    摘要: Provided are a channel time allocation method and apparatus adopting the same. The channel time allocation method includes: (a) receiving a request of registering in a network from a device; (b) determining whether the network supplying a service required by the device exists; and (c) if the network supplying the requested service exists, performing a procedure of registering in the network, and if the network supplying the requested service does not exist, generating a new network. Since existing MAC protocols can be used in the channel time allocation method, an optimum service is provided in a network environment in which different kinds of services coexist.

    摘要: A method, a media renderer device and a media source device for providing content over a network, and a message structure for controlling a real-time transport protocol (RTP) are provided. The method includes transferring a hypertext transfer protocol (HTTP) control command generated so that content is provided from a media server providing content using a RTP. The HTTP control command can use an HTTP POST command or an HTTP PUT command. When transferring AV content using a RTP, the content is controlled using an existing HTTP not a Real-Time Streaming Protocol (RTSP). Accordingly, a RTP can be more easily supported.

    摘要: A method and apparatus for Ultra Wideband (UWB) communication, wherein in a UWB transmission method, a codeword stream is generated by performing spread spectrum used in Direct Sequence Code Division Multiple Access (DS CDMA) on a bitstream, followed by performing Orthogonal Frequency Division Multiplexing (OFDM) modulation .on the codeword stream. In a UWB reception method, UWB signals are received and subjected to UWB demodulation to obtain OFDM signals. The obtained OFDM signals are subjected to OFDM demodulation to obtain a codeword stream. Then, spread spectrum used in the DS CDMA is performed on the codeword stream, thereby generating a bitstream. The method and apparatus provide UWB communication having characteristics of both of Multi-Band OFDM (ODM) and Direct Sequence Code Division Multiple Access (DS CDMA).

    摘要: A telephony service system employing a cable network and a telephony service method. The system includes a directory unit, a plurality of network segment units each including a headend unit, and a plurality of routers respectively formed in each network segment unit. The directory unit stores the IP address corresponding to a telephone number of a first cable phone. The plurality of network segment units each having a headend unit read IP addresses stored in the directory unit based on a received telephone number of a second cable phone, and determine a connection audio session using an Internet protocol from the read IP address to set a call path with the first cable phone. The plurality of routers set a call path between the network segment units. According to the cable network of a packet type, unlike a PSTN network of a switch network, the local call charge is reduced. A wide bandwidth of the cable suppresses deterioration in quality of audio service of the cable network, which may be caused by compression or delay in the PSTN network.
