Abstract
A mechanism for processing video data is disclosed. A type for a value taken by a region identifier (ID) in a region identifier (ID) type field (region_id_type) is determined. The type for the value taken by the region ID is coded in the region ID type field using four or less bits. A conversion between the visual media data and a media data file is performed based on the type for the value taken by the region ID in the region ID type field.
Claims20
A method for processing visual media data, comprising:
- determining a type for a value taken by a region identifier based on a first syntax element, wherein the first syntax element is coded using four or less bits;
- and
- performing a conversion between the visual media data and a media data file based on the type for the value taken by the region identifier.
An apparatus for processing video data comprising:
- a processor;
- and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
- determine a type for a value taken by a region identifier based on a first syntax element, wherein the first syntax element is coded using four or less bits;
- and
- perform a conversion between a visual media data and a media data file based on the type for the value taken by the region identifier.
A non-transitory computer-readable storage medium storing instructions that cause a processor to:
- determine a type for a value taken by a region identifier based on a first syntax element, wherein the first syntax element is coded using four or less bits;
- and
- perform a conversion between a visual media data and a media data file based on the type for the value taken by the region identifier.
A method for storing a media data file of media data, comprising:
- determining a type for a value taken by a region identifier based on a first syntax element, wherein the first syntax element is coded using four or less bits;
- generating the media data file based on the type for the value taken by the region identifier;
- and
- storing the media data file in a non-transitory computer-readable recording medium.
