Abstract

This invention provides a data record/playback device that retrieves stored data by specifying user-input data, and makes the retrieving easier. The data record/playback device, having: user input unit for receiving user input from a user; user input detector for detecting the user input through the user input unit; consecutive data input unit for receiving consecutive data including at least one of audio data and image data; consecutive data storage for storing consecutive data received by the consecutive data input unit; state detector for detecting a state that includes at least one of circumstantial information and eventual information about a moment when the user input detector detects the user input; association data storage for storing association data that includes the user input detected by the user input detector, the state detected by the state detector, and the storage position where the consecutive data is stored in association with each other; and display unit for displaying the user input detected by the user input detector and the state detected by the state detector in association with each other in accordance with the association data stored in the association storage.

Claims

1. A data record/playback device, comprising:

user input means for receiving user input from a user;

user input detection means for detecting the user input through said user input means;

consecutive data input means for receiving consecutive data including at least one of audio data and image data;

condition-matching interval detection means for detecting a condition-matching interval in the consecutive data that matches a prescribed requirement;

temporary storage means for temporarily storing the consecutive data received through said consecutive data input means in association with the condition-matching interval detected by said condition-matching interval detection means;

compression means for compressing the consecutively data stored in said temporary storage means so that a compressing state of the consecutive data ftom a specific interval is different from a compressing state of the consecutive data from other intervals, the specific interval being determined according to the user input detected by said user input detection means and the condition-matching interval detected by said condition-matching interval detection means;

consecutive data storage means for storing consecutive data compressed by said compression means;

association data storage means for storing association data that includes the user input detected by said user input detection means, the state detected by said state detection means, and storage position where the consecutive data is stored in association with each other; and

display means for displaying the user input detected by said user input detection means and the compression state of the consecutive data that is received by said consecutive data input means when the user input is received through said user input detection means in association with each other, in accordance with the association data stored in said association data storage means.

2. The data record/playback device as set forth in claim 1, further comprising:

playback specifying means for receiving user'"'"'s instruction to specify the user input; and

playback means for specifying a portion of the consecutive data stored in said consecutive data storage means according to the storage position stored in said association data storage means, and for playing back the specified portion corresponding to the user input data specified by said playback specifying means.

3. The data record/playback device as set forth in claim 1, wherein

said display means consecutively displays at least one user input following detection of the user input through said user input detection means;

and the display device further comprising;

specifying means for specifying one of the at least one user input; and

said display means displaying the state for the user input specified by said specifying means.

4. The data record/playback device as set forth in claim 3, further comprising:

editing means for editing the state displayed by said display means.

5. The data record/playback device as set forth in claim 4, wherein

said editing means detects a new user input overwriting the displayed state, and makes the displayed state clear for displaying the new user input.
