Abstract: The present invention describes a network system, comprising at least two network units, of which at least the first network unit is provided with an insufficient amount of memory space, wherein the first network unit, which comprises said insufficient amount of memory space, is able to create a program object through the network to a second network unit which comprises a sufficient amount of memory space.

Abstract: A GPS receiver communicates with a management center through a portable telephone terminal. The management center is connected to a telephone unit and a facsimile unit in a house through a telephone line. When the user presses a predetermined button with the telephone unit, a request for location information of the receiver is transmitted to the management center. The management center transmits the location information request as a DTMF signal to the receiver. The receiver measures the location thereof. The measured result and time information of a navigation message thereof are transmitted as a DTMF signal. When the management center determines that the message is old corresponding to the time information, the management center compensates the measured result. The management center transmits the location information to the telephone unit. The management center transmits image data with map information to the facsimile unit.

Abstract: A data processing apparatus for coding data includes a coder for generating third data by coding first data and second data. A decoding-information generator generates decoding information, the third data being decoded into the first data and the second data based on the decoding information. An embedding coder embeds the decoding information generated by the decoding-information generator into the third data, thereby generating embedded data.

Abstract: A subordinate low pass filter 21 having characteristics similar to those of a main low pass filter 11 is provided. A signal of a frequency corresponding to a cut-off frequency is supplied from a signal generating circuit 22 to the subordinate LPF 21. A phase difference detecting circuit 23 detects a phase shift amount which is caused when the signal of the cut-off frequency is supplied to the subordinate LPF 21. An error detecting circuit 24 compares a value corresponding to the phase shift amount caused in the subordinate LPF 21 when the signal of the cut-off frequency is supplied with a reference value corresponding to the phase shift amount to be caused in the subordinate LPF 21 at the time of the cut-off frequency on phase characteristics. A comparison output is used as a control signal and the subordinate LPF 21 and main LPF 11 are controlled to have a desired cut-off frequency.

Abstract: An audio signal and a video signal are recorded onto a hard disk. In the hard disk, by time-divisionally processing the recording and reproduction, they are executed in parallel. Audio data as much as four fields and corresponding video data as much as one field are constructed as one set and are time-sequentially recorded. In a one-time speed reproduction, the data is reproduced every set. The video data is repetitively reproduced for a period of time of four fields. In a double-speed reproduction, the video data is reproduced every other data and the audio data as much as four fields corresponding to the video data which is reproduced and the audio data as much as subsequent four fields are reproduced. To reproduce the audio data as much as eight fields for a period of time of four fields, the speed of the audio data is converted to a double speed and the audio data is continuously reproduced.

Abstract: The present invention relates to a signal recording and reproducing method used for video tape recorder. An erasing position precedes a recording position and a reproducing position precedes the erasing position. By using a period when reproducing does not reproduce a signal recorded on a track of a tape-like storage medium, the period occurring during recording and reproducing operation, recording apparatus records a signal on a recording track or erasing apparatus erases a signal recorded on a recording track. Hereby, if a signal recorded on a recording track of the tape-like storage medium is processed and replaced, the signal recorded on the recording track of the tape-like storage medium can be satisfactorily reproduced without being influenced by signal recording operation and signal erasing operation.

Abstract: A receiver for broadcast signals, e.g. DAB, FM, DVB, and digital or analog short-wave RF broadcast signals according to the present invention includes a polyfunctional circuit (5) that can be switched into three modes and performs the digital frequency demodulation which is needed for the reception of a frequency modulated signal in a first mode A, a digital frequency adjustment of the receiver in case of the reception of a digital or analog modulated broadcast signal like DAB, DVB, DRM or AM in a second mode B and the digital frequency adjustment and the digital gain control of the receiver which is needed in case of the reception of a digitally modulated broadcast signal like DAB, DVB, DRM in a third mode C. Depending on the needed functionality not all of these modes need to be realized. Nevertheless, the same hardware will be used for different purposes although the circuit is realized with an optimized amount of hardware to realize an efficient receiver.

Abstract: Pieces of address information are recorded on an optical disc such that they are successively continuous addresses within each zone but discontinuous at a beginning of a zone next to the previous zone, and an address after repeating the addresses of the previous zone for two rounds becomes the forefront address of the zone next to the previous zone. Access to the land tracks is performed by returning to the first address position in a zone after the addresses of the groove tracks become the last address of the zone, and the access is performed by recognizing an address continued from the last address of the groove tracks suppositionally on the pieces of address information recorded on the groove tracks, and then the access is successively performed to move to the next zone after the addresses of the land tracks become the last address of the zone.

