Abstract

The following describes a system for connecting satellite receivers to a network built using the existing home satellite cable infrastructure. Existing satellite receivers are connected to coaxial wire which leads to dish antenna. When multiple receivers or dishes are used, an LMB switch must be used. Sometimes this switch is even integrated into the head of the dish. Because all receivers are wired via coax to the same switch, this point can serve as the hub to a network. By multiplexing singals over the coax, both network and satellite signals can be carried on the same wire. This allows multiple receivers to communicate with each other without any additional wiring in the home. Such communication could include the issuing of instructions to record a given event, or accessing a previously recorded event.

Enhanced In-Home Satellite System Infrastructure for Local Area Network

Many home satellite subscribers have a satellite receiver with recording capability. This recorded content can only be played back using that receiver. The receiver is often hooked up to every television in the house, meaning that only one recorded show can be viewed at any time. Satellite providers offer additional receivers to customers, but there are drawbacks to having multiple receivers. Content recorded on one receiver cannot be viewed on another. If two shows should be recorded simultaneously, a receiver with recording capability MUST have two built in tuners. Currently, there is no attractive system besides a single, multiple-tuner receiver which is hooked up to every television in the home. Current home installations look like this:

This invention would allow multiple receivers within the home to communicate with each other over a network. Instead of having two built-in tuners, a receiver might record one show and simultaneously ask another receiver to record a second show. Any recorded show could be played back using any receiver by transmitting the show over the network. This makes buying additional receiver much more attractive to the customer, which results in more subscription fees for the provider. Also, single-tuner recorders have a lower price point and would now have upgrade potential.

Using the existing coaxial cables which connect the receivers to the LMB switch, network t...
