Live Video Feed over one RS232 line (Rx or Tx)

That of course depends entirely on the type of camera you're using. There have been cheap Mattell 640x480 camera's which did use RS232 to tranmit the JPEG converted image to a PC. But generaly, if the camera has I2C, this is only used to set parameters and not to transfer the pixel data.

Well that depends on the sensor size and how patient you are :) With a modern

12Mpixel sensor you'll be waiting a while for each transfer.

Assuming you want to use the RS232 line as intended (and not try to evaluate its suitability for some other signaling scheme) the key to your problem is going to be real time compression.

Your approach should consist of the following:

1) See if you can buy a solution

if not

2) Lab experiment: get two PCs, one with a webcam or other video source, connect them with a serial line and running streaming software such as VLC. Find some compression settings that give you the best plausible performance for your data rate.

3) Build or buy appropriate embedded hardware to re-implement the solution of step #2 in a small / cheaper / more power efficient platform consistent with your (unstated) requirements
