摘要： A distributed video encoding system splits an input video into video segments. The video segments are encoded using multiple video encoding nodes. Prior to the process of splitting the sequence into video segments, the video is analyzed to generate a dependency map. Intelligent segmentation is performed using the dependency map so that each video segment includes all the video frames from which other video frames within that segment have been encoded in the input video. For example, picture headers are inspected to determine the temporal distance of the farthest past and future reference frames used for encoding frames of a video.

摘要： A video data decoding device and method. The device has an entropy decoder, and a WPP status control module for selecting an operating status according to a syntax structure of a coding tree unit. The device further has a memory selector for controlling the operating status of a memory. The memory has one buffer memory and two update memories. When the number of columns of a row of coding tree units currently decoded is larger than three, the context data of the coding tree units currently decoded is written into the buffer memory and one of the update memories; and when it is determined that the context data of the coding tree units referred by a first coding tree unit in a next row of coding tree units is available when the next row of coding tree units starts to be parsed, the data in the buffer memory is replicated.

摘要： A method for encoding a video signal includes estimating a space requirement for encoding a tile of a video frame, writing a first value in a first value space of the bitstream, wherein the first value describes a size of a second value space, and defining the second value space in the bitstream, wherein the size of the second value space is based on an estimated space requirement. The method also includes writing encoded content in a content space of the bitstream, determining a size of the content space subsequent to writing encoded content in the content space, and writing a second value in the second value space of the bitstream, wherein the second value describes the size of the content space.
