Broadcasters get crucial bridge between SDI, AoIP systems
6 October 2015, Cleveland Ohio, USA
The Telos Alliance® announced today that it is shipping the newest member of its xNode™ family of AoIP interfaces — the Linear Acoustic SDI xNode. For the first time, TV facilities can take advantage of fully distributed I/O and Audio over IP for HD/SD-SDI signals, enabling incredible flexibility in audio routing and distribution.
Notes Marty Sacks, Telos Alliance Vice President of Sales, Support and Marketing, “More and more TV broadcasters are choosing AoIP networks to replace aging TDM and analog plants. The SDI xNode gives them the missing link they’ve been asking for — an easy-to-use device that allows translation of standard and high-definition SDI audio channels to routable, uncompressed AoIP audio streams.”
“The SDI xNode is particularly welcomed by broadcasters operating combined Radio/TV facilities,” Sacks adds. “Until now, radio engineers who wanted to exchange audio between the TV and radio sides of the building had to round-trip it, converting from digital to analog, and back to digital. The SDI xNode eliminates all that. Sharing audio between TV and Radio studios just became easier, by a large order of magnitude. ”
One SDI xNode is capable of de-embedding multiple channels of audio from its dual SDI inputs, taking audio from standard-definition and HD SDI audio channels and translating them to real-time Livewire+™/AES67 audio streams — which can then be routed to destinations through the plant. Livewire®, the broadcast AoIP technology introduced by Telos® in 2003, now powers more than 6,500 broadcast studios worldwide. Livewire+ is completely AES67-compliant, ensuring interoperation with the growing number of broadcast devices that support the AES67 standard.
The SDI xNode is both compact and powerful; two may be racked side-by-side in just one RU. Each SDI xNode manages dual, independent HD/SD-SDI paths, and can de-embed, shuffle, and re-embed up to 16 channels of audio on each SDI path, with full routing of channels between SDI and AoIP I/O on each SDI interface. Compensating video delay for each SDI input maintains audio/video synchronization. Each SDI xNode features a built-in, auto-sensing power supply suitable for use worldwide; an optional external backup power supply is also available to ensure uptime.
The Linear Acoustic SDI xNode is part of the Telos Alliance xNode family, which includes Analog, AES/EBU, Microphone, GPIO and Mixed-Signal versions from sister brand Axia® Audio. They are all equipped with dual-redundant Ethernet ports, and, a redundant power plan which allows operation using either AC or PoE (Power over Ethernet) power sources, with automatic failover.
