Photoelectric module one-into-many system for image video transmission broadcasting system

Abstract

The invention relates to the technical field of information transmission, and discloses a photoelectric module one-into-many system for an image video transmission broadcasting system. The photoelectric module one-into-many system comprises an optical splitter, an HDMI input end is fixedly connected to a right side of the optical splitter, a transmitting optical module is fixedly installed in theoptical splitter, an output interface is fixedly connected to a left side of the optical splitter, and an optical fiber transmission line is inserted in one side of the output interface away from theoptical splitter. According to the photoelectric module one-into-many system for the image video transmission broadcasting system disclosed by the invention, an electrical signal is converted into anoptical signal, broadcast one-into-many is performed on an optical path, a transmitting end first converts the broadcast into the optical signal, and directly divides the optical signal into multiplecopies with equal energy or unequal energy through an optical splitting chip, for example, one-into-two, one-into-four, one-into-eight and the like, a receiving end at the next node restores the optical signal into the electrical signal by using a photoelectric conversion module, so that the system function of broadcast one-into-many is achieved.

Description

technical field [0001] The invention relates to the technical field of information transmission, in particular to a photoelectric module one-point-multiple system for image and video transmission and broadcasting systems. Background technique [0002] The image and video transmission one-to-multiple system refers to copying multiple copies of the same image and video signal at the sending point of the signal transmission and sending it to the next node. In essence, this is a broadcast system, that is, a one-to-many broadcast system. It belongs to a mathematical topology. Optical signal transmission refers to transmitting the optical signal sent by the laser to the optical fiber through the optical device, then transmitting it to the receiving end through the optical fiber, and then converting the optical signal to the photodetector through the optical device. In this way, the signal is transmitted in the optical fiber, and the purpose of improving the transmission rate, capa...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a photoelectric module one-point-multiple system for image and video transmission and broadcasting systems, which has the advantages of low cost, low power consumption, improved mass production and applicability, and solves the problem of traditional image The video one-to-multiple system is transmitted by an electric chip. Usually, this electric chip is not a general-purpose chip because it involves some different protocols, so the cost will be high, which is not conducive to mass production. In addition, the power consumption requires There are requirements, and due to the natural limitations of the electronic chip, under many protocols, it is impossible to directly achieve a system of more than 1 to 8, or even 1 to 4, which increases the huge cost, power consumption and circuit board area.
