Parallel Coding with Overlapped Tiles

摘要

A video encoding system uses overlapped tiles. The system reduces or eliminates cross-core data communication when tiles are processed in parallel on multi-core platforms. The overlapped tiles are designed to simplify the multi-core codec design by avoiding cross core data communication while still maintaining good video quality along tile boundaries.

主权项

1. A device comprising,
interface circuitry configured to receive an input comprising a first tile and a second tile, where the first tile includes a first region overlapping with a portion of the second tile, the first tile different than the second tile; and coding circuitry in data communication with the interface circuitry, the coding circuitry configured to:
determine border pixels located within the first region;after determination of the border pixels, remove first pixels other than the border pixels from the first region of the first tile; andcombine the first and second tiles.
