    摘要: Provided are a time-stamping apparatus and method for RTP packetization of a SVC coded video, and a RTP packetization system using the same. The time stamping apparatus includes: a NAL unit classifier for checking a header of an input NAL unit and classifying the input NAL units based on a picture property; a first timestamp calculator for calculating a RTP timestamp value for a NAL unit classified as a key picture by the NAL unit classifier; a second timestamp calculator for calculating a RTP timestamp value for a NAL unit classified as a non-key picture by the NAL unit classifier; and a controller for setting a RTP timestamp value for an instantaneous decoding refresh (IDR) picture and controlling the first and second timestamp calculators for calculating a RTP timestamp value of a corresponding NAL unit.
