Abstract:
The disclosed system comprises an information carrier (1) on which an information signal is recorded that represents picture information intended for being displayed on a picture screen, which picture information comprises video information of a video program as well as control information for selectively displaying the video programme. The video programme is subdivided into sections (35) and, when the video programme is displayed selectively, sections are shown in a new order (34) and partly omitted or replaced. To this end the control information includes path information (36) which indicates a path of sections to be displayed in linked fashion. The path information may be recorded multiplexed with MPEG-2 video information and then contains addresses (53, 54, 55, 56, 57, 58, 59) for forward and backward jumps.
Abstract:
An option device area is provided for every partition so that loading/unloading can be performed in the areas. Data in required access positions are accessible based on unloading position information which is stored in the volume information of an MIC after the loading is effected in one of the option device areas and an area ID recorded on a magnetic tape. System log information is written in/read from the MIC, so that the time and number of actions required to perform an access are reduced.
Abstract:
When a user wants such a service as information presentation, video watching, or commodity ordering, the user connects a client computer to a server computer through a communication line, an entrance hall is displayed in a virtual space on the display of the client computer and a plurality of shops are displayed in a specific pattern in connection with the entrance hall. In an example of the specific pattern, the entrance hall is positioned on one side of a polygon and the shops are positioned on the other side of the polygon. The height of the entrance hall is adjusted so that the bird's-eye view from the entrance hall of the shops can be obtained. Therefore, the retrievability and functionality of three-dimensional GUI are improved. Moreover, the concept familiar to many users using two-dimensional GUIs is incorporated naturally.
Abstract:
A focus control circuit (34) which controls the focus of a video camera is provided with a horizontal-direction evaluation value generating circuit (62) which generates a plurality of evaluation values for the horizontal direction, a vertical-direction evaluation value generating circuit (63) which generates a plurality of evaluation values for the vertical direction, and a microcomputer (64) which performs a prescribed operation upon receiving the evaluation values for the horizontal and vertical directions. The circuit (62) generates the evaluation values corresponding to preset evaluation windows of different sizes. The microcomputer (64) selects evaluation values corresponding to an appropriate evaluation window for judging the contrast of an object out of the supplied evaluation values and controls the focus of the video camera based on the selected evaluation values. Therefore, appropriate evaluation values of the object can be obtained.
Abstract:
Individual frames of images recorded on an optical film are read by a scanner (11) and are converted to electrical image data, andthese data are stored in a main memory (21). A memory control portion (2) controls the read and write operations from and to the main memory 21 and forms an inverted image data by inverting the vertical direction of the image data. A system control portion (5)controls this memory control portion (2) in accordance with an inversion command from a keyboard (6) so as to obtain the inverted image data. Because the system control portion (5) controls the write and read operations to and from the main memory (21) in sucha manner as to invert the vertical direction of the image data inaccordance with the inversion command from the keyboard (6), the erect image of any frame can be displayed on a display portion (7) by giving the inversion command to the display portion (7) whenever an inverted image is displayed. Further, the erect images can be recorded to a recording medium by a disk drive (42).
Abstract:
A connector plug (41) in which a housing (78) having a plurality of contacts (82) in a socket inserting hole (81) is covered with a metal shell section (88) of a shield case (79). The metal shell section (88) is a square tube whose axis extends in the direction where the plug (41) is plugged and elastic parts (77) are provided in the direction of insertion of the plug (41). The elastic parts (77) swell out from both sides of the metal shell section (88), or is bent so as to curve outward the lower parts of both sides of the metal shell section (88). A cut (89) is made in the bottom part of the metal shell section (88) in the direction of insertion of the plug (41) so that the section (88) is elastic. When the connector plug (41) is inserted into a connector socket (42), the section (88) is securely connected to the socket (42) and the whole structure is compact, because the section (88) is elastic due to the elastic parts (77) of the section (88) and the clearance produced when the section (88) is inserted into the socket (42) is absorbed by the cut (89).
Abstract:
A video signal transmitter in which video data generated by means of an image pickup device is stored in a video data storing device, and the video data are edited by means of an editing device. Ancillary information is added when video data are generated, and extracted and used as keywords of a database in the video data storing device to edit video data. Hence, construction of a database and edition of video data are further facilitated and simplified.
Abstract:
Data in a management region of a tape are reliably restored by a retry processing even when a read error occurs due to scratches on the tape. A physical ID with an initial value of 4000ID from PBOT is set to -1600ID (Fig. 19A) after normal VSIT write, to -1700ID after the first retry (Fig. 19B) and to -1800ID after the second retry (Fig 19C), and it decreases by 100ID after each retry. In contrast, VSIT is always written from 0ID. In this way, in the retry processing of VSIT, the physical ID of the start position does not change, and the actual write position, that is, the distance from PBOT, can be changed. Therefore, even when the error of VSIT write occurs due to scratches of the tape, for example, the VSIT write error can be restored by this retry processing.
Abstract:
Signals (digital sine wave signals) (Sd) stored in a memory means (3) are read. The phase of input signal (analog sine wave signal) (Sr) supplied to an input terminal is compared with that of signal (Sa) generated by D/A-converting the signals (Sd) (by means of a comparator (2)), the reading address signal of the memory means (3) is controlled based on the phase error signal (a) generated as a result of the comparison by the comparator (2) (by means of an address forming circuit (5)). Thus, the phase of the digital sine wave signals (Sd) supplied to an output terminal (6) is synchronized with that of the analog sine wave signals (Sr) supplied to the input terminal (1). Desired digital signals synchronized with the phase of the input signals can be generated by processing the digital signals with a simple constitution.
Abstract:
An electronic appliance comprising a battery compartment for storing cylindrical batteries (cells) loaded from an opening of the appliance body and having a first terminal connected to one of the terminals of the cylindrical battery; a cover for closing the opening; a second terminal movable with the cover and connected to the other terminal of the battery when the cover is closed; and a connection mechanism being out of contact with the second terminal when the cover opens while making electrical contact with the second terminal when the cover closes. Here, the second terminal includes a protruding portion that comes into electrical contact with the connection mechanism when the cover closes, and a fitting portion to which the cover is movably attached. The electronic appliance further comprises a retaining mechanism for keep the cover closed when the retaining mechanism is moved to the second terminal to close the opening.