Abstract: In a demultiplexer, picture signals of channels included in an input transport stream are separated from each other and supplied to VBV buffers for the respective channels to be stored therein. Picture signals read out from the VBV buffers are supplied to a signal switch for selecting one of the signals in accordance with a switch changeover signal generated by a switch controller. The selected picture signals selected from the VBV buffers are supplied to a variable-length decoder for decoding the signals on a time-division basis. Decoded picture data of a channel is selected by another signal switch in accordance with another switch changeover signal generated by the switch controller and supplied to one of picture memories for the channel to be stored therein. A display controller reads out a plurality of picture signals from the picture memories synchronously in accordance with a display timing signal generated by a display controller.

Abstract: A system controller directs a storage device to output a scene description data corresponding to a user request signal. A parsing circuit extracts a URL (Uniform Resource Locator) included in the scene description data, and causes storage devices to output elementary stream and object stream corresponding to the URL. After extracting an object descriptor from the object stream, a generator generates an ID of this object descriptor and supplies it to an encoder. Further, the generator adds the ID to the object descriptor and outputs the ID-added object descriptor to a multiplexer. The multiplexer multiplexes the scene description data including the ID that has been converted into binary format, the object descriptor and the elementary streams into a multiplexed stream for output thereof.

Abstract: A digital video processing system and method for deriving an output compressed video signal from an input compressed video signal. The input compressed video signal represents successive input pictures. Subsets of the input pictures are derived from other input pictures according to input picture motion vectors corresponding to a repetitive GOP (Group of Pictures) structure. The output compressed video signal represents successive output pictures, subsets of the output pictures being derived from other output pictures according to output picture motion vectors corresponding to a repetitive GOP structure that is different from, or not picture-aligned with, the GOP structure of the input compressed video signal. The output picture motion vectors are derived from the input picture motion vectors.

Abstract: In order to prevent meaningless data from being displayed when the data stored in the memory of tag cannot be displayed, the following is performed. When it is judged that matching of character set information intrinsic to the information processing apparatus and that stored in the tag is not attained, the read writer reads, from the tag, the alternative data different from the data to be displayed intrinsically, converts the data to the predetermined format and then supplies this data to the OSD section. The OSD section converts the data supplied to the data which can be displayed, causing the display section to display this data. Moreover, the read writer generates the warning display data suggesting that matching of character set information is not attained and then supplies this data to the OSD section. The OSD section causes the display section to additionally display the warning display data to the display image.

Abstract: At the time of call arrival, when the user of a telephone terminal depresses a response key or performs some other tentative responding manipulation instead of lifting up a handset, the telephone terminal transmits a self-introduction request message to the caller. A self-introduction voice transmitted from the caller in response is emitted from a speaker. Listening to the self-introduction voice, the user identifies the caller. If the user wants to talk to the caller, he depresses a communication key or lifts up the handset as a true responding manipulation and then starts a communication with the caller. On the other hand, if the user does not want to talk to the caller, he depresses an automatic answering mode setting key or a disconnection key.

Abstract: A cassette library (1) is provided with a driving apparatus (13), cassette housing shelves (14, 15) and a cassette carrier (16). A library controller (2) simulates as if driving apparatuses (13) having continuous address numbers were apparently used in the host computer (3) even when physically discontinuous address numbers are allocated to the driving apparatus (13), thereby making it possible to set occupancy for a driving apparatus with an arbitrary address number. The library controller (2) has the cassette carrier (16) automatically carry, at a preset timing, a cleaning cassette from the cassette housing shelf (14, 15) to the driving apparatus (13) to clean a recording reproduction head of the driving apparatus (13) using the cleaning cassette which is then carried back to the housing section in the original cassette housing shelf (14, 15) after the cleaning work.

Abstract: Video data inputted from an input terminal 32 is equally divided and recorded on disk drives 18a to 18c, respectively. The video data recorded on the disk drives 18a to 18c is sent out to a data bus 30 at a predetermined timing in accordance with a transfer control command from a data transfer controller 22, and image-processed by a switcher/digital multi-effector 13. Plural channels of video data are laid out in plural time slots formed by dividing a transmission unit having a length equal to a period forming one horizontal line prescribed by a predetermined analog video signal standard, and each channel of video data at least for one frame is transmitted with the transmission unit having a number of lines corresponding to one frame of the analog video signal standard. Thus, a digital data transmission method which enables high-speed synchronous transfer of video data and a data editing device which enables linear editing and non-linear editing may be provided.
