What is the integrated ATSC?

Standard National Television System Committee (NTSC) for analog TV signaling, adopted by the Federal Communication Commission (FCC) in 1941, remained on the spot until 2009. Due to the difference in the DTV signals, the ATSC requires a tuner capable of decoding its signals at the end of the transmission. To facilitate this process, they have television files and television devices such as digital video call players (DVDs) and digital video recorders (DVR), integrated ATSC. Any device involving integrated ATSC has an ATSC tuner built into its hardware.

Before a device like a high -resolution television (HDTV), the DTV telecommunications company's signaling can display operations. When the DTV signals are sent, they are compressed by the source. After reaching the goal, these signals must be decompressed, demultiplexed, demodulated and OPRaveny errors. Each of these processes, along with several other digital tuner duties.

DTV signals are compressed into smaller data packets for easier transport either in the air or other media, such as a coaxial cable and must therefore be decompressed as soon as they reach their goal. Because these signals are combined in a surgery called multiplexing and transported by means of a transport current (MPEG), they must also be demultiplexed. Demodulation occurs when the tuner transforms the transmitted signal into a signal usable on television and error correction is the accounting process of any missing data in the current. Another ATSC work is to choose the right radiofrequency channel.

For owners of older television (TV) sets, especially those produced before 2007, the transition to DTV was a problem when the NTSC standard was abandoned. Since 2007, all TV sets and interfaces must beEquipment with integrated ATSC tuner. Older TVs do not have a way to perform the necessary operations to display DTV signals, and at the time of switching to ATSC in 2009, consumers with older TV sets faced a need to buy a new television with an integrated ATSC or external converter. For this reason, coupons have been issued that compensate for consumer costs when buying one of these set-top boxes.

Like the ATSC tuner, the tuner is a quadratural amplitude modulation (QAM). QAM is standard outside ATSC and is generally used by cable TV operators. Unlike the integrated ATSC, QAM tuners are usually integrated into a set-top box provided by cable companies, though some HDTV sets also have integrated QAM tuners.
