摘要： Provided are a fast channel change apparatus based on multiple multicasts communication in an IPTV network, and a method thereof. In the fast channel change system, after separately generating at least one multicast stream obtained by applying different time delays respectively to original multicast stream to be broadcast, a channel server dynamically analyzes information regarding the at least one multicast stream. After querying the channel server for information regarding an optimal multicast stream and receiving the response to the query, a user terminal joins a multicast group on the optimal multicast stream through a router. After a predetermined time is elapsed, the user terminal joins a multicast group of the original multicast stream. Thus, it is possible to easily and inexpensively embody a fast channel change function network based on multiple multicasts communication in an IPTV network.

摘要： A transimpedance amplifier for a burst mode optical communication converts a burst current signal into differential output voltage signals. Using a multi-level digital AGC mechanism, the transimpedance amplifier is rapidly adapted to a burst signal whose amplitude varies in a wide range. By using an adaptive level detection method, a multi-level digital AGC can be implemented without using ADC. In addition, because the transimpedance amplifier uses a selective reset generation scheme that performs a reset operation for itself after a high power burst, a burst mode operation can be performed without external reset signals. Accordingly, the transimpedance amplifier can be integrated with an optical detector within a TO-can. Furthermore, the transimpedance amplifier can have the burst mode capability and the best sensitivity.

摘要： The invention relates to an EPON bridge apparatus and a forwarding method thereof. In a case of receiving a frame from the network port or the PON port, the apparatus associates the port having the received frame inputted with a source MAC address of the received frame to learn the information in an FDB table, which manages port information for the learned MAC address. Then the apparatus refers to the FDB table to remove an LLID from upstream frame, and then forwards the upstream frame to the network port, while attaching an LLID corresponding to a destination MAC address to the downstream frame to transmit to the PON port. Bridging between ONUs is possible with flooding capability using an anti-LLID. VLAN-LLID translation mode is provided with support for VLAN tag addition/removal at the ONU side. A multicast pruning function is provided for the downstream.
