SRTS Application in High Speed Transmission System
Sun-Ting Lin, Chih-Hsuan Chang · 2007
Synchronous residual timing stamp (SRTS) is a technique originally used for encoding and transporting synchronous timing information for constant bit rate (CBR) traffic over asynchronous transfer mode (ATM) network. Recently, this technique can also be applied to other services with higher transmission rate such as video broadcasting up to the order of Gbps range such as high definition television (HDTV). The corresponding clock rate of transmission link for those high bit rate video services should be 2.48832 Gbps (Synchronous Transport Module-level 16, STM-16) instead of 155.52 Mbps (STM-1). The clock recovery is necessary since the service clock for the video signal is asynchronous to the network clock. To apply the SRTS method in a new service with different transmission rates, the related parameters should be analyzed and redesigned. In this paper, we build up the SRTS transmitter and receiver as well as analyze the jitter performance at the high bit rate services to minimize jitter generation in the SRTS method.
