The broadcast source is the way you receive your television signal. Beyond TV 3.5 supports various broadcast sources. See the document Connecting Broadcast Source for information on configuring Beyond TV with the broadcast source option you're using.
Antenna
This is the traditional source for receiving a television signal. A coaxial cable runs from a nearby antenna and connects directly to the coaxial input (video in) on your television. This broadcast source does not involve a service provider.
Cable (Analog)
A cable television provider runs a coaxial cable into your home that carries a television signal. The coaxial cable connects directly to the coaxial input (video in) on your television. Your channel lineup depends on the tier of channels included in the package you've purchased.
Cable (Digital)
A cable television provider runs a coaxial cable into your home that connects to an external receiver box that decodes the provider's signal. This receiver box connects to your television and presents the channels available in the package you've purchased.
Satellite
A provider installs a local satellite dish that receives a television signal. This signal is carried via a coaxial cable connected to an external receiver box. This receiver box connects to your television and presents the channels available in the package you've purchased.
