A video signal is processed to selectively permit copying by superposing in that portion of the video signal which does not contain useful picture information a copyright information signal indicative of whether the viewable picture that is displayed from the video signal is subject to copyright and a copy generation signal indicative of the number of successive generations of copies that can be made from the video signal.

An information processing apparatus may control display of a GUI image including indexes that allow a user to select the entirety or part of an image content piece. The information processing apparatus may include a controller configured to control display of a first GUI image including an index of each of at least one image content piece, and to control a display of a second GUI image including face thumbnail images, which serve as indexes that allow the user to select the entirety or part of an image content piece corresponding to an index selected from the first GUI image by the user, the face thumbnail images corresponding to faces detected from the entirety or part of the image content piece.

An information recording method and apparatus and an information reproducing method and apparatus in which AV data can be recorded or reproduced temporally continuously without producing fragmentation. To this end, the apparatus includes a storage unit 7 at least including a management information region and a user data region made up of plural logical blocks, and a recording unit 9 for continuously recording information signals from a recording start logical block to a recording end logical block in the user data region of the storage unit 7 and again recording information signals from the recording start logical block.
摘要:
Information processing equipment is so constructed that the power consumption of a disk drive for hard disks, optical disks, or the like can be reliably and sufficiently reduced. The host CPU (120) of an information processing unit (100) forms a command for changing the power consumption mode of a HDD (200) based on the state of control on the HDD (200). The host CPU supplies the command to the HDD (200) through a media controller (106). When the HDD (200) accepts the command, it changes its power consumption mode according to the instruction from the information processing unit. Thus, the information processing unit can control the power consumption mode of the HDD (200) based on the state of control on the HDD (200).

Rotary head recording and/or reproducing apparatus in which respective oblique tracks on a record medium are scanned, each track having an information signal area in which information data is recorded and a track following area in which a tracking control pilot signal is recorded. The track following area precedes the information signal area; and in the preferred embodiment, an additional track following area follows the information signal area. The pilot signal is recorded in only a portion of the track following area, the remainder of which has timing sync data recorded therein. In an after-recording mode the timing sync data is reproduced, detected and used as a reference to define an after-record area.
摘要:
Digital data representing a compressed image is separated into priority data and normal data, and formatted so that the priority data is repeatedly recorded on a magnetic tape. The transmission rate of the digital data is compared with the recording rate on the magnetic tape to control the number of repetitions of the priority data.
摘要:
Video and audio data are recorded onto video and audio signal recording areas of a track of a record medium, these areas being included either in one of several segments in the track or the track being comprised of only a single segment of video and audio signal recording areas. Audio data that is supplied at substantially the same time as the video data is compressed and recorded in a first audio sector of the audio signal recording area. Then, depending upon whether a first or second audio signal recording mode is selected, either compressed audio data which is derived from the audio data supplied at substantially the same time as the video data or independent compressed audio data is provided. The derived or independent compressed audio data is recorded in a second audio sector of the audio signal recording area.
摘要:
Methods and apparatus are provided for recording and reproducing digital information signals including image and audio portions in successive tracks on a magnetic tape. An ID signal is produced for one of an image portion and an audio portion of a corresponding digital information signal to be recorded. The ID signal indicates whether the portion is to be after-recorded in a respective track. The ID signal is combined with the portion to form a recording signal. Previously recorded digital information signals are reproduced from the track and an ID signal thereof is obtained. The recording of the portion in the track is controlled based on the reproduced ID signal.
