 The new Sony MVS-7000X can be configured with one to six M/E channels. A variety of new 3-D cameras garnered attention at the recent NAB Show in Las Vegas, but there were an equal number of new products to support 3-D production and post. Here are a few highlights.
Sony said it had taken what it learned at the Masters, World Cup and other events over the past year and integrated that knowledge into its product development. As a result, the company showed new 3-D switchers, monitors, processors and conversion technology. The company introduced the Sony MVS-7000X switcher with enhanced 3-D functionality. The new switcher, available this summer, supports native 3Gb/s production and leverages many of the features from the higher-end MVS-8000X. It can be configured with one to six M/E channels, with split M/E capability, and, depending on the configuration, it can scale up to eight keyers per M/E with a 2.5D resizer for each keyer. Users can add up to four channels of internal effects, and the switcher can be configured with up to 80 inputs and 48 inputs in 8RU. Read the rest of this entry »

 Earlier this year, CableLabs, the nonprofit R&D consortium for cable TV operators, published a new specification for formatting, or “panelizing,” 3-D content into a frame-compatible format for use by cable TV systems in the United States. The spec, which is now being used across the industry, is designed to serve as a guide for producers, programmers and aggregators of stereoscopic 3-D programming so their programs are delivered properly and the end result is a pleasing viewing experience for the consumer. This specification, called Content Encoding Profiles 3.0 Specification (OC-SP-CEP3.0-I01-100827), can be found on the CableLabs website under “OpenCable specifications.” Read the rest of this entry »

 The PMW-TD300 3-D camcorder features a twin optical lens equipped with three half-inch CMOS Exmor sensors for each eye view. It was another year for new 3-D cameras at the NAB Show as major video manufacturers tackle the production issues and high costs that have been plaguing producers of 3-D content for TV and motion pictures. Counting those introduced last year, there are now literally dozens of options to choose from.
The industry as a whole is clamoring for operator-friendly, light and single-body production equipment that can replicate the 2-D HD production experience, and there was clear evidence this year that vendors understand the requirements and are working to make cost-effective production a reality. Here are a few notable cameras that were presented at this year’s show. Read the rest of this entry »

 The new technology will allow users to experience the immersive technology across all types of compatible 3-D displays with a single pair of active-shutter glasses. A group of consumer electronics manufacturing companies has joined to promote M-3DI as a single specification for 3-D glasses for home TVs, personal computers and motion picture theaters. Initial plans for the specification cover only IR sync, with the RF Bluetooth technology included on many current 3-D TV sets.
Both Panasonic and XPAND initially developed the new M-3DI standard. Other leading 3-D companies that have agreed to support the standard include Changhong Electric, FUNAI Electric, Hisense Electric, Hitachi Consumer Electronics, Mitsubishi Electric, Seiko Epson, SIM2 Multimedia and ViewSonic. Samsung, Sony and LG Electronics, three prominent 3-D manufacturers, are notably missing from the list of participants. Read the rest of this entry »

 Compared to desktop 3-D programs with dozens of menu options, Verto Studio 3D uses 15 buttons. A fully featured, 3-D modeling application has come to Apple’s iPad tablet computer that is said to be powerful enough for professionals but simple enough for beginning modelers: Verto Studio 3D.
Michael L. Farrell, a software developer, designed the new iPad-only program. The application uses OBJ format files and has controls for panning, moving, rotating, scaling and selecting objects, as well as material properties and other controls such as real-time Gouraud shading, dynamic lighting, vertex editing, multiple camera angles and an auto mode for manipulating every object in a scene simultaneously.

The 3D@Home Consortium and the American Optometric Association are hosting a special symposium on 3-D vision and health issues March 15 at the SUNY College of Optometry in New York City.
Panels will include “The Public Health Implications of Virtual 3-D,” “The Visual System and Virtual 3-D” and “3D: The User Experience Story.” Read the rest of this entry »

 The Consumer Reports test team said the passive 3-D glasses on the Vizio set dim the image less than any of the active-shutter glasses they had tried. Shown here is senior project leader Claudio Ciacci in the Consumer Reports lab. At last month’s CES, LG, Toshiba and Vizio announced passive 3-D TVs that allow the user to wear lightweight, inexpensive polarized glasses like the ones used in movie theaters. The polarized glasses are not only much cheaper, but replace the bulkier active-shutter glasses required by most current 3-D sets.
The first passive 3-D TV to hit the market was Vizio’s 65in VT3D650SV, a 1080p LCD TV that uses an edge LED backlight. Consumer Reports recently tested the Vizio model, pitting it against the Panasonic TC-P65VT25, a top-rated plasma 3-D TV.
In general, Consumer Reports said, there is a lot to like about the VT3D650SV. For one thing, the research team found the polarized glasses very comfortable to wear. The team also noted that consumers get four pairs of glasses with the TV, with additional pairs expected to cost from $10 to $30. That’s much cheaper than the $130 to $150 active glasses cost.

 The new 3-D specification specifies a delivery system that uses frame-compatible “plano-stereoscopic” signals to allow service providers to use their existing HDTV infrastructures to deliver 3-D TV services. The Digital Video Broadcasting (DVB) consortium has officially approved a new specification for the distribution of 3-D content, which will be used by broadcasters and other content providers as a way to transmit images using frame-compatible methods that are backward-compatible with existing DTV sets. Consumers need 3-D-compatible sets to view the new content, while those with HDTV sets will see a 2-D version of the same content.
The DVB’s Steering Board met Feb. 17 to vote on the new spec, which was unanimously approved. The specification will now be submitted to the European Telecommunications Standards Institute (ETSI) for formal standardization. BlueBook A154 “Frame Compatible Plano-Stereoscopic 3DTV” (DVB-3DTV) is available for download from the DVB website. Read the rest of this entry »

 Mounting two Meridian transmitters on the camera provides two high-quality HD signals that remain perfectly in sync all the away to the Boxx TV wireless receiver. As production crews continue to assemble the pieces to fill out the content creation chain for stereoscopic 3-D production that they have come to use in the 2-D world, one of the remaining parts is the wireless transmission of camera signals.
However, one of the biggest challenges when using traditional COFDM wireless camera transmission systems for two synchronized 1080p HD signals for 3-D is the availability of adequate bandwidth and ensuring reliable synchronization of images for the left and right eyes. That takes a bit of software algorithm development, which UK-based Boxx TV has said it has accomplished with excellent results.
The engineers at Boxx TV have developed the Boxx Meridian system in 2-D, which claims less than a 1ms delay and supports the use of bandwidth in the license-free 5GHz spectrum. They simply slap two Meridians together and they’ve got two high-quality HD signals that remain perfectly in sync all the way to the 3-D combiner. Read the rest of this entry »

 Over the recent holiday season, 3-D TV just didn’t sell — anywhere. Remember a year ago at CES 2010? The new “big thing” then was 3-D TV, and it was hyped everywhere. Manufacturers jumped onboard with 3-D hardware for the home, while programmers announced extensive plans for 3-D programming.
Now, with the CES 2011 conference behind us, it appears that the 3-D hype has dramatically subsided. The technology won’t disappear, but it will not get the same marketing emphasis as before. In American homes, at least, the industry now knows that 3-D TV will be a long, hard slog for years to come. Read the rest of this entry »
