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: In a video-audio synchronizing method for synchronizing video and audio reproduced respectively by a monitor 300 and an amplifier 400 connected to a serial bus 100 to which video from a DVD player 200 and audio associated with the video are supplied, the monitor 300 sends out delay time information caused by an intrinsic delay element for video display to the amplifier 400 through the serial bus 100 as a control command, and the amplifier 400 delays the audio by time necessary for synchronization between the video and the audio according to the control command and outputs the audio.

Abstract: 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.

Abstract: To provide a packet transmitter and a method for executing packet transmission fluently when a node having destination converging exists, a packet transmitter includes a destination storing unit for storing a packet to be transmitted separately in respective destination in sequence; a transmitting unit for transmitting the packet, which is stored separately in respective destination, separately in a destination sequence; and a control unit for stopping packet transmission for a predetermined period of time to the destination to which the packet transmission by the transmitting unit is failed.

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.

Abstract: A data transmission system capable of ensuring proper operation even when any nodes-to-bus connection, which is not allowed by restrictions, is made. The system implements data transmission among a plurality of nodes mutually connected by a cable serving as a bus. The system includes a first process for initializing a control process on the nodes to the bus in accordance with a change in an electrical connection of the bus, a second process of detecting a connection topology of the nodes, and a third process for identifying each node to be connected to the bus. A forbidden connection detecting process is provided for detecting if there is a loop connection path of the nodes on the bus and handling operations are provided for executing handling in accordance with a result of detection by the forbidden connection detecting process.

Abstract: An OFDM (Orthogonal Frequency Division Multiplex) broadcast wave receiver for receiving an OFDM broadcast wave, automatically discriminating whether the received signal is of a wide band or a narrow band by determining if a carrier signal having a predetermined frequency is present among signals of a plurality of frequencies, acquired by OFDM demodulation of the reception signal by demodulation means, and controlling the demodulating operation of the demodulation means in accordance with the discrimination result to thereby acquire a demodulated signal.
