摘要： A communication/broadcast multiplexer and demultiplexer for multiplexing and demultiplexing communication and broadcast signals using a specific transmission standard in an optical network system that integrates broadcast and communication services using a channel selection technique. The multiplexer comprises a broadcast data input unit, a communication data input unit, and a synchronous Ethernet framer. The broadcast data input unit receives broadcast data switched on a subscriber basis through a broadcast switch in an optical line terminal (OLT) in the system, and transfers it as a synchronous data frame to the synchronous Ethernet framer. The communication data input unit receives communication data on a subscriber basis through an Ethernet switch in the OLT and transfers it as an asynchronous data frame to the synchronous Ethernet framer. The synchronous Ethernet framer converts both the received synchronous and asynchronous data frames into a TDM synchronous Ethernet frame, and outputs the TDM synchronous Ethernet frame.

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： A Residential Ethernet switching apparatus for performing time slot switching includes an input unit for receiving frames as input, and a parser for parsing the received frames into asynchronous Ethernet frames (AsyncE frames) and Residential Ethernet frames (ResE frames). An AsyncE switching processor performs a switching operation for an AsyncE frame parsed by the parser. A ResE switching processor performs, according to positions of time slots included in a ResE frame parsed, a virtual MAC (VMAC) processing for the ResE frame The ResE switching processor also performs a switching operation based on a result of the VMAC processing. A multiplexer multiplexes the AsyncE frame switched by the AsyncE switching processor, and the ResE frame switched by the ResE switching processor, for output.
