BIRTV簡介
◆北京國際廣播電影電視設(shè)備展覽會(BIRTV)是中國最具權(quán)威的廣播電影電視專業(yè)設(shè)備綜合展覽會。從創(chuàng)辦至今的近二十年來,其參展商的數(shù)量,展出展品的先進(jìn)程度、展覽會總面積、參觀觀眾的數(shù)量和專業(yè)程度等在中國同類型展覽會中一直都是最好的。
最好的展覽會
◆每年一屆的BIRTV是中國廣播電影電視展覽會當(dāng)中成功的典范。眾多國內(nèi)外領(lǐng)先廠家都把BIRTV當(dāng)作在中國發(fā)布最新產(chǎn)品、進(jìn)行市場推廣的最重要活動。每年8月,全國各地的廣播電視專業(yè)人士包括各級廣播電視廳、局的管理者和電視臺的用戶組成眾多代表團(tuán)前來參觀;廣播電視研究機(jī)構(gòu)或大學(xué)的教授和學(xué)者;尋求商業(yè)合作伙伴的代理商也紛紛趕來參加BIRTV。在展覽會前一天的主題報告會是總局領(lǐng)導(dǎo)闡述行業(yè)政策、公布行業(yè)發(fā)展規(guī)劃的重要場所,也是業(yè)內(nèi)知名的學(xué)術(shù)交流活動。由各參展廠家舉辦的各具特色的專業(yè)技術(shù)交流會和新產(chǎn)品發(fā)布會也一直深受廣大工程技術(shù)人員的歡迎。因此,BIRTV在把市場需求和產(chǎn)品提供緊密連接的同時,也為業(yè)內(nèi)人士學(xué)習(xí)最新技術(shù)和工具、交流先進(jìn)理念、擴(kuò)大合作、共同探討行業(yè)發(fā)展,營造自身的競爭力提供了一個理想的平臺。BIRTV已經(jīng)成為一年一度中國廣播電視業(yè)的重要約會。
