PROBLEM TO BE SOLVED: To provide a signaling system and a signaling method of the POC of a long term reference picture, with less overhead of referencing picture.SOLUTION: As the information for tracking a reference picture on a decoder, an encoded syntax correcting the buffer description, containing 'a wrapped POC' and poc cycle for signaling a long term picture, is used. In the bit stream, the buffer description contains POC (picture order count) cycle parameters related to the long term reference picture. The POC cycle parameters are used for calculation of the picture order count (POC) related to decoded long term reference picture. Based on the picture order count (POC), one or more decoded reference pictures related to the current picture are specified from the decoded picture buffer.SELECTED DRAWING: Figure 4
