Echo method and device of distributed splicing processor

Abstract

The invention belongs to the technical field of processors, and particularly relates to an echo method and device of a distributed splicing processor, and the distributed splicing processor system comprises an output node, a network switch and a management host. The system is characterized by further comprising an echo server, the output node is connected with the network switch, and the network switch is connected with the management host and the return display server. The echo server is used for calculating a signal scaling ratio according to the resolution of the actual physical wall and the resolution of the whole wall echo, and calculating the size of the signal displayed on each physical wall under a whole wall echo picture according to the scaling ratio. According to the scheme, theproblem of non-synchronization when the signal crosses the output node in the existing scheme can be overcome, and independent amplification and echo of a certain path of signal can be realized.

Description

technical field [0001] The invention belongs to the technical field of processors, and in particular relates to an echo method and device for a distributed splicing processor. Background technique [0002] Whole wall echo and signal preview are essential functions required to realize the visual control of the splicing processor, that is, WYSIWYG applications, which can maximize customer experience and interaction. For distributed splicing processors, since the signals are all network signals, signal preview becomes very simple. [0003] figure 1 It is a system architecture of a distributed splicing processor in the prior art, and its core is an output node, a network switch and a management host. In the traditional echo mode, each output node encodes and compresses its own output according to its splicing position and the resolution of the entire wall echo, and then transmits it to the management host. Take 2×3 splicing and the whole wall echo resolution as 1920*1080 as a...

Problems solved by technology

[0004] Since the core function of the output node is network decoding and display output, its performance in network encoding is relatively weak, and the encoding output frame rate is low, so the frame rate of the entire wall echo, that is, the refresh rate is low

In addition, due to the lack of synchronization mechanism between output nodes when network coding is performed between each output node, coupled with network fluctuations during data exchange, the management host receives inconsistencies in the output screens of each output node at the same time, which is reflected in a When the signal spans multiple output nodes, when echoing, the output of the two output nodes at the same time is not the same picture
