A signal processor includes a buffer memory for storing the image signal for output as a main image signal; a point setting section for storing a position on a temporal axis of the main image signal as a registration point in response to a given capture command, the main image signal corresponding to the capture command; a playback control section for causing the buffer memory to output an image frame following the registration point in response to a given playback command; a video capture section for generating a registration image based on at least one image frame in a neighborhood of the registration point of the main image signal outputted from the buffer memory, and storing the registration image; and an image superimposing section for superimposing the registration image onto the main image signal for display in a signal screen to generate a composite image signal.

Signal processor

A signal processor includes a point setting part that sets a position of a main image signal, as a registration point. A playback control part causes output of an image frame from the registration point used as a starting point in response to a given playback instruction. A capture processing part generates a registration image based on the main image signal and stores the registration image, the at least one image frame being placed in a neighborhood of the registration point. A point recording part writes the registration point into a memory and writes the registration image corresponding to the recorded point into the memory. A point calling part reads out the recorded image and the recorded point in response to a given calling instruction. The point setting part sets the recorded point and the recorded image as the registration point and the registration image, respectively.

An information reproduction apparatus which can perform repetitive reproduction is provided. In the apparatus, information recorded in an information storage medium is read. The read information is decoded. The decoded information is stored in a predetermined region of a storage device. During reproduction, information is sequentially read out and outputted in order of precedence at the time of writing the decoded information while the decoded information is stored in the predetermined region. When a start position of repetitive reproduction is designated, a repetition reproduction range is set. The repetition reproduction range is a range that would include the decoded information to be reproduced at one repetition reproduction. The decoded information is maintained in the repetition reproduction range. When an instruction to start the repetitive reproduction is provided, the decoded information in the repetition reproduction range is outputted and the decoded information subsequent to the repetition reproduction range is acquired.

Information reproduction apparatus and information reproduction method

An information playback apparatus is provided, which can provide a sound which sounds natural by controlling an abrupt change in a tempo in the case of random access playback. When a cue point is registered, audio data which makes seamless playback possible is stored into a cue point memory, and further, the beat density of a playback sound being played when the cue point is registered is measured and stored. When the cue point is specified to start random access playback later, a ratio of the beat density (&#x3b1;&#xd7;DBPM) of a playback sound being played when the cue point is specified and the beat density (DBPMreg) stored in advance is found. Then, the random access playback is started after the beat density of a playback sound to be played after random access playback is started is corrected to be equal to the beat density when a start of the random access playback is specified.

Information playback apparatus

An information reproducing apparatus is provided, which has a new cue point setting function with excellent operability for enabling new application form. Specifically, a cue point for specifying a start position for playing back a disc, and additional information or disc identification information corresponding to the cue point are stored in a backup memory. The additional information or the disc identification information is associated with the cue point and shown on a display according to a proper operation of operation buttons and a turning member. When the operation buttons and the turning member are properly operated, a system controller edits and adds the additional information, or edits the disc identification information in the backup memory. When the operation buttons and the turning member are properly operated to enter retrieval information, information stored in the backup memory is compared and retrieved, and the retrieved information associated with a cue point is shown on the display.

Information reproducing apparatus having cue point setting function

An information reproduction apparatus which can perform repetitive reproduction is provided. In the apparatus, Information read from an information recording medium is decoded by the plurality of decoding devices. Then a source of an output of the information reproduction apparatus is switched among outputs of a plurality of the decoding devices. If a start position to start repetitive reproduction is designated, another decoding device except one decoding device whose output is currently switched as the source is controlled so as to be able to begin to decode the information on and after the start position. Then if a start instruction is provided, the source is switched from the output of the one decoding device to the output of the another device. Further, the another decoding device is controlled to decode the information on and after the start position, and the one decoding device is controlled to be able to begin to decode the information on and after the start position.
