A video wall system and its realization method

Abstract

The invention provides a spliced screen system and an implementation method thereof. An inner-loop signal processing chip for converting a specified local audio / video signal received by a local video signal interface into a DP signal is arranged in each splicing unit. On one hand, the DP signal output by the inner-loop signal processing chip is converted into an LVDS signal, and on the other hand, the DP signal is output to a core processing chip of a next splicing unit which is connected with a DP output interface through the DP output interface, so that an internal matrix function of a spliced screen and an echo function of playing back a whole spliced screen display image onto a monitor of a remote control end in real time are realized. Additional separate configuration of a matrix module and a signal distributor module for the spliced screen is not required; convenience is brought to remote control of the spliced screen; the installation cost is lowered; and the defects of frame loss and delay of transmitted signals are overcome.

Description

technical field [0001] The invention relates to the field of public service equipment, in particular to a splicing wall system and an implementation method thereof. Background technique [0002] In the existing traditional splicing wall device, the display terminal of the splicing wall only plays the role of display. It needs to configure a matrix module and a signal distributor module separately on the periphery to put multiple signals to each display terminal of the splicing wall. display; moreover, when the video, image and roaming interface are displayed on the splicing wall, the conventional splicing device cannot display the picture and content of the current splicing wall in real time on the remote monitoring end, which affects the convenience of interactive control and monitoring at the remote control end ; However, devices using network codecs have the disadvantages of high price, image compression, frame loss, delay, and low bandwidth. [0003] Therefore, prior ar...

Problems solved by technology

[0004] In view of the deficiencies in the prior art above, the purpose of the present invention is to provide users with a splicing wall device and its implementation method, which overcomes the fact that the display end of the splicing wall itself does not have a matrix function and an echo function in the prior art, resulting in When performing video splicing and display, the matrix module and the signal distributor module must be configured separately, resulting in the disadvantage of inconvenient use
