Hoping someone on this forum is able to help with this or at least make good suggestions.
I'm the tech at an elementary school. You give me a network or computer issue here and I can fix it, but I'm not sure if what I want to do with our coaxial TV system is possible.
Right now we have the TV cable in, which gets split to 1 cable box (for channels over 100) and to 4 different VCR/DVD combos. Each of the 4 VCR/DVD decks is set to show a different cable channel. The audio and video out from the cable box and the VCR/DVDs are then sent to their own headers which combines and encodes them to broadcast each on a certain channel. With this setup, we can only broadcast 5 TV channels to all the TVs in the school at a time, plus our school news which feeds directly from the studio into a header.
Having to go back and change channels on the VCR/DVD decks can be a pain and it limits what channels teachers can use, more so if any of the VCR/DVD decks is being used to show a video school-wide, and we've already had 2 VCR/DVD decks die and can't replace them right now.
What I would like to do, if it's possible, is to filter out 6 cable channels (low number ones, except 3 since that's PBS and we want to show that one) coming in and replace them (using the headers) with our own, while still retaining all the other basic cable channels.
Cable in --- filter ----- Deck1 ---------------|
|_ Deck2 ---------------|
|_ Deck3 ---------------| ------ out to school TVs
|_ Deck4 ---------------|
|_ Cable Box ----------|
|_ School News ------|
|_ all other channels |
Hopefully I've explained our current setup and preferred setup and someone understands what I'm talking about and can make suggestions on what I need.
