AES Updates Audio Guidelines for OTT Television, Video Streaming

Fri, 20 Oct 2017 17:24:49 -0400

The Audio Engineering Society’s Audio Guidelines for Over-the-Top Television and Video Streaming (AGOTTVS) technical group has released an update to its preliminary recommendations published in October 2016. To maintain and improve the sonic integrity and listening experience across multiple devices, the guidelines are focused on managing the loudness and loudness range of program and interstitial content distributed via OTT and by online video distributors (OVDs).
The AGOTTVS technical group was formed in early 2016 to study the many issues related to audio-loudness variations in distributed video content. The 50-member panel, a study group of the AES Technical Council Technical Committees TC-BOD (Broadcast and Online Delivery), announced publication of its preliminary loudness guidelines at the 2016 Los Angeles AES Convention (published as a Technical Document by the AES Technical Council). The recommendations addressed the fundamental issues of audio loudness in online television and video-content delivery from creation through distribution to the consumer experience.
With the release of the “Preliminary Loudness Guidelines” in 2016, the AGOTTVS group raised awareness of forthcoming, comprehensive, and ongoing work and invited all interested parties to join the effort. The group subsequently increased in membership and continued its work, drafting the enhanced OTT and OVD “Loudness Guidelines” documented in the current release.
Given the transitional nature of media consumption, the group intends to continue to update its recommendations. Future work will likely involve objective and subjective tests of DRC and loudness profiles to ascertain how metadata might be leveraged to more appropriately tailor content to devices and different listening scenarios.
The AGOTTVS group comprises volunteer members with expertise and/or interest in creation, distribution, and emission of professional audio. Membership is open to all stakeholders with a material interest in its work, regardless of AES membership status. Group participants include representatives of Amazon, Apple, BBC, CBS, Dolby, DTS, DTV Audio Group, Fox, Fraunhofer, Google, NBC Universal, Netflix, NHK, PBS, Starz, and Qualcomm.

Clear-Com has opened new and expanded premises in Montreal. The larger office space houses the Clear-Com Research team, dedicated to advancing the company’s global business with innovative, real-time communications and connectivity solutions.
Clear-Com Research was established in 2008, immediately following the acquisition of TalkDynamics. Since then, the research and development team has been instrumental to the company’s success with a number of significant award-winning innovations and will remain pivotal to Clear-Com’s future developments.
“This marks an exciting moment in the Clear-Com business,” says Mitzi Dominguez, CEO, Clear-Com. “Moving into a larger office space was necessary to provide a more collaborative and creative environment for our research and development team. The business is growing in all areas of our technology portfolio, and the Montreal office is key to our success.”

EchoStar 105/ SES-11 Successfully Launched on SpaceX’s Falcon 9

Wed, 18 Oct 2017 07:19:00 -0400

Last week, EchoStar 105/ SES-11 satellite was successfully launched into space on SpaceX’s Falcon 9 rocket from the Kennedy Space Center in Florida at 00:53 CEST. This is the second time SES has launched on a flight-proven Falcon 9 rocket, and the fourth launch with SpaceX. SES was the first commercial customer to launch on a Falcon 9 in 2013.
Built by Airbus, EchoStar 105/ SES-11 is a dual-mission satellite, providing SES with a C-band payload of 24 transponders of 36 MHz, owned and operated by SES, marketed under the name SES-11, and EchoStar with 24 Ku-band transponders of 36 MHz, marketed as EchoStar 105. The high-powered communications satellite replaces C-band capacity for AMC-18 and Ku-band capacity for AMC-15 at the 105 degrees West orbital slot.
“The successful launch of SES-11 further strengthens the centre of SES’s North American orbital arc and enables us to continue to provide a premium C-band service to the leading cable operators across the US,” says Martin Halliwell, Chief Technology Officer of SES. “We are also proud to launch on another SpaceX flight-proven Falcon 9 rocket and to continuously participate in innovative technology developments within the launch industry.”

