Abstract
1. Способ сигнализации для информации о делении сигнала, содержащий этапы, на которых ! назначают количество нижних узлов, равное количеству делений, для нижнего уровня, если узел верхнего уровня представлен посредством идентификатора (ИД) деления; и ! не назначают никакой нижний узел для нижнего уровня, если узел верхнего уровня представлен посредством идентификатора (ИД) неделения, ! причем информация о делении сигнала включает в себя ИД деления и ИД неделения, указывающие наличие или отсутствие деления сигнала в узле уровня. ! 2. Способ по п.1, дополнительно содержащий этапы, на которых ! осуществляют последовательную сигнализацию узлов верхнего уровня; и ! осуществляют последовательную сигнализацию узлов нижнего уровня. ! 3. Способ по п.1, дополнительно содержащий этапы, на которых ! осуществляют сигнализацию нижнего узла нижнего уровня, соответствующего первому узлу верхнего уровня, если первый узел верхнего уровня представлен посредством ИД деления; и ! осуществляют сигнализацию второго узла верхнего уровня, если первый узел верхнего уровня представлен посредством ИД неделения. ! 4. Способ по любому из пп.1-3, в котором распознают глубину из информации о делении сигнала. ! 5. Способ по п.1, дополнительно содержащий этап, на котором ! осуществляют сигнализацию информации о глубине уровня. ! 6. Способ по п.5, в котором информацию о глубине уровня представляют посредством переменного количества битов. ! 7. Способ по п.6, в котором информацию о глубине уровня представляют посредством ИД завершения деления, если определяют, что уровень должен быть самым нижним уровнем, и представляют посредством ИД продолжения деления, если �1. A signaling method for signal splitting information, comprising the steps at which! assigning a number of lower nodes equal to the number of divisions for the lower layer if the upper-level node is represented by a division identifier (ID); and ! do not assign any bottom node to the bottom level if the top-level node is represented by a non-division identifier (ID),! wherein the signal division information includes a division ID and a non-division ID indicating the presence or absence of division of the signal at the level node. ! 2. The method according to claim 1, further comprising the steps of! carry out sequential signaling of top-level nodes; and ! carry out sequential signaling of the nodes of the lower level. ! 3. The method according to claim 1, further comprising the steps of! signaling the lower node of the lower layer corresponding to the first node of the upper layer if the first node of the upper layer is represented by a division ID; and ! signaling the second top-level node if the first top-level node is represented by a non-sharing ID. ! 4. A method as claimed in any one of claims 1 to 3, wherein the depth is discriminated from the split information of the signal. ! 5. The method according to claim 1, further comprising the step of! signaling information about the depth of the level. ! 6. The method of claim 5, wherein the layer depth information is represented by a variable number of bits. ! 7. The method of claim 6, wherein the depth information of the layer is represented by a division completion ID if it is determined that the layer should be the lowest layer, and represented by a division continuation ID if �
