Abstract
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.
