    • A video camera privacy lock is set forth. The video camera privacy lock includes a low level filter driver that install and maintains a first position in a filter graph. The filter driver provides a locked media signal to the next sequential item rather than to a media stream until and unless the filter is unlocked. The locked media signal may be a blank screen, a text message, an icon, a static image (such as an avatar, a photograph, etc., pixilated video, or some other predetermined output). Also, in various embodiments, the driver is locked by default, thereby increasing user trust that the video camera only transmits a media signal when desired.
    • 阐述了摄像机隐私锁。 摄像机隐私锁包括一个低级过滤器驱动程序,用于在过滤器图形中安装和维护第一个位置。 过滤器驱动程序提供锁定的媒体信号到下一个顺序项,而不是媒体流,直到和除非过滤器被解锁。 锁定的媒体信号可以是空白屏幕,文本消息,图标,静态图像(例如头像,照片等,像素化视频或一些其它预定输出)。 此外,在各种实施例中,默认情况下驱动程序被锁定,从而增加用户的信任,即当需要时摄像机仅发送媒体信号。
