シンタクス要素を得るステップを含み;
前記シンタクス要素は、レイヤ識別子がレイヤ識別子シンタクス要素値と等しい非イントラランダムアクセスポイント(IRAP)ピクチャがレイヤ間予測のための参照ピクチャとして使用されるか否かを示し、
レイヤ間参照ピクチャセットのピクチャを「長期参照に使用される」ものとしてマーキングするか否かを判断するステップを含み;
前記シンタクス要素が時間識別子の値よりも大きい場合に、前記レイヤ間参照ピクチャセットの前記ピクチャが「長期参照に使用される」ものとしてマーキングされ、
前記シンタクス要素が前記時間識別子の前記値よりも大きくない場合に、前記レイヤ間参照ピクチャセットの前記ピクチャが「長期参照に使用される」ものとしてマーキングされない、方法。 A video decoding method comprising:
Wherein the step of obtaining the syntax elements;
The syntax element indicates whether a non-intra random access point (IRAP) picture whose layer identifier is equal to the layer identifier syntax element value is used as a reference picture for inter-layer prediction;
The picture of the reference picture set between the layers comprising the step of determining whether to mark as "used for long-term reference";
If the syntax element is greater than the value of the temporal identifier, the picture of the inter-layer reference picture set is marked as “used for long-term reference”;
The method, wherein the picture of the inter-layer reference picture set is not marked as “used for long-term reference” if the syntax element is not greater than the value of the temporal identifier .
プロセッサと、 A processor;
前記プロセッサと電子通信するメモリと、を備え、 A memory in electronic communication with the processor,
前記メモリにストアされている命令は、シンタクス要素を得るように実行可能であり、 Instructions stored in the memory are executable to obtain syntax elements;
前記シンタクス要素は、レイヤ識別子がレイヤ識別子シンタクス要素値と等しい非イントラランダムアクセスポイント(IRAP)ピクチャがレイヤ間予測のための参照ピクチャとして使用されるか否かを示し、 The syntax element indicates whether a non-intra random access point (IRAP) picture whose layer identifier is equal to the layer identifier syntax element value is used as a reference picture for inter-layer prediction;
前記命令は、レイヤ間参照ピクチャセットのピクチャを「長期参照に使用される」ものとしてマーキングするか否かを判断するように実行可能であり、 The instructions are executable to determine whether to mark a picture of an inter-layer reference picture set as being “used for long-term reference”;
前記シンタクス要素が時間識別子の値よりも大きい場合に、前記レイヤ間参照ピクチャセットの前記ピクチャが「長期参照に使用される」ものとしてマーキングされ、 If the syntax element is greater than the value of the temporal identifier, the picture of the inter-layer reference picture set is marked as “used for long-term reference”;
前記シンタクス要素が前記時間識別子の前記値よりも大きくない場合に、前記レイヤ間参照ピクチャセットの前記ピクチャが「長期参照に使用される」ものとしてマーキングされない、電子デバイス。 The electronic device, wherein the picture of the inter-layer reference picture set is not marked as “used for long-term reference” if the syntax element is not greater than the value of the temporal identifier.
