722 Vip high def at both TVs even through Coax?

Dish network is telling a client of mine that it is not possible to have HD on his second TV that is recieving it's signal through the existing Coax.....He has the Vip722, which I though was dual HD receiver, am I wrong?

The coax connection only carries an SD signal. The only way to get HD on 2 sets is to connect component to one and the HDMI to another. In this case, though, both sets would get the same channel (same concept as splitting a coax signal).

Dish Network is correct. Although the ViP 722 may be a dual tuner HD receiver that only means that you can watch one HD program while recording another.

I just leave my vip 722 in TV1 mode and the home output with coax to my HD tv in the bedroom and the picture is in HD, black side bars if the particular program is not HD. Example HLN ch 202 is not in HD, CNN ch 200 is in HD

We have 3 HDTV's, so I have a 722K and 2 211's all three have EHD, so I can archive off the 722k and have recording capability on the 2 211's with NO DVR fee on the 211's.

Interesting. My 622 performs like Loves2Watch mentioned, that is HD output is only out of the TV1 connections.

All of the TV one connections are active, so I have a signal coming out of HDMI, component, S-video and Composite.

Only HDMI and Component have the bandwidth to handle an HD signal, the other connections are converted in the receiver to SD.

I can connect every connection to my TV and switch inputs from Composite, S-Video, Component and HDMI. My TV fills the screen for me, but the signal is defiantly not HD.

On HDMI or Componet, the my tv info screen brings up the signal coming into it 1080i - 16:9.
With S-Video or Composite the info screen just brings up NTSC.

If it's over coax the picture is definitely not HD, the cable can only carry 480i (SD) signals. If the receiver is set to an HD channel, what you see on a TV connected to the receiver by coax is an SD downconverted version of the HD picture.

That's funny...Comcast sends HD over cable.

Poster was referring to coax output from Dish receivers.

Commie Cast encodes all those channels QAM.

I believe an inexpensive QAM encoder is about $500, agile QAM modulator $1,000+.

Programming providers do not want and probably would not allow Dish to "rebroadcast" ATSC throughout your house (you might record an HD digital copy for yourself).

Look at this DIY. http://www.zeevee.com/connected-home Still one channel at a time.
