Abstract

The embodiment of the invention discloses a multilayer signal superposed multi-screen splicing processor and a multilayer signal superposition method thereof. According to the processor and the method, under a condition of satisfying a real time signal transmission demand, a single screen can display more signals; and the technical problem of increasing excessive costs is solved. The multilayer signal superposed multi-screen splicing processor provided by the invention comprises at least one output unit; each output unit is equipped with a first superposition module, a second superposition module and a delay control module; the first superposition module carries out first superposition to the signals transmitted to the output unit; the second superposition module carries out secondary superposition to the signals which are transmitted by the first superposition through cascading loopback and are processed by delaying through a delay control module.

Description

technical field [0001] The invention relates to the technical field of processors, in particular to a multi-screen splicing processor for superimposing multi-layer signals and a method for superimposing multi-layer signals. Background technique [0002] The function of the multi-screen splicing processor is to collect multiple video signals, which are superimposed and spliced ​​and then output to the large screen for display. With the development of display technology, the resolution of a single screen is constantly increasing, from 1400x1050 to 1920x1080, and then to 3840x2160 (4K), so displaying more pictures and more information in a single screen has become a kind of New requirements, such as the current display of 9 signals or 16 signals on a single screen are relatively common usage modes. [0003] A real-time multi-screen splicing processor is usually composed of an acquisition unit, a main control unit, a high-speed serial signal crossover unit, and an output unit. ...
