Patent ID: 7260829

Claim:
An apparatus that outputs multiple video signals, comprising: first signal processing components, wherein the first signal processing components process a first video signal, the first signal processing components comprising: a first tuner; a first demodulator coupled to the first tuner; a first demultiplexor coupled to the first demodulator; a first video/graphics/text demultiplexor coupled to the first demultiplexor, wherein the first video/graphics/text demultiplexor separates graphics, video and text from the first video signal; and a first video decompressor coupled to the first video/graphics/text demultiplexor; and second signal processing components, wherein the second signal processing components process a second video signal, the second signal processing components also operable to scale and redirect the second video signal, the second signal processing components comprising: a second tuner; a second demodulator coupled to the second tuner; a second demultiplexor coupled to the second demodulator; a second video/graphics/text demultiplexor coupled to the second demultiplexor, wherein the second video/graphics/text demultiplexor separates graphics, video and text from the second video signal; a second video decompressor coupled to the second video/graphics/text demultiplexor, wherein the second signal processing components are an upgrade to an existing set top terminal to provide digital picture-on-picture capability; a third signal path having third signal processing components, wherein the third signal processing components process a third video signal, the third signal processing components also operable to scale and redirect the third video signal, wherein the third signal processing components are substantially identical to the first and the second signal processing components, and wherein the first, second and third video signals are displayed simultaneously on a display; audio decompressors in the first, second and third signal paths; and a switch coupled to the audio decompressors, wherein the audio decompressors provide audio signal associated with video signals, wherein the switch operates to select an audio output from one of the audio decompressors.
