Abstract: There are provided the controlling methods of the transmitting apparatus and the receiving apparatus, which cancel the flow control to execute the normal reproduction by the user who looks at the warning display or in response to the reception of the flow control cancel signal from the receiver side. Otherwise, there are provided the controlling methods of the transmitting apparatus and the receiving apparatus, which cancel the flow control reception to execute the normal reception without the buffer if the contents with the video is reproduced.

Abstract: A control unit controls setting of an operating mode. A timer determines a transmission period of a beacon for notifying presence of a network. A beacon transmitting unit transmits a beacon based on the transmission period. When the control unit instructs to switch from a normal operation mode to a power-saving operation mode, the timer sets a transmission period of the beacon to be longer than a transmission period in the normal operation mode.

Abstract: A communication apparatus is to be connected to a network to establish, one or more connection with one or more processing apparatus connected to the network, to perform at least one of transmission and reception of data. The communication apparatus includes a reception device, a judgment device and a protection device. The reception device receives a disconnection request for disconnection of the connection, from the processing apparatus. The judgment device judges whether the disconnection request as received is legal or not. The protection device causes, only when there was made a judgment that the disconnection request as received is not legal, disablement of execution of a disconnection processing in response to the disconnection request to protect the connection.

Abstract: A purpose of the present invention is given as follows: That is, QoS of isochronous data can be effectively secured, and asynchronous data can be transferred with a small delay. In an information communication apparatus 100 of the present invention, in which both isochronous data and asynchronous data which are received by an IEEE 1394 receiving unit 210 based upon IEEE 1394 are transmitted by an IEEE 802.11 transmitting unit 300 based upon IEEE 802.11, the information communication apparatus 100 is equipped with: a packetizing unit (1) 230 for converting the isochronous data into data in a packet format of IEEE 802.11; and another packetizing unit (2) 240 for converting the asynchronous data into data in a packet formed of IEEE 802.11 based upon the packet format of the isochronous data converted by the packetizing unit (1) 230.

Abstract: There are provided the controlling methods of the transmitting apparatus and the receiving apparatus, which cancel the flow control to execute the normal reproduction by the user who looks at the warning display or in response to the reception of the flow control cancel signal from the receiver side. Otherwise, there are provided the controlling methods of the transmitting apparatus and the receiving apparatus, which cancel the flow control reception to execute the normal reception without the buffer if the contents with the video is reproduced.

Abstract: A communication apparatus according to the present invention serves as a manager apparatus which manages a communication network, and includes a database 13 that stores a device list of a terminal constituting the communication network; a network management unit 11 that checks the presence of a terminal registered in the device list by a polling processing, and updates the device list based on a result of the check; and a packet analyzer 12 that analyzes whether or not a received signal is a response to a presence check message sent in the polling processing, for example. In the communication apparatus, when a new request for updating the device list occurs during performing an active processing for the device list update, the network management unit 11 identifies a result of the active update processing as a result of processing the new request, without performing a new processing for the device list update in response to the new request.

Abstract: At each node of the data transmission/reception system of the present invention on a bus of an IEEE 1394, the following operations are sequentially performed: necessary initialization at the time of bus resetting; and GUID acquisition, restoration of Broadcast-out connection, restoration of Broadcast-in connection, and restoration of Point-to-point connection according to a restoration connection queue registering an execution order of respective connection restoration operations if there is a PENDING status of each connection before a passage of a predetermined time, after the bus resetting. Moreover, the restoration of each connection is subdivided into a plurality of processing steps when necessary, and controlled to select a proper processing step.

Abstract: An audio information reproducing apparatus for reproducing audio information on a recording medium, which can be connected with a bus. In the medium reproducing control information for controlling a reproducing mode of the audio information and the audio information are recorded. The reproducing control information has an amount of information larger than that capable of being inserted into one information unit formed during transmission via the bus. In the apparatus a detecting device detects the audio information and the reproducing control information from the medium. Then, a generating device generates corresponding information indicating a corresponding relationship between the audio information and the reproducing control information.
