An image analysis unit that detects a user's point of gaze with respect to display information of a display unit on the basis of an image captured by a camera, a user attention information analysis unit that extracts attention information on which a user's point of gaze had been for a prescribed length of time or longer and generates a list including information corresponding to the attention information, and a display information generation unit that generates a display list including list configuration data. The user attention information analysis unit continuously inputs user's point-of-gaze information, and executes sorting processing for setting, in the top of the list, latest attention information or attention information on which the user's point of gaze is for a long length of time. The display information generation unit generates a display list including top data of list configuration data, for example.

An optical disc apparatus includes: a section for controlling an actuator by generating a voltage indication value indicative of a drive voltage applied to the actuator driving an objective lens; an section for periodically detecting the voltage indication value; a section for going into an excess detection mode when the voltage indication value outside a tolerable range is detected, and starting a re-detection period when the voltage indication value inside the tolerable range is detected, and remaining in the excess detection mode and extending the re-detection period when the voltage indication value outside the tolerable range is detected during the re-detection period, and stopping the excess detection mode when the voltage indication value outside the tolerable range is not detected again during the re-detection period; and an section for limiting the voltage indication value when staying in the excess detection mode for longer than a fail-safe action start period.

The present invention decreases the processing load of the content provision apparatus when providing the content data. An apparatus according to the present invention acquires the content-provision addresses and data-size information corresponding to the content data from the acquisition utilization information provision server. The apparatus then determines the division-start positions and division-end positions for the content data, based on the content-provision addresses and data-size information. The apparatus subsequently transmits to each content provision serverA throughN the division-part-request information including the division-start positions, the division-end positions and the content-identification information. After that, the apparatus receives each division part from the content provision serversA throughN and restore the content data. In this manner, the apparatus specifies the content data, the division-start positions and the division-end positions. In response to that, each content provision apparatus transmits the division part whose data size is smaller than the content data. That reduces the processing load of the content provision apparatus.

Content acquisition method

An encoding apparatus for highly efficiently encoding an input digital signal includes a band dividing means, an encoding means, a normalization processing means for normalizing a signal component of each block encoded by the encoding means and generating a normalization signal, a quantization coefficient calculating means, a bit allocating means for deciding the number of allocated bits for each block corresponding to the quantization coefficients calculated by the quantization coefficient calculating means, a normalization information changing means for gradually changing the normalization information generated by the normalization processing means corresponding to a user's operation on a time base, and an encoded data generating means.

Encoding apparatus, decoding apparatus, decoding method, recording apparatus, recording method, reproducing apparatus, reproducing method, and record medium

Reproducing method and apparatus for reproducing highly efficiently encoded data from a record medium composed of spectrum data and scale factor data determines if address of changed highly efficient encoded data and stores it. The method and apparatus determines whether or not the address of highly efficient encoded data whose scale factor data is changed corresponding to the operating mechanism and stores it in a memory store apart from the write address by a predetermined distance. By partly changing the scale factor values and filtering process is accomplished.

Reproducing apparatus and reproducing method

The present invention is an editing apparatus and an editing method for allowing the user to designate a desired portion of a particular program recorded as a highly efficient encoded digital signal on a record medium, reproducing the portion designated by the user, changing normalization information contained in the reproduced digital signal, performing a sound field process for the digital signal, and recoding the resultant signal to the record medium, wherein the record position of the program is edited corresponding to the designated portion.
