The Transition to DTV
In the United States, the FCC's DTV rollout schedule set deadlines for stations to complete the DTV transition process. Commercial television stations were supposed to have completed construction of DTV facilities by May 1, 2002. Public television stations were supposed to have completed their DTV facilities by May 1, 2003. Of course, extensions were granted based on individual circumstances. Once a station is DTV ready, that station may broadcast DTV programming. The FCC's schedule for transition to DTV originally proposed that everyone in the U.S. should have access to DTV by 2002, although analog transmissions continued after that date. After the switch to digital has been completed, regular television sets will need converters to receive broadcasts, although their sets will remain functional indefinitely. Actions are being taken to make the transition as smooth as possible. For example, in the Telecommunications Act of 1996, the FCC allotted to each existing broadcaster an additional 6MHz channel for digital transmissions, so that they could send out both analog and digital transmissions simultaneously. This procedure is known as simulcasting. The FCC mandated that all analog transmission would cease in 2009.

After the switch to digital has been completed,โทรทัศน์ปกติจะต้องแปลงได้รับการออกอากาศ แม้ว่าชุดของพวกเขาจะยังคงทำงานไปเรื่อย ๆ การกระทำที่ถูกจับให้เปลี่ยนเป็นเรียบที่สุดเท่าที่จะทำได้ ตัวอย่างเช่น ในกิจการโทรคมนาคม Act of 1996 FCC จัดสรรให้กับแต่ละช่องทางที่มีอยู่ โฆษก 6mhz เพิ่มเติมสำหรับการส่งแบบดิจิตอลเพื่อให้พวกเขาสามารถส่งทั้งแบบอนาล็อกและดิจิตอล ส่งพร้อมกัน ขั้นตอนนี้จะเรียกว่า simulcasting . FCC บังคับว่า ทุกคนจะหยุดการส่งแบบอนาล็อก
