  • SDR bit depth enhancement via codeword range amplification in a codec with inverse display management
    Patent number: 10834407
    Abstract: Novel methods and systems for encoding standard dynamic range video to improve the final quality after converting standard dynamic range video into enhanced dynamic range video are disclosed. A dual layer codec structure that amplifies certain codeword ranges can be used to send enhanced information to the decoder in order to achieve an enhanced (higher bit depth) image signal. The enhanced standard dynamic range signal can then be up-converted to enhanced dynamic range video without banding artifacts in the areas corresponding to those certain codeword ranges.

  • HEVC with complexity control based on dynamic CTU depth range adjustment
    Patent number: 10834384
    Abstract: A High Efficiency Video Coding (HEVC) system that advantageously controls coding complexity at the coding tree unit (CTU) level. Complexity control is performed by adjusting a depth (or depth range) for CTUs in one or more video sequences in a video stream. To adjust CTU depth, complexity estimation and mapping is first performed to determine complexity requirements for one or more CTUs in a video frame or across frames. In doing so, a statistical complexity estimation model is utilized to yield significantly higher accuracy than other HEVC systems that operate under an assumption that each CTU consumes the same amount of encoding complexity. Complexity allocation is then utilized to ensure that each CTU is provided an optimum complexity. A probability-based CTU depth range adjustment process is utilized to select an appropriate depth range for each CTU.

  • Image processing apparatus, image processing method, and non-transitory computer-readable storage medium
    Patent number: 10834421
    Abstract: Encoding information associated with encoding is acquired for each of a plurality of blocks that are obtained by recursively dividing an image region by quadtree spatial splitting. The encoding information of a target block and sub-blocks that belong to the target block if the image region is divided into units of the sub-blocks that are each smaller than the block are stored in a memory in association with each other. Encoding information that is associated with an adjacent sub-block that is adjacent to a first block among the sub-blocks that belong to a second block that is adjacent to the first block in the image region is acquired from the memory. Then, an encoding process is performed using this acquired encoding information and encoding information of the first block.

  • Synchronizing video signals using cached key frames
    Patent number: 10805615
    Abstract: A technique for synchronizing video receivers with a video stream already in progress includes caching a key frame in a transport protocol component of a video communication system and providing the key frame on demand to any receiver attempting to join the stream and/or to rejoin the stream after an error, such as a dropped packet. Once a receiver obtains the key frame, the receiver requests that the source of the video stream issue a new sync-point frame, where the sync-point frame depends on the key frame but on no other frame for its content. The receiver may then proceed to display rendered video beginning with the sync-point frame.
