1. A system comprising: a deblocker processor operable to: receive a first data load for a first processing block from a buffer; hold the first data load in a storage array in response to the first data load not including a valid value for a first quantization parameter; receive a second data load for a second processing block from the buffer; and in response to the second data load including a valid value for a second quantization parameter, process the first processing block based on the second quantization parameter.
