Abstract
A system and method employs a single port digital video and/or audio capture circuit that is responsive to digitized uncompressed digital video and/or audio data and vertical blanking interval (VBI) data. In one embodiment, the single port capture circuit employs a parsing circuit that parses received VBI data along with any other received data such as video data and/or audio data and serves as a memory control signal generator that generates a VBI memory control signal and at least one of a video memory control signal and/or audio memory control signal to facilitate storage of the parsed VBI data, video data and audio data (if present) into predefined distinct locations within a memory, such as a frame buffer. A write FIFO memory receives the video data, VBI data, video memory address data and VBI memory address data (and audio information if present) as a storage hold prior to being stored in the frame buffer.
