An address management method and a device thereof are provided. The address management method includes checking by a device whether logical addresses are currently being used by external devices; and setting by the device a non-use logical address as a logical address of the device regardless of the type of the device, if the device determines that the non-use logical address exists. Therefore, a device may use all logical addresses regardless of its device type, and may also have a logical address even though all logical addresses corresponding to its device type are currently being used.

Method for managing logical address and device thereof

An address management method and a device thereof are provided. The address management method includes determining by a device whether all logical addresses corresponding to a type of the device are currently being used by external devices; setting by the device a non-use logical address as a logical address of the device, if it is determined that one of the logical addresses is currently not in use; and setting by the device a predetermined logical address as a logical address of the device, if it is determined that all the logical addresses are currently being used. Therefore, logical addresses may be allocated to a device even if all logical addresses corresponding the type of the device are currently being used.

An apparatus and method for transmitting and receiving multimedia broadcasting in order to provide multimedia broadcasting services and interactive broadcasting services are provided. An apparatus for receiving multimedia broadcasting includes a reference clock receiver, which receives a reference clock value, i.e., a current time value, of real-time multimedia broadcasting; a multimedia document receiver/storage, which receives and stores a first multimedia document; a media data receiver/storage, which receives and stores first media data; and a multimedia document renderer, which when the first multimedia document is scheduled at the reference clock value and the first media data is a rendering material used to render the first multimedia document, renders the first multimedia document using the first media data.

An apparatus and method of transceiving a bit stream, by which a video bit stream is stably transmitted by the effective use of two logic channels when communication is established by the two logic channels during transmission of the video bit stream in a communication network, is provided. In this method, a source is encoded into a bit stream using a predetermined type of coding. Then, the encoded bit stream is transmitted to each communication protocol layer, while the header of each communication protocol layer is added to a payload. The header is transmitted separately from the bit stream.

Apparatus for transmitting/receiving a bit stream in a network and method therefor

A method and device for bi-directionally transmitting and receiving data during an allocated time period are provided. The device includes a Physical Layer (PHY) module receiving a Medium Access Control (MAC) frame through a wireless medium, a MAC module reading a value of a first field in the received MAC frame, wherein the first field specifies whether there is more data to be sent, and a transmission rights determining module determining that a transmission right has been passed to the wireless device when the value of the first field is a first bit and a channel is idle during a predetermined threshold time after reception of the MAC frame, wherein the first bit represents that there is no more data to be sent.

Method for transmitting and receiving data bi-directionally during allocated time and wireless device using the same

A method of retransmitting a data frame and a network apparatus using the method are provided. In the method performed in a wireless network, a first network apparatus transmits a data frame requesting a response frame. A second network apparatus determines a type of response frame according to a reception mode of the data frame. The second network apparatus transmits the determined type of response frame to the first network apparatus. The first network apparatus retransmits the data frame according to the type of the response frame transmitted to the first network apparatus.

Method of retransmitting data frame and network apparatus using the method

A method and apparatus are provided for communication among many coordinator-based wireless networks connected together through a wired backbone network using wired/wireless connecting devices. According to the method and apparatus, communication is allowed between wireless devices belonging to different coordinator-based wireless networks through wired/wireless connecting devices using physical addresses, whose uniqueness is ensured across the whole network, instead of using ID information assigned by a PNC, as physical addresses of a destination network device and a source belonging to different coordinator-based wireless networks.
