An IRD 103 supplies broadcasting data on a bus in a desired time period. When the IRD 103 performs a reservation of the bus usage, the IRD 103 requests current bus usage information and information of the bus reservation from all devices connected by the bus, such as a DVD 104, a D-VTR 101, a D-VTR 102, a CAM 105, a TV 100, and a isochronous manager 107 of the D-VTR 101. The isochronous manager 107 and each device answer by sending the bus usage information and reservation information to the IRD 103. The IRD 103 judges a possibility of the reservation from the answer information. If the reservation is possible, it performs the reservation operation. If the reservation is impossible, then the reason is displayed on a TV 100. Therefore, it is possible to prevent a usage of a device that excesses the bus transferring capacity.

摘要:
A device including a self-information memory which stores function data for other devices to operate the device and device name data. Upon receiving a request from another device for the device name or function data, the device sends the data stored in the self-information memory. When function data is thereafter received, the device executes a function indicated by the data. When plural devices are connected to each other via a network, device acting as a mater device, includes a connected device memory which stores device name data of all connected device and a communication pair memory which stores function data of the communication partner.
摘要:
In a data recording apparatus capable of recording data while varying the amount of data per unit of time (at a variable rate), the present invention makes it possible to indicate an allowable recording time period on a disc and operational information according to user-specified setup conditions and the remaining capacity of the disc when a user determines conditions for record programming. An allowable recording time period on the disc is calculated on the basis of the remaining capacity of the disc and at least one of the following parameters; a maximum variable-rate value, a minimum variable-rate value, and an average variable-rate value to enable recording video data in most cases. Then, the result of calculation is displayed on a screen. Further, according to user-specified setup conditions including a programmed recording time period and the calculated allowable recording period on the disc, it is determined whether a normal variable-rate recording operation is applicable or an adjusted variable-rate recording operation is required. The result of the determination is displayed on a screen which is so arranged that the user can select either the normal variable-rate recording operation or the adjusted variable-rate recording operation.
摘要:
A device includes self-information memory which stores both function data for other devices to operate the device and device name data. Upon request from another device, the device sends the requested data stored in the self-information memory. When function data is received, the devices executes an instruction indicated by the data. When a plurality of devices each including the self-information memory are connected to each other via a bus or the like in a form of a network, at least one of the devices, includes, in addition to the self-information memory, a connected device memory to store therein device name data of all of the connected devices and a communication pair memory to store therein function data of the communication partner. The master device requests the other devices for device name data thereof, and stores the received data in the connected device memory. Thus, by referring to the device name data stored in the memory, the control device recognize the device name of the connected device. Also, the master device requests the other devices for function data thereof, and stores the received data in the communication pair memory. Therefore, by referring to the data stored in the pair memory, the master device recognize the function of the communication partner. Thus, when a function is selected and function data related thereto is sent to a communication partner, the function can be accordingly executed.

A device includes a self-information memory to store therein function data for other devices to operate the pertinent device and device name data thereof. Receiving a request from another device for the device name or function data, the device sends the data stored in the self-information memory. When function data is thereafter received, the device executes an instruction indicated by the data. In case where a plurality of devices each including the self-information memory are connected to each other via a bus or the like in a form of a network, at least one of the devices, i.e., a master device includes in addition to the self-information memory a connected device memory to store therein device name data of all of the connected devices and a communication pair memory to store therein function data of the communication partner. The master device requests the other devices for device name data thereof. When the requested data is received, the master device stores the data in the connected device memory. Consequently, by referring to the device name data stored in the memory, the control device recognize the device name of the connected device. Moreover, the master device requests the other devices for function data thereof. When the requested data is received, the master device stores the data in the communication pair memory. Therefore, by referring to the data stored in the pair memory, the master device recognize the function of the communication partner. In consequence, when a function is selected and function data related thereto is sent to a communication partner, the function can be accordingly executed.
摘要:
A recording medium having a data management structure capable of efficiently determining whether or not an outline image representing the outline of an original image and character information representing additional contents are added, and an motion-picture voice recording/reproducing apparatus for improving a retrieving operation factor of the recorded original image by generating and outputting the outline image from the original image even when the outline image is not added. Recording position information of images representing an outline of motion-picture and a voice signal, recording position information of character information representing additional contents relating to the motion-picture and voice signals, and/or information representing that the images representing the outline or the character information is not set by a user or by a system, are recorded to, and reproduced from, the recording medium.
摘要:
An electronic device connected to a network corresponding to plug & play and hot plug functions and enabled to control other electronic devices is provided with communication route detecting unit for detecting a communication route between electronic devices being used or reserved for communication and notifying unit for notifying the user of a result of detection by the communication route detecting unit. The above-described electronic device is configured so as to detect a communication route between subject electronic devices to be used for communication and notify the user of the electronic devices on the communication route, which must not be disconnected from the network with use of the communication unit. Consequently, the user can be prevented from accidental disconnection of the cable of a subject electronic device, thereby preventing the disconnection of the device from the network.
