Integrated receiver decoder and method for simultaneously transmitting compressed and uncompressed signals
First Claim
1. An integrated receiver decoder comprising:
- a demodulator receiving a modulated carrier signal and extracting a baseband signal from said modulated carrier signal;
a demultiplexor coupled to said demodulator and receiving said baseband signal therefrom, said demultiplexor extracting a selected compressed signal from said baseband signal;
a compression decoder coupled to said demultiplexor and receiving said selected compressed signal therefrom, said compression decoder converting said selected compressed signal into a selected uncompressed signal;
a graphics overlay device coupled to said compression decoder and said demultiplexor, said graphics overlay device receiving said selected uncompressed signal from said compression decoder, said graphics overlay device receiving said selected compressed signal from said demultiplexor, said graphics overlay device blending said selected compressed signal and said selected uncompressed signal with a plurality of user interface graphics; and
a digital transport device coupled to said graphics overlay device, said digital transport device receiving said selected compressed signal and said selected uncompressed signal from said graphics overlay device, said digital transport device combining said selected uncompressed signal and said selected compressed signal into a multiplexed signal for transmission through a universal interface output.

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.
