摘要：
A method of supporting synchronization of Scalable Video Coding (SVC) information and Advanced Audio Coding (AAC) information using a Normal Play Time (NPT), the method including: receiving video information using a decoding apparatus; receiving audio information using the decoding apparatus; calculating the NPT of the video information using a Real-time Transport Protocol (RTP) time stamp included in the received video information; calculating the NPT of the audio information using the RTP time stamp included in the received audio information; comparing the NPT of the video information and the NPT of the audio information to calculate a difference value; determining whether the calculated difference value is included in a specific synchronization region; and outputting the audio information and the video information when the calculated difference value is determined to be included in the specific synchronization region.
