  • Patent number: 6681076
    Abstract: A first rotational head of a first azimuth angle and a second rotational head of a second azimuth angle are arranged on a rotational drum rotated at a constant rotational speed. Also, input digital signals are processed in a signal recording system to form blocks of digital recording signals, a magnetic tape is moved by a tape driving unit according to an information signal generated in a control unit, and the blocks of digital recording signals and the information signal are recorded on the magnetic tape in a recording operation through the first and second heads alternately tracing the magnetic tape. In a reproducing operation, the signals are read through the first and second heads and are reproduced in a signal reproducing system. When the input digital signals are transmitted at a standard data rate, the magnetic tape is rotated at a first traveling speed in the recording and reproducing operations.

  • Patent number: 6647378
    Abstract: A method and apparatus are provided of adapting a dictionary into which a keyword effective for judging whether or not information provided from either one of an information recording medium or an information communication network is recorded preferentially. The information includes information data and one or more keywords attached to the information data. The method is implemented by providing a user with the information data, enabling the user to input a signal indicating that the provided information data is necessary or unnecessary; calculating a prediction value for predicting a user's necessity degree of each keyword attached to the provided information data on the basis of the signal inputted in the inputting step, and registering preferentially the keyword effective for the dictionary by using the prediction value.

  • Patent number: 6552825
    Abstract: A data communication apparatus such as a facsimile apparatus having an automatic telephone message recording function, having a common memory for storing video and audio data that have been received or are to be transmitted, enables selection of a method of memory management whereby the memory space is divided at a boundary address into two regions which respectively store video data and audio data and a method whereby the memory space is not so divided, but the video data and audio data are written into addresses which successively increase from respectively opposite ends of the memory space. Remaining amounts of memory capacity which can be used to store video and/or audio data can be displayed as respective numbers of standard document pages and telephone calls, the latter representing standard-duration recording intervals.

  • Patent number: 6487564
    Abstract: A multimedia playing apparatus plays hypermedia titles each consisting of a plurality of monomedia objects including at least one finite time monomedia object such as a video object, which is formatted as a sequence of fixed-length playing sections such as video frames and functions as a base-axis object for providing a timing reference. The apparatus executes playing of a hypermedia title in accordance with processing time points specified as respective numbers of the playing sections, and stores and utilizes a plurality of sets of synchronization trigger data each of which designates that playing of a specific monomedia object other than the base-axis object is to be started, or is to be ended, at a specific processing time point, with the synchronization trigger data sets being successively accessed and used as the corresponding processing time points are respectively reached during playing of the hypermedia title.

  • Patent number: 6414720
    Abstract: A digital broadcasting system capable of causing any of physical channels selected by a broadcaster to be received as one of the channels available to users which is different from the physical channel selected by the broadcaster. For each of programs of each of the channels available to said users, a program information record comprising PSI (program specific information) is stored in a data base. The broadcaster is permitted to include, in the PSI, channel mapping information whose mapping destination is a channel (or a program) to be received instead of the channel for which said program information is intended. The program information records is inserted in broadcast transport streams on schedule and, if necessary, immediately after the broadcaster have included the channel mapping information in the PSI data.
