    • 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.
    • 描述了一种配置用于固定的内部运行级模式的电子设备。 电子设备包括处理器和存储在与处理器电子通信的存储器中的指令。 电子设备获得一个符号,例如 一对跑步对。 电子设备确定是否满足固定的内部运行级模式条件。 如果满足条件,电子设备使用固定的内部运行级别模式来确定符号的“cn”值。 如果不满足条件,则电子设备不使用固定的内部运行级别模式来确定符号的“cn”值。 电子设备运行级基于所确定的“cn”值对视频数据的至少一部分进行编码。
