Receiver card technology for a broadcast subscription video service
First Claim
1. A method for processing broadcast subscription video programming, comprising:
- receiving, in a plug-in card, subscription video programming in a micro analog tuner/demodulator;
separating, within the plug-in card, an unused portion of the subscription video programming to extract encoded proprietary programming in a vertical blanking interval device;
controlling, within the plug-in card, user access to the encoded proprietary programming using conditional access/decryption technology;
decompressing, within the plug-in card, video and audio data from the encoded proprietary programming using decompression technology;
encoding, within the plug-in card, the video and audio data to provide the video and audio data in a desired protocol;
controlling, within the plug-in card, video programming properties; and
storing video programming information in memory on the plug-in card.

Abstract
An integrated plug-in card is configured to process subscription video programming. The card consists of multiple integrated technologies. A micro analog tuner/demodulator receives the subscription video programming and provides output to a vertical blanking interval (VBI) device. The vertical blanking interface device separates an unused portion of the subscription video programming to extract an encoded proprietary programming. Conditional access/decryption technology controls user access to the encoded proprietary programming. Video and audio decompression technology decompresses video and audio data from the encoded proprietary programming. An encoder provides the video and audio data in a desired protocol. A control interface controls video programming properties and a memory is utilized for storing video programming information.
