    視頻會議系統解決方案

         

           隨著信息技術的飛速發展,國內網絡現狀得到極大的改善。從國內信息化發展的情況來看,國家級骨干網、寬帶城域網、接入網以及專網的不斷建設和完善,為數據、視頻、語音等多業務的綜合傳輸和融合應用提供了方便可靠的平臺。

           學校的數據、視頻、語音等業務主要依托于互聯網應用。目前,各運營商為學校用戶提供的豐富的網絡接入解決方案:光纖、VPN、ADSL等等,通常512K的ADSL線路可為用戶提供下行512K、上行384K的網絡條件,1M及以上的ADSL線路則可提供更為優良的網絡接入。這樣的網絡條件完全可以滿足視音頻通信的需要。

           面對新的溝通需求,原有的電話、計算機等通信系統已不能完全適應,基于交互式多媒體通信技術的視頻會議正迅速成為企業重要的溝通手段。視頻會議以身臨其境的可視化遠程交流方式替代傳統的電話、E-Mail及異地出差,能夠以更高的效率和更低的成本,滿足集中式管理的需求,讓企業在瞬息萬變的競爭環境中贏得先機,實現持續、快速、高效的整體運營。

           基于對學校未來發展的深刻了解,以及多年服務各類普教高教用戶所積累的豐富經驗,視頻會議系統是用戶最好的選擇,將全新的溝通方式引入校園的教學、管理、服務等各個環節,幫助校區之間的相互溝通。

    系統特點:

    1. 多點會議:內置多點MCU功能,一方面提供多點的MCU功能,一方面提供主會場視頻會議終端功能。各遠程機構根據會場大小及應用選配合適的視頻會議終端,實現分支機構會場的接入。
    2. 異地直呼:通過遙控器進行撥號即可實現點對點呼叫,隨時實現面對面的溝通。
    3. 多畫面合成和混音:系統支持畫面合成和智能混音。畫面合成有1+1、1+2、1+3、1+4等多種形式,配合智能混音可以實現會議討論,達到身處同一會議室的效果。
    4. 雙流功能:系統支持標準的H.239雙視頻流協議,可以把兩路圖像同時傳到遠端。通過雙流功能,可以把培訓老師的圖像和課件資料同時送到遠端,增強培訓的生動性、實時性,實現遠程培訓。
    5. H.264G.722.1 Annex C/Polycom® Siren14TM:系統支持最新的H.264視頻編碼格式,可以在200K左右的帶寬下實現清晰的圖像質量,配合G.722.1 Annex C/Polycom® Siren14TM音頻編碼格式,保證了優質的視音頻效果,充分滿足低帶寬下的會議需求。
    6. 電話接入:系列終端具備電話接入,出差人員可通過普通電話機或手機參加會議,收聽會議并進行會議發言。
    7. 橫幅和字幕功能:MCU和終端具備豐富的字幕功能,字幕位置、顏色、形式、字體等可動態設置。可應用于會議通知,傳達會議要求和重要事宜。
    8. 穿防火墻、NAT:系統內置網守、防火墻/NAT穿越功能,可以解決私網終端接入會議的問題。系統支持ADSL、VPN、專線等多種接入方式,組網靈活。
    9. 多網段接入:具備兩個網口,可提供支持公網、私網混合組網,無論是公司內部終端還是來自Internet的會議終端均可接入系統。
    10. 智能丟包重發、QOS、帶寬自適應:系統具備獨有的智能丟包重發機制、完善的QoS機制和帶寬自適應能力,可以充分適應復雜的互聯網網絡環境,在惡劣的網絡環境下提供優質的視音頻質量。
    11. 高穩定性、高安全性:本方案設備均基于嵌入式架構,穩定可靠;內置防火墻,充分保證會議系統安全;高達128位的AES加密機制保證了視音頻數據流在網絡上傳輸的安全。
    12. 易操作、易維護:視頻會議系統具備良好的人機界面,控制平臺和終端OSD菜單均采用全中文、圖形化界面,操作簡便、極具人性化。
