    摘要： A disc-shaped information recording medium includes a laminate of recording layers on and from which an information signal can be optically recorded and reproduced from one side of the medium. Data areas are provided in the recording layers, respectively. The information signal can be recorded on and reproduced from the data areas while a laser beam emitted from an optical pickup is applied to the data areas. Optical recording test areas are provided in the recording layers, respectively. A test signal can be recorded on and reproduced from the optical recording test areas to decide optimum power values of the laser beam for signal recording. The test areas are out of overlap as viewed in a direction of propagation of the laser beam.

    摘要： Audio data representative of a music piece is converted into data components in respective different frequency bands for every unit time interval to generate time frequency data pieces assigned to the respective different frequency bands. From the generated time frequency data pieces, detection is made as to each sustain region in which an effective data component in one of the frequency bands continues to occur during a reference time interval or longer. A feature quantity is calculated from at least one of (1) a number of the detected sustain regions and (2) magnitudes of the effective data components in the detected sustain regions. The music piece is classified in response to the calculated feature quantity.

    摘要： A headphone has a speaker unit with a diaphragm and a driving source that vibrates the diaphragm along a driving axis that passes through the speaker unit. The speaker unit has a first face and an opposing second face along the driving axis. The diaphragm and the driving source are installed in the speaker unit between the first and second faces. First and second weighting members are fixed as being in contact with the first and second faces, respectively. The speaker unit and the weighting members are installed in a housing. At least either of the weighting members is fixed to the housing. The speaker unit is installed in the housing via the weighting members so that the speaker unit is not in direct contact with the housing. The weighting members have a higher specific gravity than the housing.

    摘要： An information recording medium includes a recording area for an auxiliary signal, and a recording area for a main signal. The auxiliary-signal recording area and the main-signal recording area are successively arranged. The main-signal recording area stores first information, second information, and third information. The first information represents plural tunes. The second information includes playback control information for separating the tunes into groups and implementing playback of the tunes group by group. The third information includes interactive data for permitting an access to the first information of the tunes group by group.

    摘要： A video signal is encoded at a plurality of coding layers exhibiting different spatial resolutions. An input video signal is spatially scaled down into a resolution-lowered video signal that exhibits a resolution lower than the video signal. The resolution-lowered video signal is encoded with a decoding procedure to obtain first coded data and a decoded signal. The decoded signal is spatially scaled up through a high-resolution procedure with reference to the input video signal so that the decoded signal has a smaller error with respect to the input video signal, to obtain a high-resolution scaled-up video signal. The input video signal is encoded through inter-spatial resolution prediction using the high-resolution scaled-up video signal as a predictive signal, to obtain second coded data that exhibits a resolution higher than the resolution-lowered video signal.
