Abstract: An index related process unit 75 in a web server 3 determines index related information regarding a display form of a VD index picture, which is necessary for a GUI data generating unit 77 to generate GUI data. The index related information includes, for example, the number of VD index pictures which can be displayed according to the size of a browser screen of a terminal device 4, numbers of VD index pictures to be selected when the number of VD index pictures generated exceeds the displayable number, and a VD index picture display form according to the length of a moving picture. The VD index picture display form is used so that the user of the terminal device 4 can recognize the length of the corresponding moving picture only by seeing the VD index picture display form displayed on the browser screen by selectively using a part of the area in which the VD index pictures can be displayed according to the length of the moving picture.

Abstract: An apparatus and a method for processing information, and a program and a program storing medium are disclosed in which a user can surely recognize the change of images when they are operated. Upon detection of an operation, a processing manager applies, every predetermined period, a transition function to an elapsed time from the detection of the operation to compute a ratio of the movement of an image to a distance from the current position of the displayed image to a destination specified by the operation. On the basis of the obtained ratio of the movement of the image, the processing manger specifies a display position of the image toward the destination. A content processing routine controls the display so that the image is displayed at the specified position every predetermined period.

Abstract: A technique for calibrating a N-port receiver, such as for example a 5- or 6-port receiver is proposed. The N-port receiver (1) comprises a first input (2) for a RF signal to be detected, a second input (3) for a RF signal originating from a local oscillator (4) and N−2 output terminals. Calibrating signals are generated on the basis of the RF signal supplied by the local oscillator (4). The calibration signals are fed to the first input (2) and/or the second input (3) of the N-port receiver (1). Calibration coefficients are calculated on the basis of the output signals generated by the N-port receiver (1) in response to the feeding of the calibration signals. The calibration signals are unmodulated signals and are only processed by means of a passive RF circuitry in the calibration device (100). The solutions according to the present invention allow a simple calibration of N-port receivers, which can be used as IQ demodulators or converters.

Abstract: The present invention is intended to provide a delay lock loop circuit which is capable of providing a minute delay amount with stability regardless of the variations in delay amount due to variations in temperature and power supply voltage for example and process conditions. On the basis of a up/down control signal from a delay amount detector, count value is counted from initial setting value up to maximum setting value or down to minimum setting value. When the count value has reached the maximum or minimum value, another count value is counted up and down, thereby cutting the noise component of the up/down control signal. Consequently, regardless of the variation in delay amount due to a delay line, a delay lock detector to which the latter count value is supplied operates normally, thereby outputting with stability a reference delay step count for obtaining a delay of 1T.

A receptacle for the memory card is also disclosed. The memory card has a simple structure designed to positively protect the terminals and easily let out dust or the like from inside, thereby permitting to assure a positive connection with the receptacle.

Abstract: Picture image data having high image quality is recorded in a disk-shaped recording medium such as a hard disk and a removable disk. A recording apparatus is arranged by a first unit for recording image data with respect to a disk-shaped recording medium in which an outer peripheral sided region thereof is recordable/reproduceable at a higher rate than that of an inner peripheral sided region thereof, and a second unit for designating an attribute of image data recorded in the disk-shaped recording medium. When the second unit designates image data having a large data amount per unit time, the first unit records the image data having the large data amount per unit time in the inner peripheral sided region of the disk-shaped recording medium, whereas when the second unit designates image data having a small data amount per unit time, the first unit records the image data having the small data amount per unit time in the inner peripheral sided region of the disk-shaped recording medium.

Abstract: An electronic device has memory (configuration ROM) which is directly accessible from another electronic device. The memory has an area (for example, a “Model_ID” entry of a root directory) to store its own model information and another area (for example, a Model_ID” entry of a module information directory) to store model information of a module to which the electronic device is connected. The information pointing to a storage location of the module information directory is set at a “Module_info” entry of the root directory. The model information includes model ID for identifying models and user interface information for describing models (textual data and icon data). When another electronic device accesses the memory, it aquires the above information. This allows it to easily aquire model information of the module to which the electronic device is connected.
