Publication number: 20080304513Abstract: 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.Type: ApplicationFiled: July 28, 2006Publication date: December 11, 2008Applicant: LG ELECTRONICS / KBK & ASSOCIATESInventors: Hyeon O Oh, Hee Suk Pang, Dong Soo Kim, Jae Hyun Lim, Hyo Jin Kim, Yang Won Jung
