METHOD, DEVICE, AND COMPUTER PROGRAM FOR IMPROVING RANDOM PICTURE ACCESS IN VIDEO STREAMING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17917168 titled 'METHOD, DEVICE, AND COMPUTER PROGRAM FOR IMPROVING RANDOM PICTURE ACCESS IN VIDEO STREAMING

Simplified Explanation

The abstract describes a method for encapsulating a video bit-stream in a server. The method involves obtaining NAL units (network abstraction layer units) of two pictures, buffering the NAL units of the first picture, and encapsulating the NAL units of the second picture and the buffered NAL units in an encapsulation structure.

  • Obtaining NAL units of a first picture
  • Buffering the obtained NAL units
  • Obtaining NAL units of a second picture
  • Encapsulating the obtained NAL units of the second picture and the buffered NAL units in an encapsulation structure
  • Generating a video bit-stream without processing the encapsulated buffered NAL units

Potential applications of this technology:

  • Video streaming services
  • Video conferencing systems
  • Video surveillance systems

Problems solved by this technology:

  • Efficient encapsulation of video bit-streams
  • Reducing processing requirements for encapsulated video bit-streams

Benefits of this technology:

  • Improved video streaming performance
  • Reduced processing overhead
  • Enhanced video quality and reliability


Original Abstract Submitted

A method for encapsulating a video bit-stream in a server, including obtaining at least one network abstraction layer unit (NAL unit) of a first picture, buffering the at least one obtained NAL unit, obtaining at least one NAL unit of a second picture, the second picture being a random access picture following the first picture, and encapsulating the at least one obtained NAL unit of the second picture and the at least one buffered NAL unit in an encapsulation structure making it possible to generate a video bit-stream without processing the encapsulated at least one buffered NAL unit when processing the encapsulated video bit-stream
