Abstract: In a headphone which inhibits noise generated within an ear structure by vibration transmitted through bone, head motion based on vibration is detected by a motion sensor, and a motion signal is output. This motion signal is delayed by a delay time, and the phase of the motion signal is inverted to generate a first noise cancelling acoustic signal in the first cancelling circuit. An acoustic driver of the headphone is driven by the first noise cancelling acoustic signal to inhibit noise.

Abstract: According to one embodiment, a data reproduction apparatus comprises a reproduction module configured to reproduce image data, a resolution selection module configured to select one of resolutions, an image quality mode selection module configured to select on or off state of an image quality mode, a selection disable module configured to disable the resolution selection module to select a prescribed resolution when the image quality mode selection module selects the on state of the image quality mode, and an image processor configured to improve a quality of the image data reproduced by the reproduction module in accordance with the resolution selected by the resolution selection module when the image quality mode selection module selects the on state of the image quality mode.

Abstract: Upon reception of digital broadcast, system clocks which follow PCR data of an MPEG2-TS are provided. Upon disc playback, system clocks as fixed clocks are provided. To this end, upon processing the MPEG2-TS, first clocks CK1 synchronized with the PCR data are generated. If the user designates playback using high-precision clocks, third clocks CK3 as fixed clocks are generated. If the user does not designate any high-precision clock playback, clocks CK1 are generated. When use of clocks CK1 is stopped, clocks CK3 are generated after second clocks CK2 synchronized with clocks CK3 are mediated.

Abstract: A clock generating apparatus includes a first PLL circuit configured to generate a sync clock in phase with reference time information from a data stream, an oscillator configured to generate a fixed clock, a control unit configured to output a clock switching signal, and a clock switching unit configured to selectively switch the sync clock and the fixed clock to each other in accordance with the clock switching signal and output the selected clock as a system clock.

Abstract: A digital data output circuit generates video and audio data. An HDMI LSI generates transmission video and audio data by alternately arranging the video data and audio data generated from the digital data output circuit. An LSI control portion outputs a data switching signal which is used to switch the transmission video and audio data. Further, the HDMI LSI selects and transmits one or both of the generated video and audio data in accordance with the data switching signal from the LSI control portion.

Abstract: It is easy to reproduce a recorded information and, particularly, its portions on a disc, in a repeated fashion and the disc is convenient to learn. It is proved effective to perform reproduction, while picking up only a specified portion of a plurality of programs in the recorded information on the disc, and to conduct a search for a program while viewing it. The disc (100) includes a plurality of programs recorded thereon and voice information written in an order of phrase units, chorus units and sentence units. A reproduction apparatus is of such a type that, upon detecting the flag, an address of corresponding voice information is recorded and updated and, upon the entry of a repeat command, a shift is made back to the address so that repeat reproduction may be made.

Abstract: Display is made according to the user's request by using the time information recorded on the disk. A disk contains a management area in which management data is recorded and a data area in which programs are recorded. Recorded in the management area are the absolute time information on the starts of the programs and the in-program relative time information on the starts of data units constituting each program. In the absolute time display mode, the absolute time information for display is obtained from the absolute time information on the program being reproduced and the relative time information on the data unit of the program being reproduced. In the relative time display mode, the absolute time information of the program being reproduced is set at 0, and the absolute time information for display is obtained from the relative time information on the data unit of the program being reproduced.

Abstract: A desired frame image can be searched for and reproduced at high speeds. The same holds true for frame return reproduction. A data unit containing the video information compressed by encoding is stored in a data unit memory and decoded at a decoding unit. When the target frame is decoded, the decode output is stored in an image memory and supplied as a still reproduction image via a switch. The image memory can also be used as a memory for storing the decode output of the frame located at the mid-point between the start frame of the data unit and the frame currently being reproduced.
