CUSTOM DATA INDICATING NOMINAL RANGE OF SAMPLES OF MEDIA CONTENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18384059 titled 'CUSTOM DATA INDICATING NOMINAL RANGE OF SAMPLES OF MEDIA CONTENT

Simplified Explanation

The abstract describes a media processing tool that adds custom data to a media bitstream or container to indicate the nominal range of samples in the media content. This custom data is not defined in the codec or container format, allowing for support of full or limited range media content while maintaining backward compatibility.

• The media processing tool adds custom data to media content to indicate the nominal range of samples.
• The custom data is not defined in the codec or container format, allowing for flexibility in supporting different ranges.
• A rendering engine performs color conversion operations based on the media content type indicated by the custom data.
• This innovation extends codec or container formats to support full or limited range media content while preserving color fidelity and compatibility.

Potential Applications

This technology can be applied in video editing software, streaming services, media players, and digital cameras to enhance color accuracy and fidelity in media content.

Problems Solved

1. Maintaining color fidelity in media content with different nominal ranges. 2. Ensuring backward compatibility while supporting new media content types.

Benefits

1. Improved color accuracy and fidelity in media playback. 2. Flexibility in supporting different nominal ranges of media content. 3. Enhanced user experience with better color representation.

Potential Commercial Applications

"Enhancing Color Fidelity in Media Processing for Improved User Experience"

Possible Prior Art

There may be prior art related to color conversion operations in media processing tools or techniques for extending codec formats to support new media content types.

How does this technology impact file sizes of media content?

The abstract does not mention any impact on file sizes of media content. It would be interesting to know if adding custom data affects the overall size of media files and if there are any optimizations in place to mitigate any increase.

Are there any limitations to the types of media content that can be supported by this technology?

The abstract focuses on nominal range of samples in media content, but it would be helpful to understand if there are any restrictions on the types of media content that can benefit from this innovation.

Original Abstract Submitted

A media processing tool adds custom data to an elementary media bitstream or media container. The custom data indicates nominal range of samples of media content, but the meaning of the custom data is not defined in the codec format or media container format. For example, the custom data indicates the nominal range is full range or limited range. For playback, a media processing tool parses the custom data and determines an indication of media content type. A rendering engine performs color conversion operations whose logic changes based at least in part on the media content type. In this way, a codec format or media container format can in effect be extended to support full nominal range media content as well as limited nominal range media content, and hence preserve full or correct color fidelity, while maintaining backward compatibility and conformance with the codec format or media container format.
