摘要:
An address management method and a video apparatus using the same are provided. The address management method includes determining whether an external device is connected or not; when determining the connection to the external device, generating an invalidation message for invalidating an address; and transmitting the generated invalidation message to the external device. Accordingly, when the port connection is changed, the physical address can be correctly updated by invalidating the former physical address.
摘要:
A method for providing coordinate information to an external device and a video apparatus thereof. The coordinate information providing method includes receiving coordinate information input by a user from an input device; and transmitting a coordinate information delivery message containing the coordinate information input through the input device, to an external device connected according to a High Definition Multimedia Interface (HDMI) Consumer Electronics Control (CEC) specification. Accordingly, the video apparatus can control the external device by transferring the coordinate information to the external device.

A UWB receiver having at least one communication module with a limited working band whose on/off state can be controlled. The UWB receiver is adapted to detect power intensity of a received radio signal in the limited working band based on an on/off state of said at least one communication module. The UWB receiver is adapted to control the on/off state of the at least one communication module based on a result of the detection.
摘要:
A method for managing an address and a video apparatus using the same are provided. The method for managing an address includes acquiring an address of the apparatus, and determining whether or not the acquired address and an address of one of the external apparatuses collide if a command for resetting an address is received from another one of external apparatuses. As a result, collision of addresses between apparatuses may be prevented.
摘要:
A method of transmitting data more effectively, and more particularly, a method of classifying service traffic, transmitting data according to the classifications of the service traffic, and performing a contention free slot (CFS) allocation in order to transmit data in a power line communication (PLC) network, and an apparatus to do the same. The data transmission method includes determining transmission priority of data according to service traffic characteristics, and transmitting data according to the determined transmission priority, thereby providing differentiated quality of service (QoS) according to service traffic characteristics.

A method of data communication between power line communication (PLC) stations belonging to different PLC cells includes transmitting a station ID of a PLC reception station to a PLC cell bridge (CB) of a first PLC cell to which a PLC transmission station belongs, receiving a group identification (GID) and an encryption key of a second PLC cell to which the PLC reception station belongs from the PLC CB of the first PLC cell, encrypting data to be transmitted using the encryption key of the second PLC cell, and transmitting the station ID of the PLC reception station, the GID of the second PLC cell, and the encrypted data, to the PLC CB of the first PLC cell, and an apparatus to perform the method.
摘要:
Provided is an apparatus and method of displaying power line communication channel information. The apparatus for displaying power line communication (PLC) channel information includes a channel information determining unit which performs PLC channel estimation and determines channel information including a bandwidth which is available for a user in a power line communication network; and a channel information displaying unit which displays the channel information to the user. Since channel information is determined through channel estimation and displayed to a user, it is possible to easily check whether a channel can be used before installing a power line communication (PLC) device. In an application, information on kinds of a service which can be selected by the user or expected quality of the service can be previously checked. Accordingly, the user can know whether the communication can be performed, without installing a communication device or executing a communication application which requires much time and effort. Accordingly, it is possible to reduce time and effort necessary for finding an adequate communication point.

摘要:
An apparatus and method of streaming content by adaptively selecting a peer-to-peer (P2P) method or a server-client method according to a network environment, and a computer readable medium having recorded thereon a program for executing the method are provided. The apparatus includes middleware which supports the P2P method, middleware which supports the server-client method, an adaptation manager which provides a list of content, determines one of at least one node and at least one server sharing content which is selected as a source device according to a content sharing method and their available bandwidths, and determines a content sharing method used by the source device as a streaming method, and an application unit which controls the selected content to be received from the source device by using middleware and a transfer layer corresponding to the determined streaming method, and the received content to be reproduced.
