Abstract:
Example apparatus to encode video disclosed herein include an encoder to perform an intra search first stage based on source pixels of a source video frame to determine first intra candidates to predict a block of the source video frame. In disclosed examples, the encoder is also to perform an intra search second stage based on reconstructed pixels of neighboring blocks associated with the first intra candidates to determine a second intra candidate. In disclosed examples, the encoder is further to encode the block of the source video frame based on the second intra candidate.

US Patent:
20190261001, Aug 22, 2019
Filed:
May 1, 2019
Appl. No.:
16/400882
Inventors:
- Santa Clara CA, US
Dmitry E. Ryzhov - Mountain View CA, US
Lidong Xu - Beijing, CN
Satya N. Yedidi - Roseville CA, US
Wenhao Zhang - Beijing, CN
Assignee:
INTEL CORPORATION - Santa Clara CA
International Classification:
H04N 19/147
H04N 19/176
H04N 19/105
H04N 19/124
H04N 19/567
Abstract:
A system for video encoding is described herein. The system includes a processor to execute a multi-pass palette search and mapping on a video frame to generate palette candidates. The processor is to execute an intra block copy prediction on the video frame to generate intra-block-copy candidates. The processor is to also calculate a rate distortion optimization (RDO) cost for a set of generated residuals, the palette candidates, and the intra-block-copy candidates. The processor is to further also execute a final mode decision based on a comparison of the rate distortion optimization (RDO) costs.

Abstract:
An apparatus of video encoding is described herein. The apparatus includes an encoder and a hardware bit packing unit. The encoder includes a fixed function hierarchical motion estimation search unit, fixed function integer motion estimation search units, and a fixed function check and refinement unit. The check and refinement unit is to generate residuals using nested loops based on at least one spatial domain prediction and at least one frequency domain prediction and perform a final mode decision based on rate distortion optimization (RDO) costs associated with the generated residuals. The hardware bit packing unit is to pack bits as coded according to the final mode decision into a data format.

Abstract:
Techniques related to video coding with sample adaptive offset coding are discussed.

In some examples, such techniques may also include setting the sample adaptive offset coding flag based on a coding structure associated with coding the group of pictures.
