Abstract
A graphics display system processes text data in a video signal, preferably in the vertical blanking interval, and allows a user to selectively display the text data in real time, search the text data, or obtain a transcript of the data. A digitizer and decoder circuit extracts the text data from a video signal and adds an identifier to the text data. A graphics user interface accelerator stores the text data. Concurrent with adding the identifier and the storage of the text data, the digitizer and decoder circuit adds an identifier to the video and audio data, and the graphics user interface accelerator stores the video and audio data. The identifier added to the video and audio data links such data to the associated text data. In response to a user search request, a host processor scans the stored text data for text data that matches a user selected input, and retrieves the text data matching the user selected input. In response to a user command, the host processor retrieves the video and audio data having an identifier matching the identifier of the retrieved text data. The graphics user interface accelerator displays the video data and plays the retrieved audio data. In response to another user command, the host processor provides the retrieved text data to an external device for printing.
