摘要:
A sink device transmits a video information message to the source device, the video information message including video format information identifiers for identifying video formats supported by the sink device, which are selected from among a plurality of video format information identifiers for identifying video formats each including a resolution of the video data and a type of the video data, and a three-dimensional transmission method for three-dimensional video data when the type of the video data is the three-dimensional video data including first and second video frame data.

A mobile communication apparatus includes a registration request part (47) requesting a correspondent node to make location registration, a BU list memory (45) keeping a list of the correspondent nodes which have made the location registration, a handover detection part (41) detecting the start of a handover, and a registration cancellation processing part (46) canceling the location registration of the correspondent nodes in the BU list, upon notification of start of handover by the handover detection part (41), thereby reducing loss of packets transmitted from the correspondent nodes during the handover, because the route optimization applied to the correspondent nodes registered in the BU list at the start of the handover is canceled by requesting the cancellation to the correspondent nodes.
摘要:
A sink device wirelessly transmits a device capability response message to a source device. The device capability response message includes a video information message including at least one video format identification code (VIC) for identifying a video format of video data, which the sink device can display, and a coded video information message including compressing parameters for compressing video data. The VIC includes a VIC for 4k2k video data having 3840 or 4096 effective horizontal pixels and 2160 effective vertical pixels.

In a wireless communication system including a source device and a sink device for wirelessly transmitting and receiving a CEC message specified in an HDMI standard, a CEC controller of the source device generates and outputs a CEC frame including the CEC message. A controller generates a wireless data packet including the CEC message in the generated CEC frame. A wireless transceiver circuit wirelessly transmits a wireless signal including the generated wireless data packet to the sink device, and receives a wireless signal including a wireless ACK packet and wirelessly transmitted from the sink device in response to the wireless data packet in the wirelessly-transmitted wireless signal.

The present invention has an object to provide a wireless communications adaptor device which can reduce the connection time to the destination when another sink device is selected as the destination. A control unit (203) included in the wireless communications adaptor device determines whether or not a device ID of an adapter device for a sink device (105 or 106) and EDID information corresponding to the device ID are registered in an EDID managing table (206). The device ID and the EDID information are obtained through authentication processing with the adapter device for the sink device (105 or 106). When the device ID is registered, the control unit (203) copies the EDID information corresponding to the device ID to the EDID table (205). When the device ID is not registered, the control unit (203) obtains the EDID information from the authenticated adapter device for the sink device (105 or 106), associates the EDID information with the device ID, and stores the EDID information and the device ID in the EDID managing table (206).
摘要:
A router, if judging that a routing function is impossible to execute, sends out a connection instruction message including the address of a terminal on a local network terminating the relaying flow, to another router to solicit switching. The router having received the connection instruction message starts a process for connecting with an external network while executing a process for link connection with a terminal, and then sends out a connection completion notice message when the connection with both the external network and the terminal is established. This process enables the router to switch a path rapidly.

When the routing function of router becomes disabled, a routing stop message is multicast to all terminals and another router in a LAN. If another router can provide the routing function, a routing start message is multicast to all terminals and the other router in the LAN. This method allows the terminals in the LAN to switch the default router at a predetermined timing according to both messages, thus minimizing the default router switching delay time and the packet loss.

When connected to an external network, a mobile router checks an address 0table if a home address is allocated. If it is not allocated, the mobile router derives the address of a position management server from a position-management-server address table and sends an allocation request message to the position management server. The position management server receives an address management table listing addresses to be allocated to each mobile network and the allocation request message sent from the mobile router, searches the address management table for an unused address, and sends an allocation permission message to the mobile router to automatically allocate a home address to the mobile router.
摘要:
A router device includes a lower-layer information acquisition section for acquiring connection information of whether or not connected with a base station in an external network from a lower layer, and a route judgment section for transferring the received packet to the base station in the case of being connected with the base station and judging a transfer destination by looking up a routing table in the case of not being connected with the base station, when receiving a packet destined for a terminal in an external network from a radio terminal device in a same local network. Because the received packet is transferred to the base station during connection with the base station, the packet can be transferred to the external via the router intended by the terminal. Furthermore, the load in the local network can be reduced.
