Television receive-only

The term Television receive-only, or TVRO, arose during the IRFZ46N early days of satellite television reception to differentiate it from commercial satellite television uplink and downlink operations (transmit and receive). This was before there was a DTH satellite television broadcast industry. Satellite television channels at that IRF640 time were intended to be used by cable television networks rather than received by home viewers. Satellite TV receiver systems were largely constructed by hobbyists and engineers. In 1978 Microcomm, a small company founded by radio amateur and microwave engineer H. Paul Shuch, ICL7660 introduced the first commercial home satellite TV receiver. These early TVRO systems operated mainly on the C band frequencies and the dishes required were large; typically over 3 meters in diameter. Consequently TVRO is often referred to as big dish or Big Ugly Dish (BUD) satellite television.TVRO systems MC145151 are designed to receive analog and digital satellite feeds of both television or audio from both C-band and Ku-band transponders on FSS-type satellites. The higher frequency Ku-band systems tend to be Direct To Home systems and can use a smaller dish antenna because of the higher power transmissions and greater antenna gain.TVRO AD7776 systems tend to use larger rather than smaller satellite dish antennas, since it is more likely that the owner of a TVRO system would have a C-band-only setup rather than a Ku band-only setup. Additional receiver boxes allow for different types of digital satellite signal reception, such as DVB/MPEG-2 and 4DTV.
