the client is used for sending a pre-monitoring request to a video source in a multicast mode and displaying a video signal output by the video processing module;
and the video processing module is used for decoding the video signal input by the video source and sending the decoded video signal to the client.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model provides a pair of video pre-monitoring system, through setting up the video processing module, send to the customer end after decoding the video signal by video source input, make the customer end needn't decode the processing to the video signal, reduced customer end CPU data processing's burden, improved data processing speed, and reduced the network bandwidth requirement. The experiment shows, the utility model discloses a video supervise system in advance can make the display screen reach the speed of 30 frames per second, and the picture quality is clear not stuck. Compared with the prior art that the picture is blocked when about 5 frames per second, the method obviously improves the pre-monitoring effect.
Drawings
Fig. 1 is a block diagram of a video pre-monitoring system according to an embodiment of the present invention.
In the figure: the system comprises a 1-video source, a 2-video processing module and a 3-client.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The embodiment of the utility model provides a video is monitored system in advance, its component block diagram is shown in FIG. 1, the system includes: the system comprises a video source 1, a video processing module 2 and a client 3 which are connected through a network, wherein the number of the video source 1 and the number of the client 3 are all more than or equal to 1; wherein the content of the first and second substances,
the video source 1 is used for outputting an encoded video signal to the video processing module 2 after receiving a pre-monitoring request sent by the client 3;
the client 3 is used for sending a pre-monitoring request to the video source 1 in a multicast mode and displaying the video signal output by the video processing module 2;
and the video processing module 2 is used for decoding the video signal input by the video source 1 and sending the decoded video signal to the client 3.
In this embodiment, the system mainly comprises a video source 1, a video processing module 2 and a client 3 connected via a network. The network may be a fiber optic network or an ethernet network. Although only one video source 1 and one client 3 are shown in fig. 1, the number of video sources 1 and clients 3 may be greater than or equal to 1. Each block is described below.
The video source 1 is mainly intended to provide a digital video signal. The video source 1 can be a personal computer, and a video file is stored in a memory of the personal computer; it may also be an IP camera, also called webcam. The video source 1 can receive the pre-monitoring request instruction sent by the client 3. Different from the prior art, the video source 1 sends the encoded video signal to the video processing module 2 after receiving the pre-monitoring request instruction, instead of directly sending the encoded video signal to the client 3.
The client 3 is mainly used for pre-monitoring the video source 1. The client 3 can be a personal computer, and is configured with a human-computer interaction device (a mouse and a keyboard) and a display device; embedded computers may also be employed. The man-machine interaction equipment is used for realizing various operations, such as sending a pre-monitoring request to the video source 1; the display device is used to display the video signal, i.e. to preview it. The client 3 sends the pre-monitoring request to the video source 1 in a multicast manner, that is, the pre-monitoring request can be sent to a plurality of video sources 1 at the same time. Unlike the prior art, the client 3 directly displays the video signal output by the video processing module 2 without decoding the video source 1 signal. Therefore, compared with the prior art, the CPU data processing load is greatly reduced, and the data processing speed can be improved; and the requirement on network bandwidth can be reduced, so that the display effect is improved.
The video processing module 2 is mainly used for decoding the video signal input by the video source 1 and sending the decoded video signal to the client 3. The video processing module 2 is a module which is specially added in order to improve the pre-monitoring effect in the embodiment. Since the video processing module 2 shares a large part of the data processing tasks originally belonging to the CPU of the client 3, the pre-monitoring effect can be significantly improved. The video processing module 2 generally adopts a special audio/video processing chip.
In this embodiment, when one video source 1 receives pre-monitoring requests from a plurality of clients 3 at the same time, the video source 1 sends encoded video data to the video processing module 2, and the video processing module 2 decodes the video data and sends the decoded video data to the plurality of clients 3 at the same time in a multicast manner. For this situation, the prior art processing method is to send encoded video data from the video source 1 to each client 3, and each client 3 needs to decode and display the encoded video data. In the embodiment, the video source 1 only needs to copy one same encoded video data packet and send the same encoded video data packet to the video processing module 2, the video processing module 2 decodes the encoded video data packet and sends the decoded video data packet to the plurality of clients 3 at the same time in a multicast mode, and the plurality of clients 3 can perform pre-monitoring without decoding. Therefore, the present embodiment can simultaneously reduce the data processing load of the CPUs of the plurality of clients 3, and the effect is more remarkable.
As an alternative embodiment, the video processing module 2 is mainly composed of a haisi 3536 chip.
This embodiment presents an implementation of the video processing module 2. The Hi3536 is a professional high-end SoC developed for multi-channel high definition or multi-channel D1NVR product application. The Hi3536 is internally provided with a high-performance A17 processor and a multi-protocol video decoding engine with up to 16-path 1080p decoding capability, integrates high-performance video/image processing engines of multiple complex image processing algorithms, and provides excellent image quality for client products by combining two-path high-definition display output capability. It should be noted that the present embodiment only provides a preferred implementation of the video processing module 2, and does not negate or exclude other possible implementations.
The above description is only for the description of several embodiments of the present invention, but the scope of the present invention should not be considered as the protection scope of the present invention, in which all the equivalent changes or modifications or the equal-scale enlargement or reduction etc. made according to the design spirit of the present invention should be considered as falling into the protection scope of the present invention.
