of encoding levels, the maximum value of the coded picture buffer size is greater than or equal to the number of bits required to represent a picture at the maximum luminance picture size when encoded according to the minimum compression ratio.
