高共享性

  “教育云录播系统”部署位置可位于教委信息中心或学校信息机房。各学校录播教室仅需要布置音视频采集设备,通过教育网接入,录播工作由教育云完成,各学校或各教室动态共享录播资源,大大节约了设备投资,提高了设备使用率。

  高扩展性

  “教育云录播系统”的规模可以动态伸缩,满足应用和用户规模增长的需要。性能动态可调,不受具体设备限制。新增教学录像系统,仅需要在新增教室内增加摄像头、话筒等音视频设备即可,投资幅度大大缩小。

  从 720P 到 1080P 升级更是可以简单配置实现。

  高清晰度

  “教育云录播系统”基于 IP 高清视频技术,起点即为高清视频,并且 720P/1080P
可动态配置,真正的做到一步到位。在教学活动中,高清视频能够带给观看者更加清晰直观的感受。采用先进的音频降噪算法,能够将外部环境干扰降到最低。

  高灵活性

  画面合成路数(例如某个教室摄像路数增加,保存单画面数据)等,分辨率,码率配置即可发生改变。编码方式、格式可动态调整,针对高带宽,低带宽用户,可以发布不同清晰度的视频。

  高可靠性

  “教育云录播系统”使用了数据多副本容错、计算节点同构可互换等措施来保障服务的高可靠性,使用“云法庭”比使用本地计算机可靠。设备集中,便于维护,集中控制,集中管理。

  高经济型

  避免随着技术变革,设备发展,一次次的更新设备,性能改变,不需要更换设备,补充即可。总拥有成本反而降低。尤其是在系统扩展时,教育云录播系统新增一套录播系统的成本为传统方案的三分之一甚至更低。

  高易用性

  教室内设备降到最少,教师上课只有电脑需要操作。可维护性、易用性都大大提升。

目前有一些大厂家在做录播系统,像奥威亚、中庆、北京德威、锐取等,但是这些录播系统的造价相对较高,看你做什么方面了,最近了解到有一家做简易录播设备的厂家,叫大连泛东,所谓简易录播就是能够实现每个教室都变成录播教室,而且不需要重新装修教室,造价低,能够实现录播常态化。

一般是如RHUB这样的 使用起来比较简单 方便,并且直播录播一体
