RF modulator - Wikipedia

RF modulators operate on different channels depending on the region and have been integrated into various home electronics. However, they tend to produce lower image quality than a baseband connection due to losses during the modulation and demodulation process. In professional broadcast settings, more sophisticated modulators are used. Prior to the introduction of specialised video connector standards such as SCART or RCA connectors, TVs were designed to only accept signals through the aerial connector: signals originate at a TV station, are transmitted over the air, and are then received by an antenna and demodulated within the TV. Since later television designs include composite, S-Video, and component video jacks, which skip the modulation and demodulation steps, modulators are no longer included as standard equipment, and RF modulators are now largely a third-party product, purchased primarily to run newer equipment such as DVD players with an old television set. RF modulation puts the desired information on to a carrier signal at a standardized frequency. Amplitude or frequency modulation may be used, as required by the receiving equipment. Modulating a TV signal with stereo sound is relatively complex; most low-cost home TV modulators produce a signal with monaural audio. With other channels being used for RF modulation function in other regions, channel 3/4 output is a misnomer for those regions. Recently, some RF demodulators have been marketed on obscure online markets to allow channel 3 inputs from legacy devices to work on RCA composite in. When equipment was developed which could use a television receiver as its display device, such as VCRs, DVD players, early home computers, and video game consoles, the signal was modulated and sent to the RF input connector. The aerial connector whether it is 300-ohm or 75-ohm is standard on all TV sets, even very old ones. TV modulators generally feature analog passthrough, meaning that they take input both from the device and from the usual antenna input, and the antenna input "passes through" to the TV, with minor insertion loss due to the added device. In some cases the antenna input is always passed through, while in other cases the antenna input is turned off when the device is outputting a signal, and only the device signal is sent onward, to reduce interference. RF modulators produce a relatively poor picture, as image quality is lost during both the modulation from the source device, and the demodulation in the television.
