Testing Digital HD Using SD Principles With Faster Data

摘要

It isn't easy being a video professional today. You need to accurately test, measure, monitor, and generate baseband video in a world that is transitioning from analogue to digital. And you are expected to accommodate multiple formats in a single environment, while boosting productivity and cutting costs. The typical broadcaster and production studio will operate in both standard and HD video formats. A benefit to the broadcast engineer is that today's digital HD test and measurement equipment is also designed to work in a SD environment. This is certainly the kind of challenge in which the calibre of your tools is critical for continued success. The device used to illustrate this article, the Tektronix WFM700 series multi-format, multi-standard waveform monitor, is configurable for any of the SD and HD component digital formats in common use today. There will be many changes in the future. The author hopes that you will find the transition to HD most rewarding.
