Description

一种高清视频多媒体信息叠加器
本申请是以申请号为201910642728.7、申请日为2019年7月16日的中国专利申请为基础，并主张其优先权，该申请的全部内容在此作为整体引入本申请中。
技术领域
本申请涉及一种叠加器，尤其是指一种高清视频多媒体信息叠加器。
背景技术
视频字符叠加器是一种在视频AV信号中叠加字符信息，使得电视图像中叠加有任一字符集或图形的设备，用于显示日期时间、设备号、传感器信息、相关数据等内容。
目前，视频字符叠加器可分为模拟视频字符叠加器和高清视频字符叠加器。模拟视频字符叠加通常采用专用芯片来处理，网络高清视频的字符叠加通常采用向网络摄像机发送OSD叠加命令来实现。随着网络高清摄像机大面积推广和应用，网络高清摄像机逐步取代传统的模拟摄像机，因此针对网络摄像机视频的字符器也得到了广泛的应用。
但是，市场上现有的网络视频字符叠加器采用的方法主要是通过向网络摄像机发送特定的命令来实现字符叠加。由于网络摄像机厂家、品种比较多，设备账号密码及叠加协议各不相同且不对外开放，为了在视频中叠加字符，需要通过网络抓包来分析各家设备特性，一旦设备的配置和协议发生了改变，则需要重新分析设备特性并且需要修改字符叠加器的相关程序才能重新进行字符叠加。现有技术中的这种方法大大限制了在不同网络摄像机中进行视频字符叠加的适应性和可靠性。
而目前市场上字符叠加器和视频信号的存储，并未有所关联，只是完成简单的叠加动作，同时市场上也不仅仅满足于字符叠加，希望可以支持：字符、图形、音频、控制信号等。不仅如此，传统的叠加器只能是接入模拟视频信号或网络视频信号，两者不能同时接入。而在用户的实际环境中，模拟视频信号和网络视频信号同时存在的情况很多，在这样的环境中就需要用到两种不同类型的 叠加器才可以解决用户的问题。
