BIRTV简介
◆北京国际广播电影电视设备展览会(BIRTV)是中国最具权威的广播电影电视专业设备综合展览会。从创办至今的近二十年来,其参展商的数量,展出展品的先进程度、展览会总面积、参观观众的数量和专业程度等在中国同类型展览会中一直都是最好的。
最好的展览会
◆每年一届的BIRTV是中国广播电影电视展览会当中成功的典范。众多国内外领先厂家都把BIRTV当作在中国发布最新产品、进行市场推广的最重要活动。每年8月,全国各地的广播电视专业人士包括各级广播电视厅、局的管理者和电视台的用户组成众多代表团前来参观;广播电视研究机构或大学的教授和学者;寻求商业合作伙伴的代理商也纷纷赶来参加BIRTV。在展览会前一天的主题报告会是总局领导阐述行业政策、公布行业发展规划的重要场所,也是业内知名的学术交流活动。由各参展厂家举办的各具特色的专业技术交流会和新产品发布会也一直深受广大工程技术人员的欢迎。因此,BIRTV在把市场需求和产品提供紧密连接的同时,也为业内人士学习最新技术和工具、交流先进理念、扩大合作、共同探讨行业发展,营造自身的竞争力提供了一个理想的平台。BIRTV已经成为一年一度中国广播电视业的重要约会。
