Secured high throughput data channel for public broadcast system

A method for one-way transmission of computer data over a public communication system to a subscriber who receives only said computer data, comprising the steps of:

• storing computer data that is to be broadcasted;
• broadcasting said computer data repetitively in a predetermined sequence;
• updating said computer data that is to be broadcast, said updating being made via modem connecting to a transmitter computer, said updating changing the computer data that is to be broadcast according to directions received by said modem;
• receiving only said broadcast computer data;
• demodulating said broadcast computer data;
• programming a receiver computer for selectively permitting communication of said computer data to a host computer while allowing receive-only communication with said transmitter computer from said host computer or an operator of said host computer.

A system for transmission and reception of computer data over a public broadcasting system comprising:

• A transmitter adapted to said public broadcasting system, said transmitter having a broadcasting frequency for frequency broadcasting within a bandwidth;
• a multiplexor for multiplexing said computer data into a plurality of single frequencies within said bandwidth to form a multiplexed signal, said computer data being in an original data stream prior to being multiplex;
• a modulator for modulating said transmitter with said multiplexed signal;
• a storage medium for storing data that is to be broadcasted;
• a first processor including a real time clock for controlling the flow of data to said multiplexor including a first time stamp value, said processor sending said data to said multiplexor so that each data bit modulates one of said single frequencies within said bandwidth, said first processor controlling said multiplexor so that a plurality of data streams are transmitted substantially simultaneously over said plurality of single frequencies within said bandwidth;
• a receiver tune to said broadcast frequency;
• a demodulator for demodulating said transmission to receive said plurality of single frequencies;
• filtering circuitry for tuning into each of said single frequencies and recovering said computer data;
• and
• a second processor, said second processor selecting said computer data from at least one of said single frequencies, said second processor selecting said output in response to a host computer, said second processor comparing said first time stamp value to a second time stamp value for determining whether said host computer has access to said computer data from at least one of said single frequencies.

A method for one way transmission of video game computer data to a subscriber who receives only said video game computer data, comprising the steps of:

• including a menu within said video game computer data with said one-way transmission of video game computer data, said menu indicating each of a plurality of video games included in said video game computer data;
• modulating a transmitter adapted for broadcasting with said video game computer data containing said plurality of video games, said transmitter broadcasting all games continuously and repetitively in a predetermined sequence;
• demodulating said transmitted video game computer data containing said menu after reception of said data by a receiver controlled by a microprocessor;
• selecting a specific video game from said plurality of video games from said menu in response to input controls of a video game player which video game player transmits selection control signals to said microprocessor, said microprocessor being programmed independently from said video game player to selectively allow or deny access to said plurality of video games by said video game player;
• receiving and then demodulating said transmitted computer data to search for said specific video game;
• and
• detecting said specific video game.
