Title: Parallel processing pipeline considerations for video data with portions designated for special treatment
Inventor: HUANG JIONG
IPC: H04N7/08
Filed: 2019-12-14
Abstract: 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.

Abstract: A processing unit performs alignment of a short read (SR) against a reference genome sequence. The processing unit determines whether the SR is aligned. If the SR is not aligned, the processing unit receives the next SR and processes the next SR by repeating. If the SR is aligned, in response to the determination that the SR is aligned with the reference genome sequence at a first position in the reference genome sequence, the processing unit generates a new SR metadata entry corresponding to the SR. The processing unit finds a linked list in a SR metadata collection. The first position of the linked list in the SR metadata collection corresponds to the first position of the reference genome sequence where the SR is aligned. The processing unit performs duplicate marking based on the SR and the linked list.
