Abstract: Music contents assigned to play lists are reproduced so as to correspond to user's preference. A music content database 7 has stored a plurality of music contents. A CPU 3 creates genre ranks such that music contents that have been more frequently, for example, reproduced are more highly ranked. In addition, the CPU 3 creates play lists corresponding, for example, to tempos and stores the created play lists in a play list database 8. The CPU 3 selects a play list corresponding to a moving tempo obtained from a tempo detection section 9 and selects music content categorized as a highly ranked genre in the genre ranks from those corresponding to the selected play list. The selected music content is supplied to a decoder and amplifier section 12 and then reproduced from a head phone 14.

Abstract: Content is selected on the basis of changes of a walking tempo. The walking tempo is detected (S5). In a state determination process (S7), it is determined whether the walking tempo tends to increase, be constant, or decrease. A walking tempo corrective coefficient is calculated on the basis of the determined result and a corrective walking tempo is calculated with the walking tempo corrective coefficient (S9). It is determined whether or not music is changed on the basis of the corrective walking tempo rather than the actually detected walking tempo (S11). When music is changed, relevant music content is searched. Controls are performed in such a manner that when the walking tempo is decreasing, the foregoing state is kept for a while, when the walking tempo is increasing, music is quickly selected according to the increase of the walking tempo, and when the walking tempo is stable, music is not selected.

The data processing apparatus encrypts subject data and renders it as encrypted data to record it on a predetermined recording medium, and decrypts the encrypted data recorded on the recording medium to change it back to the subject data. The encryption is performed in units of plain text cut data generated by cutting the subject data by a predetermined number of bits, where the number of bits of the plain text cut data is varied and dummy data of a size having the number of bits matching with a piece of the plain text cut data of the largest number of bits is mixed with pieces of the plain text cut data other than that of the largest number of bits out of the plain text cut data.

Abstract: Channel estimates calculated by a channel estimator (32) are linearly interpolated (34). When transmissions from transmitting antennas are stopped due to a deterioration of the propagation environment, since a larger amount of computing resources become available for use, a channel estimate selector 36 selects the linearly interpolated channel estimates and supplies them to an MIMO demultiplexer 38 which can thus cope with fast fading.

Abstract: A data communication apparatus capable of creating a new type of communication is provided. Motion information obtaining means 33 obtains information on the motion of an arbitrary apparatus. An other-party apparatus motion determination section 21 makes a determination as to the motion of the arbitrary apparatus on the basis of the information on the motion of the arbitrary apparatus, the information being obtained by the motion information obtaining means 33. A communication determination section 22 determines whether or not communication is to be performed with an arbitrary apparatus on the basis of the motion determination output by the other-party apparatus motion determination section 21. When it is determined by the communication determination section 22 that communication is to be performed, predetermined data communication is started with the arbitrary apparatus.
