A method is provided for decoding an encoded video stream on a processor having a plurality of processing cores includes receiving and examining a video stream to identify any macroscopic constructs present therein that support parallel processing. Decoding of the video stream is divided into a plurality of decoding functions. The plurality of decoding functions is scheduled for decoding the video stream in a dynamic manner based on availability of any macroscopic constructs that have been identified and then based on a number of bytes used to encode each block into which each picture of the video stream is partitioned. Each of the decoding functions is dispatched to the plurality of processing cores in accordance with the scheduling.

A method is provided for determining a context-index when performing Context-based Adaptive Binary Arithmetic Coding (CABAC) for video compression or decompression includes initializing to an initialized value each of a plurality of context-indexes of chosen syntax elements associated with a given block (e.g., a macroblock). The context-index of dependent neighboring blocks of the given block is evaluated. The dependent neighboring blocks are blocks that have a context-index that depends on coding of a current bin position. The context-index of the dependent neighboring blocks is updated if and only if their context-index changes from the initialized values.

A method and system is provided for encoding video data according to target decoding device complexity. One embodiment is evidenced by a method of encoding video data for decoding on a target decoding device having parallel processing, comprising: receiving uncoded video data, computing a relationship between each of a plurality of encoding parameters and target decoding device decoding costs, selecting encoding parameters to minimize encoding costs, wherein the encoding costs include the target decoding device decoding costs, and encoding the uncoded video data according to the selected encoding parameters.

A method for minimizing searching time for a transport format selection in a CDMA communication system including an RLC layer and an MAC layer. The RLC layer entity contains a plurality of logical channels and transmits input data to the MAC layer through a specific logical channel from among the logical channels. The MAC layer contains a plurality of transport channels and transmits the input data to a physical layer through a specific transport channel from among the transport channels. Transport formats are generated for the transport channels, and classified according to sizes of data that can be transmitted by corresponding transport channels. An indicator is provided to each of the transport formats classified according to data size, and a plurality of subset tables are generated. When the data is input to the MAC layer, after the subset tables are generated, a subset table having a same size as the data input to the MAC layer is detected, and a transport format corresponding to a specific indicator is selected.
