A control unit is coupled to the first and second communication device. The first communication device is capable of detecting whether or not another apparatus is disconnected from the first communication device. The control unit is capable of setting the second communication device in an active state if the first communication device detects that another apparatus is disconnected from the first communication device when the second communication device is in an inactive state. The second communication device is capable of being used to communicate with another apparatus when the second communication device is set in an active state, and is not capable of being used to communicate with another apparatus when the second communication device is set in an inactive state.

Abstract: An image capture apparatus (for example, a camcorder) includes a first recording unit adapted to record a moving image on a first recording medium; a second recording unit adapted to record, on a second recording medium, related information including information required for searching for the moving image; and a controlling unit adapted to control the image capture apparatus to transmit the related information reproduced from the second recording medium to a controller connected to the image capture apparatus and control the image capture apparatus to search for the moving image in accordance with a command transmitted from the controller.

Abstract: A communication system, in which data transmission is interrupted for a bus reset, includes a source and a destination with a receiving buffer. The source is adapted to transmit a segment of data to the destination using address information corresponding to a part of the receiving buffer of the destination. Transmission of the data is interrupted if a process of resetting a bus between the source and the destination occurs. After the process of resetting the bus ends, the transmission of the data resumes without retransmitting data determined by the source to be already stored in the receiving buffer.

Abstract: A method and apparatus for remotely controlling adjusting functions of an image capturing apparatus. The functions include contrast, gamma, sharpness, aperture, and contrast. A control apparatus transmits to the image capture apparatus a first command requesting a current function value of an adjusting function of the image capture apparatus and a second command requesting a remotely controllable range of the adjusting function. The control apparatus detects the current function value of the adjusting function from a response to the first command and a remotely controllable range of the adjusting function from a response to the second command. The control apparatus then displays the current function value and the remotely controllable range of the adjusting function on a display unit of the control apparatus.

Abstract: Provided is a communication system for logically connecting a source node and one or more destination nodes, and for controlling data communication between the individual nodes by employing a connection ID that is used to identity the logical connection relationship. The communication system may comprise a source node adapted to transmit data packets, a destination node adapted to receive the data packets transmitted from the source node, and a controller adapted to manage a logical connection between the source node and the destination node, the destination node being adapted to abort communication between the source node and the destination node if the destination node received an abort packet transmitted from the controller, and the destination node being adapted to disconnect the logical connection after the communication is aborted by the abort packet. The source node itself, and methods of using the system and that node, are also individual aspects of what is disclosed.

Abstract: There is disclosed a communication system and communication protocol in which a source node and one or more destination nodes are logically connected, and a connection ID for identifying the logical connection relationship is used to control data communication between the nodes. There is also disclosed an efficient communication system and communication protocol in which an optimum time interval between a time to transmit an i-th (i being an optional integer) data and a time to transmit an (i+1)-th data can be set. There is further disclosed a communication system and communication protocol in which when the i-th data is not normally received, retry is inhibited only for a predetermined time to prevent the retry from unnecessarily occurring between a destination node slow in receiving process and a source node fast in transmitting process.

Abstract: The source transmits a packet with a predetermined transfer rate to each destination and recognizes the maximum transfer rate to each destination according to the presence or absence of response to such packet. After the maximum transfer rate is recognized, the source generates plural packets from the information data and transfers these packets in succession at the maximum transfer rate. Thus the maximum transfer rate available between two or more electronic devices can be easily detected without complicated analysis.

Abstract: Apparatus and method for cross-fading moving image signals include structure and steps for temporarily storing moving image signals in a memory for a predetermined period of time. Moving image signals read out from the memory and newly-input moving image signals are continuously combined for an operation time equal to or greater than the predetermined period of time. Thus, it is possible to obtain combined signals such that the moving image signals overlap each other in a relatively simple arrangement without using a special magnetic head.
