Communication Networks for the Remote Control of Television Equipment: Interim Report from the SMPTE Ad Hoc Group on ESnet

Marc S. Walker

For over 12 years, SMPTE and EBU committees have been working in cooperation on machine-control standards for television equipment. This work has resulted in the highly successful ESbus hardware specification, ANSI/SMPTE 207M, which has been accepted worldwide, resulting in a number of devices with 9-pin connectors and RS-422 control. The time has come for a higher performance level in a hierarchy of control systems. The Ad Hoc Group on ESnet has been looking at various candidate networks, and has made recommendations for a communications network and control protocol to its parent committee. The issues involved in selecting a network are discussed in this article.
