1. A method comprising: by a deblocker processor: reading a first set of parameters for a first processing block from a buffer; determining if the first set of parameters does not include a valid quantization value for processing the first processing block; storing the first set of parameters including transform coefficients in a storage array on the deblocker processor in response to the first set of parameters not including the valid quantization value for processing the first processing block; operating on the first processing block by at least one of a motion compensation processor, inverse transform processor, and spatial prediction processor based on the first set of parameters stored in the storage array prior to receiving to a valid quantization value corresponding to the first processing block; reading a subsequent set of parameters for subsequent processing blocks from the buffer; and processing the first processing block based on a valid quantization value in the subsequent set of parameters, in response to the subsequent set of parameters including the valid quantization value for processing the first processing block.
