Shure Counters Attempts To Curtail RF Carve-Outs

Fri, 17 Apr 2015 14:46:43 -0400

The run-up to the Incentive Auction of Television Broadcast Spectrum continues to spur Machiavellian intrigue and tactical skirmishes worthy of an entire season’s worth of Game of Thrones. The auction, scheduled for mid 2016, is expected to see much of the 600 MHz spectrum now used by wireless microphones critical to broadcast sports and ENG auctioned off. However, the FCC had earlier this year approved a 600 MHz “band plan” that allocated 11-MHz-wide guard bands, including a uniform duplex gap (a special guard band used to separate uplink and downlink spectrum), to prevent harmful interference between licensed services.

However, CITA, the trade association representing wireless-service providers, such as Verizon and AT&T, last week filed a technical report asserting that those licensed wireless microphones would cause interference with mobile handsets within 5 MHz of those guard bands.

According to Mark Brunner, director, PR, Shure, the company filed its own ex parte technical report countering CITA’s assertions on Monday April 13.

“We believe the [FCC’s] original band plan did a proper analysis and provided for a proper plan under which all the services specified could co-exist,” says Brunner. “The [CITA] study was flawed on several of its parameters, and we pointed those out in our technical report, along with additional analysis from our own research.”

The importance of RF spectrum in the UHF band, where the 600 MHz range resides, is underscored by the intensity of the lobbying around what is barely a tenth of the spectrum going to auction next year. Earlier this year, the AWS-3 paired-spectrum auction conducted by the FCC drew $44.9 billion for the 65 MHz of that frequency range, nearly three times the initial estimates of what that spectrum would fetch.

Says Brunner, “We have to counter any threats to the commission’s original band plan with accurate, real-world data on how wireless microphones work, in terms of things like power consumption, and their importance to broadcasters.”

Yamaha Debuts Rio 64-Input/Output Rack

Thu, 16 Apr 2015 09:26:38 -0400

Yamaha Commercial Audio has announced the NAB 2015 launch the new RSio64-D I/O audio interface providing up to 64 inputs and 64 outputs with Dante/Mini-YGDAI card conversion for broadcast, recording, live sound, and other professional audio applications at booth #C1450. The new RSio64-D is a digital ‘Bento Box’ of sorts, the Japanese equivalent of a lunch box with compartments that contain various parts of the meal.

The Yamaha RSio64-D is a Dante/Mini-YGDAI format converting audio interface that can handle up to 64 inputs and 64 outputs while providing router functionality. It allows a wide range of input/output formats to be connected to a Dante network via four card slots that accept the comprehensive range of Mini-YGDAI cards available, making it an ideal choice for a wide range of applications. The RSio64-D can also be remotely controlled from Yamaha CL and QL Series digital consoles.

“The Rsio64-D is a card slot device that has slots for the customer to choose what “flavor” of format they require, states Marc Lopez, Marketing Manager, Yamaha Commercial Audio. “We expect that our customers will utilize the ‘Bento Box’ to the max as it will provide significantly enhanced flexibility for sound systems that include the Dante audio network.”

To make the RSio64-D even more convenient and easy to use as a format converter and router, presets for seven basic routing patterns are built in including routing between Mini-YGDAI cards. A rotary switch on the front panel allows direct selection of one-to-one Dante/Mini-YGDAI routing, branched Mini-YGDAI/Mini-YGDAI routing, and other options designed to suit a variety of applications.

Used with the R Remote software application or a CL or QL Series digital console, full matrix patching will be supported so that more complex routing can be set up as required.

Since its introduction in 1998 the Mini-YGDAI format has evolved to encompass a broad range of host devices and cards. The RSio64-D is an innovative solution that not only makes it possible to utilize the Dante network, but also enables convenient routing between Mini-YGDAI cards. The RSio64-D will greatly expand the utility and power of sound systems built around Dante capable products.

The Yamaha RSio64-D has a target MSRP of $3,000. Shipping is scheduled to begin this summer.

