摘要:
The disclosed embodiments relate to a system that inserts closed caption information into an analog video signal. An exemplary embodiment of the system includes a first buffer adapted to store a current frame of closed caption data, a second buffer adapted to store a next frame of closed caption data if the first buffer is full, a third buffer adapted to store a frame-after-next-frame of closed caption data if the first and second buffers are full, and an analog video encoder configured to encode closed caption data from the first buffer, the second buffer and the third buffer into an analog video signal.
