Abstract: In a content shooting apparatus (Acc) for recording content data (Sav) containing video, audio, or data onto an information recording medium (214), in combination with first metadata (Di, Dm) containing a parameter representing scene information (SI), and allowing access to a specific portion of the content (Sav) with reference to the scene information (SI), a camera microcomputer (206) detects movement of a camera (101) to generate the first metadata (Di, Dm) by comparing the detected movement with a predetermined value (Th), and also generates second meta data (Di, Dm) by filtering out the first metadata (Di, Dm) generated within a predetermined specific window period (W) via a predetermined function.

Abstract: A content shooting apparatus is provided, in which thresholds for generating metadata concerning shot images can be calibrated in accordance with shooting conditions. In a content shooting apparatus (Acc) for converting content data (Dc) into a stream (AV) and recording the stream (AV) to a recording medium (214) in combination with content-related metadata (Dm), a camera (101) shoots a subject (105) and generates the content data (Dc), a camerawork statistics portion (206s) detects movement (?) of the camera, a camera microcomputer (206) compares the detected movement (?) with a predetermined value (Th) to generate the metadata (Dm), and an automatic threshold setting portion (206t) changes the predetermined value (Th) in accordance with the detected movement (?).

Abstract: In a magnetic reproduction system in which a magnetic tape must be controlled to run so as to keep a specified relative phase to a rotary phase of a rotary head, a tracking control apparatus obtains a characteristic curve showing a characteristic relationship between the relative phase and an envelope level of a reproduced information signal obtained by the rotary head by changing the relative phase, obtains a regression curve with respect to the characteristic curve, and controls the magnetic tape to run so that the relative phase becomes a value corresponding to a maximum value point of the regression curve.
