ABSTRACT:
A method and system for including non-graphic data in an analog video output signal of a set-top box. Graphics data is generated from and represents non-graphic data using software or firmware that is executed by a processor, system-on-a-chip integrated circuit, or some other component of the set-top box. The graphics data is alpha blended with video data that is extracted from a digital television signal. This alpha blending results in an alpha blended digital video signal. The alpha blended digital video signal is converted into the analog video output signal by a digital encoder function, which is preferably included in the system-on-a-chip integrated circuit. The alpha blending is also preferably performed by the alpha blending function of the system-on-a-chip integrated circuit. The analog video output signal can then be input into an analog video recorder.
