摘要： Selecting a coding mode for coding video data by measuring a distortion sensitivity threshold for a pixel block, calculating a distortion threshold representative of the maximum distortion that may be effectively masked by the brightness and texture of the pixel block, estimating the distortion induced by coding the pixel block according to skip mode and coding the source pixel block with a predictive coding technique if the estimated distortion value exceeds the distortion threshold. The distortion sensitivity threshold may include, for example, a brightness value or a texture value. The contrast between the pixel block and the surrounding pixel blocks may also be considered such that if the contrast exceeds a contrast threshold calculated based on the measurement of brightness and texture, the source pixel block may be coded with a predictive coding technique even if the estimated distortion value does not exceed the distortion threshold.

摘要： A system and method for switching between multiple encoders or decoders may be implemented to quickly and seamlessly transfer coding operations between two encoders. Before switching from a first encoder to a second encoder, the second encoder is initialized and updated with a copy of the necessary information from the first encoder. Similarly when switching from a first decoder to a second decoder, the second decoder is initialized and the necessary information from the first decoder is passed to the second decoder. A controller may monitor the system to identify a condition that would trigger an encoder switch and identify the encoder that best suits the system conditions. A shared memory unit accessible by either encoder may store the initialization information. A shared decode unit accessible by either encoder may transmit decoded frames between encoders.

摘要： Embodiments of the present invention provide techniques for efficiently coding/decoding video data during circumstances where a decoder only requires or utilizes a portion of coded frames. A coder may exchange signaling with a decoder to identify unused areas of frames and prediction modes for the unused areas. An input frame may be parsed into a used area and an unused area based on the exchanged signaling. If motion vectors of the input frame are not limited to the used areas of the reference frames, the unused area of the input frame may be coded using low complexity. If the motion vectors of the input frame are limited to the used areas of the reference frames, the pixel blocks in the unused area of the input frame may not be coded, or the unused area of the input frame may be filled with gray, white, or black pixel blocks.
