Reading text in Video Signal

[KDANDAVATE]

Hi,
I am working on video based project. This project not involved any computer so i have to work with microcontroller to read the text in video signal. Well I am able to grab the video frame in RAM but don't understand how to read the text as it is stored in pixel values(color info also),& i want to use this text for comparison.
Can Anybody Help me Please?

Are you talking about OCR (optical character recognition) on the picture itself, or reading the closed caption signal embedded in the video?

The first is very difficult, if not impractical. The second is easy and I expect you can search for "closed caption" on the Web and find the embed format and probably a project which already reads it.
