Abstract

A signaling method for signal division information is disclosed. The signaling method divides a signal into several signals, and effectively represents division information of the divided signals. The present invention provides the method signaling for signaling signal division information comprising:
assigning number of lower nodes equal to the number of divisions to a lower layer if a node of an upper layer is represented by a division identifier (ID) ; and un-assigning any lower node to the lower layer if the node of the upper layer is represented by a non- division identifier (ID), wherein the signal division information includes the division ID and the non-division ID
indicating the presence or absence of a signal division at a node of a layer.

Claims (8)

1. A signaling method for signal division information comprising:

assigning number of lower nodes equal to the number of divisions to a lower layer if a node of an upper layer is represented by a division identifier (ID); and un-assigning any lower node to the lower layer if the node of the upper layer is represented by a non-division identifier (ID), wherein the signal division information includes the division ID and the non-division ID indicating the presence or absence of a signal division at a node of a layer.
2. The method of claim 1, further comprising:
sequentially signaling nodes of the upper layer; and sequentially signaling nodes of the lower layer.
3. The method of claim 1, further comprising:
signaling a lower node of the lower layer corresponding to a first node of the upper layer if the first node of the upper layer is represented by the division ID; and signaling a second node of the upper layer if the first node of the upper layer is represented by the non-division ID,.
4. The method of any one of claim 1 to claim 3, wherein a depth is recognized from the signal division information.
5. The method of claim 1, further comprising:
signaling layer's depth information.
6. The method of claim 5, wherein the layer's depth information is represented by a variable number of bits.
7. The method of claim 6, wherein the layer's depth information is represented by a division-termination ID if the layer is determined to be a lowermost layer, and is represented by a division-continuation ID if the layer is not determined to be the lowermost layer.
8. The method of claim 7, further comprising:
signaling nodes of assigned to an (M-1)-th layer if the lowermost layer is an M-th layer.
