Abstract:
The present invention discloses a home network system (1) using a living network control protocol. The home network system (1) includes: at least two electric devices (40 to 49) (e.g., a first and a second electric device); and a network based on a predetermined network for networking the electric devices, wherein the first electric device (40 to 49) sends a request message to the second electric device (40 to 49), and the second electric device (40 to 49) sends a response message to the first electric device (40 to 49), wherein the response message transmitted from a lower layer to an upper layer of the second electric device (40 to 49) is transmitted to a lower layer and then to an upper layer of the first electric device (40 to 49) and includes a command code included in the request message, for indicating an operation for the second electric device (40 to 49) to execute, and a field related to an execution of the request.
Abstract:
The present invention discloses a data processing method for application layer based on a living network control protocol. The data processing method for application layer which is based on a predetermined protocol composed of at least a lower layer and an application layer includes the steps of: receiving a predetermined primitive from an upper application software; generating a communication cycle identifier (CyclelD) according to the primitive; generating a service description according to the primitive and the communication cycle identifier (CycleID); composing an application layer protocol data unit (APDU) including the primitive; and transmitting the APDU to the lower layer.
Abstract:
The present invention discloses a home network system using a living network control protocol. The home network system includes: at least one new device including a node address having an initial logical address through a network based on a predetermined protocol, transmitting a configuration request message having the node address to a master device, receiving a temporary address setting request message, changing the initial logical address by selecting one temporary logical address, generating a temporary address setting response message, transmitting the temporary address setting response message to the master device, receiving an address change request message having a predetermined logical address from the master device, changing the temporary logical address into the received logical address, and having a unique node address; and at least one master device for receiving the plurality of configuration request messages (S11) from the new device, setting the temporary logical address range for the new device, transmitting the temporary address setting request message (S18) having the set temporary logical address range to the new device, receiving the temporary address setting response message (S20) from the new device, setting the predetermined logical address of the new device, and transmitting the address change request message (S22) having the set logical address to the new device of the selected temporary address.
Abstract:
The present invention discloses a home network system using a living network control protocol. The home network system includes: an electric device (40d) having at least two heterogeneous function means; a network based on a predetermined protocol; and a network manager for controlling and/or monitoring the electric device (40d) through the network, the electric device (40d) including a packet processing device (210a) having one node address provided by the network manager, generating a packet having the node address, transmitting the packet to the network manager, receiving the packet having the node address from the network manager, and enabling the heterogeneous function means corresponding to a command included in the packet to execute the command.
Abstract:
A receiver is disclosed. The receiver comprises: a first receiving unit for receiving non-real-time data for constituting multimedia content; a storage unit for storing the non-real time data; a second receiving unit for receiving real-time data for constituting multimedia content; a data processing unit which, if the real-time data has been received, detects the non-real time data, in conjunction with the real-time data, from among the data stored in the storage unit, binds the detected non-real-time data and the received real-time data, and outputs multimedia content; and a control unit for controlling the data processing unit so as to restrict the output of the non-real-time data prior to the time of the output of the real-time data. Accordingly, the non-real-time data can be prevented from being carelessly reproduced.
Abstract:
A gigabit passive optical network (GPON) system for fiber to the home (FTTH) service must provide a downstream data rate of an optical band to provide IPTV service with hundreds of channels to subscribers, and must be able to provide an upstream data rate of an optical band using a currently available BM-IC chip. A currently available BM-IC chip for a GPON has 1.244Gbps and 2.488Gbps modes. Accordingly, an optical network terminal (ONT) for a GPON that is capable of providing a downstream transmission band of 10-Gbps and an upstream transmission band of 1.244Gbps or 2.488Gbps, and a method for processing an upstream frame in the terminal, are provided. The GPON ONT can provide 20Mbps, high-definition IPTV service with 500 channels and can provide both upstream data rates of 1.244Gbps and 2.488Gbps according to a user's selection without using an additional device.