Blackmagic Design Updates URSA Cameras

Wed, 15 Apr 2015 09:22:43 -0400

Blackmagic Design’s Blackmagic Camera 2.3, a major update for Blackmagic URSA cameras, adds support for HD window mode allowing 150fps recording in 1920 x 1080 resolutions, adds support for ProRes 444 XQ, allows recording onto 2 CFast 2 cards simultaneously in RAW allowing higher frame rates in RAW and also adds support for the new V2 4K URSA image sensor which allows Ultra HD capture to 120 fps.

This new software update is available now to download from the Blackmagic Design support web site.

Since its introduction, Blackmagic URSA has been used on multiple television commercials and feature films worldwide. These high-end customers have provided some great feedback on features most needed and this free software update incorporates many of the requests.

The new “window mode” allows customers to select up to 150 fps for allowing slow motion effects and other creative cinematography. The window mode keeps data rates lower, even when running at high frame rates because it does not use the whole 4K image sensor, but takes a 1920 x 1080 resolution window from the center of the sensor. This allows the camera to capture to higher frame rates than possible when using the whole sensor.

The new ProRes 444 XQ codec allows Blackmagic URSA cameras to record into the highest quality ProRes format and this allows incredible compatibility with both DaVinci Resolve and also Final Cut Pro X. ProRes 444 XQ is ideal when you need extremely high quality, but also need compatibility with a wide range of software that might not handle RAW files.

This software update also allows recording RAW to two CFast 2 cards simultaneously. This allows every second RAW frame to be sent to alternate CFast 2 cards so the recording data rate is doubled in comparison to using a single card. Because CFast 2 cards are extremely fast, being able to use two of them at the same time when recording allows extremely high data rates, which is vital when recording RAW. Because the frame rate is not fixed in RAW files, this means shooting RAW is ideal for high frame rate shooting and is more flexible when customers need to change the speed of the clips during post production.

This new Camera Update 2.3 also adds support for a new version of the URSA image sensor that allows higher frame rates. This new 4K v2 sensor is now rolling out in new URSA cameras and allows high frame rates full resolution 4K of up to 120 fps. This means customers can now go beyond 80 fps and up to 120 fps when running high resolution. Because Blackmagic URSA is user upgradable, this new sensor will also be offered as an upgrade so customers can increase the frame rate of their URSA cameras if required. Details on availability and cost of this 4K v2 sensor update will be available late in April.

“We are extremely happy to make this software update available free of charge for URSA customers,” says Grant Petty, CEO, Blackmagic Design. “Blackmagic URSA customers have been giving us some great feedback on features they would like to see added to the camera and because URSA has so much power, we have been able to say yes! We have added these new features and there is more to come so we cannot wait to see what our customers do with this new update when they get the chance to use it in production!”

Key features include support for windowed recording up to 150 fps in 1920 x 1080 HD resolution; ProRes 444 XQ codec for recording and playback; support for recording to 2 CFast 2 cards at the same time in RAW allowing higher frame rates; and more.

The Basics of Audio For Video from Shure

Although we seldom think about it, the recording and playback of audio for video involves a series of processes. First, the sound must be captured by a microphone; next it must be recorded on a storage medium; then it must be amplified and played back through speakers or headphones so that it can be heard by a listener. The devices that perform these functions are collectively known as the audio chain.

In the world of professional audio-for-video and audio-for-film the capture, recording, and playback processes are usually handled by different pieces of equipment. Despite continuing improvements in the power and sophistication of audio and video editing software, however, it is usually difficult or impossible to take bad audio and make it good.

To deliver great audio, you must record great audio.

No matter how creative and well-executed the visual aspects of a production may be, and regardless of whether it's posted on YouTube, burned to a DVD or appears on a big, little or mobile screen, the viewer’s experience can be utterly ruined by lackluster audio. To a greater degree than most people realize, sound can “make or break” any video or film project. Using this handy guide from our friends at Shure, you can identify some Shure microphones, monitoring solutions, mixers, and accessories frequently used in audio/video applications.
