  • Publication number: 20050068914
    Abstract: Disclosed is a broadcasting and communication combining system based on an Ethernet and a method thereof for providing an Internet service and a multi-channel broadcasting service. The broadcasting and communication combining system and method based on an Ethernet uses Ethernet broadcasting frames on a data communication network to provide a wideband Internet service and a multi-channel digital broadcasting service. To support both Internet and broadcasting with one wavelength, the broadcasting traffic is converted to Ethernet data and multiplexed, and the multiplexed broadcasting traffic comprising the same band (one wavelength) of Internet data is transferred to a subscriber network. The subscriber terminal unit discriminates between Internet traffic and broadcasting traffic and outputs the Internet traffic and the broadcasting traffic to the final receiver.

  • Publication number: 20050030961
    Abstract: A ring selection method for a dual ring network to perform node-to-node packet transmission. A transmission node transmits a reception node address request message for packet transmission to all nodes, and updates a routing table using information on a short path transferred from the reception node. The information on inter-node hop numbers included in the routing table is used to select a ring having the lowest hop number between the reception nodes It is then determined whether the selected ring is wrapped, and if the ring is not wrapped, comparing its usage rate and hop number to the reception node with reference values based on a ring selection algorithm; and if the ring is suitable based on the reference values, selecting the ring for packet transmission.

  • Publication number: 20040133920
    Abstract: Provided is a digital broadcast system that receives digital broadcast services on a passive optical network (PON). The data separator separates a signal input thereinto from the outside into an Ethernet frame for data service and an Ethernet frame for digital broadcast service. The Ethernet switch transmits the Ethernet frame for data service to an optical network terminal (ONT) provided in the user's home according to header information of the Ethernet frame for data service. The channel request processor receives the user's channel selection request information and user identification (ID) information from the ONT. The digital broadcast processor transmits the Ethernet frame for digital broadcast service, corresponding to the digital broadcast channel selected by the user, to the user's ONT, by using a part of bandwidth assigned for an existing line.

  • Patent number: 6252444
    Abstract: A reset signal generation circuit of the present invention includes a phase locked loop (PLL) selector, a plurality of PLLs, a locking detector, a clock selector, a counter, and a reset synchronizer. The PLL selector is activated when an external reset signal is high and provides a signal for selecting one of the plurality of PLLs according to a power down control signal and a PLL selection signal. The plurality of PLLs have different input frequency signals and different output frequency signals. They are activated in response to an external clock signal and inactivated in response to the power down control signal. The locking detector detects locking/unlocking of the PLLs based upon the output frequency signals of the PLLs and generates a locking signal. The clock selector selectively provides one of the output signals of the PLLs and the external clock signal. The counter is coupled to the clock selector and generates an overflow signal after completing count of a predetermined number.
