Television technology has made startling advances within the last decade. Broadcast television signals have made the switch from analog to digital, affecting how our sets receive and process the signal.
Who Is the ATSC?
The Advanced Television Standards Committee is a group of technology companies and organizations that work together to create standards for television technology. This ensures that all the equipment will work together and we won't need a different television for each channel.
What Is an ATSC Tuner?
An ATSC tuner is a device that is designed to receive and decode broadcast Digital Televesion Video (DTV) signals. This includes standard definition and high-definition (HDTV) signals.
What Are Built-in ATSC Tuners?
Beginning back on March 1, 2007, all televisions shipped between states or imported into the United States were required by the Federal Communications Commission to contain an ATSC tuner. Starting on May 25, 2007, all televisions that were still in store stock that didn't have an ATSC tuner were required to be labeled as such.
Why Is an ATSC Tuner Necessary?
Beginning on June 12, 2009, all full-power broadcast television stations were required to turn off their analog transmitters and switch to a digital-only signal.
What Are the Advantages to You?
If you have an HDTV, you can get free HDTV programming. Since a digital signal is more efficient at transmitting data, you can get broadcast television in high definition without having to subscribe to a cable or satellite service.
