Patent ID: 8452183

Claim:
A multimedia data transmitter, comprising: a digital signal processing logic, converting multimedia data transmitted in different transmission formats into data of a single transmission format, converting parallel image data into serial image data; an interface control logic, generating a control signal for transmission of the data converted by the digital signal processing logic, interfacing interface data; and an optical driver, performing optical transmission of the serial data generated by the digital signal processing logic according to the control signal generated by the interface control logic, processing an optical-to-electrical converted signal; and wherein the optical driver comprises: an optical drive logic, converting a digital serial data into an analog signal, performing optical transmission through driving an optical module; and an optical signal receiving logic to process a received signal that is optical-to-electrical converted by the optical module; and wherein the optical signal receiving logic comprises: a preamplifier pre-amplifying the received signal that is optical-to-electrical converted by the optical module; and a current-limit amplifier limiting a current level of the received signal pre-amplified by the preamplifier.
