REFERENCE PICTURE SIGNALING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18458256 titled 'REFERENCE PICTURE SIGNALING

Simplified Explanation

The abstract describes a method for decoding an encoded representation of a picture or video stream by retrieving buffer description information from the encoded representation. This buffer description information is used to determine a picture identifier that identifies a reference picture to be used as a decoding reference for the picture. The decoded picture buffer is then updated based on the determined picture identifier. The encoded representation of the picture contains the necessary information for the decoder to identify the reference pictures required for decoding.

  • The method involves decoding an encoded representation of a picture or video stream.
  • Buffer description information is retrieved from the encoded representation.
  • The buffer description information helps determine a picture identifier.
  • The picture identifier identifies a reference picture to be used as a decoding reference for the picture.
  • The decoded picture buffer is updated based on the determined picture identifier.
  • The encoded representation of the picture contains the necessary information for the decoder to identify the reference pictures required for decoding.

Potential Applications

  • Video streaming services
  • Video compression technologies
  • Video playback software

Problems Solved

  • Efficient decoding of encoded picture or video streams
  • Accurate identification of reference pictures for decoding

Benefits

  • Improved video quality
  • Reduced bandwidth usage
  • Faster decoding process


Original Abstract Submitted

An encoded representation of a picture of a video stream is decoded by retrieving buffer description from the encoded representation. The buffer description information is used to determine at least one picture identifier identifying a respective reference picture as decoding reference for the picture. A decoded picture buffer is updated based on the determined picture identifier. The encoded representation of the picture itself comprises the information needed by a decoder to identify the reference pictures required to decode the encoded representation.
