I have a home PVR setup. My Dish Network STB is connected to my computer through an S-Video cable. I needed to write a script so that my IR Blaster would communicate with the STB. But will the script even transmit across the S-Video cable or does the connection have to be coax?
S-video can only carry VIDEO data, there is no control mechanism or bus. Your script should control the IR blaster via a special cable. the IR blaster sends an IR command to the STB to change channel. The STB changes channel and you see the video on the S-video cable.
