WGSR now has something more to show than analog static. We have the signal back up, thanks to some conventional computer technology.
Turns out that the link between studio and transmitter has been up and running the entire time since we installed it. All of the failures that have happened in our system have been in encoder, mux and the gear that connects them to the link, either on the studio or the transmitter end (and at least once, BOTH).
What got our system working again was Windows streaming technology. We're running a server with a very fast processor at the studio end streaming the video down the link to the transmitter. On that end, another computer with a very fast processor is decoding the stream, and a converter box changes the video from VGA to NTSC to feed the encoder.
All that remains is a little fine tuning of the NTSC analog video and an audio amp to bring up the sound to a reasonable level. I anticipate that the computers will require more maintenance than "hard-wired" boxes, but we're hoping that this system will perform with a reasonable amount of reliability until we find a supplier with equipment that more closely meets our needs for price and stability.
We have returned our digital signal to viewable quality with our own in-house efforts and not those of professional engineers. Turns out that we have some great talent at WGSR that, as this situation has turned desperate, have banded together to solve problems that we have been waiting on professionals to fix for more than six weeks.
I'm not sure what is going to happen now with some $30,000 of digital broadcast equipment now sitting useless and idle in our studio and transmitter racks. Heartland video, who we bought our gear from, has been a bear to deal with in both helping us solve issues and replacing equipment identified as not up to the needs of our situation by the engineers we hired to put it in. On more than one instance, Heartland told us their equipment was working and blamed the link transmission system, which has proven to be solid and reliable. They definitely should not use us as a reference.
We're looking at alternative encoders, and the multiplexer equipment to let us add at least one subchannel, which will probably go live early in 2010. Plus, some of you may be aware that Star News Corporation has purchased W18BG in Danville. Build-out of its digital signal on Ch. 23 will begin this fall. We're taking all of the bad experiences we've had going digital with WGSR, and promised ourselves that they will not be repeated with W18BG.
Give us a look, and if you see anything in our signal we can improve, let's discuss it here.
