Livewire+ is an audio-over-Ethernet system that was created by Axia Audio, a division of The Telos Alliance. The original Livewire was introduced in 2003. Its primary purpose is routing and distributing broadcast-quality audio in radio stations. Livewire is interoperable with other RAVENNA standards-based systems and equipment. Livewire was superseded by Livewire+, which enables full AES 67 interoperability. Designed as a superset of functionality utilizing common protocols and formats, Livewire+ is available as an open standard through Axia's Livewire+ Partner Program. To date, there are over 80 Livewire+ Partner companies. Over 6,000 studios have been installed with Livewire+ worldwide, and there are over 60,000 individual Livewire+ devices in the field.〔(【引用サイトリンク】title=Axia Livewire+ Partners )〕 ==History== Before the advent of Livewire, the infrastructure of analog radio plants consisted of miles of multiconductor audio cable wired to walls full of punch blocks at each end. Installation and maintenance was time consuming and expensive. Telos founder and president Steve Church set out to find a better way. He looked to computer networks for inspiration. If data could be divided into packets and routed on a single Ethernet cable, why couldn't the same thing be done with broadcast audio? There were many hurdles, such as latency, lost packets, and prioritizing audio over other traffic on the network. One by one, these and other problems were solved. The theory was put into practice, and workable products were developed.〔(【引用サイトリンク】title=Steve Church Remembered )〕 Livewire made its debut in 2003 at the NAB Show in Las Vegas. The original Liveweire-capable products included the SmartSurface console, Studio Engine, analog, AES, mic and GPIO nodes, as well as the Router Selector node.〔Personal communication, Clark Novak, The Telos Alliance, 30 July 2015〕 The NAB premiere of Livewire marked the dawn of Audio over IP (AoIP). The concept caught on, and before long, other manufacturers were making their own AoIP broadcast equipment. Soon, there developed the need for a standard so AoIP gear from different manufacturers could communicate with each other. Telos worked with other manufacturers to develop the AES67 standard for AoIP interoperability. The Telos Alliance is a founding member of the Media Networking Alliance, which promotes adoption of the AES67 standard on behalf of the pro audio industry.〔http://www.medianetworkingalliance.com/〕 Livewire+ was developed to bring the original Livewire protocol into AES67 compliance. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Livewire (networking)」の詳細全文を読む スポンサード リンク
