The RTSP protocol is mainly used in the data transmission of network video and audio. Most of the ip cameras on the market are RTSP senders, most of the video servers are simple receivers and senders, and most of the NVR devices are receivers, and the analysis is basically a single camera. monitoring signal
[0003] There is also a remote monitoring function in the multimedia field, but only the remote desktop VNC protocol and other methods are used to transmit audio and video signals. The application of the VNC protocol has certain limitations. In the current era of advanced information, in addition to these intelligent systems, we need to monitor many objects, but many places often cannot install surveillance cameras anywhere, because this will lead to a great increase in manpower and material resources. Frequently used computers, or some Android devices, etc., users often need to transmit desktop information and audio at the same time, but the VNC protocol is difficult to meet
Therefore, in the field of security or in the field of video and audio transmission, there is still a lack of a highly adaptable product or transmission interconnection method. One can not only monitor signals, but also multimedia audio and video data such as computer windows, Android device desktops, etc. conveniently and quickly. Products that are sent and can be displayed on the display

The present invention proposes a method and device for data transmission and interconnection among multi-platform integrated devices, including: collecting video and audio output signals; decoding the video and audio output signals and storing them in memory; The final video and audio signal is written into an output signal conforming to the RTSP protocol for output; the output signal is displayed on the display device. The present invention proposes a method and device for data transmission and interconnection between multi-platform integrated devices that can conveniently and quickly transmit multimedia audio and video data such as desktops of PCs and Android devices.
Description
technical field [0001] The invention relates to a data transmission and interconnection method and device between multi-platform integrated equipment. Background technique [0002] RTSP (RealTimeStreamingProtocol), real-time streaming protocol, is an application layer protocol in the TCP / IP protocol system. RTSP is a multimedia streaming protocol used to control audio or video, and allows multiple simultaneous streams to be controlled on demand. The RTSP protocol is mostly used in security field cameras to transmit audio and video signals to realize remote monitoring. The RTSP protocol is mainly used in the data transmission of network video and audio. Most of the ip cameras on the market are RTSP senders, most of the video servers are simple receivers and senders, and most of the NVR devices are receivers, and the analysis is basically a single camera. monitor signal. [0003] There is also a remote monitoring function in the multimedia field, but only the remote desktop...
