Abstract
A device for coding video data is configured to code a first syntax element, wherein a value for the first syntax element indicates whether there is at least one non-zero transform coefficient level associated with a first block of video data; determine a context for a second syntax element based on the value for the first syntax element, wherein the second syntax element indicates coding mode information for a second block of video data; and code the second syntax element based on the determined context.
Claims22
A method of coding video data, the method comprising;
- coding a first syntax element, wherein a value for the first syntax element indicates whether there is at least one non-zero transform coefficient level associated with a first block of video data;
- determining a context for a second syntax element based on the value for the first syntax element, wherein the second syntax element indicates coding mode information for a second block of video data;
- and
- coding the second syntax element based on the determined context.
A device for coding video data, the device comprising:
- a memory;
- and
- one or more processors configured to:
- code a first syntax element, wherein a value for the first syntax element indicates whether there is at least one non-zero transform coefficient level associated with a first block of video data;
- determine a context for a second syntax element based on the value for the first syntax element, wherein the second syntax element indicates coding mode information for a second block of video data;
- and
- code the second syntax element based on the determined context.
