I have heard that the HD or HD DVR receivers can output video and audio only over cat6. where no component/HDMI is used to receive video signal. Is that correct? if so can someone please explain to me how that works. Also if it is possible would there be a way to digitally record that feed to a computer over the cat6 cable?

Briefly, through the "Whole Home DVR Service" (WHDVRS @ $3.00/mo.) DIRECTV HD DVRs may receive or stream recorded programming to other HD-DVRs by ethernet or over coax networking known as "DECA" either by an internal or added external adapter for older receivers.

HD receivers may only receive streams from other HD-DVRs by means of the same in/external adapters except for the H25 which can only be coax networked through its internal DECA and has no ethernet port.

You may stream programming from an HD-DVR to a PC using an application called "DIRECTV2PC," but for viewing only.

You may not record them to a PC's HDD though.

The new HR34 and RVU client(s) or "Genie" system is a whole other issue,

Is it? Doesn't whole home DVR service (2 HR24s for example) over coax use a form of RVU implementation? Is it different protocol and spectrum than say a c31 communicates to an hr34?

DirecTV2PC and/or WHDVR DVRs only transmit recordings over the network. They will not transmit live TV.

Genie/RVU offers the full DirecTV "experience" including UI over a network.

In either case the video stream will be encrypted (DLNA), so capturing is unlikely.

Understood. But I'm asking is the transport mechanism (frequencies assigned and used on the coax and the communication protocol) between boxes different or is it just the features supported for a c31 client that is different?

Stated differently. If I have a hr34 and a C31 as well as an hr24 all on the same whole home DVR network, is the fundamental video transport protocol/mechanism on the coax for the hr34 and c31 client different than between the hr34 and hr24? Not the features supported. The communication/transport mechanism.

Yes they are different. HR34&C31 use the RVU protocol while HR to HR or H use "whole home" protocol using DECA or the unsupported Ethernet connection. RVU is only supported by the HR34 and C31 and some select Samsung TV's. I'm not sure anyone but directv would know exactly what "Whole home" is but we do know its not RVU.

Google mid-rf moca , in the simplest of answers.. No what your asking is not possible .

It's like using a balun.. It's just using the cat 6 as a mechanism to transfer the signal , it requires the same "decoder" at both ends.

I had confused MOCA and RVU. Its been a while since I had read on the topics. They can go together I see (RVU can be via MOCA or ethernet or....), but MOCa dn RVU are not the same.

That said, what communicationa/linking mechanism is DirecTV using for their RVU implementation (HR34 and C31 or RVU compatible Samsung TV)

They use MOCA via the built in DECA on a C31 or a broadband DECA for a non-DirecTV client.

Which gets back to my original question. I see now the transport mechanism for both RVU clients and directv's proprietary whole home DVR service is MOCA utilizing external or internal DECAs. The communication protocols/standards for the two services are different, but I deduce they can both simultaneously exist on the same in home MOCA network

One thing common between WHDVR and RVU is both use TCP/IP for the transmission protocol.

See post My Setup for configuration info.

So now google ... Mrv frequencies , and then google connecting RVU TV to HR34. It will start
To make sense ..
