发明名称 Advanced video camera privacy lock
摘要 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.
