An information processing apparatus capable of simultaneously executing a reproduction function of content data and a communication function with an external apparatus includes a reproduction section configured to execute the reproduction function, a communication control section configured to execute the communication function using a communication section, an operation input allocation section configured to allocate an operation input from a first operation section to the reproduction function or the communication function, an operation input acquisition section configured to acquire an operation input from a second operation section, and a display control section configured to cause a display section to display information relating to the reproduction function or information relating to the communication function.

Information processing apparatus, information processing method and program

Disclosed herein is an information processing apparatus capable of exchanging information with another apparatus. The apparatus includes: a unit for carrying out a communication with the other apparatus; a unit for acquiring information on a state of a communication with the other apparatus carried out by the communication unit; and a unit for determining image information for a user owning the other apparatus based on the information acquired by the communication-state information acquisition unit and determining an array including the image information. The apparatus further includes: a unit for generating a display image including the image information based on the array; and a unit for displaying the display image.

Information processing apparatus, information processing method, information processing program and recording medium for storing the program

An information processing apparatus capable of simultaneously executing a reproduction function of content data and a communication function with an, external apparatus includes a reproduction section configured to execute the reproduction function, a communication control section configured to execute the communication function using a communication section, an operation input allocation section configured to allocate an operation input from a first operation section to the reproduction function or the communication function, an operation input acquisition section configured to acquire an operation input from a second operation section, and a display control section configured to cause a display section to display information relating to the reproduction function or information relating to the communication function.

A reproduction apparatus for an optical recording medium that has a convex pit recording layer, in which pits are formed in a convex shape viewed from a laser incidence side, and a concave pit recording layer, in which pits are formed in a concave shape viewed from the laser incidence side, as recording layers in which data is recorded by pit strings, the pits being formed with a depth that is set in a range of &#x3bb;/4.5 to &#x3bb;/6 with respect to a laser wavelength &#x3bb;, including: an optical head section that irradiates laser beams on the recording layers and detects reflected light information to read out information recorded in the recording layers; a tracking error signal generating section that generates a tracking signal; a polarity switching section that switches a polarity of the tracking error signal; and a tracking servo section that performs a tracking servo operation.

Optical recording medium, reproduction apparatus, and tracking servo method

A portable recording and/or reproducing apparatus for recording and/or reproducing data to and/or from a storage medium are provided. The medium has a data area and a management area. The data area stores data and the management area stores management information for managing the data. The apparatus includes stopping means for stopping reproduction of the data according to a user's input. Updating means for updates the management information so that an address of the storage medium corresponding to the stop position of the reproduced data determined by the user's input becomes the end address of the reproduced data.

Recording and / or reproducing apparatus and editing method

The invention provides a reproduction apparatus that reproduces information recorded in a recording medium having plural recording layers, including: an optical head that irradiates laser beams on the respective recording layers and detects reflected light information to read out information recorded in the respective recording layers; a shaft sliding type focus actuator that holds the object lens; a focus servo section that generates a focus servo drive signal and drives the focus actuator such that a focus state of the laser beams is kept in a state of focus on a recording layer on which the reproduction is performed; and a focus jump control section that generates a kick signal for starting focus jump movement by the focus actuator and a brake signal for ending the focus jump movement.

Reproduction apparatus and focus jump method

A recording and/or reproduction apparatus for recording and/or reproducing data onto and/or from a storage medium is disclosed. The recording and/or reproduction apparatus includes a recording and/or reproduction section for recording and/or reproducing data onto and/or from the storage medium, a communication section for communicating with an external apparatus, a memory for storing operation screen information corresponding to the recording and/or reproduction section, a transmission controller for controlling the communication section to transmit the operation screen information to the external apparatus, and a controller operable when the communication section receives operation information to the operation screen information displayed on the external apparatus for controlling the recording and/or reproduction section in accordance with the operation information.

Recording and/or reproduction apparatus and recording and/or reproduction method

Recording and/or reproducing apparatus and editing method

The invention provides an apparatus and method which allows playback of both of a first optical disc wherein the opposite side faces of a groove formed thereon are wobbled at a first predetermined frequency and a second optical disc wherein one of the opposite side faces of a groove formed thereon is wobbled at a second frequency shorter than the first predetermined frequency while the other face of the groove is formed as a flat face. In the apparatus and method, it is discriminated whether an object optical disc of playback is the first optical disc or the second optical disc, and various servo systems are switched based on a result of the discrimination.

Tracking system for a reproducing apparatus switchable between first and second tracking controls based on discriminating between first MD type 1 and second MD type 2 optical discs

Reproduction apparatus and reproduction method

A signal processing circuit for a video camera includes: a voltage controlled oscillator for controlling an oscillation frequency in accordance with a control signal, a synchronism generation circuit for generating a synchronizing pulse signal in accordance with an output signal of the voltage controlled oscillator, and a phase comparison circuit for comparing the phase of the synchronizing pulse signal being output from the synchronism generation circuit with a signal corresponding to the phase of an AC utility power source. The voltage controlled oscillator is controlled by the output signal of the phase comparison circuit, and in turn controls the synchronism in accordance with the phase of the AC utility power.
