System and method for monitoring television wall

Abstract

The invention discloses a system and a method for monitoring a television wall, belonging to the technical field of monitoring technology. The system comprises a plurality of video signal sources, a signal receiving device, a signal processing device, a transmission device and a television wall display unit, wherein the video signal sources are used for generating one or more paths of video signals; the signal receiving device is used for receiving the one or more paths of video signals via network; the signal processing device is used for identifying manufacturers corresponding to the video signal and decoding according to a decoding library of the manufacturer to generate YUV signals corresponding to the video signals; the transmission device is used for transmitting the one or more paths of YUV signals generated by the signal processing device to the corresponding television wall display unit; and the television wall display unit is used for displaying the received YUV signals. The invention ensures that the video signals of the monitoring device of different manufacturers can be decoded and displayed without a plurality of special decoding cards, lowers the system complexity and reduces the system volume.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a video wall monitoring system and method. Background technique [0002] When large-size, high-resolution image information display is required in public information display and monitoring display systems, and standard display devices cannot meet this demand, there is such a solution in display system engineering: multiple display units neatly Stacked and spliced ​​together to form a display wall structure similar to a brick wall, a TV wall is produced. [0003] At present, the video wall monitoring system has been widely used in the fields of public security, roads, electric power, security and so on. The intuitive display and convenient control of the large screen greatly increase the work efficiency. In different monitoring fields, the focus of the large screen display is different. Some mainly display video signals, while others are computer signals. [0004] Usually, su...

Problems solved by technology

In the prior art, a decoding card can only decode the video data of the manufacturer's image signal source, but in practical applications, users may choose different manufacturers' monitoring equipment (ie, image signal source), so multiple The decoding card will undoubtedly increase the system cost and equipment volume, and increase the difficulty of equipment installation
