Digital TV Transition Underway
By Avery Parker
As many of us that live in the United States have already heard, our broadcast television stations are switching to all digital broadcasting. The original deadline for full power analog broadcasts to end was February 17 at midnight, but there was legislation passed to postpone the deadline until June 12th. So what does this all mean? It means that if you receive any television programming via an antenna you will either need a television that is digital ready, or a digital converter box to continue to receive those free, local, over the air signals. If you keep an antenna based tv only for cable and satellite tv outages for local news and information those too will need to be checked to make sure you have the equipment to get the new digital signals. Most stations that are going to be switching to digital have already been broadcasting in digital (and the old analog) for some time as they've tested their new equipment. Given the new deadline, some stations have already discontinued the old analog signal and other stations may do so at any time with proper notice to the FCC and public before the June 12th deadline. One interesting exception to the digital transition is that for low power stations. These lower power stations are under no obligation to switch to digital. In many cases these may be analog repeaters (a device used to take a signal and rebroadcast it.) The analog repeaters often times serve remote areas. PBS in North Carolina for instance has many small low power repeaters that will not be effected by the transition to digital. The transition to digital broadcasting can give many benefits. The biggest benefit from a public policy standpoint is that the digital signals take up less bandwidth in the airwaves than analog. This means that using the same frequencies you can get more information broadcast. What this will do is open up frequencies for other uses such as emergency communications. |
