We need to buy/build a PC that has a direct-connect cable TV video adapter (for signal in), software to record, rewind, play, pause, and screen capture a still frame that easily exports to JPG, uses a standard PC monitor, and stores the recorded programming to hard disk (and/or other media).
For example, we would like to monitor and continuously record a television program until a particular segment appears. Then have the ability for the operator to stop, rewind to a particular frame, then screen capture the image and export it to a standard jpg on the same PC.
I'm not sure whether current technologies can handle this efficiently, but thought I would see what others can share on the topic. Thanks in advance.
There is currently an item called Tevo, and it allows you to do this.
Also, you could just buy a "Media Center". Lost of computer manufatures offer them, and they have all this already set up for you. Most of them even have remote controls. Just Google PC "Media Center" [google.com] and you'll com up with ways to create your own "Home Theater" using your computer.
