What do you mean by "connector for digital TV"? Monitors/TVs are already
available with DVI and/or HDMI inputs. In the US, TVs are already available
with ATSC tuners. (Most of the world uses a different standard for OTA,
so they need a different tuner.)

Yuri, we do not know what you intended, but what you wrote appeared
to suggest having a graphics/video card in a computer which sends
its output via Ethernet instead of DVI.

This still sounds like you want to decode the compressed video
in the computer, then recompress it so that it fits in Ethernet,
then uncompress it again close to the display.
Why decode (aka decompress) it just to compress it again? That is a
LOT of extra work.
The easier way is to send the compressed video (mpeg2, mpeg4, H.264, ...)
out the Ethernet, and to have a small box near the display that decodes
the video and outputs DVI/HDMI/s-video/... Compressed HD video will
easily fit on 100 Mbps Ethernet. You do not need a graphics/video card
in the computer to do this, all you need is an Ethernet port. Put the
"video card" in a small standalone box with Ethernet in and DVI out.

The output of a video card is very high bandwidth. A gigabit Ethernet
isn't fast enough.
