摘要： A broadcast/communication convergence system and method for transmitting and receiving Ethernet data by an optical network unit (ONU) performing a time division multiplexing (TDM) operation and switching by a network switch. A resultant signal is transmitted to a corresponding subscriber set-top box (SSTB), and data from the SSTB is provided to the network switch. A length of an Ethernet data frame is provided from the network switch, and an encapsulation generates and inserts data length information into an Ethernet data frame, for transmission to the SSTB. The SSTB carries out a TDM operation for a signal transmitted from the ONU, and separates the signal into Ethernet and broadcast data. A framing bit is detected based on a result of the separated signals, the length information is detected. A preamble bit and a start-of-field delimiter (SFD) are inserted into the recognized Ethernet data to recover the original Ethernet data.

摘要： A broadcast/communication convergence system and a method for transmitting and receiving Ethernet data using the same is disclosed. The system is equipped with an optical network unit performing a time division multiplexing operation on the Ethernet data switched by a network switch and a plurality of broadcast data units, transmitting a resultant signal of the operation to a corresponding subscriber set-top box, and providing data from the subscriber set-top box to the network switch. In one aspect of the invention, the optical network unit produces a length of an Ethernet data frame provided from the network switch. An encapsulation operation is carried out by generating data length information and inserting the generated length information into an Ethernet data frame. Encapsulated Ethernet data is transmitted to the subscriber set-top box. The subscriber set-top box carries out a time division demultiplexing operation for a signal transmitted from the optical network unit, and separates the signal into the Ethernet data and broadcast data. When a framing bit is detected from the frame of the Ethernet data based on a result of the separation, the length information is detected from the Ethernet data frame. The Ethernet data frame is counted on the basis of the detected length information and recognizing the Ethernet data. A preamble bit and a start-of-field delimiter (SFD) are inserted into the recognized Ethernet data and the original Ethernet data is recovered.

摘要： Disclosed is a method for establishing a synchronization in a synchronous Ethernet system. Devices are classified according to the type of the devices, and a device having a highest class in the synchronous Ethernet system is detected, then it is determined if the device having the highest class is able to serve as the timing master. If so, the device having the highest class is able to serve as the timing master if only one such device is detected; otherwise, the timing master between devices having the highest class is selected through a collision algorithm.
