CEA Defines ‘HDR’ as it Applies to UHD Sets

Fri, 28 Aug 2015 17:55:34 -0400

The Consumer Electronics Association (CEA) has announced the industry definition for high dynamic range (HDR) compatible video displays. HDR is a new capability that promises to deliver an expansive range of brightness and shadow detail, further enhancing the viewing experience. “HDR provides a significant step-up in delivering an incredible viewing experience for the consumer,” says Brian Markwalter, senior vice president, research and standards,CEA. “We encourage manufacturers and our industry partners to use this voluntary compatibility guideline to provide greater consistency and clarity while ensuring compatibility and interoperability across the full content development to display ecosystem.”

Paving the way for the introduction of HDR-Compatible Displays, the new CEA designation is designed to assist retailers and consumers in identifying display products that incorporate the interface and processing technology needed to display the new content properly. CEA and its display manufacturer members collaborated with leading content providers and distributors as well as other technology companies to establish the new display characteristics for HDR interoperability.

Many 4K Ultra High-Definition televisions (4K Ultra HD) will include early implementations of various next-gen technologies, including HDR, wider color gamut and higher frame rates, which provide a more realistic and immersive viewing experience.

CEA’s Video Division Board approved the following definition:

A TV, monitor or projector may be referred to as a HDR Compatible Display if it meets the following minimum attributes:

-Includes at least one interface that supports HDR signaling as defined in CEA-861-F, as extended by CEA-861.3.
-Receives and processes static HDR metadata compliant with CEA-861.3 for uncompressed video.
-Receives and processes HDR10 Media Profile* from IP, HDMI or other video delivery sources. Additionally, other media profiles may be supported.
-Applies an appropriate Electro-Optical Transfer Function (EOTF), before rendering the image.

“CEA’s leading role in defining HDR compatible displays complements the work of other organizations such as the UHD Alliance that are reportedly developing HDR-related performance parameters and guidance for the video content, distribution and hardware ecosystem,” Markwalter explains.

The new HDR interoperability guidelines build upon CEA’s extensive work in supporting and promoting 4K UHD technology. Previously, CEA collaborated with its member companies to develop characteristics and accompanying logos to designate 4K UHD TVs, monitors and projectors, as well as 4K UHD cameras and camcorders. CEA also has implemented a variety of promotional efforts to help educate consumers and retailers about the new display technology.

* Note: HDR10 Media Profile is defined as:

EOTF: SMPTE ST 2084
Color Sub-sampling: 4:2:0 (for compressed video sources)
Bit Depth: 10 bit
Color Primaries: ITU-R BT.2020
Metadata: SMPTE ST 2086, MaxFALL, MaxCLL

Panasonic’s AG-DVX200PJ Camcorder to Hit Streets in October

Thu, 27 Aug 2015 17:27:15 -0400

Panasonic’s AG-DVX200PJ 4K large-sensor, 4/3-inch handheld camcorder will begin deliveries in October 2015 with a suggested list price of $4,695. The DVX200PJ is the first in a new generation of large sensor, multi-format professional camcorders capable of capturing 4K/UHD, HD and SD, including cinematic DCI 4K 4096×2160. The company says it offers a suite of top-end features including 4K/24p* and 1080/60p recording, a V-Log L gamma curve and integrated 13X optical zoom lens design, the DVX200PJ will excel in documentary, reality television and event production, and prove an asset as a second-unit camera in 4K filmmaking.

The DVX200PJ is optimized for 4K/HD production, with strong bokeh effects and a V-Log L curve (measured at 12 stops) emulating the natural grey-scale rendition of the VariCam 35. The camcorder incorporates a newly developed 4/3” large-format MOS sensor with high sensitivity of F11, and offers variable frame rate recording from 2fps to 120fps in 1080p mode, enhancing the camcorder’s utility in sports and VFX production.

The handheld 4K camcorder offers an array of professional features including a newly-designed Leica Dicomar 4K F2.8~F4.5 zoom lens (4K/24p: 29.5 mm ~ 384.9 mm, HD: 28 mm ~ 365.3mm, 35 mm equivalent) with shallow depth-of-field, time-code in/out, 3G HD-SDI and HDMI 2.0 (4K) video outs (4:2:2 10-bit video), dual XLR audio inputs and 10 programmable user buttons.

The new Leica Dicomar 4K zoom lens with F2.8 aperture is an optimal choice for 4K video, with the ability to produce exceptional imagery and subtle bokeh. Leica’s exacting quality standards keep the occurrence of ghosting and flare to a minimum. Since the DVX200PJ is an integrated lens camcorder, there is no need to perform flange back adjustments or shading corrections when changing lenses. Even with a large diameter lens, the camcorder’s weight and balance have been optimized to facilitate agile, mobile 4K acquisition. With superb center-of-gravity balance, the camcorder is ideal for flexible shooting applications such as mounting on today’s popular stabilized camera rigs.

