[17/03/2010] Mysteries about Car DVD Player
Portable DVD players are the future of portable entertaining. Mainly because you don't have to take with you wherever you go only a radio or mp3 player. You can take everything now combined in one, plus great quality DVD Player.
There is also something which will change the future even more... it is DVB-T. This term specifies Digital Broadcasting Terrestrial. It is a new industry standard developed in Europe which will allow to broadcast TV in different way than before.
It allows stream audio and video in MPEG transport system. Many car DVD players and other devices that are designed to receive and then play digital audio and video come equipped with DVB-T.
There are several other different digital television and digital broadcasting standards that exist, with many countries allowing for the manufacture and distribution of car DVD players and other devices that feature not only those tuners but also DVB-T. North American players and devices go with what is known as ATSC.
Simply put, DVB-T is different in the way it carries all that data over the air. Many other methods will do so through use of a single radio frequency, while DVB-T does so by splitting all of that data into a very large number of slower digital information streams and then reassembling them at the point of receipt.
There are three different standards for DVB-T, so it is good to know which standard a player is operating because it could be important because two of those standards are more recent and equipment making use of older-standard players may not work or interface at all with the newer standard players.
A car DVD player equipped with digital video broadcast capability is all about compression rate, in other words, how fast it can squeeze and then decode signals coming from a broadcast source, which will also impact the quality of any pictures displayed.
It is easy enough to figure out the digital video broadcast standard for any country by going online and then pulling up a DVB-T map or looking at the product box, which will clearly highlight the tuners for countries where the player did the job.
