摘要： A data compressing unit compresses information data inputted from an input unit. An input buffer unit temporarily stores the compressed data obtained by the data compressing unit. A recording/reproducing unit records the compressed data read out from the input buffer unit onto a recording medium, and reproduces the compressed data recorded on the recording medium. An output buffer unit temporarily stores the compressed data reproduced by the recording/reproducing unit. A data expanding unit expands the compressed data read out from the output buffer unit. An output unit outputs data expanded by the expanding unit. For this reason, when one set or cluster of information data is assumed to be information data file, it is possible to reproduce, without necessity of interruption of recording of the entirety of the information data file, the portion recorded earlier, e.g., by several minutes to several tens minutes within the same information data file.

摘要： A matrix switcher selectively seizes plural compressed pictures and converts P-frames in a GOP into I-frames while modifying prediction data of B-frames in the GOP. A decoder expands the compressed pictures into original pictures. An input buffer memory converts the picture signals into component signals while converting the transfer rate. A picture processing unit performs various picture signal processing operations on the picture signals. An encoder encodes the processed picture signals for compression. An output buffer memory converts the transfer rate of sent-out data which are compressed processed signals. A controller controls processing operations by the matrix switcher, decoder, input buffer memory, picture processing unit, encoder and the output buffer memory. The compressed pictures processed by inter-frame compression can be switched smoothly. Moreover, picture processing can be performed on a wide gamut of pictures from still pictures to moving pictures, free-format pictures, pictures not dependent on transfer rate and on scalable-format pictures.

摘要： An information signal transmission device in which information signals are transmitted to requesting parties responsive to requests made by plural requesting parties. The signals of the leading end of the information signals are pre-stored in a versing-up memory and, when a request is made by a requesting party, an output signal of a buffer memory unit for time axis expansion is transmitted to such requesting party after an output signal of the versing-up memory unit is transmitted to such requesting party.

摘要： Disclosed is a method for interchanging contents information and a system for interchanging contents information. A loop that a receiving side CL1 sends a request signal CL1a carrying position data pd to a sending side SV1 through a communication system NT, the sending side SV1 sends back contents information corresponding thereto as a sending signal SV1a, and the receiving side CL1 displays the signal is repetitively updated and performed at a high frequency by repetitively updating and sending the position data pd at a high frequency. Since the achievable frequency of repetitive updating and performing the loop varies by the combination of receiving side CL1, communication system NT, and sending side SV1, the achievable maximum frequency mxfQ for each loop is determined from a given table or by actual measurement. A standard frequency stfQ which does not exceed the thus determined frequency is set, the processes along the loop are performed at the standard frequency stfQ or a lower frequency. As a result, power consumption is reduced and communication load is mitigated.
