HD test, measurement demands ability to modify datastream

Karsten Hansen, CEO of DK Technologies in Herlev, Denmark, sees the need for a significant changeover in the test, measurement and monitoring equipment needed to maintain HD quality.

It isn’t enough simply to give broadcasters the tools to monitor and interrogate an HD signal; they also should have a means to make modifications to the HD datastream when needed. According to Hansen, that’s especially true when it comes to metadata, 5.1 surround-sound information and closed-captioning that are part of the HD signal.

This week, Hansen discusses the test, measurement and monitoring challenges of HD and his company’s approach in an audio podcast.