Canon To Receive Technical & Engineering Emmy Award for 4K Zoom Lenses

Tue, 17 Oct 2017 17:17:52 -0400

Canon U.S.A. has announced that its parent company Canon Inc. will be recognized at the 69th Annual Technology & Engineering Emmy Awards for its complete lineup of 4K field production zoom lenses for large-format, single-sensor cameras, which includes all of Canon’s CN-E, CINE-SERVO and COMPACT-SERVO lines of zoom lenses.
Presented by the Academy of Television Arts & Sciences (ATAS), the Technology & Engineering Emmy Awards honor development and innovation in broadcast technology and recognize companies, organizations, and individuals for breakthroughs in technology that have a significant effect on television engineering.
“We are grateful to receive this esteemed recognition for our comprehensive collection of 4K zoom lenses for large-format single-sensor cameras,” says Yuichi Ishizuka, president and COO, Canon U.S.A. “As resolutions leap from HD to 4K and beyond, it is important to recognize the lens’ role in resolving those pristine images and the importance placed on manufacturers and optical engineers to keep pace and match the sensor technologies of the more advanced cameras and sensors in the market today. The images we admire on screen all start with the lens.”
The Technology & Engineering Emmy Awards will be presented on October 25, 2017, during the SMPTE 2017 Annual Conference in Hollywood, CA.

NAB NY 2017: Sony To Introduce Midrange Studio Camera

Mon, 16 Oct 2017 17:09:34 -0400

Sony is taking the wraps off a new camera at NAB New York this week. The HXC-F80 will likely be a player for live sports and event productions where native 4K or high-speed recording is not required.
“It’s a new midrange studio camera with features that are designed around the needs of sports broadcasters,” says Rob Willox, director of marketing, Sony Professional Solutions. “It’s for those who find the HDC-2500 or HDC-4300 is not a realistic option.”
The camera makes use of 2/3-in. CMOS sensors that have 15 f-stops of sensitivity and capture 1080p images at 59.94 or 23.98 fps. The camera has 3-Gbps and 12-Gbps output, and HD HDR capabilities will be added in mid 2018 (the camera will capture in BT.2020 color space). The first version of the camera will ship in January.
“The HDR capability uses HLG [hybrid log-gamma], and the HXCU-FB80 camera-control unit has a built-in 4K upconverter and can also control up to 24 cameras under the same control system,” says Willox. “This is the first camera in our lineup with that; cameras aimed for the lower end are usually point-to-point.”
Having the 4K upconverter in the CCU saves on circuitry in the camera and gives midrange productions an upgrade path that is sensible and simple.
In other Sony developments, users of the PXW-Z450 camera will have a firmware upgrade on Dec. 17. Version 3.0 will offer HDR support (both HLG and S-Log 3 with BT.2020 color space), simultaneous record of 4K HDR/HD SDR or 4K HDR/HD HDR, and 4K upgrades to cache recording and 4K S&Q up to 60p.
And the Venice full-frame digital motion-picture camera will make its U.S. debut (it was unveiled at IBC 2017) complete with film-look color reproduction, eight-step ND filter system, an anamorphic look, shallow depth of field, and more.

This handy info comes from our friends at Bittree Patchbays.
While using chemical cleansing agents or burnishing tools on the patch cord plugs or jack field itself is not recommended, periodic service to the patch cords and the exercising of the jacks should lead to many years of faithful service from your patch bays.
These instructions pertain to typical nickel-plated audio cords and video cords with nickel sleeves and gold-plated center contacts:
1. The patch cord ends should be cleaned with denatured alcohol (electronic grade 99.97%, not rubbing alcohol) and a soft, clean, lint-free cloth. When cleaning the gold-plated center pin on video patch cord plugs, use a small electronic grade foam swab only.
2. Using the cleaned patch cord, exercise the jacks by inserting and removing the plug as many as 10 times. The friction from this procedure helps to remove any built-up contaminants on the mating surfaces.
3. Repeat step #1.
Note: Slight scuffs in the patch cord plug’s outer plating are considered normal as the cords themselves are designed to wear-out long before the jack’s serviceable life is fully realized.
