Hybrid HD player from Samsung and Toshiba

παντως οπως λετε τα Mini -disk(ακομα ειναι τα αγαπημενα μου)

και τελειο ηχο εχουν και ειναι και πολυ μικρα!

αφου θυμαμαι το 2000 που τα ειχα σκασει χοντρα και ειχα παρει ενα φορητο

ολος ο κοσμος νομιζε οτι ηταν ρολοι και συγκριτικα με τα cd players ηταν και ειναι μικροσκοπικο!

αλλα βεβαια δεν κυκλοφορουσαν πολλα ετοιμα στα δισκοπολεια και επρεπε να κατσεις να τα φτιαξεις μονος σου!

(για εμενα αυτη ηταν η μαγεια τους!)

και για αυτο πιστευω ηταν ο κυριοτερος λογος που "πεθαναν"

επειδη ολοι βαριοντουσταν να κατσουν να τα φτιαξουν και ηθελαν απο τα ετοιμα τα cd.

μετα βεβαια ηρθε και το Mp3 player και τα σαρωσε ολα!

παντως εγω ακομα ακουω (αν οχι και τοσο συχνα)

mini disks αλλα και βυνιλια και πιστευω οτι οταν κατι ειναι καλο και ποιοτικο παρα το οτι δεν ειναι δημοφιλες kai trendy εμενα μου αρεσει!

Toshiba's Questionable Commitment to HD-DVD

Toshiba is selling the HD-A1 at unsustainable loss, and company President Nishida is calling for format unification.

HD-DVD clearly outshines Blu-ray

 

Based on the first round of reports, the HD-DVD format is garnering praise, but Blu-ray is garnering almost universal scorn from reviewers and enthusiasts alike. Reviewer Evan Powell, of projectorcentral.com, commented of Blu-ray: "The image quality does not measure up to what we would expect from a high-definition source, and it certainly falls short of the hype."

[BlizardBill]

Για να μην μπερδεύουμε και παραπληροφορούμε τον κόσμο που δεν ξέρει, να πούμε ότι τα 2 format έχουν ίδιες δυνατότητες κωδικοποίησης και άρα ίδιες δυνατότητες όσον αφορά την ποιότητα.

(μόνο διαφορά το μεγαλύτερο bandwith του BR, που μπορεί να προσφέρει καλύτερη ποιότητα με μικρότερη συμπίεση)

 

Αυτή τη στιγμή τα review μπορούν να κρίνουν μόνο την ποιότητα των 2-3 decoder που έχουν βγει, και το πόσο καλή δουλειά έχει γίνει στις ταινίες που έχουν βγει μέχρι σήμερα.

HD DVD to Use Thomson's New Film Grain Technology

 

From teamxbox.com:

Thomson announced that leading consumer electronics, software and technology companies are implementing its Film Grain Technology. Developed by Thomson's Technology division in collaboration with its Technicolor business, Film Grain Technology was recently adopted as a Society of Motion Picture and Television Engineers (SMPTE) registered disclosure document. Consumer electronics giants Toshiba and RCA; technology innovators Broadcom, Sigma Designs, Horizon Semiconductors and NVIDIA; and software leaders Microsoft and Sonic Solutions are set to deploy Film Grain Technology, with two Toshiba HD DVD players, an RCA HD DVD player and a Broadcom IC decoder now entering the marketplace.

 

The first tool of its kind formally documented in cooperation with SMPTE, DVD Forum selected Film Grain Technology for mandatory inclusion in HD DVD products. The technology allows compressed motion pictures to be delivered more efficiently and improves their visual quality. It enables film grain that is extracted before content is compressed to be faithfully re-created during playback.

 

Film Grain Technology is a streamlined, low-cost solution that is embedded in broadcast and home theater play-out devices. Broadcasters maximize bandwidth; packaged media content creators gain disk space; and viewers see movies that match the filmmaker's intent. It is easily deployed with H.264 compression (also known as MPEG-4 Part 10/Advanced Video Coding), and can be adapted to support other compression solutions.

Some insight on the dual layer 50GB discs.

 

This is really nothing new. We can make a few DL BD discs by going through hundreds of throw-aways. At least enough to get a few samples out for testing. But we've got no way of reliably making them in bulk. Until then, BD50 is a pipe dream at the mass consumer level. We have to manually (with much time consumed) test each disc because when yields are this low, statistical sampling fails to be useful.

 

But the way the discs are built are entirely different. HD-DVD uses techniques very similar to the production of a standard DVD, wheras Blu-Ray uses a newer method of production. As a result, the data layer on BRDs in very, VERY close to the surface. There is a nifty polymer that is supposed to curb scratching, but the manufacturing issues have to do with the fact that even on the single layer disc, there isn't a great deal of room for error. On the Dual layer disc, there is a small fraction of a millimeter between the data layer att he surface, and the discs are failing as a result.

 

At this moment, one out of every five BRD-25s off the line is a dud. The more complex media is impossible to mass produce without a better method at this moment (which sony is working very hard on, I assume).
