A packet generating method in a wireless High Definition Multimedia Interface (HDMI) environment includes generating a packet which includes either AV data or control data in a payload and a field indicative of a packet type in a header according to a HDMI environment; and transmitting the generated packet. Accordingly, the AV data and the control data can be transceived over the single channel in the HDMI.

A method and apparatus of requesting service between network devices in which the range of service between network devices can be flexibly managed, a network device capable of performing the method, and a storage medium thereof are provided. The network devices includes: a network device requesting a partner network device to send service information; and if service information of the partner network device is received, requesting a service to the partner network device based on the received service information.

Method of requesting services of network devices, network devices capable of performing the method, and storage medium for storing the method

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.

Address management method and video apparatus using the same

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.

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.

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.

Method and apparatus for communication between coordinator-based wireless networks connected through backbone network

A method for broadcasting a data packet in a wireless universal serial bus (USB) environment, a method for receiving the data packet being broadcasted, a wireless USB host, and a wireless USB device are provided. The method for broadcasting a data packet in a wireless USB environment includes generating a management packet containing broadcast Channel Time Allocation (CTA) information, transmitting the management packet to at least one USB device within a cluster of USB devices, and broadcasting a data packet during a time indicated by the broadcast CTA information.

Method for broadcasting data packet and receiving the data packet in wireless universal serial bus (USB) environment, wireless USB host, and wireless USB device

A method for communication between first and second coordinator-based wireless networks connected through a backbone network is provided. The method includes receiving a frame indicating data transmission containing information needed for remote channel time allocation (CTA) from a repeater connecting the second coordinator-based wireless network with the backbone network, sending a remote CTA frame in order for the repeater to request CTA from the coordinator within the second coordinator-based wireless network, and receiving a data frame originated from the first coordinator-based wireless network and then provided by the repeater during assigned channel time.

Method for communication in coordinator-based wireless network and method for communication between coordinator-based wireless networks connected through backbone network

A method and system for communication between wireless networks connected through a wired network in a coordinator-based wireless network environment are provided. According to the method for communication, a wired/wireless relay device that attempts to associate with an initial coordinator-based wireless network notifies a coordinator of information indicating that it acts as a relay device. The coordinator sends the information to wireless network devices within an appropriate coordinator-based wireless network, and each of the wireless network devices transmits data to be transmitted to a device within a different coordinator-based wireless network to the relay device. When the relay device sends the data to a relay device in a coordinator-based wireless network a destination wireless network device belongs to through a wired network, the relay device in the same coordinator-based wireless network as the destination wireless network device sends the data to the destination wireless network device.
