All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The design concept is as follows:
and the network video decoder outputs the network video stream to the hardware video conference, and the video encoder encodes the video stream of the hardware video conference into the network stream and outputs the network stream to other systems for calling. For video monitoring, the network video stream is provided by the video monitoring system, and can be directly pushed to a hardware video conference; other video streams requiring physical isolation, such as matrixes, satellites and the like, can also realize a video interworking function through a network encoder and decoder pair.
The first embodiment is as follows:
