Description

Technical Field

[0001] The utility model belongs to the technical field of network video monitoring systems, in particular to a device which uses an HDMI encoder to realize an embedded decoder video browsing function and adds a video playback function in a network high-definition video system. Background Art

[0002] In the existing network high-definition video system, network switches, network video recording systems (NVR), four-way decoding + four-screen synthesizers, displays and control systems are usually used. These components work together to achieve the transmission, decoding, synthesis and display of video signals. However, the existing system often only supports the display of real-time video signals, and there is no effective solution for the demand for video playback function. Therefore, those skilled in the art provide an embedded decoder playback video function enhancement device based on HDMI encoder to solve the problems raised in the above background technology. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an embedded decoder playback video function enhancement device based on an HDMI encoder, including an HDMI encoder, a network switch, a network video recording system (NVR), a four-channel decoding + four-screen synthesizer, a display and a control system. The HDMI encoder receives the video signal output by the network video recording system (NVR), encodes it into a network video signal, and outputs it to the network switch.

[0004] Preferably: an HDMI encoder is added to the network high-definition video system, the HDMI encoder encodes the video playback signal into a network signal and connects it to a network switch, and the network switch distributes the received network video signal to each four-channel decoding + four-screen synthesizer.

[0005] Preferably: the four-channel decoding + four-picture synthesizer decodes and synthesizes the received network video signal into a single / four-picture video signal, and outputs it to the display for display.

[0006] Preferably: the control system controls and manages the entire device to achieve switching and display of the video playback function.

[0007] Technical effects and advantages of the utility model:

[0008] The utility model uses an HDMI encoder to encode the video signal of the network video recording system (NVR) into a network video signal, and distributes it to each four-way decoder + four-screen synthesizer through a network switch, so as to realize the display of the video playback function on any display. This design not only improves the flexibility of the system, but also reduces a dedicated display for video playback, making the video playback function displayed on any display more convenient and efficient.

The HDMI encoder receives the recording signal output by the network video recording system (NVR), encodes it into a network video signal, and outputs it to the network switch. The network switch distributes the received network video signal and the network video signal output by other cameras to each four-channel decoder + four-screen synthesizer. The four-channel decoder + four-screen synthesizer decodes the received network video signal and synthesizes it into a four-screen video signal, which is output to the display for display. The control system controls and manages the entire device to realize the display of network camera images and the display of video playback images.

[0012] The working principle of the utility model is:

[0013] The utility model uses an HDMI encoder to encode the video signal of the network video recording system (NVR) into a network video signal, and distributes it to each four-way decoder + four-screen synthesizer through a network switch, so as to realize the display of the video playback function on any display. This design not only improves the flexibility of the system, but also reduces a dedicated display for video playback, making the video playback function displayed on any display more convenient and efficient.
