Abstract: Apparatus and method for processing a vertical blanking interval (VBI) signal and video signal are provided. An exemplary apparatus comprises a VBI decoder, a mixer, and a TV encoder. The VBI decoder is configured to receive and decode the VBI signal to generate a decoded VBI signal. The mixer is configured to mix the video signal and decoded VBI signal to generate a mixed signal. The TV encoder is configured to encode the mixed signal to generate a first TV compatible signal for TV display. After receiving the first TV compatible signal, the TV not equipped with a VBI decoder can display the contents of the video signal and VBI signal.
