Abstract
Encoding or decoding syntax information associated with video information can involve identifying a coding context associated with a syntax element of a current coding unit of the video information, wherein the identifying occurs without using a syntax element of a neighboring block, and encoding or decoding the syntax element of the current coding unit based on the coding context.
Claims20
A method for encoding syntax information associated with video information comprising:
- selecting a coding context associated with a syntax element of a current coding unit of the video information, wherein the coding context is selected among two coding contexts and the selecting occurs without using a syntax element of a neighboring block;
- and
- encoding the syntax element of the current coding unit based on the coding context, wherein the syntax element of the current coding unit indicates use of a video encoding mode and comprises an adaptive motion vector resolution mode syntax.
A method for decoding syntax information associated with video information comprising:
- selecting a coding context associated with a syntax element of a current coding unit of the video information, wherein the coding context is selected among two coding contexts and the selecting occurs without using a syntax element of a neighboring block;
- and
- decoding the syntax element of the current coding unit based on the coding context wherein the syntax element of the current coding unit indicates use of a video encoding mode or video decoding mode and comprises an adaptive motion vector resolution mode syntax.
An apparatus for encoding syntax information associated with video information comprising:
- one or more processors configured to:
- select a coding context associated with a syntax element of a current coding unit without using a syntax element of a neighboring block, wherein the coding context is selected among two coding contexts;
- and
- encode the syntax element of the current coding unit based on the coding context wherein the syntax element of the current coding unit indicates use of a video encoding mode and comprises an adaptive motion vector resolution mode syntax.
An apparatus for decoding syntax information associated with video information comprising:
- one or more processors configured to:
- select a coding context associated with a syntax element of a current coding unit without using a syntax element of a neighboring block, wherein the coding context is selected among two coding contexts;
- and
- decode the syntax element of the current coding unit based on the coding context wherein the syntax element of the current coding unit indicates use of a video decoding mode and comprises an adaptive motion vector resolution mode syntax.
