Title:
PARALLEL ENCODING OF VIDEO FRAMES WITHOUT FILTERING DEPENDENCY
Document Type and Number:
WIPO Patent Application WO/2023/029045
Kind Code:
A1
Abstract:
Disclosed are techniques for compressing data of an image using multiple processing cores. The techniques include obtaining, using a first (second, etc. ) processing core, a first (second, etc. ) plurality of reconstructed blocks approximating source pixels of a first (second, etc. ) portion of an image and filtering, using the first processing core, the first plurality of reconstructed blocks. The filtering includes enabling application of one or more filters to a first plurality of regions that include pixels of the first plurality of reconstructed blocks but not pixels of the second plurality of reconstructed blocks. The filtering further includes disabling application of the one or more filters to a second plurality of regions that include pixels of the first plurality of reconstructed blocks and pixels of the second plurality of reconstructed blocks.
