Analog television signal data delivery system
First Claim
1. A process for creating and transmitting television broadcast signals carrying data for client systems, comprising the steps of:
- providing means for creating a data show;
wherein said creating means modulates binary data intended for client systems in each frame of said data show;
wherein each entire frame is used to modulate the data;
broadcasting said data show using television broadcast signals; and
receiving said data show on a plurality of client systems.

Abstract
An analog television signal data delivery system provides a television program, called a data show, that is transmitted across standard television broadcast methods to data needy client systems, such as settop boxes, at certain times of the day. When the data show is recorded and specially demodulated it provides the client system with raw digital data to perform required or enhanced functions. Binary digital data is modulated into each frame of the data show. Each of the 480 scan lines in a frame have data modulated into it. Each scan line in the frame contains two bytes which yields 28800 bytes/sec. This high transfer rate results in an efficient data transfer method that is cost effective and easily broadcast. Another preferred embodiment of the invention designates some regions of the active video picture to contain visible images and other regions of the active picture to contain data. The non-data portions can be placed anywhere on the viewable frame. The client system receiver knows the channel, time, and duration that the data show is being broadcast. At the data show time, the client system records the data show on its local storage device and demodulates and decodes the data show at a later time or demodulates and/or decodes the data show on the fly. Once demodulated and/or decoded, the data are used as intended.
