Sony patents faster video decoding using split computer tasks
Sony has been granted a patent for a method to decode video data more efficiently by splitting the work between two computer processors. One processor handles the raw data conversion while the other simultaneously interprets the structure of that data, allowing them to work in parallel without waiting for each other.
In the filing’s own words
A method, system, and computer readable medium for improved decoding CABAC encoded media are described. A decoded binary string is output using two or more previously decoded elements at an end state for a decoding loop and on a first processing thread. A syntax of the decoded binary string is parsed on a second processing thread and a decoded symbol from the parsed syntax is generated on the second processing thread.
What exactly they claim (claim 1)
1. A method for decoding CABAC encoded media, comprising: outputting a decoded binary string from two or more previously decoded elements at an end state for a decoding loop on a first processing thread; parsing a syntax of the decoded binary string on a second processing thread in parallel to the first processing thread, and the first processing thread decoding the binary string independent of the second processing thread; and generating a decoded symbol based on the parsed syntax on the second processing thread; wherein the end state includes an entry indicating a symbol type, and parsing the syntax includes selecting a code block for the decoded binary string based on the entry.
