subject: Learn How Isdb-t Will Help Your Car Dvd Play Better [print this page] The modern car DVD player is a versatile machine that comes with a number of features like GPS navigation, receivers for analog TV signals and the capacity to decode various audio file formats. It can be used from almost every part of the globe and has its own method of transmitting and receiving digital signals. When trying to find out how a car DVD player actually works, we must first understand the concept of ISDB-T.
A car DVD player uses certain ways to convert incoming audio and video or other signals. It has to primarily decode the digital broadcast signal standards of the country where the player is used.
ISDB is a standard that is used for sending and receiving digital signals and was developed by the Japanese. As you might be aware, analog signal technology is fast losing its popularity and ISDB is becoming the standard of choice for decoding broadcast signals now being by radio and TV stations.
ISDB-T effectively replaces what is called MUSE or high-vision analog high definition TV (HDTV).Digital signals can convey more information in a much more efficient way than old analog signals.
To put it simply, ISDB is a method that will competently compress digital and video signals so that a large spectrum of formats like MPEG-2, MPEG-4 and JPEG can easily be read by a single device. In fact, ISDB is so flexible that it can be used with a wide range of signal modulations.
A host of countries apart from Japan and the Philippines have already started using ISDB standards for their audio and video broadcasts. They include nations like Brazil, El Salvador, Argentina, Chile, Venezuela and Peru. Many devices such as car DVD players, cell phones and laptop computers can receive and read digital signals.
The standards for digital broadcasting are different across the world. Some countries use ATSC a standard that's new to North America, which has hitherto been under NTSC while other countries fall under CVB-T.ATSC replaced NTSC in mid-2009 and is now poised to fully penetrate Mexico by 2021 and Canada in 2011.The modern devices we use today must be compatible with these standards and must have a couple of tuners to enable them to convert the signals that they receive. This makes these devices usable wherever they are manufactured or sold.
It is very easy to find out which standard the country you live in is using for digital broadcast. You just have to look for this information on the internet or look closely at the new devices that are sold in your country to determine which standards they can handle. Anyone who wants to buy a car DVD player can rest easy in the firm knowledge that most of the electronic devices manufactured today can easily and diligently read all broadcast signals, whatever be the standards they follow.
