s110, based on a video transmission network, obtaining candidate video coding data obtained by uniformly coding candidate video resources in at least one format from video coding equipment.
The video transmission network refers to a network dedicated to transmitting video, for example, the video may be transmitted in a wired or wireless manner, and specifically, the video may be transmitted by using a 4G or 5G wireless IP (Internet Protocol) network.
The video coding equipment refers to professional network transmission equipment capable of coding and compressing video resources. In this embodiment, the video encoding device may specifically be an 8000-series network video encoder, and by using this series of video encoding devices, compression processing on aspects such as high compression ratio and high image quality of video resources may be implemented based on an image data compression technology of an h.264 encoding structure.
The candidate video resource refers to a video resource to be processed, and can be acquired by any video source device such as a camera device or a video access device, and the specific video source device may include a mobile phone, a camera, a digital camera, and the like.
In this embodiment, the candidate video resources may be acquired by at least one or at least two video source devices. It is understood that the signal formats of the VIDEO resources obtained by different types of VIDEO source devices are different, and the VIDEO resources may be component, composite, DVI (Digital Visual Interface), HDMI (High Definition Multimedia Interface), SDI (Digital component Serial Interface), S-VIDEO (split VIDEO Interface), and other formats.
Therefore, in the method, in consideration of the multi-format of the obtained candidate video resources, the video coding device performs unified coding processing on the candidate video resources in at least one format to form a unified video code stream, the video management server acquires all candidate video coding data obtained through unified coding from the video coding device, and then the video management server performs selection and cutting processing on all candidate video coding data in a centralized manner.
In this embodiment, the format of the video stream output by the video encoding device may be determined according to actual conditions.
It can be understood that the video display formats in the director system are unified, and the signals in the multiple video display formats are converted into the signals in one video display format, so that the problems of black screen, jitter or static frame in the prior art when the video signals in the multiple formats are selected and cut can be solved, and the video display effect of the director system is prevented from being influenced.

The control instruction may be an instruction instructing the video encoding apparatus to transmit the target video encoded data, or an instruction instructing the video decoding apparatus to transmit the target video decoded data. It is understood that there are various system control commands in the director system for interacting with the devices to complete the final video presentation in the director system.
It can be understood that, by separating the video transmission network and the session transmission network, the video transmission network is specially used for transmitting video and audio data, and the session transmission network is specially used for establishing a session between devices and transmitting a system control command, the smooth transmission of images can be ensured, and meanwhile, the real-time transmission of the system control command can be realized.
