Tv transmissions will change to HD at the end of the year, are they doing the same to radio?
walkerzo2000 asked:
If they are changing to digital transmission for radio, will there be simulcast of analog and digital since most don’t want to pop the cash for new radio?

first of all, it will not change to hd for another 20 years, giving ppl enough time to buy a hd ready tv or buy a hd receiver, there is no plan for radio since the quality isnt really worth it. audio quality really wouldnt improve very much
The change is TO DIGITAL **not** HD.
The new system in the US is more commonly ATSC and is 100% digital unlike the present NTSC system which is analog.
Europe chose to use a BETTER system for the digital TV called DVB-T which is similar to the DVB-S system used by Dish Network.
An OPTION of the ATSC system is to send:
1) Upto 4 SD or normal streams
2) 1 HD channel in 1080p
3)
Pending no more extensions broadcasters have till 2009 to switch formats and clear the frequencies.
Those using antennas to get their TV will need to get a converter box to connect to their existing TV or get a new TV. Those on other forms like DBS (dish) or cable may not need a converter but may need a new TV to display HD if your interested.
I personally have seend HD, and I am NOT impressed. Much hype about nothing.
There ARE future plans to convert the FM band to a form of digital in the future as well. Its called HD FD radio from iBuquity. This actually will be an analog and digital compatiable signal. Theres a few test sites right now.
It’s in progress. There are a few radio stations already transmitting digital. It’s being called HD radio by a lot of people. Another term is IBOC for in band on channel. See the link below.
