Embodiment Construction

[0017] Digital video is used for a variety of purposes including, for example, remote business meetings via videoconferencing, high-definition video entertainment, video advertising, and the sharing of user-generated video. Image and video compression can improve the efficiency of data transmission and storage of digital video. Compression techniques can be used to reduce the amount of information to be transmitted or stored. Internet-based multimedia services, such as streaming video sites, can rely on good compression techniques to improve service quality while controlling bandwidth and cost of content delivery.

[0018] Compression schemes associated with encoding video streams may include dividing each picture into blocks and generating a digital video output bitstream using one or more techniques to limit the information included in the output. The received bitstream can be decoded to recreate the block and source image from the limited information. Encoding a video str...

Abstract

The present invention relates to intelligent rearrangement in recursive block partitioning for advanced intra prediction in video coding. Video data streams can be encoded and decoded using inter-frame or intra-frame prediction. The blocks of the frame may be processed based on the depth from the lowest layer sub-block to the highest layer large block, and are divided into blocks to be inter-predicted, blocks with sub-blocks to be inter-predicted, and blocks to be intra-predicted of sub-blocks, and the group of blocks to be intra-predicted. Blocks to be inter-predicted are coded first, blocks having sub-blocks to be inter-predicted and intra-predicted are coded second, and blocks to be intra-predicted are coded last. Since more pixel data is available for intra prediction for some blocks, the availability of data from inter prediction blocks can improve the performance of intra prediction relative to processing blocks in scan order.

Description

technical field [0001] The present invention relates to intelligent rearrangement in recursive block partitioning for advanced intra prediction in video coding. Background technique [0002] Digital video can be used for a variety of applications including, for example, video conferencing, high-definition video entertainment, video advertising, or the sharing of user-generated video. A digital video stream can represent video using a sequence of frames or still images. Each frame may include a number of blocks, which in turn may contain information describing the color, brightness, or value of other properties of the pixel. Digital video streams can contain large amounts of data and consume significant computing or communication resources of a computing device for processing, transmitting, or storing the video data. Various methods have been proposed to reduce the amount of data in a video stream, including compression and other encoding techniques. Contents of the inven...
