      We use a rack of DVD players with software controlled timing to broadcast video thru our local cable. This obviously requires encoding and burning the content to DVDs (hassle and time).
      We want to use a PC with a monster hard drive together with software that will play avi files out an interface.
      Is there not an inexpensive software that will play avi files at scheduled time out an interface (coax?)?
      I have found some professional ones out there; but surely its not that complicated–I can’t beleive there’s not a demand for it.
      Or am I missing some obvioulsy easy wasy to do it?

      We just completed an overhaul of our system at Community TV of Santa Cruz, we have 3 channels 24/7/365. I researched for over a year for the right product for us. We finally settled on a hybrid combination of MPEG-2, DVD and yes, still 4 S-VHS decks for some things. While I was researching I considered briefly a product from Princeton Server Group. I can’t remember prices, but they had one of the lowest costs of the “professional” products on the market. They did not have the sophisticated automation control built into their system which we required for our many devices. they are at

      In my research, I found a couple of other mom & pops like princeton. Holler back at me if you have any questions.

      Thanks Craig-
      I had seen the Princeton products before. We are on a definite “shoestring” budget and are looking for something a little more…unprofessional.
      So far, I’ve found Digital Video Play
      Both of these are not US companies. Play
      If you know of any other simple broadcast automation systems, please let me know.
      What kind of interface would the PC need to have to provide video into the cable system? Is this a standard card you can buy? Or more complicated than that? Does it have to be encoded to broadcast?
      Thanks again for your reply.

      I know the Rushworks product but not the others. Rushworks was a finalist for our project, but we decided to go with more of a Chevy 350 than a beta product. Rushworks is a small company and though I liked their product very much, the project was $80,000 so we went with Tightrope Media Systems. They are solid but maybe out of your budget. As for your other questions; What you put out depends on what connection and type of signal the cable company is expecting to get from you. We put out NTSC composite video and Stereo balanced audio that are fed to fiberoptic transmitters that are received at the cable companies head end. You should ask your cable companies head end engineer what terminations ans signals they expect to use. As for your PC’s output. Your best quality output will come from a dedicated decoder card that has broadcast quality out puts for video and audio. Most PC video cards that do have either NTSC or Y/C video outputs combined on the same card with DVI and VGA generate dubious quality from those additional outputs. Quality enough for a “show string” but not to be used unless you have no other choice.

      Craig, holler if you have more questions
