A trio of broadcast manufacturers join the OCA Alliance
WORLD: AEQ, CB Electronics and The Telos Alliance have all joined the OCA Alliance (Open Control Architecture). The alliance promotes awareness and adoption of the AES70 standard for open control architectures and its three new members are all broadcast sector technology suppliers.
Marc Weber, chairman of the Marketing Working Group, speaking on behalf of the OCA Alliance noted: ‘The ratification of OCA as AES70 has been a significant influence on traction, both in increasing and widening interest in, and take up of, the standard. OCA (AES70) now offers a promising solution for users of the AES67 audio transport standard, providing uniform connection management. The AES67 standard does not fully specify the rules for making and breaking media stream connections, with the result that not all of today's AES67 products are readily interoperable. AES70 can solve this problem. On top of which, OCA (AES70) can cooperate with a wide variety of other audio transport types, such as AVB/TSN and Dante.’
‘Leveraging networking technology is strong strategy, which is the very reason we invented Livewire, the first Broadcast AoIP protocol, years ago. We believe so strongly in interoperability, we helped drive AES67's development both financially and technically,’ said Telos Alliance CTO Greg Shay. ‘We believe the OCA (AES70) standard is key to furthering the use of network technology in broadcast facilities. By joining OCA, we add our weight to the gathering momentum for using this open, vendor-interoperable standard for control and for the future “Facility Over IP” concept.’
‘For some time though we have been looking for a way forward using Ethernet but could not find a unified control protocol. There is AES67 but it does not define a method by which audio streams are discovered, connected or controlled,’ added Colin Broad, managing director of CB Electronics. ‘This year the AES published the AES70 specification, based on the Open Control Architecture protocol, which can be used to control audio streams and networked audio devices. As a result of discussions with the OCA Alliance, we felt it important to participate in defining the standard. Subsequently CB has commenced a project to develop applications using AES70.’
‘When approaching control protocol compatibility in IP enabled equipment, we observed several proprietary solutions; some open to other manufacturers and others exclusive and closed. We also noticed the group of manufacturers concerned about interoperability for the benefit of users, collaborating in the AES working group X210 that eventually published the AES70 common. We participated as observers in AES X210 and, once the results were published as the AES70 standard, presented our application to become an associate member in the OCA Alliance,’ explained Miguel Sancho, director of R&D at AEQ. ‘Our aim is to actively participate in the alliance, to contribute in the implementation of AES70, to facilitate the integrated control of audio equipment connected through IP networks in broadcast and other professional applications, and to promote the unified control of equipment from different manufacturers via AES70; and to make possible the unified control of previously released equipment, either by AEQ or third party manufacturers prepared to share information about proprietary control protocols.’
‘We are delighted that these influential broadcast companies will now drive OCA (AES70) with us,’ concluded Mr Weber. ‘This is a significant milestone for the OCA Alliance.’
