Fig. 1 is a schematic structural diagram of a video isolation system according to an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 first embodiment.
Fig. 1 is a schematic structural diagram of a video isolation system according to an embodiment of the present invention. The video isolation system comprises a data network server, a video network server, a decoder and an encoder, wherein the data network server and the video network server are in two-way communication through a standard data interface.
In this embodiment, the standard data interface is a serial port or other low-speed standard data interface.
The isolation system works as follows: when a data network needs to retrieve video images of a video network, sending a video request to the data network server, and sending a retrieval instruction to the video network server by the data network server through a standard data interface; after the video network server receives the retrieval instruction, a plurality of decoders are allocated to decode a plurality of video streams into a plurality of single-channel video signals respectively and send the single-channel video signals to the encoders connected with the decoders, the corresponding relations among the video streams, the decoding ports and the encoder ports are sent to the data network server through a standard data rate interface, then the encoders encode the video signals sent by the decoders, and then the data network server provides encoder addresses of videos to be retrieved for video network visitors. In this embodiment, the retrieval instruction may be encrypted or unencrypted, but a signal transmitted by the retrieval instruction is not a data packet of a data network or a video network, so that data packets of different networks can be prevented from penetrating.
In this embodiment, decoding the plurality of video code streams one by one into a plurality of single-channel video signals has the following advantages: the video signal is standard, equipment and information security management personnel can easily verify that the data packets of the video network and the data network are not penetrated by any direct data packet, so that whether the requirement of completely isolating the data packet is met when the video of the video network is called from the data network or not can be easily judged. It is permissible, and conventional, for the encoder within the data network to receive a video signal and generate a video data stream.
In this embodiment, the encoder has an AI identification function. Specifically, for example, the encoder may recognize information such as a human face and a license plate in the video signal, amplify and attach the information to a video stream, so that the key information can still be seen clearly when a low-definition code stream is called by the data network side.
In this embodiment, the encoder has a function of improving the image sharpness by AI. Specifically, for example, a low-definition video created earlier in the video network may be enhanced in visual effect.
In this embodiment, the encoder has an AI frame insertion function. Specifically, for example, a video, an active person, a vehicle, or the like, which is created earlier in the video network and has a lower frame rate, is interpolated to obtain a smoother visual effect of the video.
In this embodiment, the plurality of video signals encoded by the encoder have a plurality of resolutions or a plurality of code rates. The benefits of this are: firstly, video sources on one side of a video network cannot be concurrent for many times; and secondly, when a low-definition signal is needed to ensure fluency (such as network signal difference or software decoding), one side of the data network uses a lower-definition code stream to obtain a fluent video.
In this embodiment, the decoder may decode and splice multiple videos into a single video signal.
In this embodiment, the video network decoder can simultaneously decode multiple video sources and combine them into a single combined video output as required. The benefits of this are: firstly, the requirement of multi-channel video combination can be completed only by transmitting the bandwidth required by one channel of video; secondly, decoding is only needed once, and the occupation of resources such as a decoder, a CPU and the like is small; thirdly, the video is zoomed only once, so that the image quality loss is less; fourthly, the images are zoomed and spliced without calling resources, so that the resource overhead is saved.
In this embodiment, the video signal is any one of video type signals such as an SDI signal, an HDMI signal, and a VGA. The purpose is that for a data network, only a standard video content, not a data packet, enters the network, and a user can judge that the data is isolated.
In this embodiment, the data network and the video network do not have direct or indirect network communication, and there is no direct penetration of data packets.
Example two.

In this embodiment, the video network server identifies and acquires available video resources in the video network in an SDK or industry protocol manner, and sends an available video resource directory to the data network server through a standard data interface. In this embodiment, the available video resources may include, in addition to the video stream, information that can be acquired, such as latitude and longitude of a camera gun, geographic position information, and an ID number, and these data are processed for the second time, and do not belong to a video network, and the data enter a data network, and then the standard data interface is transparent for transmission.
In this embodiment, when the video visitor requests any one of the available video resources in the available video resource directory, the data network server sends a video retrieval instruction to the video network server through the standard interface, the video network server sends the video source address of the video network to the decoder in the idle state after receiving the video retrieval instruction, then the decoder decodes the code stream of the video source into a standard video signal and sends the standard video signal to the encoder corresponding to the data network through a video line, responding to the decoder and the encoder address corresponding to the retrieval instruction of the data network server at the same time, and the encoder decodes the code stream of the video source and provides video stream service, and finally the data network server provides the stream address of the encoder for the video access personnel.
The video signal obtained by the video isolation system and the video signal obtained by the video isolation method are standard, equipment and information security management personnel can easily verify the video signal, and data packets of the video network and the data network are not penetrated by any direct data packet, so that whether the requirement of completely isolating the data packet is met when the video of the video network is called from the data network is easily judged.
Furthermore, the term "plurality" means two or more. While embodiments of the invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
