  • Patent number: 7555768
    Abstract: A transmission spectrum historically associated with analog broadcast signals is leveraged for digital transmission to provide broadcast channels and user-requested channels to a specific geographic region. In addition to broadcast data such as television programming, digital newspapers, and movie channels, back-channels are used to provide interactive and bi-directional communications necessary for on-demand content, internet access, video games, telephone services, and the like. The back-channels may be transmitted via wireless, telephone modem, DSL, or other means. The broadcast license associated with the present invention may be a commercial broadcast license, a public service license, a low power license, or the like. To increase the available channels and associated services, the original analog signal may be replaced by digital transmission signals.
