Problems solved by technology

[0005] At present, the video monitoring systems on the market use a single channel for transmission, that is, a monitoring device can only use one channel for transmission. This method will cause a large delay in the transmission of images with a large amount of information.
Moreover, the transmission speed of traditional single-channel transmission has been difficult to meet the requirements of real-time transmission of ultra-high-definition video images

Embodiment Construction

[0052]The invention discloses a sub-system for multi-channel transmission of ultra-high-definition video images. The sub-system performs encoding and other processing on the video images and simultaneously transmits them through multiple transmission channels, and receives the video transmitted through the multiple channels at the video receiving end. The signal is processed and decoded to complete high-speed, multi-channel transmission of ultra-high-definition video images.

[0053] Such as figure 1 Shown is a schematic structural diagram of a multi-channel transmission subsystem of an ultra-high-definition video image in the present invention.

[0054] The multi-channel transmission subsystem 100 for ultra-high-definition video images (hereinafter referred to as the subsystem 100 ) is connected to an image acquisition module 200 for acquiring ultra-high-definition video images. After the image acquisition module 200 acquires an ultra-high-definition video image, it sends th...

Abstract

The invention discloses a multichannel transmission subsystem and method of a superhigh-definition video image. The subsystem is connected with an image acquisition module for acquiring the superhigh-definition video image, and comprises a video sending end, a video receiving end and multiple transmission channels connecting the video sending end with the video receiving end. The video sending end receives the superhigh-definition video image, performs image processing and coding compression, splits the compressed superhigh-definition video image into multiple sub-images according to set parameters, respectively packs each sub-image according to one or more transmission protocols selected by the set parameters, and respectively sends data packets to the transmission channels corresponding to the transmission protocols, and the multiple transmission channels simultaneously carry out transmission, wherein each sub-image is corresponding to one transmission protocol. The video receiving end receives the data packet transmitted by each transmission channel, and performs image processing and decoding according to the transmission protocol corresponding to each transmission channel so as to restore the superhigh-definition video image.

Description

technical field [0001] The invention relates to the field of ultra-high-definition video transmission, in particular to a multi-channel transmission subsystem and transmission method of ultra-high-definition video images. Background technique [0002] At present, the domestic video image level has gradually begun to transition from standard definition to high definition and full high definition, and high definition video is undoubtedly the current development direction. Compared with high-definition video, UHD is undoubtedly a more challenging technical indicator, and it is also the general trend of future technological development. Ultra-high-definition images have attracted widespread attention from the society because of their extremely high resolution and incredibly delicate display effects, but the amount of image information that follows is also huge. The transmission rate of traditional single-channel transmission It has been difficult to meet the requirements of ult...
