It is already being done in some cable areas. with cable equipment.EndBoards said:I've been thinking about different options & workarounds for the lack of MRV, and thought of something that might be avenue for Tivo (or someone) to explore. Why not change the whole architecture of the DVR? Instead of a set top architecture, go with more of a server/client(s) architecture..
Start with a centralized "dvr server" containing say 3 cablecard tuners - basically an S3-and-a-half in a single box. This server streams content to nodes located throughout the house. The nodes convert this stream to A/V output for whatever display/sound systems you have and also receive commands from remotes.
I got the idea from the slingbox type distribution systems that send component video and IR commands over Cat5. You can achieve a form of MRV with this system and a pair of DVR's, but you still have to manage and switch between two independent DVR's. So why not integrate the whole thing? One DVR that can show multiple sessions anywhere in the home.
Drawbacks: Obviously, I'd guess that it would take a pretty powerful server, not to mention Cat5 throughout your home, and maybe a gigabit network. To satisfy CableLabs you'd probably still have to convert protected content to analog before streaming...
Benefits: One DVR to manage, content is viewable anywhere in the house, enough tuners to satisfy most families, no files to transfer, no STB to deal with... You could also go to a more user based rather than location based management scheme. Instead of "living room", "bedroom", etc.. A user selects his name and sees his own shows, channel lists, configuration options, etc... These options carry to whatever node he happens to be using at the time..
Ok... fire away..
