    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. The Ethernet passive optical network has an optical line terminal, which is a central base station, and a plurality of optical network units. The method includes the steps of forming a synchronous frame using the OLT to transmit synchronous data for the ONUs, forming an asynchronous frame using the OLT to transmit asynchronous data for the ONUs, forming a super frame including the synchronous and asynchronous frames using the OLT, and transmitting the super frame using the OLT.

    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 method and apparatus by which a reception device of a communication system can sense and compensate for an error of a program clock reference (PCR), and can sense and compensate for bit rate variation of transmission data in a transmitted MPEG-2 TS. 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.

    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 system having a transmitter and a receiver provides sign language video data in a broadcasting-communication convergence system. A transmitter extracts data, to which a sign language is to be applied, from the multimedia data, converts the extracted data into motion data, converts the motion data into an avatar motion schema indicative of avatar motion data, converts the avatar motion schema into metadata, multiplexes the multimedia data and the metadata, and transmits the multiplexed data. A receiver receives the multiplexed data, demultiplexes the received multiplexed data, extracts an avatar motion schema using the metadata, generates sign language video data by controlling a motion of an avatar through the avatar motion schema, multiplexes the sign language video data and the multimedia data, and transmits the multiplexed data to a display unit.
