The Wireless Speaker and Audio Association (WiSA Association, Sunnyvale CA), founded in 2011, has created a Technical Advisory Committee (TAC) and associated Special Interest Groups (SIGs) to advance the development of wireless audio solutions for home theater, consumer electronics and professional AV markets. Participation in both groups is open to members of the association and the activities pursued by each group may influence the WiSA Compliance Test Specification (CTS) as well as the technology roadmap.
The Technical Advisory Committee will work with other standards bodies such as the IEEE, AES, HDMI and MHL to advance wireless HD audio in their respective specifications. Special Interest Groups will address various challenges facing the audio industry today, such as DTV applications, 802.1 AV bridging, interoperability with other radio technologies and other topics. The focus of the first two Special Interest Groups is on addressing DTV connectivity and multi-room wireless HD audio technology.
“We are at a pivotal point in time for providing leadership and new direction for the wireless speaker and audio industry, and we welcome the participation of Technical Advisory Committee and Special Interest Groups members in charting the course for wireless HD audio in the home theater,” said Jim Venable, President of the WiSA Association. “The WiSA Association has gained significant momentum with the recent release of the industry’s first Compliance Test Specification for interoperability, and I expect our engagement with the Technical Advisory Committee and Special Interest Groups to be equally ground-breaking in driving additional areas of application for high-performance wireless audio.”

Contemporary Research introduces the ATSC+SDI HDTV Tuner

Contemporary Research introduces the ATSC+SDI HDTV Tuner, the first HDTV tuner with built-in broadcast-quality HD-SDI, shipping now.
By directly outputting HD-SDI instead of using an HDMI/SDI adapter, the SDI stream can include 708/608 captioning data, and can be switched to provide stereo AES or AC-3 audio.The HD-SDI video outputs at a fixed resolution (i080i, 720p, or 480i) using an internal scaler for analog and digital channels. In addition to the SDI, AV is sent simultaneously from Component and Composite video outputs, as well as digital coax/optical and stereo audio ports.
Based on the new 232-ATSC+1 platform, the ATSC+SDI is controllable via Ethernet, an onboard Web page, USB, RS-232 and IR control. Programming can be received using cable, off-air, analog, QAM and ATSC standards. An optional A/B RF switch can automatically switch between cable and off-air feeds, supporting a channel list for both inputs. A new digital tuning section enables better response for marginal channels.
The compact HDTV tuners can be mounted two-across within a single rack space.
Contemporary Research President Scott Hetzler says, "This product was created in response to requests from our integrators, consultants, and end users. HD-SDI is fast becoming the professional standard for HD video distribution, traditionally for TV stations and studios, and gaining popularity in corporate, worship, and sports facilities. We added Web control specifically for our broadcast users, who will no longer need control systems and extra interfaces to control their tuner."

The Audio Engineering Society (AES, New York NY) and the OCA Alliance (Bothell WA) have founded an AES standards project to consider OCA, the Open Control Architecture, for a public standard for control and monitoring of professional media networks. The goal of this project, identified as AES-X210, “Open Control Architecture (OCA),” is to produce a public, open and royalty-free communications protocol standard for reliable and secure control and monitoring of interconnected audio devices in networks of two to 10,000 elements. When the standard is complete, it is hoped that OCA will find broad acceptance in the media systems industry and open a new era in standardized, interoperable control of devices from diverse manufacturers.
OCA will be a control and monitoring standard, not a media transport standard, the organizations report. It is intended to operate seamlessly with a wide range of media transport standards such as AES-X192, “High-performance streaming audio-over-IP interoperability” (currently in development) and IEEE AVB. Together, these standards will offer a path to complete network application solutions for future media networks that include both media transport and system control functionality.
OCA is substantially based on work done in the early 1990s by the AES24 project, a pioneering effort in network system control. Although AES24 never reached full standards status, it offered a number of advanced concepts that have found their way into various developments over the years.
In the coming months, the AES-X210 task group, part of AES working group SC-02-12 on Audio Applications of Networks, will be meeting to render the current OCA 1.1 specification into standards form and to shepherd its processing through the AES’s open standards process. Interested individuals are encouraged to participate. The full standards participation policy is available from the AES Standards website. During this period, the OCA Alliance will undertake various initiatives to support the work of AES-X210, and to define proposals for future extensions to the standard.

Crystallizing the focus of the new alliance, AES Standards Committee Chair, Bruce C. Olson remarked, “AES Standards has been deeply involved with standards for digital audio since starting work in 1977. The AES-X210 project to standardize OCA takes us to the next important milestone by integrating control with transport of audio over a variety of networks. Combined with a number of other projects in this exciting area of audio, the AES continues to lead the world in audio standards, which enable a thriving marketplace for compatible products from competing manufacturers. We are very pleased to collaborate with the leading manufacturers in the OCA Alliance on this standards project.”


TV One’s new CORIO®master, C3-540 Series Video System

The new C3-540 CORIO®master offers a new, more efficient approach to building video systems. Using  TV One's latest CORIO®3 technology, it gives the user access to new levels of video processing power to achieve new heights of creative and dynamic  video displays. All this is possible in one 4RU chassis.

The C3-540 combines edge blending, video wall processing, multiviewing, windowing, image warping, and video processing with Up, Down, and Cross Conversion in one device. The combination of multiple products into one 4RU unit results in lower rack space, cable, and power requirements with the unit itself consuming very low power. Additionally a high quality modular video matrix is built in using CORIO®softswitch, which provides an industry first firmware based video routing, switching and video conversion and effects platform using multiple canvases and layouts along with PC and Apple compatible control software. 16 AV universal module slots are available and the CORIO®master automatically recognizes the modules inserted as an input or output module. Any analog or digital format from composite video to 3G-SDI is accommodated.

3M New Ventures (3M’s corporate venture organization, Munich, Germany) and Mersive (Denver CO), a provider of visual computing software, have signed a strategic development and equity agreement that will bring a new class of displays that foster visual collaboration to a broad range of customers, according to the companies. “Advances in graphics processing technology are resulting in the creation of more pixels than ever before,” said Mersive CEO Rob Balgley. “However, viewing more pixels in the form of visual data is often constrained by either inadequate display systems or the high cost and complexity of currently available systems. He added, “Coupling our software with 3M projection and display technology will transform how visual data is used to creatively collaborate, interact and make decisions.”
Central to the strategic development agreement are Mersive’s Sol software, which automatically aligns multiple projectors into one seamless image without the expense of specialized hardware and services, and Solstice software, a new media sharing and display management software that transforms how displays fit into IT infrastructure. Solstice enables multiple users with diverse devices to wirelessly access any display in real time.
