Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] The invention proposes a 512×512 broadcast-level ultra-large-scale 3GSDI matrix, which greatly meets the needs of the broadcasting and security industries for the number of matrix channels. However, 512 inputs and 512 outputs will lead to an increase in the size of the matrix, resulting in a series of problems. One of the design bottlenecks for increasing the size of the matrix is ​​that when the chassis width standard is fixed, the size of the PCB board used as the backplane in the chassis cannot be expanded infinitely. According to the PCB board manufacturing process, the current optimal size of the PCB board is about 12U (1U =44mm), however, a 512×512 ultra-large-scale 3GSDI matrix needs to use a 24U PCB board, which may cause problems such as PCB board ...

Abstract

The invention discloses a 512*512 broadcasting super-large scale 3GSDI matrix. The 3GSDI matrix comprises a signal input processing module, a switching module and a signal output processing module, wherein the signal input processing module is used for performing equilibrium processing and primary clock processing on 3GSDI signals passing by; the switching module is used for achieving switching between 512 paths of input signals and 512 paths of output signals of the 3GSDI signals and cross switching between any path of input signals and any path of output signals; the signal output processing module is used for performing secondary clock recovery processing and signal driving processing on the 3GSDI signals. The 512*512 broadcasting super-large scale 3GSDI matrix can effectively solve the problem of signal loss in the transmitting and switching processes of the3GSDI signals and improve safety and stability of broadcasting matrix equipment, and meanwhile two 12U PCBs are connected to form a 24U PCB structure, so that the problem that the PCBs deform because the size and scale of the matrix are increased is solved.

Description

technical field [0001] The invention relates to the field of video signal processing, in particular to a 512×512 broadcast-level ultra-large-scale 3GSDI matrix. Background technique [0002] The video matrix refers to an electronic device that arbitrarily outputs m-channel video signals to n-channel monitoring equipment through the method of array switching. The common video signal matrix generally has 8×8, 16×16, 32×16, 32×32, 64×32, 64×64, 96×96, 128×128, 256×256 according to the different input and output channels , 512×512 and other specifications, the number before the multiplication sign is the number of input signals, and the number after the multiplication sign represents the number of output signals. [0003] Video matrix is ​​widely used in TV stations, mobile TVs, security monitoring and other equipment. Different industry applications have different requirements on the performance and specifications of the matrix. Broadcast-level video matrix has very high req...
