FTTH system for broadcast/communication convergence using IEEE 1394

Abstract

A broadcast / communication convergence system, and an FTTH (Fiber To The Home) system that can accommodate broadcast signals of various channels and variable band signals by converging broadcast and communication signals and transmitting the converged broadcast and communication signals using an IEEE 1394 transmission method serving as a standard interface in the FTTH system for broadcast / communication convergence. An OLT (Optical Line Terminal) transfers a plurality of broadcast signals and a communication signal received from external broadcast and communication providers through a single optical signal (A). An ONU (Optical Network Unit) receives the optical signal (A) from the OLT, separates the received optical signal into the plurality of broadcast signals and the communication signal, opto-electrically converts the plurality of broadcast signals and the communication signal, switches the converted broadcast signals subscriber by subscriber, combines the converted communication signal with the switched converted broadcast signals. The result is transferred to a corresponding subscriber through a single optical signal (B). A gateway at each subscriber is implemented by IEEE 1394 protocol to receive the optical signal (B) from the ONU, separate the received optical signal into the broadcast signals and the communication signal, and transfer the broadcast signals and the communication signal to a corresponding subscriber device.

Description

technical field [0001] The present invention relates to a broadcast / communication convergence system. More specifically, the present invention relates to broadcasting in FTTH (Fibre to the Home) systems. Background technique [0002] Current communication / broadcasting subscribers have the option of using data services, choose from a number of data services via ADSL (Asymmetric Digital Subscriber Line), VDSL (Very High Bit Rate Digital Subscriber Line), Ethernet LAN (Local Area Network), cable modem, etc. eg Said data services such as very high speed Internet services, broadcast services from at least one cable and satellite broadcast based on HFC (Hybrid Fiber Coaxial) systems can also be used. In other words, subscribers can choose to use different media to receive communication and broadcast services. In the case where there is a combination of protocols, the communication service rate is only a few Mbps. [0003] In order to provide subscribers with high-speed, large-c...

AI Technical Summary

Problems solved by technology

For this reason, conventional FTTH systems for broadcast / communication convergence cannot accommodate broadcast signals based on different standards (such as broadcast signals of different wavelengths), and cannot accommodate three-channel broadcast signals
