Abstract: Pictures are captured, and thereby moving-picture data is generated which represents a sequence of moving-picture fields. At least one picture is captured, and thereby still-picture data is generated which represents at least one still-picture frame corresponding in picture capture timing to one of the moving-picture fields represented by the moving-picture data. Components which correspond to said one of the moving-picture fields are removed from the still-picture data to generate supplementary still-picture information. Link information is generated which represents the picture capture timing correspondence between the still-picture frame and said one of the moving-picture fields. The moving-picture data, the supplementary still-picture information, and the link information are recorded on a recording medium.

Abstract: In a receiver operable in response to a data signal, an eye aperture size is detected along a time axis by an eye aperture detection circuit and is controlled by a control circuit so that it becomes a maximum. The eye aperture detection circuit determines different decision time points of the same level arranged along a time axis and judges whether or not an error is caused to occur at each of the decision time points, so as to detect the eye aperture size and to produce detection results. The control circuit processes the detection results in accordance with a predetermined algorithm to successively vary the eye aperture size and to keep the data signal at an optimum amplitude.

Abstract: A photo receiver branches a data signal obtained by photoelectric conversion and supplies the signal to a signal cutoff detector. Depending on the degree of an autocorrelation of a data signal obtained by an autocorrelation detector, the signal cutoff detector detects abnormality/normality. Depending on a level of a control signal to a VCO contained in a frequency phase-locked loop for use in clock generation, an out-of-synchronization detector makes determination of abnormality/normality. Outputs of both the detectors are ORed at an alarm processor and when at least one of the detectors detects abnormality, the detector generates an alarm.
