About Jack Dominic

I have worked in public broadcasting for more than 30 years and currently serve as the Chief Operating Officer here at CET, the nation’s first licensed non-commercial TV station. CET is a pioneer in traditional television production and distribution as well as an innovator in an array of new media such as our recently launched broadband video service called “CETconnect.”

I have another blog that covers other technology issues that you might enjoy.  I have posted most of my newspaper articles there.  www.jackatcet.blogspot.com

    Mr. Dominic,

    I came across your CET Tech Info Blog and wanted to thank you for your efforts to educate the public on television’s conversion to digital. I have a question for you; hopefully it is not too advanced for the blog but if so maybe you can answer it for me anyway. When analyzing the signal that WCET-DT sends out, in additional to the video and audio streams for CET-HD and CET-World, I notice some other data streams that are not present in other local stations’ signals. I’ve noticed that these data streams can use up 2Mbps or more of the 19Mbps available in an 8VSB channel. Could you tell me what these additional data streams are?

    On a possibly related note, my television’s guide system (TV Guide on Screen) provides me with programming information for all of the channels I receive. I am OTA-only (why pay for TV when you can get great HD from CET and other local stations) so I am wondering where my TV gets the data from! I have heard rumors that some PBS stations send this data, encoded in their channels. Is this true?
