Abstract: In a system in which an IEEE 1394 interface is provided for an IRD, connected equipment can be easily selected and the operability is improved. Data can be transmitted among the equipment by providing the IEEE 1394 interface for the IRD. For example, five equipment units are selected from the equipment connected to the IEEE 1394 interface and node ID numbers are allocated to the five equipment units and registered. Thus, even if the equipment is removed from the interface and connected again, the IRD can recognize the equipment. The registration may easily be changed by user input. When the registration is changed, the change of the registration is inhibited among equipment units in which a program reservation has been set or the connected equipment. Thus, even if the registration is changed, an erroneous operation does not occur.

Abstract: When an analog-recorded tape cassette is loaded into an apparatus which can perform an analog recording/reproduction and a digital recording/reproduction by a same video tape and is reproduced, an alarm is displayed. When a tape cassette in which a transport stream of different specifications or a digital video signal of a system other than the MPEG2 system has been recorded is loaded into the apparatus and reproduced, an alarm is displayed. The user watches a smart file picture plane and recognizes recording system information of a program to be monitored from now on. If the program to be reproduced has been digitally recorded, the user switches the input to a digital video input. If the program to be reproduced has been analog-recorded, the user switches the input to an analog video input.

Abstract: A receiving system and a receiving device are provided for receiving and processing broadcast digital and analog signals such as video and audio programs. The system and device are capable of determining whether a received program is subject to copy prohibition. If the program is subject to copy prohibition, the system prevents copying of the program. The system and device are capable of performing timed recording of received programs, including checking the status of the device and/or the recording medium to determine whether timed recording is permitted. Timed recording may be permitted if a selected broadcast receiving device is a registered device.

Abstract: To lessen the burden of a controller having an IEEE 1394 method or the like in a network requiring the controller. A transmitting system for transmitting data from a transmitting device (51) connected to a predetermined network to a receiving device (52) connected to the network, comprises a first device 53 having a control section for requesting connection management on the network for a data transmission to another device when an instruction for the data transmission is received from the transmitting device (51) or the receiving device (52), and a second device (60) having a control section for executing the connection management for the data transmission based on the request sent from the first device (53).

Abstract: Software-creating portion 11 creates update data and version-up data and supplies them to a receiver 20 through a delivery portion 13 or a server 15. The update data includes pieces of revision information of the version-up data after a period of time of each of their applications. Revision-information-processing portion 31 supplies revision information relative to software in a memory 34 to rewriting portion 33 and maintains remaining revision information. Data-revising portion 32 extracts revision information relative to the version-up data that is supplied through interfaces 25 and 26 from revision information maintained in the revision-information-processing portion 31, revises it to the latest one with it reflecting the version-up data, and then supplies it to the rewriting portion 33. The rewriting portion 33 rewrites the software in the memory 34 with the revision information and the version-up data thus supplied.

Abstract: When data is transmitted by using a broadcasting channel of an IEEE1394 interface, it is enabled to cope with a case where undefined equipment is connected to an IEEE1394 bus. The IEEE1394 interface is provided for an IRD, thereby enabling the IRD and equipment such as digital VCR, MD player/recorder, or the like to be connected. A node No. “63” of IEEE1394 is set to the broadcasting channel. Data is transmitted to all equipment connected to the IEEE1394 bus by the broadcasting channel. In the broadcasting channel, a picture plane for selecting a transport stream of MPEG and PCM audio data is displayed, and the data which is transmitted by the broadcasting channel can be selected in accordance with the transport stream of MPEG and the PCM audio data. Thus, when undefined equipment is connected to the IEEE1394 bus, it is possible to cope with any equipment.

Abstract: An information receiving apparatus instructs a storage device to be ready to perform a downloading operation. For example, the information receiving apparatus instructs the storage device to perform a setup for a recording wait status when the information receiving apparatus has the storage device start the downloading mode, and instructs to start and stop recording on a recording device by detecting the start and stop timing of recording data which a data transmitting section transmits. The information receiving apparatus also requests the storage device to report an operation condition at the storage device during the downloading mode. The information receiving apparatus determines a downloading-operation condition according to the operation-condition report sent from the storage device and appropriately controls the downloading operation.

Abstract: The using circumstances of a control object device are detected, and controlling of the control object device is carried out on the basis of the detected result. Thereby, where control equipment in conformity to a fixed standard, control equipment not in conformity to a fixed standard, and a control object device are mixed in a network, there can be avoided inconvenience in which the respective control equipment control the control object devices simultaneously.

Abstract: The precision of an initial image is reduced through image automatic processing in a manner simulating techniques used in the production of a custom art work. The resulting image, although generated without human intervention, has a pleasing, customized appearance which can be desirable to consumers seeking decorative art work. One way of reducing the precision of the initial image is modifying portions of the image to have more uniform luminance, color saturation, or color hue, producing a resulting image appearing to contain brush strokes. Alternatively, the precision of the initial image is reduced by locating contrast edges in the image, and modifying the luminance along these edges, producing a resulting image in which objects and features are outlined and have an enhanced definition from the background.

Abstract: A method and apparatus in which image data are pre-processed before undergoing block-basis image compression to compensate at least partially for the artifact known as the blocky effect that would otherwise be apparent upon decoding of the compressed data. The input data are pre-processed by combining error-correction data therewith, before block-basis compression is performed thereon. Blocky effect errors introduced during block-basis compression (e.g., standard MPEG compression) of the pre-processed input data and subsequent decoding will cancel (at least partially) the error-correction data, thereby compensating (at least partially) for the blocky effect that would otherwise occur without pre-processing.

Abstract: In control using a patch correctable microcomputer, the patch correction can have no effect on the timing of the control operation of the micro computer. Call instructions CALL 1, CALL 2 . . . for shifting, in synchronism with the operation of the microcomputer, over to a patch correction program in a RAM, are intermittently inserted into a control program stored in a ROM. A reciprocal number of invalid instructions NOP are put after this patch correction program in accordance with the length of the patch correction program. After a patch correction program has been carried out, the program in the ROM is returned to after a passage of time set according to the number of invalid instructions, so that the time for execution of the program in the RAM which is based on the microcomputer call instruction can be made constant irrespective of the length of time of the patch correction program, and will therefore have no effect on the timing for carrying out the program in the ROM.

Abstract: A video camera which is able to reverse the direction of the moving focus lens if appropriate evaluation data is not obtained within a certain period of time after an intermediate point is detected during the focus lens movement in one direction. This eliminates the redundant operation of the focus lens moving away from the just-focus point all the way to the extreme of the current direction before heading back to the just-focus point during an auto focus operation. An efficient auto focus operation is thus achieved. In addition, control is provided for not using a decrease in accumulated data as auto focus control information if that decrease is judged to be an abrupt drop from the accumulated data obtained in the immediately preceding focus lens position. This makes it possible to prevent the focus lens from being erroneously focused in cases of panning and other focus-disrupting operations. In this manner, the photographing of high quality is always made available.
