Device and Method for Processing Ultra High Definition (UHD) Video Data Using High Efficiency Video Coding (HEVC) Universal Decoder

摘要

The present invention discloses a device and method for processing video data using HEVC universal decoder. The HEVC universal decoder is designed to address the parallel execution issues and bandwidth issues when there is a decoded data transfer among the processors. The decoder is designed to achieve better core utilization with reduced memory bandwidth. The decoder is designed to work in two partitions to obtain the decoded YUV pictures output from a bit-stream. The invention provides for reduction in the number of processors used in the first partition of the HEVC universal decoder without affecting the decoding rate of the bit-streams. In second partition, decoding of one data-frame is carried out simultaneously by four processors. Both the partitions complete their respective decoding processes in equal amount of time.

1. A device for processing Ultra High Definition (UHD) video data using High Efficiency Video Coding (HEVC) decoder, the device comprises of:
a. one or more processors arranged into at-least two partitions, wherein the two partitions are configured to operate the HEVC decoder using into two phases for decoding process; b. the first phase of HEVC decoder operates for the first partition and the second phase of HEVC decoder operates for the second partition; c. a plurality of video frames received from the overhead information is decoded in the first partition using the first phase of HEVC decoder, wherein the first partition uses single processor to decode the single video frame using the first phase of HEVC decoder; and d. the second partition receives the decoded video frames from the first partition, wherein the second partition decodes and stores the decoded video frames using the second phase of HEVC decoder, wherein the second partition uses the multiple processors to decode and store the decoded single video frame using the second phase of HEVC decoder.
