The entropy coding of each vertical section is performed in parallel such that each encoder unit performs entropy coding on its respective vertical section. De-blocking is performed on the two or more vertical sections in parallel on a row-by-row basis.

摘要： Mode searching and early termination of a video picture may include determining the cost value of a simple intra-mode prediction of the video picture; determining the cost value of an inter-mode prediction of the video picture; determining a threshold value based on a given quantization parameter (QP); comparing the cost value of the simple intra-mode prediction to the sum of the cost value of the inter-mode prediction and the threshold value; and performing a mode-prediction of the video picture in accordance with the result obtained. Fast compression of variable length symbols may include receiving a variable length symbol with one or more tokens; combining the one or more tokens in the variable length symbol to form a token combination; and determining a bit representation of the token combination in correspondence to a probability threshold associated with the token combination.

A first decoding subtask is performed on all macroblocks in the coded picture or a section thereof. After performing the first decoding subtask on all macroblocks in the coded picture or a section thereof, a second decoding subtask is performed on all the macroblocks in the coded picture or section thereof. One or more of the first and second tasks includes examining a slice or macroblock within the coded picture to determine if there are any errors, and if an error is present, handling the error.

摘要： Prediction of and recovery from display buffer underflow are described. A first time delay for displaying a first group of one or more frames of a video picture stream located in an output frame buffer is calculated. A second time delay for displaying a second group of one or more frames in the picture stream is calculated. The second group directly follows the first group in the output buffer and is currently decoded by a decoder, but not yet deposited into the output frame buffer. A third time delay for decoding a third group of one or more frames in the picture stream is calculated. The third group directly follows the second group and is not yet decoded by the decoder. The decoder switches to or remains in a fast decoding mode if the sum of the first and second time delays is less than the third time delay.

摘要： Parallel coding of digital pictures is described. A digital picture is divided into two or more vertical sections. Two or more corresponding Stage 1 encoder units can perform a first stage of entropy coding on the two or more vertical sections on a row-by-row basis. The entropy coding of the vertical sections can be performed in parallel such that each Stage 1 encoder unit performs entropy coding on its respective vertical section and returns a partially coded Stage 1 output to a Stage 2 encoder unit. Each partially coded Stage 1 output includes a representation of data for a corresponding vertical section that has been compressed by a compression factor greater than 1. The Stage 2 encoder unit can generate a final coded bitstream from the partially encoded Stage 1 output as a Stage 2 output.