Three manual operation lens rings, 13x zoom (Cam driven), focus and iris, provide a comfortable manual control similar to an interchangeable lens camera, but without the need for actual lens changes. The zoom ring’s solid feel and smooth action allow delicate ultra-slow zooming. In addition, the camcorder’s multi-step zoom control provides fast response and smooth zoom action, yielding the creative freedom every camera operator desires. The zoom control on the handle enables variable speed zoom, allowing fine zoom control even for low angle shots.

The DVX200PJ works “out of the box” with integrated lens, viewfinder and included battery.

Consumer Sentiment toward Overall Economy Drops Amidst Stock Market Volatility, According to CEA Indexes

Wed, 26 Aug 2015 16:57:42 -0400

Consumer confidence toward the overall economy and technology spending dropped in August, according to the latest data released today by the Consumer Electronics Association (CEA)®.

Overall Economy

The CEA Index of Consumer Expectations (ICE), which measures consumer sentiment about the U.S. economy as a whole, dropped 3.7 points from July to reach 170.1 in August. August’s ICE also tracks lower for August year-over-year.

“August’s drop in sentiment toward the overall economy comes in the midst of a significant stock market correction,” said Shawn DuBravac, Ph.D., chief economist, CEA, and author of the New York Times best-seller Digital Destiny: How the New Age of Data Will Transform the Way We Work, Live, and Communicate. “Despite gathering storm clouds, some indicators suggest signs of strength and resiliency. Looking ahead, consumer spending is pointing to healthy growth in the coming quarters.”
Technology Spending
The CEA Index of Consumer Technology Expectations (ICTE), which measures consumer expectations about technology spending, dropped 1.7 points to 86.7 in August.

“Viable concerns are now present heading into the back half of the year on the trail of slowed economic growth,” said DuBravac. “Yet, historical precedence suggests that consumer tech spending shows resiliency in times of economic decay, as consumers opt to stay home and focus their consumption on tech-related categories. 2015 could materialize in a similar way.”

Making Recycling Electronics as Easy as Purchasing Them

Mon, 24 Aug 2015 10:58:45 -0400

LCD TVRecycling electronics is a national issue, and it requires a national approach. The CE industry’s eCycling Leadership Initiative
aims to increase collaboration from all levels of the industry and government to get more consumer electronics recycled. The initiative has increased the amount of electronics recycled nationally each year since its inception—from 300 million pounds of recyclable electronics in 2010 to more than 660 million pounds last year, a 120 percent increase.

Two key elements to achieving this success are increasing the number of collection sites available to consumers and raising consumer awareness to their availability. In addition to sponsoring recycling locations and websites that help consumers easily locate places to recycle their electronics devices, the industry has also produced public service announcements for radio and television on the importance of recycling old electronics. To date, those announcements have reached an audience of well over 100 million people. To reach a younger audience and their parents, the CE industry worked with Young Minds Inspired to create a school curriculum for fourth through sixth graders explaining what ecycling means to them and their communities.

According to the latest research, the average U.S. household owns roughly 21 CE products and three out of five homes (59 percent) know where they can recycle their old devices. In large part due to the CE industry’s efforts, there are more than 8,500 responsible recycling locations available to consumers throughout the country. And by the end of 2014, nearly all (99.9 percent) of the recycling completed by the eCycling Leadership Initiative’s participants was conducted in third-party certified recycling facilities.

Walter Alcorn, vice president of environment affairs and industry sustainability, CEA, says, “Our electronics devices are becoming lighter than ever. So even as we see continued increases in the total weight of CE recycled—about six percent more than last year’s total—we are continuing to recycle an even greater percentage of CE than in years past.”

Audio-Technica Talks Microphones in the Immersive Age

Fri, 21 Aug 2015 17:48:17 -0400

Audio TechnicaThe imminence of the object-based–audio era has not escaped notice at Audio-Technica. Neither, for that matter, has the fact that sports-media content is changing radically, with more of it moving to streaming and, in the process, often to earbuds as the final audio-monitoring method for consumers. What’s not changing is the fact that these new multi-object soundscapes will continue to be built largely using mono and stereo microphones.

“Playback formats are definitely changing,” says Michael Edwards, VP, product and market development, A-T, “but the role of the microphone is still to capture the moment.”

A-T has periodically considered entering the market for multichannel dedicated surround-sound microphone but has continued to favor its broadcast stalwarts: shotgun mics like the BP4073 and BP4071 mono and the BP4027 and BP4029 stereo.

“What we’ve seen is that most of the surround beds are still built using either closely or widely spaced microphones, depending on the engineers’ tastes,” says Edwards. “Stereo microphones have become the primary tool for building surround sound, with mono microphones used for specific effects to fill in. As we move into the next generation of broadcast audio for sports, the creation of the surround bed will become ever more complex.”

