一种交互录播系统 技术领域
本实用新型涉及多媒体技术领域，具体涉及一种交互录播系统。
背景技术
传统的录播装置和智能交互平板是互相独立的两个设备，两者进行通信时都是通过外部连接，智能交互平板与录播装置连接，录播装置与外围设备(摄像头、麦克风)连接，用户在智能交互平板的带触摸屏的显示器上操作所产生视频信息和音频信息，以及利用麦克风录入的音频信息，摄像头录入的视频信息，都会传送到录播装置进行存储，以备后序工作的进行；以及用户将录播模块将其存储的音频和视频信号传送给显示器进行显示，或者将智能交互平板内部的存储设备的音频和视频信号传送给显示器进行显示。
由于上述设备是相互独立的设备，需要分开控制不利于一体化控制，因此，提出将录播装置与智能交互平板一体化设备，即将录播模块设置在智能交互平板内部，使录播装置受控于智能交互平板，但是由于智能交互平板的显示器仅提供一个音频和视频的输入接口和一个音频和视频的输出接口，因而现有方案无法有效解决视频信号的分配。
