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.

摘要： A method of enabling transmission of a time-critical control signal event in a sync frame period, such as a pause signal that is generated when the receive buffer of an Ethernet switch is filled with packets beyond a threshold due to congestion of uplink asynchronous data, is disclosed. To transmit time-critical information in a synchronous Ethernet system, a current transmission period is checked upon detection of a time-critical event. If the current transmission period is a sync frame period, time-critical control information is generated, inserted into the first sub-sync frame after the time-critical event, and transmitted. If the current transmission period is an async frame period, a control frame including the time-critical control information is generated and transmitted.

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： 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.

摘要： An apparatus and a method for adjusting a transmission rate of data, in particular a moving picture experts group 2 (MPEG-2) data. The apparatus includes a receiving buffer for buffering multi program transport stream (MPTS) packets received at various transmission rates, and a packet storage for storing MPEG-2 null packets. A signal processing section reads data buffered in the receiving buffer at a predetermined output transmission rate, wherein the signal processing section stops an operation of reading data buffered in the receiving buffer, and reads and transmits the MPEG-2 null packets stored in the packet storage when a predetermined underflow occurrence forecast situation is caused in the receiving buffer. In addition, the method for adjusting a transmission rate of MPEG-2 data includes: reading and transmitting buffered data when a current buffered data point (CF) reaches a predetermined data output point (HF) in a receiving buffer which receives the input MPST packets, stopping the reading of data buffered in the receiving buffer and transmitting MPEG-2 null packets when the current buffered data point ( CF) reaches a predetermined underflow forecast point (QF) in the process of reading the buffered data; and reading and transmitting buffered data when the current buffered data point (CF) reaches the data output point (HF) in the process of transmitting the null packets.
