| Abstract: | An embedded CCTV method over MSTP is introduced in this paper.Some key features are shown,including uni-directional inverse multiplexing,synchronization scheme of E1 which is used for asynchronous octet mapping and distributed video switch.The delay time for video & switch and also the affect of PCR are analysized.Typical applications which using such method are given. |
