Audio/video from RCA output to computer over 1Gbps pre-configured CAT5e Ethernet?

[techno_race]

I have a video device (no other details necessary) with a 480p composite-video, stereo-audio (RCA) output. I want to be able to view the video from this output on a computer in a separate room using my existing 1Gbps CAT5e Ethernet configuration wired throughout my home. (It does not need to be connected to any other devices, such as a TV set.)

Moving it and using a video-capture card is not an option. I need a way to convert the 3-plug RCA output to an Ethernet cable that can be plugged into my existing 1Gbps router/switch combination.

The video must then be able to be watched in real-time, in its full 480p, stereo quality, on a Windows 7 computer (though using a virtual machine with a different Windows or Linux OS is an option) in a different room that is also connected to the same home network with a CAT5e cable and another 1Gbps router/switch combination.

I've looked around (yes, I Googled it), but nobody seems to know what they're talking about (or they do seem to know what they're talking about, but it's in a 1997 newsgroup post and terribly outdated).

Is this possible? The solution MUST not involve the use of a video-streaming service or exiting the home network and accessing the internet in any way.

In short, I need to stream stereo audio and 480p video from an RCA output to a Windows or Linux computer over an existing Ethernet configuration, and be able to watch it in real-time on said computer in full quality, without it ever accessing the internet (it must still work, for example, if we have an internet outage).

Have you checked out the Slingbox products? The convert a video and audio source to ethernet. It is advertised as going on the internet, but I wonder if you couldn't just stream through your house network without going out on the internet.
