RE: HD Structured Wiring?

Posted by blue_z on July 28, 2007 at 18:39:39:
Hi there
Cat5 is adequate for networking, but you will need Cat5e for Gigabit speeds. I'd rather install Cat6.
RG-6 can carry baseband video (aka composite video), but is typically used to distribute RF signals, either cable TV (analog NTSC or digital TV (ATSC QAM)) or broadcast (over the air, OTA) analog NTSC or digital ATSC 8VSB. The cable and OTA digital TV could be standard def or High def channels. Since the channels are modulated RF signals, the RG-6 coax would have to be connected to some kind of tuner. If the signal is cable or satellite TV, and preminum (encoded) channels are to be received, then that tuner has to be a compatible STB (set top box).
Digital TV is really a data stream, and can also be sent over the network. There is at least one device, HD HomeRun, that consists of 2 ATSC tuners that can forward one or 2 tuned channels on the Ethernet network. Since there are not many (any?) networked displays yet, the receiving ends of the data streams would be PCs.
If you have only one cable box, that means you have only one TV tuner. If you have eight "outlets", did you want to send the one tuned channel to all eight displays at the "outlets"?
Typical use for the structed wiring is probably:
Cat5 : phone
Cat5 : computer network
RG-6 : OTA TV, both analog and (SD & HD) digital
RG-6 : subscription TV (cable or satellite)
