Hardware-friendly sample adaptive offset (sao) and adaptive loop filter (alf) for video coding

A device for decoding video data, the device comprising:

• a memory configured to store video data;
• and
• one or more processors configured to:
• determine filter information for a region of a picture of the video data;
• for a largest coding unit (LCU) of the region, determine a size for a current unit based on a location of the LCU within the picture, wherein the size for the current unit is different than a size of the LCU;
• based on the determined filter information, determine a filter for the current unit of the region;
• and
• filter the current unit with the determined filter.

An apparatus for coding video data, the apparatus comprising:

• means for determining filter information for a region of a picture of video data;
• means for determining a size for a current unit based on a location of a largest coding unit (LCU) of the region within the picture, wherein the size for the current unit is different than a size of the LCU;
• means for determining a filter for the current unit of the region based on the determined filter information;
• and
• means for filtering the current unit with the determined filter.

A computer readable storage medium storing instructions that when executed cause one or more processors to:

• determine filter information for a region of a picture of the video data;
• for a largest coding unit (LCU) of the region, determine a size for a current unit based on a location of the LCU within the picture, wherein the size for the current unit is different than a size of the LCU;
• based on the determined filter information, determine a filter for the current unit of the region;
• and
• filter the current unit with the determined filter.
