Abstract:
1. An apparatus for supporting synchronization of Scalable Video Coding (SVC) information and Advanced Audio Coding (AAC) information using a Normal Play Time (NPT), the apparatus comprising: an information receiving unit to receive video information and audio information using a decoding apparatus; a video information analysis unit to calculate the NPT of the video information using a Real-time Transport Protocol (RTP) time stamp included in the received video information; an audio information analysis unit to calculate the NPT of the audio information using the RTP time stamp included in the received audio information; a calculation unit to compare the NPT of the video information and the NPT of the audio information to calculate a difference value; a determination unit to determine whether the calculated difference value is included in a specific synchronization region; and an output unit to output the audio information and the video information when the calculated difference value is determined to be included in the specific synchronization region.
