Blu-Ray/HD DVD Cant we all get along!
Saturday, September 15th, 2007Warner Home Video has announced that it would postpone the release of its hybrid Total HD discs that combine Blu-ray and HD DVD layers to 2008. The company explains the delay with the decisions its management yet has to make and remains tight-lipped about technological side of the project.
Currently Warner releases movies in both next-generation formats, Blu-ray and HD DVD, but in this case the company’s retail partners have to carry two hi-def video disc for every movie from Warner, which effectively means that the company has two times less shelf space at retailers. In order to tackle the issue, engineers of Time Warner developed the so-called Total HD technology that allows to have both BD and HD DVD layers on a single optical disk. However, even though Total HD was promised to be rolled out in mid-2007, the company now postpones its release to Q1 2008.
“That is one less SKU to sell. With high-def, we’re trying to put Blu-ray and HD DVD on the same disc. Total HD is not coming until first-quarter 2008. We will find shelf space, said Warner Home Video’s vice president of sales and planning and operations Dan Miron at a session during the
“There is no expiration date on the viability of this concept, so we’re not in a rush to do it. We’ll do it when it makes sense and when it’s right,” said Steven Nickerson, Warner senior vice president of marketing management.
Both Blu-ray and HD DVD use 405nm wavelength laser to read data from the recordable media of the discs. However, the data layer of the Blu-ray discs is located 0.1mm from the disk’s surface, whereas the HD-DVD data layer resides 0.6mm deep from the disk’s surface. Warner’s engineers plan to create a disc with a Blu-ray top layer that works like a two-way mirror: it should reflect just enough blue light for a Blu-ray player to read, but it should also let enough light through for HD-DVD players to ignore the Blu-ray recording and find a second HD-DVD layer beneath, it was reported earlier. Theoretically, triple-layer DVDs can be created too, if DVD layer is located on the other side to the Blu-ray and HD DVD layers.
Even though the Total HD project sounds like a simplistic one, it involves pretty complex technologies on the optical disc side as well as custom-made replication equipment, which makes Total HD a pretty expensive initiative. Moreover, in addition to increased cost of the disc itself it involves increased cost of replication, which adds several dollars to already not really affordable Blu-ray or HD DVD, which cost $20 - $27 online. Moreover, Warner also has to standardize its Total HD with both Blu-ray disc association as well as DVD Forum. Given that LG Electronics has already released its hybrid player that sports both BD and HD DVD and Samsung Electronics is expected to follow, Warner Home Video may wait and see whether it actually makes sense to release dual-format discs.
