Cable Converter Box



Can you purchase a single converter to put on the main cable line, so you don't have to have a converter box for every tv in the house?

You can, with some gotchas.

First, if you simply connect the output to your home's coax inline, every TV will be displaying the same channel unless you get a really expensive solution with receivers and modulators like the cable headends do. At that point you may as well just get a converter box for every TV.

You'll need some means to control the box. Probably an IR extender of some sort.

RadioShack and others sold a home video distribution system where you could share a VCR or other device across multiple TVs by inserting channels in the UHF spectrum. Basically a mini cable system for your home. Still available: Channel Plus 3025 Multi-Room Video Distribution System - Smarthome

But really if you're going this route you may as well just get a converter box for each TV, and there are so many better ways today to distribute video such as a HTPC and XBOXes.
