what is the difference between hd dvd and blu-ray dvd?

Answer 1

Remember VHS vs Betamax? What that format war has taught us is that it doesn't matter if the format is technologically better. Betamax was technologically better than VHS but it still lost. That format war did teach us that content decides the victor. There were more movie studios backing VHS than Betamax, therefore more people bought VHS movies. In today's format war, whether you look at it from technical point of view or content point of view, Blu-ray is the winner. We all know that Blu-ray is the technologically superior of the two, i.e. more storage space, and if you do some research you'll see that Blu-ray has more movie studios that are exclusive to Blu-ray, whereas HD-DVD has only one. Blu-ray is outselling HD-DVD almost 3 to 1, and it hasn't lost momentum. It is only a matter of time before the war is over.

Blu-ray All the Way!!!

Answer 2

properly Toshiba backed HD-DVD while Sony backs up Blu-Ray. be conscious that I used previous demanding for HD-DVD. that's reason HD-DVD is basically non-existent. there replaced into for a on a similar time as what replaced into referred to as the format wars. Sony gained, subsequently Blu-Ray format is the only severe definition format available now. in my opinion i could've wished HD-DVD to win by way of fact people could be at a loss for words between Blu-Ray & DVD greater effective than they could between HD-DVD & DVD.

Answer 3

Blu-Ray has a higher capacity but uses an old DVD format.

HD-DVD has enough for the movie and some features but uses a new format that can be very beneficial in the future

Blu Ray sucks btw, its blue and Sony...

Sony has never won a format war

Answer 4

Leaving all of the technical nonsense aside. HD-DVD's play on HD-DVD Players, and BluRay discs play on Bluray players.

Some of the discs will have features that will only be used by a certain format.

So ya :|. If I we're you I would just wait awhile before deciding on what format of movies you want to side with.

Answer 5

Technical mumbo-jumbo: The primary rival to Blu-ray Disc is HD DVD, championed by Toshiba, NEC Corporation, Microsoft, and Intel. HD DVD has a lower theoretical disc capacity per layer (15 GB vs 25 GB). However the majority (over 80%[29]) of Blu-ray titles are in 25 GB single layer format while almost all (over 90%[30]) HD DVD movies are in 30 GB dual layer format. The Blu-ray Disc version of the Adam Sandler movie Click was released on October 10, 2006 as the first ever dual-layer release. Sony's goal is to use 50 GB dual-layer discs to store up to nine hours of HD video content. Alternatively, studios releasing movies on Blu-ray Disc can choose to use VC-1 or H.264/AVC instead of MPEG-2 as an alternative way to put four hours of high-definition content on a (single layer) BD.

Alternatively: The primary rival to HD DVD is Blu-ray, championed by Sony. Blu-ray has a higher disc capacity per layer (25 GB vs 15 GB). However the majority (over 80%[32]) of Blu-ray titles are in 25 GB single layer format while almost all (over 90%[33]) HD DVD movies are in 30 GB dual layer format.
In terms of audio/video compression, HD DVD and Blu-ray are similar on the surface: both support MPEG-2, VC-1, and H.264 for video compression. Virtually every HD DVD released uses an advanced codec (VC-1 or H.264) for video compression, reducing the required space for equivalent quality video. The first generation of Blu-ray Disc movies however used the legacy video codec MPEG-2, and many new titles still do. In terms of audio, there are many differences. With HD DVD support for the new Dolby Digital Plus audio codec is mandatory at a maximum of 3.0 Mbit/s, but for Blu-ray players it is optional at a maximum of 1.7 Mbit/s.[34] Furthermore HD DVD players must be able to decode the new lossless audio codec Dolby True HD, but this is optional for Blu-ray players.
Both HD DVD and Blu-ray Disc support the 24p (traditional movie) frame rate, but technical implementations of this mode are different among the two formats. Blu-ray Disc supports 24p with its native timing, while HD DVD uses 60i timing for 24p (encoded progressively, replacing missing fields with "repeat field flags"). Decoders can ignore the “flags” to output 24p.[35] There is no impact on picture resolution or storage space as a result of this, as the HD DVD format uses the exact same video information — it simply adds notational overhead.


In English: Not a damn thing worth mentioning. It's another format war like vhs and betamax. This time however, nobody cares. >.> Normal dvds work just fine. HD is overrated and ridiculously expensive.
