The precursor of BD. Many HD cams use this.
I have to hand it to Sony, it IS clever. The DVcam uses 2 (!) pickups to write to the disc for high speed, or one can be used for data verification on the fly. I really think THIS is why Sony pushed BD so hard. They had a lot at stake.

The annoying part is that the BDA likes to advertise how their Blu-ray Discs have a scratch resistant coating and HD DVD does not. Yes, true, but like Dave said, it's only half the story. HD DVD doesn't need it!
FYI: The BDA *had* to add the coating. Theres no way in hell they could have even competed with HD DVD if their discs required a caddy system. The caddy system costs a hell of a lot more than a coating and market research showed that the general public did not want anything with caddies. For it succeed, the disc had to look just like a DVD, which itself had to look just like a CD...

Dave
Yes I did read your whole post.
I was just wondering how good (with this scratch resistant coating) they held up. CD's and DVD's go through hell nowadays, I can usually fix some of them just by polishing out some of the scratches, if a BR DVD becomes scratched I guess I will not be polishing it out to save the disc.

While you make some good points and I agree with most. I don't get this one. I'm getting HD VOD this year. It has already been released in some markets:

By 2009, it should be getting all the movies that come to BD. I just don't see how Joe and Jane Sixpack are going to think BD is worth it on ther 55" DLP RPTV viewed from 10' away. |
The comment was directed more toward general internet users,however the load that unicast viewers could put on any network,including Fios or optical networks will pull down bandwidth.I am looking forward to our community based Fiber optic network opening up to the public,but even here on 2 national backbones we still will be limited by local infrastructure capacity.widescale adoption of IPTV level service is not in most peoples near future,and even Fibre clients are going to be limited by local capacity and demand.
