FIXED INTRA RUN-LEVEL MODE FOR CAVLC IN HEVC
First Claim
1. An electronic device, comprising:
- a processor;
memory in electronic communication with the processor;
instructions stored in the memory, the instructions being executable to;
obtain a run-lev pair;
determine whether to process the run-lev pair in a fixed intra run-level mode;
determine a first cn value for the run-lev pair according to the fixed intra run-level mode if it is determined to process the run-lev pair in the fixed intra run-level mode;
determine a second cn value for the run-lev pair if it is determined not to process the run-lev pair in the fixed intra run-level mode; and
run-level code video data using one of the first and second cn values.

Abstract
An electronic device configured for fixed intra run-level mode is described. The electronic device includes a processor and instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a symbol, e.g. a run-lev pair. The electronic device determines whether a fixed intra run-level mode condition is met. If the condition is met, the electronic device uses fixed intra run-level mode to determine a ‘cn’ value for the symbol. If the condition is not met, the electronic device does not use the fixed intra run-level mode to determine the ‘cn’ value for the symbol. The electronic device run-level codes at least a portion of video data based on the determined ‘cn’ value.

16. An electronic device configured for selective run-level coding (SRLC), comprising:
-
a processor; memory in electronic communication with the processor; instructions stored in the memory, the instructions being executable to; obtain a block of transformed and quantized coefficients (TQCs); determine whether to skip run-level coding; level code any remaining TQCs if it is determined to skip run-level coding; run-level code one or more TQCs if it is determined not to skip run-level coding; and level code any remaining TQCs if it is determined not to skip run-level coding; wherein the instructions are further executable to; if run-level coding is not skipped, obtain a run-lev pair of the block of TQCs; determine whether to process the run-lev pair in a fixed intra run-level mode; determine a first cn value for the run-lev pair according to the fixed intra run-level mode if it is determined to process the run-lev pair in the fixed intra run-level mode; determine a second cn value for the run-lev pair if it is determined not to process the run-lev pair in the fixed intra run-level mode; and run-level code video data using one of the first and second cn values. - View Dependent Claims (17)

18. A method, comprising:
-
obtaining a bit stream; recovering an input value from the bit stream; determining whether to process the recovered input value in a fixed intra run-level mode; determining a first symbol for the recovered input value according to the fixed intra run-level mode if it is determined to process the recovered input value in the fixed intra run-level mode; determining a second symbol for the recovered input value if it is determined not to process the recovered input value in the fixed intra run-level mode; and recovering video data using one of the first and second symbols. - View Dependent Claims (19, 20)
