Method for neighboring block data management of advanced video decoder

A method comprising:

• decoding a current macroblock (MB) comprising one or more blocks in a media processing device, including:
• calculating the addresses of a plurality of neighboring MBs of the current MB at least in part from a pre-computed table of probable neighboring block locations for all possible current MB and neighboring MB configurations;
• using the addresses to retrieve a property for each neighboring MB;
• determining if any of the neighboring MBs are unavailable based on the property of each neighboring MB;
• retrieving a plurality of indices from the pre-computed table based on whether any of the neighboring MBs are unavailable, the indices identifying one or more neighboring blocks of each of the one or more blocks of the current MB, at least one of the one or more neighboring blocks of at least one of the one or more blocks located in one of the neighboring MBs;
• and
• selecting a neighboring block table based on availability of at least one of the plurality of neighboring MBs;
• retrieving properties of the identified one or more neighboring blocks from the neighboring block table to decode the current MB and decoding the current MB at least in part based on the retrieved properties of the identified one or more neighboring blocks.

An article comprising a non-transitory machine-readable storage medium containing instructions that if executed enable a system to:

• decode a current macroblock (MB) comprising one or more blocks including to
• calculate the addresses of a plurality of neighboring MBs of the current MB at least in part from a pre-computed table of probable neighboring block locations for all possible current MB and neighboring MB configurations;
• use the addresses to retrieve a property for each neighboring MB;
• determine if any of the neighboring MBs are unavailable based on the property of each neighboring MB;
• retrieve a plurality of indices from the pre-computed table based on whether any of the neighboring MBs are unavailable, the indices identifying one or more neighboring blocks of each of the one or more blocks of the current MB, at least one of the one or more neighboring blocks of at least one of the one or more blocks located in one of the neighboring MBs;
• and
• select a neighboring block table based on availability of at least one of the plurality of neighboring MBs;
• retrieve properties of the identified one or more neighboring blocks from the neighboring block table to decode the current MB and decode the current MB at least in part based on the retrieved properties of the identified one or more neighboring blocks.
