There are several exhibitors showcasing “vibro-tactile” audio experiences, including vibrating earbuds and headphones. But one of the more interesting is VibeAttire, a vest wired with vibrating motors and a small processor that converts audio signals into vibrations and maps them through the vest. It sounds weird, but it was actually a very cool immersive experience. We listened to MP3s and watched part of “The Matrix” while wearing the vest, and can imagine a 3D movie or game with it on could be awesome.

JVC was showing off its 4K DLA-RS4000 projector utilizing D-ILA technology, which reps claim delivers a native contrast ratio of 70,000:1 using a 3500 ANSI lumen xenon bulb. The projector looked great with amazing color and depth from both 1080 and 4K source material. They even showed a stacked pair of projectors running full 4K left-eye right-eye polarized content on a silver screen. Despite some ghosting issues with some of the content, it was clear to see how full 4K 3D projection could create an exceptionally immersive 3D experience.

Dyyno, a venture-backed start-up, was showing a live-streaming P2P application that allows anyone with a webcam to start streaming live to 1 or 100,000 people simultaneously at zero marginal cost. Dyyno also has a plug-in for WebEx that allows you to stream your video directly to your meeting guests. And live streams can be saved for access later as VOD.

We’re just in the “first inning” of a new game of digital content delivery, said panelists on the ETC’s Thursday afternoon session on connected devices. And 2010 will be a year of experimentation, surprises, and gathering data. “Over-the-top services” deliver entertainment over the Internet and create opportunities for content creators to engage with their audiences in new ways. This panel of studio and CE executives discussed the emerging services and technologies that will enable consumers to discover and view content in the future. Highlights included discussions of personalization, scalability, multi-screen activity, the connected home, and a need for standards.

Fujifilm is demonstrating to attendees just how ubiquitous 3D may soon become. The company is showcasing two interesting products: a 3D consumer digital camera, the 10 megapixel 2D and 3D FinePix W1 Real3D camera ($599), and the FinePix V1 Real3D autostereo viewer.

Sarnoff (Norm Hurst) was showing its Visualizer Digital Video Test Pattern, designed to clearly delineate flaws and artifacts in origination, compression, and display, including audio-video sync. That then led us to continue an old discussion about the need for 3D Test Patterns — something we’d like to hear about if you’re interested in them.

If you thought HDMI made connections simpler, wait until you see HDBaseT… The demo we saw was of a single Cat-5 ethernet cable carrying power, uncompressed 1080p video, ethernet, and control data (e.g. the ability to get access to USB devices across the network). One connection –- for POWER, the WEB, and HD Video and sound…

The expansion of online video content requires better metadata to ensure that consumers can find the programs they’re seeking. KC Blake provided an overview of the ETC’s efforts, in conjunction with major Hollywood studios, to streamline the creation and transmission of this data to current and future digital service providers and CE devices. ETC has set up an industry reflector forum for the exchange of ideas and moderated discussions on specific topics around the standardization of distribution metadata.

Tablets powered by Tegra, as well as stereoscopic 3D, were the focus of NVidia’s Thursday press conference at the Hilton’s Shimmer Cabaret. NVidia unveiled its next-generation Tegra, a new chip with 8 independent processors and Dual Core Cortex-A9 CPU. President/CEO Jen Hsun Huang discussed how NVidia technology can be used to bring 3D to PC entertainment, including desktop PCs using new 3D Vision-Ready, 1080p, 120Hz LCD panels from display companies, including Acer and Alienware.

LG Electronics began CES with a standing room-only press conference and news that LG’s 2010 HDTVs with NetCast Entertainment Access will feature embedded Skype software. Skype will be available on 26 new LED, LCD and plasma HDTVs planned for 2010. By purchasing a separate camera with an integrated microphone, consumers can conduct HD video and voice calls by accessing Skype through the NetCast on-screen menu. LG also introduced a family of Network Blu-ray Disc Players including the BD590, a Blu-ray player with integrated hard drive, designed to create a Media Library.
