STANDARD DYNAMIC RANGE (SDR) / HYBRID LOG-GAMMA (HLG) WITH HIGH DYNAMIC RANGE (HDR) 10+ - A simplified explanation of the abstract

This abstract first appeared for US patent application 17491413 titled 'STANDARD DYNAMIC RANGE (SDR) / HYBRID LOG-GAMMA (HLG) WITH HIGH DYNAMIC RANGE (HDR) 10+

Simplified Explanation

The patent application describes a computer-implemented method for processing high dynamic range (HDR) media content. Here are the key points:

  • The method involves accessing HDR media content and performing statistical analysis on each incremental portion of the content to determine statistical information.
  • Metadata is generated for each incremental portion of the HDR media content, providing additional information about the content.
  • A standard dynamic range (SDR) version of the content is derived using the HDR metadata, allowing for compatibility with devices that do not support HDR.
  • The metadata and SDR version of the HDR media content are transmitted to a storage service and then received at a display device.
  • The SDR version is converted back to HDR with a dynamic range bounded based on the metadata, ensuring optimal viewing experience.

Potential applications of this technology:

  • Media streaming platforms can use this method to provide HDR content to users with HDR-capable devices while also delivering SDR versions for non-HDR devices.
  • Content creators can utilize this method to efficiently distribute HDR media content to a wider audience, including those without HDR-compatible devices.
  • Display device manufacturers can incorporate this technology to enhance the viewing experience by converting SDR content to HDR within the device.

Problems solved by this technology:

  • The method solves the problem of limited compatibility with HDR media content by providing an SDR version that can be viewed on non-HDR devices.
  • It addresses the challenge of transmitting and storing HDR content efficiently by utilizing metadata and converting to SDR when necessary.

Benefits of this technology:

  • Users with HDR-capable devices can enjoy the enhanced visual experience of HDR media content.
  • Content providers can reach a larger audience by delivering both HDR and SDR versions of their content.
  • The method allows for efficient transmission and storage of HDR media content by utilizing metadata and converting to SDR when needed.


Original Abstract Submitted

A computer-implemented method includes accessing a high dynamic range (HDR) media content item. Statistical analysis is performed to determine statistical information associated with the HDR media content item at each incremental portion of the HDR media content item. Metadata for each incremental portion of the HDR media content item is generated. A standard dynamic range (SDR) version of the content is derived using the HDR metadata. The metadata and an SDR version of the HDR media content item is transmitted to a storage service. The metadata and the SDR version are caused to be received at a display device. The SDR version is converted to HDR with a dynamic range bounded based on the metadata.
