Why is this man smiling? He thinks he has a shinny new stick to beat Sony with.
When Toshiba ceded the format war back in February, one thing they made clear was that they did not plan to make Blu-ray players and that they would pursue other technologies such as NAND flash memory and next generation CPUs to push HD adoption, and that they were determined to continue developing the DVD format. Many figured that the company either would focus on digital distribution of HD media or ultimately would join the Blu-ray Disc Association (BDA) to avoid falling behind in the presumed future of consumer electronics.

Little did anyone suspect such direct foreshadowing as Toshiba has now patented technology to get more capacity out of the existing DVD technology while retaining backwards compatibility.

Toshiba is again looking to move the HDTV bandwagon in its own direction and is pushing forward on several fronts to make good on its promise of leveraging its HD-DVD investment.

Based on details that are sketchy at present about exactly what Toshiba is up to with good old DVD, it seems that there is a two pronged approach, one based on better scaling techniques (presumably based around the Cell Processor video technology they were working on at CES this year) and the second based on disc storage limits.

According to Atsutoshi Nishida, President, and CEO of Toshiba Corporation, in an interview with the Japanese newspaper Daily Yomiuri, Toshiba plans to release DVD players based on Large Scale Integration (LSI) process technology later this year that is claimed to allow picture quality at nearly the level of HD-DVD on standard DVD. Then there is Toshiba’s newly patented DVD technology that looks to add two or more additional data layers per side and utilize parallel read heads to eliminate layer crosstalk that has limited previous attempts to squeeze higher storage density out of red laser DVD. One interesting possibility for such a change is the possibility of storing SD video on discs with tracking readable by any existing DVD player and using the additional layers to store supplemental information required to generate HD resolution video on a suitably equipped player.

What is not entirely clear is if the two developments are intended to be independent or combined. LSI appears to be an attempt to improve DVD up scaling and processing while the new patent seems to address space limitations that affect the practicality of putting HD content on DVDs that lead to new formats such as HD-DVD and BD in the first place. Combined they might address the space limitations of DVD completely.
