摘要： Disclosed is a method for transmitting asynchronous data in a synchronous Ethernet having a sync frame section and an async frame section. The method includes the steps of: a) allocating a priority to motion picture data for transmission through the sync frame section; b) determining if a size of the data of all frames for transmission in one cycle exceeds the predetermined length; c) dropping motion picture data having a lower priority (e.g. which corresponds to the size of the data exceeding the predetermined length); and d) transmitting the data in one cycle unit when the size of the data to be transmitted does not exceed the predetermined length.

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.
