Low-speed signal photoelectric conversion module of universal multimedia interface
First Claim
1. A low-speed signal photo-electric conversion module of universal multimedia interface, comprising:
- a protocol analysis module configured to analyze half duplex signals in various multimedia control protocols according to protocol specifications of multimedia control signals, determine a signal direction related to the protocol, convert a low-speed signal of a multimedia interface to a full duplex signal, and send the full duplex signal to a packing and encoding module, or perform protocol analysis again on a full duplex signal outputted by an unpacking and decoding module and obtained through protocol analysis to recover the half duplex signal, and then send the half duplex signal to the multimedia interface;
the packing and encoding module configured to pack a full duplex signal of the multimedia interface and a full duplex signal converted from a half duplex signal through protocol analysis, encapsulate all multimedia interface low-speed control signals of the same moment in a frame format, and send the encapsulated signals to an electric-photo conversion module;
the electric-photo conversion module configured to convert an electric signal to an optical signal and send the optical signal via an optical fiber;
the unpacking and decoding module configured to perform frame unpacking and decoding on a received high-speed electric signal, convert the signal to a low-speed signal, directly send a full duplex signal in the low-speed control signal to the multimedia interface, send a full duplex signal obtained through protocol analysis to the protocol analysis module for protocol analysis again to recover the half duplex signal, and send the half duplex signal to the multimedia interface after the signal direction is determined; and
a photo-electric conversion module configured to receive an optical signal sent via an optical fiber, convert the optical signal to an electric signal, and send the electric signal to the unpacking and decoding module.
