METHOD AND APPARATUS FOR INTRA-PREDICTION CODING OF VIDEO DATA - A simplified explanation of the abstract

This abstract first appeared for US patent application 18093533 titled 'METHOD AND APPARATUS FOR INTRA-PREDICTION CODING OF VIDEO DATA

Simplified Explanation

The abstract describes a method and apparatus for coding video data using intra-prediction. Intra-prediction is a technique used in video compression to predict the values of pixels within a block based on neighboring pixels.

  • The apparatus includes a decoder that decodes a syntax element indicating the intra-prediction type of a current block of video data.
  • An intra-predictor then generates a prediction block for the current block by selectively performing matrix-based intra-prediction or regular intra-prediction based on the intra-prediction type indicated by the syntax element.

Potential applications of this technology:

  • Video compression: The method and apparatus can be used in video compression algorithms to improve the efficiency of encoding and decoding video data.
  • Video streaming: By reducing the size of video data through efficient intra-prediction coding, this technology can help in streaming high-quality videos over limited bandwidth networks.

Problems solved by this technology:

  • Efficient video compression: Intra-prediction coding helps in reducing the redundancy in video data, resulting in smaller file sizes and improved compression ratios.
  • Improved video quality: By accurately predicting pixel values within a block, this technology can enhance the visual quality of compressed videos.

Benefits of this technology:

  • Higher compression efficiency: By selectively using matrix-based intra-prediction or regular intra-prediction, the method and apparatus can achieve better compression ratios compared to traditional intra-prediction techniques.
  • Reduced bandwidth requirements: Smaller video file sizes enable faster transmission and reduced bandwidth requirements, making it suitable for video streaming applications.
  • Improved video quality: Accurate intra-prediction helps in preserving details and reducing artifacts, resulting in higher visual quality of compressed videos.


Original Abstract Submitted

A method and apparatus for intra-prediction coding of video data are provided. The apparatus includes a decoder that is configured to decode, from a bitstream, a syntax element indicating an intra-prediction type of a current block of the video data, and an intra-predictor that is configured to generate a prediction block for the current block by selectively performing matrix based intra-prediction or regular intra-prediction based on the intra-prediction type of the current block indicated by the syntax element.
