Mitsubishi SR-HD5 HD DIRECTV Plus Receiver

The Broadcasting and Receiving network

How Does All This Work?

First, here is some information about your HD receiver. Your HD receiver can receive three types of television signals:

●Analog signals in NTSC (National Television Systems Committee—traditional TV sig- nals) format—from terrestrial, or broadcasting towers built on earth, and cable sources.

●Digital signals in ATSC (Advanced Television Systems Committee—digital TV signals) format—from terrestrial sources.

●Digital Satellite signals—from DIRECTV satellites in space. These signals can be either Standard Definition (SD) signals or High Definition (HD) signals.

Second, here is some information about the broadcasting and receiving network shown.

Television stations, film studios, and other broadcasters send signals to earthbound terrestrial broadcasting towers and satellites. The tower shown on the right is sending Digital ATSC format signals and the more traditional Analog NTSC format signals. Both ATSC and NTSC signals can be received by the same VHF/UHF antenna normally mounted on a roof or in an attic. The satellites shown are sending DIRECTV programming signals which are received by a DIRECTV PLUS™ Satellite Dish Antenna usually mounted on a roof or on the ground. These satellites are located in geostationary orbit. Cable television signals are received through cables installed by cable television providers. The terrestrial broadcast (from a tower), satellite, and cable signals then go into your HD receiver where they are processed and sent to your television set.
