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.

Transmitting apparatus and control method therefor and receiving apparatus and control method therefor

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.

Communication device and communication method

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.

Communication apparatus, communication method, communication program and information recording medium having the program recorded thereon

A medium is set in a computer, and identification information of the set medium is read out. Related information about the medium is obtained in accordance with the identification information read from the medium. The obtained related information is displayed on a display.

Computer for a reproducing medium

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.

Data transmission/ reception system, connection restoring method and information transmission/ reception apparatus

System for processing information which reads address information

Data transmission/reception system, connection establishing method and information transmission/reception apparatus

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. Then, an outputting device forms transmission information including a plurality of the information units including at least any one out of among the audio information, the corresponding information, and one portion of the reproducing control information and outputs the transmission information to the bus.

Audio information reproducing system, audio information reproducing apparatus and audio information reproducing method

A reception interface unit in a transmission system wherein time series data is divided into data groups and a data packet with reproduction specification time data specifying a time at which each data piece in the data groups should be reproduced, added to the data groups is transmitted on a transmission bus in a time division manner. The interface unit has a cycle timer for counting the reference time of the home device based on the reference time on the transmission bus, a unit for extracting the reproduction specification time data in the data groups from a signal received via the transmission bus and storing the reproduction specification time data in a buffer, a reception buffer for inputting and storing the data pieces in the data groups in order and reading out the data pieces in the storage order responsive to a reproduction clock, a match detector for generating a reference clock pulse if the reference time of the home device matches the reproduction specification time, and a PLL circuit being responsive to the reference clock pulse for generating a clock signal which is phase synchronized with the reference clock pulse as the reproduction clock. When the reference time on the transmission bus changes, the data stored in the buffer in the reproduction specification time data extraction unit and the data stored in the reception buffer are all deleted.

Reception interface unit in transmission system

A receiving apparatus constructed to store data received from a network in a buffer and read the data in the buffer based on a reference clock, has a detecting means for detecting change of a sampling frequency of the data, a first controlling means for controlling to stop writing of the data into the buffer and reading of the data from the buffer in response to an output of the detecting means, a clearing means for clearing the data in the buffer in response to the output of the detecting means, a clock changing means for changing a frequency of the reference clock in response to the output of the detecting means, and a second controlling means for controlling to restart the writing of the data into the buffer and the reading of the data from the buffer in response to the output of the detecting means.

Receiving apparatus and flow control method therefor and transmitting apparatus and flow control method therefor

A transmission managing apparatus included in an information transmitting system comprising a communication bus (B), an indicating device (NI), which has a transmission state memory () for storing a channel used for an information transmission executed in a time division manner on the communication bus and a transmission occupation period occupied for the information transmission, for indicating the channel and the transmission occupation period and an information processing apparatus (N) for reserving a non-used channel and a preservable period, while referring to a memory content of the transmission state memory.
