New concept of digital audio transmission and switching
基於以太網的無中心音頻傳輸和交換技術 -
Cobranet audio network technology is the development trend of audio transmission and switching, as the pace of the broadcast digital and networked development is stepping. cobranet audio network technology transmits and distributes real - time and uncompressed digital audio signal. compared with analog, this technology not only transmits high quality audio, but also economize cost. now many broadcasting stations, gymnasiums and meeting places start to make use of this technology to build their network systems. in order to operate and maintain these networks, network managing software aiming at application will be needed
Cobranet音頻網路技術利用快速以太網傳輸和分配實時、非壓縮的數字音頻信號，在保證傳輸高質量的音頻信號的同時，與傳統的模擬方式傳輸音頻信號相比，大大降低了電纜布線等成本。目前很多廣播電臺、體育中心以及大型會場都開始利用該技術組建自己的音頻網路系統，而要運行和維護這個網路系統，需要開發專門基於cobranet技術的面向應用的網路管理軟體。
