Actually, Blu-Rays won the battle of the formats when HD content was introduced to discs. HD-DVD was a competing format but when it became apparent that content producers and publishers were supporting Bluray rather than HD-DVD, the latter was soon withdrawn.
Technically, there was little different between the quality and data storage capacities of the discs.
Bluray is the disc format developed by Sony for HD video content. It is not a television format and only refers to the storage medium. All Bluray disc players need a display and it may be plasma, LDC or LED based. It is therefore impossible to compare Bluray to types of TV.
Blu-ray or Blu-ray Disc is a digital optical disc data storage format. It was designed to supersede the DVD format, and is capable of storing several hours of video in high-definition.
A Bluray disc stores five times more data than a DVD. Therefore, a DVD will not have the capacity to store the contents of a Bluray disc.
No
There are three storage formats for video discs: A DVD will carry standard definition video and will be described simply as "DVD". DVDs can be played on standard definition DVD players as well as either of the HD disc players mentioned below. Regardless of the player used, the image will always be standard definition. HD DVD is one of the two HD disc formats. The disc will be described as an "HD DVD". This format was withdrawn in 2009 when Bluray won the HD format war. HD DVD players and discs are still around but none are sold commercially now. These discs can only be played on HD DVD players. Bluray is the other HD video disc format. They will always be described as "Bluray". They can only be played on Bluray players and will not operate on standard DVD players. Nor will they play on an HD DVD player. Note: HD DVD is the product trade name of the now defunct high definition disc format. It is also commonly used in reference to an disc that supports high definition video. Therefore, is it sometimes used as a reference to Bluray. Although Bluray is a high definition DVD, it is NOT an "HD DVD". As the HD DVD format moves into the history books of television, the term is used more and more to refer to Buray even though it is strictly not the correct term.
The introduction of high definition discs saw two formats launched. Bluray is one and HD DVD was the other. The format war was won by the Bluray system and HD DVD was withdrawn in 2009. Both Bluray and HD DVD are high definition players but note that "HD DVD" is the name of the format and is confusingly close to the generic description of high definition disc players. Bluray and HD DVD are not compatible so a disc of one type will not play on the other format. There are a handful of dual format disc players but they were expensive and few were sold. If you have HD DVD discs then you need to hand on to an HD DVD player if you want to watch them. All high definition discs on sale now are Bluray and of course will need a Bluray player to play them.
BluRay discs carry high definition television and therefore store data in a high density format. A standard definition DVD player will not recognise a BluRay disc and will simply report an error if one is loaded. On the other hand, a BluRay player will not only play BluRay discs but will also handle standard DVDs. Most will also recognise and play CD format discs. Most Bluray players will also down convert the HD signal from a BluRay disc so that it can be viewed on a standard definition television. In this case, of course, the image quality will be the same as any other standard definition signal. To benefit from the high definition signal, an HD television is also required.
Bluray
yes, but you wont get high definition quality
ps3 games are bluray disc
To play a high definition DVD, you need a high definition DVD player. There are two types available currently. HD DVD, developed by Toshiba is one and BluRay, developed by Sony is the other. They are not compatible, so an HD DVD will not play on a BluRay player and a BluRay disc will not play on an HD DVD player. BluRay looks like it is the winner in the format war between the two companies over the last years so it is likely that Toshiba's format will disappear in the coming months. Note that HD DVD can refer to the Toshiba format but it can also refer to high definition DVDs in general.
A blu ray disc is a storage medium, not an input/output device.
