Hybrid players due early next year

With no foreseeable happy ending to the HD-DVD/Blu-ray format war, NEC has done us all a favor today by shipping a chip that is compatible with both formats.

According to Reuters, "the chips go on sale for 10,000 yen ($84), roughly the same price as NEC Electronics' chips which read only Blu-ray or only HD DVD formats." Players incorporating the new chip will be available sometime early 2007, reports AkibaNews.

While we now have silicon to rule both formats, the optical pick-up lens capable of reading both HD-DVD and Blu-ray is still currently in development. Until such a hybrid pick-up becomes reality, dual-players must utilize two separate lenses, which no doubt drives up costs.

A NEC spokesperson commented that a hybrid chip and optical pick-up would likely make up more than half of the cost of a player.

Developments to bridge the gap between the two warring formats isn't exclusive to hardware. Warner recently filed a patent outlining plans of a hybrid-disc that will be compatible with both HD-DVD and Blu-ray by means of layering one format on top of the other.

Just a note: PCM is lossless as it isn't compressed at all.

And for comparison with the earlier post (and really as a reply to it) about blu-ray, here is the info about HD-DVD from wikipedia (emphasis is mine):
"HD DVD can be mastered with up to 7.1 channel surround sound using the linear (uncompressed) PCM, Dolby Digital and DTS formats also used on DVDs. In addition, it also supports Dolby Digital Plus and the lossless formats Dolby TrueHD and DTS HD. Currently, most DVD movies are made with 5.1 channels of surround sound. There are relatively few titles that offer 6.1 channels of surround sound. On HD DVD the Dolby formats are mandatory, meaning that a Dolby Digital or Dolby Digital Plus track may be used as the sole soundtrack on a disc , because every player will have a decoder that can process any of these bitstreams.[6] For lossless audio in movies in the PCM, Dolby TrueHD or DTS-HD formats, HD DVD discs support encoding in up to 24-bit/192 kHz for two channels, or up to eight channels of up to 24-bit/96 kHz encoding.[7] For reference, even new big-budget Hollywood films are mastered in only 24-bit/48 kHz, with 16-bit/48 kHz being common for ordinary films."

This in my eyes looks like they are quite equal in the audio department because they both have the option of only including the "good old" Dolby Digital (AC3), which is lossy as hell.