As important, adds Chris Nighman, product manager, wired products, whether an A1 or A2 prefers to create a stereo image using either an X-Y or a mid-side element configuration, mono compatibility will remain a critical necessity well into the object-based future. “That’s something that broadcast can never lose sight of, even on mobile platforms,” he stresses.

Both executives emphasize that, while consumer playback configurations ranging between 11 and 22 channels (or objects — the terminology remains in flux) will offer listeners new ways to access sports on television while presenting field technicians with new and interesting challenges, most viewers won’t feel compelled to access these new formats. Whatever format they do listen through, however, they will have had their expectations for sound quality set high, simply because broadcast sound has been so good for so long.

“And that’s always going to start with the sound source: the microphone,” says Edwards.

In fact, he adds, how audio is captured at the elemental level could influence the overall experience for consumers. For instance, the audio for an announcer located on a sideline or near the field of play may not be completely free of ambient sound, which would affect whether a consumer turns off the announcer object. Or the ambient audio around a second announcer speaking another language could be a mismatch with the rest of an event’s background sound. “The way audio is captured in the first place can significantly influence how it’s [experienced] later,” he points out.

In fact, says Nighman, the trend toward personalization of the broadcast-audio mix puts an even greater premium on sound quality at the point of capture, because the final mix may no longer be completely under the control of an experienced A1.

Edwards says this could contribute to the use of more microphones per show and more types, such as the boundary microphones that he sees increasingly used for golf and other sports where microphones need to be present but inconspicuous. (He and his team are aware of the type of “remote-integration” methodology pioneered by ESPN and how it could affect the number of kinds of microphones deployed.)

And, although microphones and speakers will remain the analog end points of what has become an almost all-digital enterprise, even microphones will ultimately find their way into networked audio. In 2014, A-T introduced its ATND971 cardioid condenser boundary network microphone, which is compatible with the Dante network.

“The ability to manipulate the microphone remotely, which is something that networking enables, will become more important in the future,” Edwards asserts. “Things are changing, but the microphone remains the basic building block for broadcast sound.”

Understanding 4K & Necessary Data Rates from Belden

4K has made some hefty promises to provide better detail, texture, clarity and resolution by quadrupling the number of pixels being delivered. Also known as ultra-high definition resolution, 4K presents four times the picture resolution that standard high-definition resolution offers.

Although displays and technology already exist to support 4K, the lack of 4K content and programming prevents it from permeating the market (although 4K displays can improve the look of standard high-definition content – not just ultra HD content). Most 4K displays and panels are larger in size (at least 55 inches) because the benefits of ultra-high def resolution are less visible on smaller displays.

As it becomes more widespread, 4K will be beneficial across digital cinema, TV, gaming, the internet, and commercial applications (video projection, digital signage, etc.).

Translating to a resolution of approximately eight million active pixels (4096 pixels wide by 2160 vertical high), 4K is delivered in an uncompressed format.

This uncompressed format requires more bandwidth than traditional high-definition. Table 1 below illustrates the data rates that are required to support 4K resolution for different color options at 60 frames per second. At 30 frames per second, the bandwidth requirements are halved.

Suitable infrastructure is also necessary to deliver 4K resolution, including systems that are designed and engineered to handle new frame rate considerations, mismatched resolutions, and source/display compatibility.

Another factor to consider with 4K is its required data rate. To support ultra-high definition resolution and maintain color information, higher data rates are needed as shown in Table 1. The HDBaseT connectivity standard has yet to catch up; it supports HDMI 1.4, not HDMI 2.0. HDBaseT is able to support 4K under certain conditions, but some features will be missing. HDMI 1.4 currently operates at a 10.2 Gbit/s data rate; HDMI 2.0 operates at up to 18 Gbit/s data rate for the highest 4K resolution and color depth. It is possible that a new-generation HDBaseT chipset will be required to support HDMI 2.0 capabilities. For now, many manufacturers are introducing HDBaseT products that can support 4K video within HDMI 1.4.

Due to bandwidth requirements, the industry hasn’t agreed on which cabling options are best suited to deliver 4K signals over longer distances. Signal integrity may be a major issue for proper 4K connectivity; noise interference and increased distances can impact signal quality.

The HDBaseT Alliance indicates that shielded Category 5e and Category 6 cabling will support 4K video, but other vendors state that better cabling is needed (for example, Category 7A). To find the true answers, further research and study are essential.

Belden hopes to verify these claims by doing additional testing in our own labs using different HDBaseT equipment offering 4K capability, along with different cable designs, including shielded Category 6, shielded and unshielded Category 6A, and Category 7A cables. As this testing is completed, we will keep you updated on the findings.
