Abstract: A sensitivity fable is prepared, and this sensitivity table contains correlative values between respective retrieve keywords (for example, “cheerful music piece”, and “energetic music piece”) and respective feature words (for instance, “cheerful” and “vitality”), and also may be updated. A feature word list is prepared in which symbols “1” and “0” denote as to whether or not a feature related to each of these feature words is present. When a user inputs a desirable retrieve key, a plurality of music pieces which are fitted to this, retrieve key are selected on the basis of both the sensitivity table and the feature word list. A feature in sensitivities of the user is extracted in a quantitative manner by a statistical manner by judging as to whether or not these music pieces are skipped by the user on the basis of individual judgment by the user. The correlative values of the sensitivity table are updated based upon this feature.

Abstract: A positioning apparatus and method for accurately determining a current position of a mobile station. The current position of the mobile station is determined utilizing radio waves arriving from a plurality of base stations installed in a communication area. For calculating a propagation range of a radio wave arriving from each base station, error correction processing is performed using a predetermined error correction coefficient previously calculated by measuring a radio wave propagation situation around each base station to estimate a propagation range of a direct wave within incoming radio waves. The current position of the mobile station is determined using the estimated propagation range and the positions of the respective base station.

Abstract: A receiving device is provided with a DLL circuit of a reduced scale. An inverse spreading processing to ensure the synchronism with a received signal and a processing to inversely spread original data in the received signal are performed by a time-sharing operation using one inverse spreading circuit and one integrator. During a period in which synchronous data for detecting a slot duration included in the received signal is received, the synchronous data is alternately inversely spread by an early code and a late code and sample-hold circuits alternately sample and hold the integrated output. Further, based on the difference (error signal) between sample-hold signals, the early code, the late code and a reference code outputted from a code sequence generator are synchronized with the received signal.

Abstract: A video signal recording and reproducing system enables recording and reproducing of a video signal with high quality. The system includes a recording system for recording the video signal on a record medium by a median filter and a reproducing system for reproducing the video signal from the record medium. The recording system separates a brightness signal and a color signal from an interlaced scanning signal. The recording system divides picture elements of each line into two phases by sorting the elements such that an element is put into one phase and the next element into the other. The recording system then carries out two-dimensional subsampling to the brightness signal and the color signal to reduce the amount of data. Then, the recording system compresses and time-division multiplexes the brightness signal and the color signal to provide a video signal to be recorded onto a record medium.
