Title:
REGION-OF-INTEREST BASED VIDEO CODING USING HINTS, IN PARTICULAR FOR VIDEO GAMES
Document Type and Number:
WIPO Patent Application WO/2015/157135
Kind Code:
A3
Abstract:
Embodiments are directed to encoding frames in response to supplemental encoding instructions, to providing encoding information for frames and to compiling software code that includes encoding hints. In one embodiment, in response to accessing frame information associated with a frame, a computer system interprets the frame information as being a supplemental encoding instruction for encoding a specified portion of the frame. The computer system then encodes the frame so that the specified portion of the frame is encoded in accordance with the supplemental encoding instruction.
