wats the deal with these new dvd players?

Question

like hi-def dvd players and blutooth dvd players a hi-definition dvds wats the deal?

Answer 1

High definition DVD players will play HD-DVD or Blu-Ray DVD movies, which are recorded in 720p or 1080i or 1080p format. This means higher resolution, clearer picture and better movie experience.

The more traditional DVD players will play standard DVD's, which output at 480p.

Upconverting DVD players will play standard DVD's and scale the movies to 720p or 1080i. Quasi-high def. It's more marketing hype.

Side note, it takes approximately 10GB for an hour of high definition video. Original DVD's only store up to 8.4GB, where the high definition DVD's can store more than 50GB. Hence the need for a new format like HD-DVD or Blu-Ray, in order to support high def movies.

Answer 2

Normal DVDs hold about 4.5 Gigabytes of data. therefore, to fit the whole movie and several different sound options on the DVD, all of the stuff has to be compressed. When you compress stuff, you lose quality.

the new players such as HD-DVD and Blu-Ray use a new technology with a blue laser. Because the wavelength of the blue laser is shorter and more fine, they can put more data on a DVD. This way, uncompressed audio and video can be put on a DVD and is transferred purely digitally to your tv for AMAZING quality.

unfortunately, to get this quality you have to spend quite a bit of money right now. they will eventually drop in price, as all good electronics do. The new players will play your old dvd's though, if you were wondering. You also have to start buying HD-DVD's to take advantage of the quality (or blu-ray), and they cost more money too.

Hope this helps.
