Therefore, error correction has the opposite effect of compression-it increases the amount of data to transmit, rather than reducing it like compression does, and it improves the quality and robustness of the signal rather than reducing it. Error correction works by adding some extra information to the signal before transmission that can be used upon reception to fill in gaps. With error correction, the tuner has the ability to perform a number of checks and repair data so that a signal can be viewed on a TV set. For instance, sometimes interference or a poor-quality signal will cause the loss of some data that the ATSC tuner receives. Error correction Д®rror correction is a technology that is used by the ATSC tuner to make sure that any data that is missing can be corrected. The ATSC system uses lossy compression, so while the decompressed data size is the same as the original compressed data size, the data produced is not exactly the same as the original data fed into the system at the transmitting site, but it is close enough that most people will not notice a difference. Since digital signals that are broadcast over the air are compressed (packed smaller), once they are received by the ATSC tuner, these compressed packets of digital data are then decompressed (unpacked to their original size). By the reverse process ( demultiplexing), an ATSC receiver first receives the combined MPEG transport stream and then decodes it to display one of its component signals on a TV set. In the US, multiple digital signals are combined and then transmitted from one antenna source to create over the air broadcasts. It is separation of a standard baseband signal from the RF carrier that was used to transmit it through the air (or down a coaxial cable or other long-distance medium.) ATSC as implemented in the US uses 8VSB modulation, which requires less power to transmit, as opposed to the also proposed COFDM modulation (used in European DVB-T, which is less prone to multipath distortion and therefore better received in mobile installations). 'Demodulation' means transforming the signal from the tuner into a signal that a TV set can use to produce images and sound without further consideration for the frequency at which it was transmitted. The tuner usually performs the function of frequency-agile selection, along with rejection of unwanted out-of-band signals. Selective tuning is the process by which the radio frequency (RF) of the television channel is selected by a receiver from within a band of transmitted RF signals. ATSC tuners provide the following functions: selective tuning demodulation transport stream demultiplexing decompression error correction analog-to-digital conversion AV synchronization and media reformatting to fit the specific type of TV screen optimally. Operation ДЄn ATSC tuner works by generating audio and video signals that are picked up from over-the-air broadcast television. Some ATSC receivers, mostly those in HDTV TV sets, will stretch automatically, either by detecting black bars or by reading the Active Format Descriptor (AFD).

This lets the user eliminate letterboxing or pillarboxing by stretching or cropping the picture. It is commonly used to convert a low-resolution picture to a high-resolution display. Zooming is an example of resolution change. Examples of media reformatting include: interlace to progressive scan or vice versa picture resolutions aspect ratio conversions (16:9 to or from 4:3) frame rate conversion and image scaling.

The receiver generates the audio and video (AV) signals needed for television, and performs the following tasks: demodulation error correction MPEG transport stream demultiplexing decompression AV synchronization and media reformatting to match what is optimal input for one's TV.

The terms 'tuner' and 'receiver' are used loosely, and it is perhaps more appropriately called an ATSC receiver, with the tuner being part of the receiver (see Metonymy).
