Broadcast monitoring in today's world

摘要

Broadcasters are increasingly moving over from SD transmission to HD transmission. At the same time, the volume of ancillary data transmitted alongside video is growing considerably. Vector scopes and TV waveform monitors are completely inadequate for delivering test and measurement in this environment. In this article MIKE HODSON, managing director of OmniTek, looks at the requirements being placed on today's monitoring systems and at the highly complex signal processing systems that are needed to perform this role.
