What term refers to systems that distribute television and radio signals to a community?

The term that refers to systems distributing television and radio signals to a community is Community Antenna Television. This system, often abbreviated as CATV, involves a network of antennas that receive television signals and distribute them via coaxial or fiber-optic cables to households within a specific area. The architecture of these systems allows for multiple channels to be delivered to users, making it a staple for cable television.

On the other hand, while satellite distribution systems involve sending signals from satellites to receivers, they typically serve individual properties rather than distributing content to a community in the same way CATV does. Encoder systems are mainly involved in the preparation and compression of audio and video signals for transmission, not the actual delivery to consumers. Wireless communication systems encompass a broad range of technologies for various data transmission purposes but do not specifically focus on television and radio signal distribution to communities. Thus, Community Antenna Television is the precise term for the specified context.
