I am a current Directv user in central virginia with 3 sat receivers (1hd, 1tivo,1sd). In reading the forums, I believe at sometime in the future, all my current directv equipment will eventually be upgraded with new stuff to handle the new satellites, mpeg4, etc. My question is where can I find a block diagram for typical setups. I would like to be knowledgable when I have the need or opportunity to upgrade to understand my whole setup works. I see a dish (5lnb), a multiswitch, and multiple receivers. Not clear is #cables from dish?, and where is multiswitch installed (roof, attic, basement? other), and # cables from multiswitch to receiver(s). and any other gotchas? hd received on 1st floor with hd tv, other receivers in basement. Any pointers or info appreciated. Thanks Andy

Well if you only have those 3 receivers (the Tivo having 2 tuners), they probably won't install a seperate multiswitch. The 5-LNB dish has a built-in 4 port multiswitch, so you don't need a seperate multiswitch unless you need more than 4 tuners.

The new dish still has 4 outputs and a built-in multi-switch just like the phase III, so you dont have to change any wiring, just install the new 5LNB and change to the MPEG4 based receivers when the time comes, which is still several years away b4 they will force a switch from mpeg2 to 4......

The only 2 changes involve using a different multi-switch(currently a Zinwell WB68) if you need more than 4 cable runs, and you cant diplex an OTA signal on the cables anymore as that frequency bandwidth will now being used by the sat signals...so you'll need a seperate antenna feed to each OTA receiver...

The best way to describe what you would do is this:

- New MPEG4 dish has 4 outputs
- NON DVR, SD and HD receivers require 1 input
- SD and HD DVRs require 1 input but operate best with 2 inputs

So for your current set up (1hd, 1tivo,1sd), you only need 4 outputs from the dish and do not need a multiplexer. If you ever change or add more receivers and need more than 4 outputs from the dish, you will need a multiplexer which creates 8 outputs from the 4 the dish has. The multiplexer can be installed outdoors or indoors. The only constraint to where you install it is that it has to have all four outputs from the dish...so it needs to be located at a place BEFORE the lines separate and go different directions to different locations in your house.

All correct except change multiplexer to multi-switch....a multiplexer is something else....

Yes, exactly right, I call it a multiplexer, but I mean multi-switch, sorry about that...
