摘要： A dynamic AC prediction technique is implemented in a data partition mode which automatically disables AC prediction for encoding the current macroblock in the next packet when packet overflow occurs. Otherwise, when there is no overflow, AC prediction remains enabled to maintain compression efficiency. More particularly, in the preferred embodiment, a determination is first made whether a macroblock causes a packet overflow if it is encoded in the current packet. If so, a new packet is initiated into which the macroblock is encoded without AC prediction as the first macroblock. Otherwise, the macroblock with AC prediction remains in the current packet and a new macroblock is encoded.

摘要： The present invention facilitates efficient and effective detection of pixel alteration. The number and configuration of pixels in a block partition can be flexibly changed. The filter inputs in the multi-protocol filter can be flexibly changed to meet the deblocking requirement in the target video compression standard. In one embodiment, the deblock engine includes an input interface, a neighbor buffer, a current data buffer; and a multi-protocol filter. The input interface receives reconstructed data. The neighbor buffer temporarily stores neighbor information. The current data buffer receives the reconstructed data and the neighbor information. The multi-protocol filter filters information selected from the reconstructed data and neighbor information.

摘要： The present invention facilitates efficient and effective detection of pixel alteration. In one embodiment a pixel alteration analysis system includes a difference summing multiple engine component and a control component. The difference summing multiple engine component determines the sum of differences between pixel values in a plurality of pixels. The control component determines an indication of motion based upon said relationship of said pixels in said plurality of pixels. In one exemplary implementation, the difference in values corresponds to a relationship between values of pixels in a block of pixels at different frames. The number and configuration of pixels in a block partition can be flexibly changed.
