What is ATSC Tuner?
The Advanced Television Systems Committee is the name of the stations that use the digital television system. An ATSC tuner or HDTV tuner receives digital television signals broadcasted by these stations and allows viewers to watch programs on their television sets.
An ATSC tuner receives signals from over-the-air television broadcasts. In order to convert the signals to fit the television screen, it uses one or more of the following functions: analog-to-digital conversion, audio / video synchronization, decompression, demodulation, error correction, reformatting or demultiplexing means transport flow.
ATSC tuners can be built in different electronics. They can come directly inside a TV box, DVR, VCR or DTV. Televisions with ATSC tuners will need a TV antenna system, while DVRs, VCRs and DTVs all act as decoders to receive signals from the channels.
The United States government requires that all televisions built after March 1, 2007 include an ATSC tuner, since all television operators must now broadcast only digital signals on all receiving televisions. Owners of television can still use decoders, but that will not have any additional impact on image quality.
An “ATSC tuner” is the technical name of a digital tuner. ATSC stands for Advanced Television System Committee, which is the committee responsible for creating the standards used to transmit and receive digital television signals in the United States. In order to watch broadcast television, you must have either a set-top box or a television equipped with an internal Advanced Television Systems tuner that decode digital TV signals. ATSC tuners must be programmed before they can be monitored.
Connecting an external Advanced Television Systems tuner to an analog TV
Connect the output of the ATSC tuner box to the corresponding input on the TV. ATSC tuners generally have two output options — RF and AV. Therefore, it is possible to use a coaxial cable or a set of AV cables to make this connection. When using AV cables, remember to insert each AV plug to the AV jack corresponding to its color.
- Connect the coaxial cable from the TV antenna to the ATSC tuner “RF In” terminal, named with the letter “Antenna In”.
- Connect the ATSC tuner to a power source.
- Turn on the TV and the Advanced Television Systems tuner.
- Tune the TV to channel 3 if you have used a coaxial cable. Set the video input channel of the TV to the AV source if you used an AV cable set.
