He has a RF modulator and a notch filter so he can redistribute the output of the tivo to any room in the house. Would the same thing be possible with 6412 ? How does it get its guide data and firmware updates ?
Not sure what you mean by addressable. Unlike Tivo or ReplayTV 6412 gets everything from cable provider via digital cable channels, so no network or phone connection is needed. It is important, however, to have clean return path similar to Internet cable modem, so you can't have old inline amplifiers. If you must amplify signal you have to use bidirectional amps.
My setup is similar to your friend's. I split incoming signal 3 ways - to cable modem , 6412, and Channelplus DA-550 amp/distr panel through lowpass filter. Then, composite out from 6412 goes into Channelplus modulator, which then feeds into DA-550 modulator input. Result: up to 8 TVs across the house get equally strong/clean signal with up to 4 local modulated channels, one of which is 6412 output. I use others to distribute 400 disk DVD changer and VCR across the house.
One problem with 6412 in this setup: there is no graphics overlay on HD channels over composite output. Ex.: when you watch HD channel from 6412 on remote TV over modulated "house channel" you can't see iGuide or any DVR controls. I learned to blindly control the box or switch to non HD channel.
Hope this helps.
