Panasonic, Expand3D Propose a Standard for Active 3D Glasses

The initiative is designed to promote acceptance of 3D-ready TVs and computers.

 

[by Carolyn Giardina, The Hollywood Reporter]

Panasonic and Xpand 3D has introduced new technology that the companies hope could bring compatibility between the 3D glasses used for different brands of 3DTVs, computers, home projectors and cinema projection.

Currently, all 3D glasses are not the same. And that can be a hassle for consumers.

With this in mind, Panasonic and Xpand have introduced M-3DI technology, which they believe has the potential to become a future standard for 3D active shutter eyewear. They also believe this initiative could help to accelerate penetration of 3D ready devices.

There has been plenty of discussion in professional circles about the notion of universal eyewear to simplify 3D for the consumers. However there are a lot of moving parts involved in creating a standard. There is also always the potential for a format war if stakeholders are not in agreement.

The Consumer Electronics Association has formed a 3D technologies working group and is currently accepting proposals for an active 3D eyewear standard. The deadline to submit a proposal is March 31. “We already have one that has been submitted,” Brian Markwalter,senior vp, research and standards, told The Hollywood Reporter.

Soon there will be at least two.

“We are going to submit (M-3DI) as a proposal,” David Chechelashvili, head of Xpand’s enterprise division, told THR. “We are hoping CEA accepts our proposal because so many companies are behind it.”

Panasonic and Xpand reported that companies that have agreed to participate in supporting M-3DI include Changhong, Funai, Hisense, Hitachi, Mitsubishi, Seiko Epson, SIM2 Multimedia and ViewSonic.

Acknowledging that additional 3DTV set makers such as Samsung and Sony are not on this list, Chechelashvili related that they are in discussions with additional manufacturers and “hope they will join.”

Xpand actually already offers its own brand of universal active glasses. “This product replaced a standard since there was no standard in the market,” Chechelashvili explained. “But standards are necessary in the market, and a standard will kill our universal product.”

There are essentially two main types of 3D glasses. Active means that the switching between the left and right eye image is accomplished in the glasses, which require power. Passive glasses don’t require batteries; they essentially create 3D by restricting the light that reaches each eye.

“(Active and passive glasses) have different strengths and weaknesses,” CEA’s Markwalter said. “There have been discussions about standards for passive, but when we started creating the request for proposals, active was the technology that most needed standardization.

“Passive (standards) may be needed as well,” he added. “Passive is coming into the (consumer electronics) market pretty quickly.”

RealD, for instance, makes active glasses for partner set manufacturers, but is interested in passive systems for the home. Its theatrical system is also passive.

In January, RealD and Samsung Electronics LCD Business said are jointly developing a 3D display technology called RDZ that would be compatible with the same 3D eyewear used in RealD 3D theaters.

Panasonic and Xpand reported that plans are to license the M-3DI technology beginning next month. This technology would essentially provide a communication protocol between 3D active-shutter eyewear and 3DTVs, front projectors, computers and cinema systems (essentially Xpand’s active system). The M-3DI participants also aim to organize quality control testing and approval procedures.

Specification for Naming VFX Image Sequences Released

ETC’s VFX Working Group has published a specification for best practices naming image sequences such as plates and comps. File naming is an essential tool for organizing the multitude of frames that are inputs and outputs from the VFX process. Prior to the publication of this specification, each organization had its own naming scheme, requiring custom processes for each partner, which often resulted in confusion and miscommunication.

The new ETC@USC specification focuses primarily on sequences of individual images. The initial use case was VFX plates, typically delivered as OpenEXR or DPX files. However, the team soon realized that the same naming conventions can apply to virtually any image sequence. Consequently, the specification was written to handle a wide array of assets and use cases.

To ensure all requirements are represented, the working group included over 2 dozen participants representing studios, VFX houses, tool creators, creatives and others.  The ETC@USC also worked closely with MovieLabs to ensure that the specification could be integrated as part of their 2030 Vision.

A key design criteria for this specification is compatibility with existing practices.  Chair of the VFX working group, Horst Sarubin of Universal Pictures, said: “Our studio is committed to being at the forefront of designing best industry practices to modernize and simplify workflows, and we believe this white paper succeeded in building a new foundation for tools to transfer files in the most efficient manner.”

This specification is compatible with other initiatives such as the Visual Effects Society (VES) Transfer Specifications. “We wanted to make it as seamless as possible for everyone to adopt this specification,” said working group co-chair and ETC@USC’s Erik Weaver. “To ensure all perspectives were represented we created a team of industry experts familiar with the handling of these materials and collaborated with a number of industry groups.”

“Collaboration between MovieLabs and important industry groups like the ETC is critical to implementing the 2030 Vision,” said Craig Seidel, SVP of MovieLabs. “This specification is a key step in defining the foundations for better software-defined workflows. We look forward to continued partnership with the ETC on implementing other critical elements of the 2030 Vision.”

The specification is available online for anyone to use.
