Sonic introduces DVD+R double layer recording

March 24, 2004

Besides Ahead and VSO-Software now also Sonic Solutions is offering DVD+R double layer writing in their software. Sonic's already has a lot of experience with double layer discs as the software was already capable of making double layer discs for the professional industry where double layers discs are pressed in factories. The company has introduced, like Ahead, some additional algorithms that make sure that the layer break is at the right place.

The double layer discs are written in such a way that you always write to both layers. This means that even if you are writing 100 Mb of data on a disc there will be 50 Mb of data on each layer. This has been done because of the logical addressing that is used on double layer discs.

HyperMux-DL's proprietary Double Layer features include:

Sonic SmartBalance: automatically balances data and video content across both disc layers for the fastest-possible write times. SmartBalance algorithms automatically adjust the layer break point to minimize lead-out time, dramatically speeding disc-burning time, while ensuring maximum read-back compatibility.
Sonic JumpSafe: selects the ideal title set layout and layer break point with precisely filled error-correction blocks to ensure optimum video playback and to avoid the frame stutter and visual distortion that commonly occurs in DVDs authored on standard formatting systems when the MPEG data streams are interrupted during layer switch.

Sonic's MyDVD, Sonic PrimeTime, DVDit! and RecordNow! consumer applications as well as Sonic's "Hollywood" professional applications, Scenarist and DVD Producer are the first to take advantage of this technology.
