Time-stamping apparatus and method for rtp packetization of svc coded video, rtp packetization system using that

The present invention is a timestamp value for a time stamp generating apparatus and a method for RTP packetization of the SVC video and relates to RTP packetization system using the same, the first screen of the IDR (Instantaneous Decoding Refresh) screen of the SVC bitstream setting and using the input NAL (Network Abstraction Layer) screen properties of the header information of the unit and TL (Temporal_Level) is generating a time stamp of the NAL unit, the time stamp for the RTP packetization of the SVC video generation apparatus and to provide a method and system using RTP packetization him. To this end, the present invention relates to a time stamp generating unit for SVC (Scalable Video Coding) RTP (Real time Transport Protocol) of the video packetization, by examining the headers of (Network Abstraction Layer) inputted NAL unit according to the display attributes NAL unit classification means for classifying; First time stamp calculating means for calculating a RTP timestamp value of the NAL unit that corresponds to a key display classification in the NAL unit classification means; The second time stamp calculating means for calculating a RTP timestamp value of the NAL unit that does not correspond to a key screen classification in the NAL unit classification means; And IDR (Instantaneous Decoding Refresh) set the RTP time stamp value for the screen, and control means for controlling the first output time stamp means and said second time stamp calculating means for calculating a RTP timestamp value of the NAL unit It includes. SVC video, RTP packet timestamp, NAL units, screen properties, TL
