[0054] Example 1:
[0055] In the live recording and broadcasting system, the remote control device is a remote control containing at least three buttons. The three buttons are the video switch button, the scene selection button and the screen confirmation button. The video switch button corresponds to the video switch unit of the remote control device and the scene selection button. Corresponding to the scene selection unit of the remote control device, the screen confirmation button corresponds to the recording unit of the remote control device.
[0056] After entering the network director, you can switch the video source of the director screen by using the video switch button of the remote control. When it is necessary to quickly call the camera preset camera position to realize the shooting of the preset scene, the user can first use the video switch button to select the camera screen, and then use the scene selection button to quickly switch the camera preset camera position. ...

[0059] Example two:
[0060] Figure 4 It is a schematic structural diagram of a live recording and broadcasting system according to an embodiment of the present invention, such as Figure 4 As shown, the live recording and broadcasting system includes a guiding system, a streaming media server 202, a cloud platform 405, a local recording device 203, and a storage device 406. Among them, the guide system includes a guide station 102, 3 cameras 101, a courseware display device 401, a guide keyboard 402, a guide monitor 403, an audio device 404, and a remote control device 103, 3 cameras 101, a courseware display device 401, a guide keyboard 402, The guide monitor 403, the audio device 404 and the remote control device 103 are respectively connected to the guide station 102. The director station 102 is the core equipment of the director system. It adopts a multi-core and multi-CPU high-performance embedded architecture. The software is developed based on the Linux+Android dual syst...

[0071] Example three:
[0072] Figure 5 It is a schematic diagram of a video data flow of a guiding system according to an embodiment of the present invention, Figure 5 VI is the video input, VPSS is the video processing, VENC is the video encoding, VDEC is the video decoding, and VO is the video output.
[0073] reference Figure 5 , By inputting three channels from outside the director station, the uncompressed high-definition video data of the camera plus the uncompressed high-definition courseware video stream sent by a desktop / laptop, a total of four channels of high-definition uncompressed video data exist in the director station at the same time. In addition, the director station also receives a way of compressed and transmitted video data from the network or local mobile terminal wireless projection, and decodes and restores it in the director station. It can be seen that there are a total of five channels of video data candidates in the director station for director s...
