EXTENSION DATA HANDLING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18329739 titled 'EXTENSION DATA HANDLING

Simplified Explanation

Explanation of the abstract: The patent application describes a method for adding an extension field to the slice headers of encoded representations. The length of this extension field is indicated by a length indicator. By parsing this indicator, a decoder can determine which values of the extension field to ignore during decoding. This allows for the addition of the extension field without causing issues for legacy decoders.

  • A length indicator associated with an encoded representation of a slice is parsed.
  • The length indicator indicates the length of an extension field in the slice header.
  • The decoder can ignore certain values of the extension field based on the length indicator.
  • This enables the addition of an extension field to slice headers without affecting legacy decoders.

Potential applications of this technology:

  • Video encoding and decoding systems
  • Multimedia streaming platforms
  • Video conferencing software
  • Video compression algorithms

Problems solved by this technology:

  • Compatibility issues between legacy decoders and encoded representations with added extension fields
  • Limitations in the ability to add new features or information to encoded representations without breaking compatibility

Benefits of this technology:

  • Allows for the addition of extension fields to encoded representations without affecting legacy decoders
  • Enables the incorporation of new features or information into encoded representations without sacrificing compatibility
  • Provides flexibility for future enhancements and improvements in video encoding and decoding systems.


Original Abstract Submitted

A length indicator associated with an encoded representation of a slice is parsed. The length indicator is indicative of a length of an extension field present in a slice header of the encoded representation. A decoder can then determine to ignore, during decoding of the encoded representation, any value of the extension field in the slice header where these values are identified based on the length indicator. As a consequence, an extension field can be added to slice headers and still enable legacy decoders to correctly decode the encoded representations.
