本實用(yong)新型涉及(ji)一種會(hui)議系統,尤(you)其涉及(ji)一種高精(jing)度同步會(hui)議裝(zhuang)置(zhi)。
背景技術:
信(xin)息(xi)時代的(de)(de)今天,人們對快(kuai)速(su)的(de)(de)信(xin)息(xi)溝通的(de)(de)要求越(yue)來越(yue)高(gao),從政府(fu)機構的(de)(de)會(hui)議中(zhong)心、指揮中(zhong)心、監(jian)控中(zhong)心、審判法庭(ting)到教育科研環(huan)境的(de)(de)多(duo)(duo)媒體教室、培訓中(zhong)心、學術報告廳(ting),商務環(huan)境的(de)(de)行(xing)政會(hui)議室,星級酒店的(de)(de)多(duo)(duo)功能廳(ting)以至大型的(de)(de)國(guo)際(ji)會(hui)議中(zhong)心,實(shi)時會(hui)議系(xi)統得到廣泛應用(yong)。
實(shi)時(shi)(shi)會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)系(xi)(xi)(xi)(xi)統(tong)(tong)應(ying)用(yong)(yong)(yong)于現(xian)場(chang)環境中,并且對實(shi)時(shi)(shi)音(yin)頻傳(chuan)輸延時(shi)(shi)有(you)嚴格要求。目前實(shi)時(shi)(shi)會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)系(xi)(xi)(xi)(xi)統(tong)(tong)已經(jing)大(da)規(gui)模使用(yong)(yong)(yong)數字化技術,在使用(yong)(yong)(yong)實(shi)時(shi)(shi)會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)系(xi)(xi)(xi)(xi)統(tong)(tong)時(shi)(shi),人(ren)聲通過擴音(yin)系(xi)(xi)(xi)(xi)統(tong)(tong)播放,如果與本(ben)人(ren)的(de)(de)發(fa)言(yan)延時(shi)(shi)超過50毫秒(哈斯效應(ying))就(jiu)會(hui)(hui)(hui)(hui)有(you)明顯的(de)(de)回音(yin),這是在現(xian)場(chang)應(ying)用(yong)(yong)(yong)領域絕對不能接(jie)(jie)受的(de)(de)。而采用(yong)(yong)(yong)數字化應(ying)用(yong)(yong)(yong)必然涉及到AD/DA轉換,這些操作都需要消耗(hao)時(shi)(shi)間,因此線路延時(shi)(shi)必須控制在極短時(shi)(shi)間內。隨著現(xian)場(chang)實(shi)時(shi)(shi)會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)系(xi)(xi)(xi)(xi)統(tong)(tong)的(de)(de)發(fa)展,現(xian)場(chang)會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)系(xi)(xi)(xi)(xi)統(tong)(tong)研發(fa)出一種“手(shou)拉手(shou)”連接(jie)(jie)方式的(de)(de)專業實(shi)時(shi)(shi)會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)系(xi)(xi)(xi)(xi)統(tong)(tong),該系(xi)(xi)(xi)(xi)統(tong)(tong)采用(yong)(yong)(yong)專用(yong)(yong)(yong)線將會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)設備串聯起來,最(zui)后連接(jie)(jie)到會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)主(zhu)機。這種會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)系(xi)(xi)(xi)(xi)統(tong)(tong)主(zhu)要應(ying)用(yong)(yong)(yong)于大(da)型團體會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)交流,可以避免(mian)會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)者眾多而顯得混亂,并且具備靈活(huo)組網,低成(cheng)本(ben)組網等優(you)點,逐漸代(dai)替傳(chuan)統(tong)(tong)會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)系(xi)(xi)(xi)(xi)統(tong)(tong),成(cheng)為現(xian)代(dai)實(shi)時(shi)(shi)會(hui)(hui)(hui)(hui)議(yi)(yi)(yi)系(xi)(xi)(xi)(xi)統(tong)(tong)的(de)(de)主(zhu)流產品。
