STORING MISALIGNED REFERENCE PIXEL TILES - A simplified explanation of the abstract

This abstract first appeared for US patent application 17838081 titled 'STORING MISALIGNED REFERENCE PIXEL TILES

Simplified Explanation

The abstract describes a method for caching misaligned pixel tiles in a video coding system. Here are the key points:

  • The method involves determining a first codec region and a first region of a frame.
  • It checks whether pixels of a first version of a pixel tile were stored in a cache while coding blocks from a second codec region.
  • Depending on whether the pixels were stored in the cache, it decides whether to read the first version of the pixel tile from the cache or retrieve a second version of the pixel tile from a memory device.
  • The second version of the pixel tile includes pixels from the first codec region that are not present in the first version.
  • Finally, a block is coded based on the version of the pixel tile read from the cache or retrieved from the memory device.

Potential applications of this technology:

  • Video coding and compression systems
  • Real-time video streaming
  • Video editing and post-production

Problems solved by this technology:

  • Efficient caching of misaligned pixel tiles
  • Reducing the need for frequent retrieval of pixel tiles from memory
  • Improving video coding and compression performance

Benefits of this technology:

  • Faster video coding and decoding processes
  • Reduced memory access and bandwidth requirements
  • Improved video quality and compression efficiency


Original Abstract Submitted

Systems and techniques are provided for caching misaligned pixel tiles. A method includes determining a first codec region including a first region of a frame; determining whether pixels of a first version of a pixel tile were stored in a cache while coding blocks from a second codec region, the pixel tile corresponding to a location within the frame; based on whether the pixels were stored in the cache, determining whether to read the first version of the pixel tile from the cache or retrieve a second version of the pixel tile from a memory device, the second version of the pixel tile including pixels from the first codec region that are not in the first version of the pixel tile; and coding a block based on the first version of the pixel tile read from the cache or second version of the pixel tile retrieved from the memory device.
