Abstract
An integrated receiver decoder is provided for allowing simultaneous transmission of compressed and uncompressed signals for an audio/video program. The integrated receiver decoder includes a demodulator for receiving a modulated carrier signal and extracting a baseband signal therefrom. The demodulator transmits the baseband signal to a demultiplexor. The demultiplexor extracts a selected compressed signal from the baseband signal. The demultiplexor then transmits the selected compressed signal to a compression decoder for converting the selected compressed signal into a selected uncompressed signal. The compression decoder then transmits the selected uncompressed signal to a graphics overlay device for blending the selected uncompressed signal with user interface graphics. Thereafter, a digital transport device combines the selected compressed signals with a blended uncompressed signal so as to produce a multiplexed signal for transmission through a universal interface output.
