Title:
MULTIPLEXING METHOD AND DEVICE, DEMULTIPLEXING METHOD AND DEVICE FOR REPRODUCTION STATE IDENTIFICATION OF VIDEO DATA
Document Type and Number:
Japanese Patent JP2016131391
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To disclose a decoder of video data.SOLUTION: A video decorder includes a demultiplexing unit for receiving NAL unit data, i.e., a transmission unit in NAL, acquiring NAL unit type information indicating the type of a current picture included in the NAL unit data from the header thereof, and identifying whether or not the current picture is a CRA picture for random access, on the basis of the NAL unit type information, a decoding unit for decoding a video including the CRA picture thus identified. The video includes a picture to be decoded later than the CRA picture, with reference to a picture in decoding order ahead of the CRA picture, when the CRA picture is decoded by general reproduction.SELECTED DRAWING: Figure 19
