Single-Source Stereo and Microstereoscopic 3D
3DTV presents challenges: two lenses and cameras per shooting position, convergence operators and stereographers, graphics issues, ghost images, and false size perception or discomfort for viewers. Until 3DTV becomes the norm, events might be shot in both 2D and 3D versions. Addressing the discomfort issue, researchers have come up with something called "microstereopsis," which, coincidentally, reduces or eliminates the other challenges noted above. Unfortunately, it also reduces the 3D depth sensation.
A similar situation once existed regarding stereo sound. Early TV-radio stereo simulcasts often used two different mixes for stereo and mono, and so-called "ping-pong" stereo once offered listeners a strong indication of the difference between stereo and mono.Today, however, stereo sound is usually captured with "single-source" techniques that are mono-stereo compatible. Beginning in 1881, stereo sound was compared to stereoscopic imagery. Might the single-source-stereo-like techniques of microstereopsis, therefore, be applicable to 3DTV?
Please join our guest speaker, Mark Schubin, as he explores the possibilities.

Guest Speaker: Thomas M. Coughlin, Coughlin Associates
The implications of ever higher resolution content processed in today's digital media workflow from content capture, ingest, editing and post production, content delivery as well as archive and preservation are of concern to many in the Motion Imaging Industry. There is also a growing trend toward the use of network storage rather than direct attached storage for many performance-oriented M&E applications as the capabilities of storage networks has improved and costs have dropped.
The development of the digital storage hierarchy to support these activities has led to the use of many types of storage devices including capacity hard disk drives, performance hard disk drives, optical discs and magnetic tape. In addition to these traditional storage media and systems flash memory has emerged as a strong storage contender, particularly in rugged content capture devices as well as in high performance content delivery systems.
In this SMPTE PDA session, our guest speaker Coughlin Associates' Tom Coughlin will provide an overview of these technologies and where they may best apply. In addition, some results from a recently completed survey of M&E professionals conducted by Coughlin Associates will be presented to show current status and developing trends in this highly demanding and storage intensive industry.

Improving News Workflow Efficiency
Guest Speaker: Bob Bolson, Harris
When news breaks, workflow efficiency can mean the difference between getting to air first - or not getting there at all. Building your newsroom around a shared storage architecture with integrated editors helps deliver the quickest time from content acquisition to air. Larger newsrooms can reap additional rewards by implementing a low-resolution workflow that allows scores of users to work on content simultaneously.
In this informative session, Bob Bolson from Harris, talks about today's tools for optimizing your news production, from ingest through NRCS integration of your editors to playout.

Producing Stereoscopic Content: What Makes Great 3D Great and What Can Go Wrong?
Guest Speakers: Peter Wilson, Principle, High Definition & Digital Cinema, Ltd., and Matt Cowan, Chief Scientific Officer, Real D
It has been said that not all stereoscopic 3D content is created equally. There are a number of technical and perceptual factors that must be considered when producing and projecting stereoscopic content. If these factors are addressed effectively, the excitement of the 3D experience is maximized. Don't pay sufficient attention to them and the excitement is diminished, at the very least, or even worse, the experience can be just plain uncomfortable for the viewer.
Please join our special guest speakers Peter Wilson and Matt Cowan as they discuss differences between good and bad 3D content and how image acquisition and projection can impact 3D image quality.Stereoscopic Cinematography

DTV Transition: Terrestrial DTV Signal Reception - An Update From the Field
Guest Speaker: Pete Putman, ROAM Consulting LLC
The transition to digital terrestrial TV broadcasting is closing in on D-Day - When analog (NTSC) broadcasts from full-power TV stations will shut down for good.
Vestigial sideband modulation (VSB), the standard used for terrestrial digital TV transmission in the United States, has come a long way since the first problematic tests in 1997 and 1998. Today's VSB receivers have evolved to fifth- and sixth-generation designs that can provide steady reception of DTV signals in numerous locations where analog TV reception would be all but impossible.
Pete Putman of ROAM Consulting, shares field test results that demonstrate just how well these receivers work for indoor and outdoor reception of 8VSB signals with simple antennas, through mountains, over long distances, and even underground, using the latest standalone set-top boxes and NTIA converter boxes.

DTV Transition: Working Through the Early Challenges of a Post Analog World
Guest Speaker: Bill Hayes, Iowa Public Television
When the DTV switch is actually flipped, there are two things on which we can count. First, we can expect that the transition will not be 100% problem free. The second thing is the fact that all parties involved in the switch will need to quickly adopt a highly cooperative approach to avoid finger pointing when things don't work as planned.
Please Join SMPTE PDA Now's Bill Hayes, Iowa Public Television (IPTV), as he discusses the challenges that will likely surface immediately after the switch, what work is currently being done to address them, and how we can best work together for a successful DTV transition.
