CES 2009

Those who want to equip their home theater with the best performance and service money can buy might want to take another look at SIM2. The company’s latest version of its HT5000E three-chip DLP projector combines reference-quality performance with unexpectedly personal service. The projector promises high-end image quality with the latest DLP chipsets from Texas Instruments. It includes three 0.95-inch DarkChip4 DMDs that work to display clear, uncompressed 1080p material.

Here's the skinny on that special set for special people.

LG showed a whole range of audio systems (upscale home theaters in a box) voiced by Mark Levinson. That's Mark Levinson the man (in LG's terminology, Mr. Mark Levinson), not the company which uses his name (he has not been associated with that company for many years).

Tom Norton broke the news about Dolby Pro Logic IIz, the first surround standard from the surround standard setter to incorporate height channels. It's an enhancement process, like Dolby Pro Logic II; not an encode/decode process, like Dolby Digital or TrueHD. It extracts what Dolby calls decorrelated non-surround elements, so it'll operate on things that belong in height channels, as opposed to, say, footsteps. It can operate in 7.1 or 9.1 configurations, without/with back-surround channels. Dolby's now in discussion with various manufacturers about licensed products. What I have to say about it is that it's a great idea -- I'd rather see folks adding height channels to their systems than useless back-surrounds (Dolby wants to make real sure I label that as my own opinion). And the implementation in speakers may be quite interesting, I imagine, everything from vertical structures (same footprint) to in-walls to speakers with top-mount drivers that bounce off the ceiling. Details here. Oh, and the pic is the Acer Aspire PC, glimpsed at the Dolby booth, and I mention it only because as I walked up to it, it said Luke, I am your father.

Shown here is the subwoofer that goes with the prototype LG audio system described above. The "tuba sub" name is my idea.

What struck me about my DTS briefing is that the formidable licensor of surround standards has dual strategies in two areas. One is sound enhancement for portable devices. For high-end surround headphone use, there's Head Tracker, which causes the soundfield to follow your head movements -- just like in this pic of a dude turning his head. Head Tracker will be built into an Onkyo receiver. For lower-end portable uses, DTS offers Envelo, which deals with the problems of highly compressed audio formats. DTS's other dual strategy arrives with the acquisition of Neural Surround, a matrixed adaptation format, which overlaps a little on existing Neo:6 territory. But the DTS people say the two circuits will find different applications, with Neo:6 (again) as the high-end player and Neural focusing on low-bit-rate applications like broadcast and MP3 (it's already used in XM, or now Sirius XM, satellite radio). DTS will be among the surround licensors to offer height channels with Advanced Neo. It will adapt 7.1 sources to 10.2, 11.2, or 12.2 channels, and is now being discussed with a/v receiver makers.
