20130114684 | ELECTRONIC DEVICES FOR SELECTIVE RUN-LEVEL CODING AND DECODING - An electronic device configured for selective run-level coding (SRLC) 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 block of transformed and quantized coefficients (TQCs). The electronic device also determines whether to skip run-level coding. The electronic device further level codes any remaining TQCs if it is determined to skip run-level coding. The electronic device additionally run-level codes one or more TQCs if it is determined not to skip run-level coding and level codes any remaining TQCs if it is determined not to skip run-level coding. | 05-09-2013 |
20130114687 | FIXED INTRA RUN-LEVEL MODE FOR CAVLC IN HEVC - 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. | 05-09-2013 |
