1. A method for generating video output based on data received from a cable input comprising the steps of:
- receiving said cable input in an access module;
demodulating and providing conditional access to at least some of said cable input in said access module;
transferring said at least some of said cable input from said access module to a media processing module;
receiving computer-generated graphics in said media processing module; and
mixing said at least some of said cable input and said computer-generated graphics in said media processing module to generate said video output.

5. A computer video system comprising:
-
an access module for receiving a cable input, demodulating said cable input and extracting data streams associated with a customer access from said demodulated cable input;
an interconnect for transferring said extracted data streams to a media processor module;
wherein said media processor module also receives computer-generated graphics and mixes said extracted data streams with said computer-generated graphics to generate a video output stream. - View Dependent Claims (6)

7. A cable data processing system comprising:
-
a first module, inaccessible by a general processor associated with a computer, including privileged application program interfaces (APIs) for operating on an incoming cable data stream; and
a second module, accessible by said general processor associated with said computer, including safe APIs for operating on said incoming cable data stream. - View Dependent Claims (8, 9)

10. A cable data input card for a computer comprising:
-
an RF input capable of receiving a coaxial cable that conveys cable data to said cable data input card;
a PCMCIA slot having a PCMCIA card inserted therein, said PCMCIA card including a conditional access function for selectively allowing access to data streams within said cable data; and
an output which outputs those of said data streams authorized by said conditional access function to a secure interconnect.
