Curiousity – HDDVD vs Blu-Ray

[Shane Ross]

HD DVD…35GB on a disk.

BluRay…50GB on a disk.

Apparently the copy protection is better on BluRay, which is why Hollywood went that way. But Sony’s licensing for that format is pricy.

I have an HD DVD player and love it. Upscales regular DVDs fine, and I can burn disks in DVD SP that work on it right away. But only my machine, and any XBOX-360 (those are HD DVD based).

hmm…interesting. seems weird that there was even a “war.” why would you only want 35GB or less copy protection?

oh well…i was rooting for blu-ray anyway.

thanks

Copy protection is a bit of a waste of time. It gets in the way of legit use and doesn’t worry the pirates.

The real issue for me is not the storage size of HD DVD as multi layering technology means that five layer disks are feasible so 100 + gig storage on HD DVD was almost available when they pulled the pin.

The real issue is the much higher install costs for mass duplicators. Bluray is much more expensive. The other great cost is the high reject rate on Bluray disks. So the ability to make money off the format is in the short term difficult until reject rates are as low as HD DVDs were. The world is moving on anyway so HD DVD/ Bluray are limited commercial options. Meanwhile really cheap multi layer red laser disks are likely to become available to archive 100+ gig material.

First off, the ONLY 2 advantages BD has/had over HD DVD was the extra 10mb/s bandwidth for video and the extra 10g per layer. At these bitrates, the eye will not see a difference! As someone mentioned, multi-layered discs were easily being manufactured as they pulled the plug.

HD DVD had a 15G single capacity and 30G DL capacity. Blu Ray is 25/50. Both support the same copy protection but HD DVD was not mandatory like it is on BD. BD+ is another copy protection offered by BD but as also been cracked as well.

HD DVD had 2 flavors – Advanced Content – pop-up menus using a language called HDi and Standard Content – exactly like DVD but with HD content. Video Bitrates were limted to 30mb/s

Blu Ray also has 2 flavors – HDMV with pop up menus and BD-J. Basically BD-J is Java so you’re only limited to your imagination and the power of the playback device 🙂 Video Bitrates were limted to 40mb/s.

HD DVD was far superior to Blu Ray in so many ways – don’t anyone tell you different. It was cheap, no licensing involved, replication used current manufacturing lines. So sad really…if HD DVD survived no one here would be complaining about delivery HD on disc to clients – which leaves my wondering why anyone in this forum would have been rooting for BD. Basically, you were screwed last year beyond belief – the Man wins again!

Blu-Ray is more fun to say than HDDVD. That’s why it won:)
