    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: Transmitting data in a synchronous Ethernet passive optical network employs a synchronous Ethernet for ensuring QoS during transmission of multi-media data, thereby specifying transmission of synchronous data and asynchronous data, respectively.

    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.

The method and apparatus compensates for a PCR jitter, or a change in a data bit rate, which may occur in processing an MPEG-2 TS in a reception device of the MPEG-2 TS transmission system, thereby preventing the deterioration of image quality due to the jitter or loss of an input MPEG-2 TS data. The apparatus includes a PAT sensing unit for sensing a PAT from a received MPEG-2 TS, a PMT sensing unit for sensing a PMT based on information provided from the PAT sensing unit, a PCR PID unit for sensing a PCR PID based on information provided from the PMT sensing unit and a PCR data unit for outputting a PCR data based on information provided from the PMT sensing unit and PID information provided from the PCR PID unit. The apparatus also includes a PCR comparison/compensation unit receiving the PCR data from the PCR data unit, comparing the received PCR data with a pre-stored PCR data, and compensating for the pre-stored PCR data, and a data rate comparison/compensation unit for receiving data rate information from the PCR data unit, comparing the received data rate with a pre-stored data rate, and compensating for the pre-stored data rate.
