PARALLEL PROCESSING PIPELINE CONSIDERATIONS FOR VIDEO DATA WITH PORTIONS DESIGNATED FOR SPECIAL TREATMENT

摘要

As video goes to higher levels of definition, the rate at which video data needs to be processed increases. To be able to process video data more rapidly, a video source can use parallel processing, where pixels are grouped into sets of N pixels for N processing pipelines. The video data may include designated sections that require special treatment. For example, when supporting High-bandwidth Digital Content Protection (HDCP) in an HDMI (High-Definition Multimedia Interface) signal, the blanking intervals of a frame of video data may have a specified range of pixels designated as non-compressible for subsequent Repeat Count (RC) encoding. To avoid a set of pixels grouped together for parallel processing including pixels both within and outside of the designated portion, the video source can augment the designated portion with a number of preceding and/or following adjacent pixels.
