Abstract
A system and method are provided including a deblocker processor that reads a first data load for a first processing block from a buffer. The deblocker processor holds 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 and receives a second data load for a second processing block from the buffer. In response to the second data load including a valid value for a second quantization parameter, the deblocker processor processes the first processing block based on the second quantization parameter.
