Abstract
Abstract A method and apparatus for sending digital audio data and/or digital graphics within available bandwidth used to carry television signals into end-user homes and offices, such as, additional bandwidth which will become available as optical fiber replaces cable currently in use to carry cable television programming. The invention also makes it possible for digital audio and graphics, including computer generated data such as output from a word processing, paint or real time file builder program, to be sent over any regular television channel on any cable system. The system could even be used on a television signal broadcast at a normal broadcast frequency if the signal received in the home is of high enough quality. The system utilizes existing cable decoder boxes which have been improved by the addition of a decoder which decodes a composite or RF video signal containing digitized audio to audio, and optional additional signal processing, for playback or recording by existing consumer electronics audio equipment.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
129 words
A system for delivering digital data encoded in a video signal comprising: a) recording means for recording digital data as a digitally encoded video signal; b) distribution means for coupling to said recording means for distributing the recorded digitally encoded video signal to end users as one of a plurality of channels; c) video signal decoding means for coupling to said distribution means for decoding the distributed recorded, digitally encoded video signal to produce an output signal representing a single user selected channel, said single user seletected channel being the one channel of said plurality of channels; d) output signal decoding means coupled to said video signal decoding means for decoding the output signal to convert the decoded, distributed and recorded, digitally encoded video signal to the digital data.
Claim 2
Independent Claim
129 words
A system for delivering digital data encoded in a video signal comprising: a) recording means for recording digital data as a digitally encoded video signal; b) distribution means for coupling to said recording means for distributing the recorded digitally encoded video signal to end users as one of a plurality of channels; c) video signal decoding means for coupling to said distribution means for decoding the distributed recorded, digitally encoded video signal to produce an output signal representing a single user selected channel, said single user seletected channel being the one channel of said plurality of channels; d) output signal decoding means coupled to said video signal decoding means for decoding the output signal to convert the decoded, distributed and recorded, digitally encoded video signal to the digital data.
Claim 3
Dependent Claim
13 words
The system defined by claim 1 wherein the digital data is audio information.
Claim 4
Dependent Claim
13 words
The system defined by claim 1 wherein the digital data is video information.
Claim 5
Dependent Claim
26 words
The system defined by claim 1 wherein the recording means is a video tape recorder capable of recording the video signal in a predetermined standardized format.
Claim 6
Dependent Claim
37 words
The system defined by claim 1 wherein the distributing means is at least one of: i) a dish-to-satellite, and a satellite-to-dish; and ii) a fiber optical cable ending in a coaxial cable in a cable subscriber's home.
Claim 7
Dependent Claim
46 words
The system defined by claim 1 wherein the video signal decoding means is a circuit which decodes a predetermined one of a plurality of signals representing information for one of a plurality of channels into a radio frequency signal adapted for use by a television receiver.
Claim 8
Dependent Claim
41 words
The system defined by claim 6 wherein the output signal decoding means is a circuit which decodes the radio frequency signal containing the digitally encoded video signal to produce a digitized signal representing the digital data encoded in the video signal.
Claim 9
Dependent Claim
22 words
The system defined by claim 7 wherein the digitized signal representing the digital data encoded in the video signal contains audio information.
Claim 10
Dependent Claim
22 words
The system defined by claim 7 wherein the digitized signal representing the digital data encoded in the video signal contains video information.
Claim 11
Dependent Claim
23 words
The system defined by claim 7 wherein the digitized signal representing the digital data encoded in the video signal contains digital graphics information.
Claim 12
Dependent Claim
44 words
The system defined by claim 7 wherein the digitized signal representing the digital data encoded in the video signal contains a real time file with multiple simultaneous sequences, wherein each said sequence includes at least one of graphics information, audio information and video information.
Claim 13
Dependent Claim
33 words
The system defined by claim 7 wherein the digitized signal representing the digital data encoded in the video signal contains digital data which is at least one of numerical data and text data.
Claim 14
Dependent Claim
29 words
The system defined by claim 7 wherein the digitized signal representing the digital data encoded in the video signal contains a real time file with multiple simultaneous graphics sequences.
