Abstract: PROBLEM TO BE SOLVED: To provide a reproducing device and a reproduction method which perform special reproduction such as reverse reproduction, fast forward reproduction and fast rewind reproduction for not only a main picture but also a subs picture. SOLUTION: When reverse reproduction is performed, SYNCA information is acquired from, e.g. a navigation pack NV- PCK of a video object unit(VOBU) 3 and track jump is performed to a VOBU1 based on the SYNA information. Sub video data of an SP unit 2 is acquired from the VOBU1 and VOBU2, and main video data and sub video data of the VOBU3 are acquired. The video P35 of a main picture is decoded based on the main video data of the VOBU3, and also, a sub picture is decoded.

Abstract: PROBLEM TO BE SOLVED: To reduce jitters of a digital signal, such as a bi-phase digital voice signal which has been subjected to bi-phase mark modulation. SOLUTION: An input digital signal Da is delayed so that a signal DB for delay, a normal signal DN, and a signal DF for progress can be generated. Signal GB, GNd, and GFdd are generated from a jitter detection result, and the logical sum is generated as a signal Gor. In a period when jitter exceeding a prescribed ranged is absent, the logical product of the signal GNd and the signal DN is outputted as a signal DG, in a period when any jitter in a progressing direction is present, the logical sum of the signal GFdd and the signal DF is outputted as the signal DG, and in a period when any jitter for a delay direction is present, the logical product of the signal GB and the signal DB is outputted as the signal DG. The value of the signal DG at the rising edge of a clock CL, when the signal Gor is at high level is read, to generate an output digital signal Dc.

Abstract: PROBLEM TO BE SOLVED: To surely detect a commercial message included in a television broadcast.
SOLUTION: A chapter candidate point detection unit 45 detects a chapter candidate point as a candidate for a chapter point indicating reproduction start time or reproduction end time of a CM based upon at least one of a result of detection by a silent section detection unit 43, a result of detection by a scene change detection unit 41 and a result of detection by a black image detection unit 42. A chapter point determination unit 46 decides whether a television broadcast between chapter candidate points is a CM or a program based upon the chapter candidate points, and determines a chapter candidate point indicative of the reproduction time when one of the CM and program changes to the other among chapter candidate points as a chapter point. The present invention is applicable to, for example, a video recording device.

Abstract: PURPOSE:To eliminate an erroneous function by setting a new current consumption value lower than a set value in a system controller. CONSTITUTION:Upon depression of a program ON/OFF button 18 disposed on a machine body, a system controller 17 begins to observe current consumption value, stores a minimum current consumption value as a set value, and further stores a current consumption value lower than the set value as a new set value. When a current consumption value higher by an arbitrary amount than the set value is inputted, a decision is made that an external appliance 30 is turned ON and the external appliance 30 is not operated for any other current consumption value. Consequently, turn ON/OFF of power for the external appliance 30 can be decided and possibility of erroneous function can be eliminated because no set button is required.

Abstract: PURPOSE:To simply and surely execute the video recording by applying prescribed channel selection processing and control processing at the video recording of broadcast. CONSTITUTION:In depressing a video recording switch in switches 9A-9N, a sub-pattern is displayed regardless of whether or not the sub-pattern is displayed and a video signal Vj recorded on the VTR 40 is displayed on the sub- pattern, then an object picture is confirmed and video recording is simply and surely attained. In depressing a video recording switch, the signal Vj is made coincident with the signal Vi displayed on a master pattern with the relation of channel selection control signal CHN2=CHN1, since the signal Vj is recorded on the VTR 40, in depressing the video recording switch, the picture displayed on the master pattern is recorded without fail and the object channel is surely and simply recorded.

Abstract: PURPOSE:To allow a listener to recognize the reception state by displaying the carrier frequency as to all audio signals receptible at the present point of time. CONSTITUTION:After giving a frequency command signal AFRE corresponding to a presence discriminating frequency (f) of a carrier signal to a local oscillation circuit 13, a controller 3 fetches a tuning signal TUN from an IF count circuit 21 to discriminate whether or not a carrier signal component exists. As a result, when the affirmative result is obtained, a fluorescent display element corresponding to the frequency of the carrier signal component is lighted. Similarly, the presence of the carrier signal component is discriminated in the unit of 10kHz, and when the carrier signal component exists, the corresponding fluorescent display element is lighted.

Abstract: PROBLEM TO BE SOLVED: To obtain output pictures which are smooth in motion and look free of jaggies, after, by an easy method, converting input pictures of a certain frame frequency into output pictures of a higher frame frequency, such as in the conversion of interlaced pictures from 30 Hz frame frequency to field frequency of 60 Hz. SOLUTION: In this device, field pictures aF1 and aF2 are extracted from the input adjacent frame pictures F1 and F2 respectively and are composited to produce an output field picture A1. Supposing the composition is for an odd numbered line, a composite field picture B1 is obtained from an even numbered line in the same way. Thus, by repetition, composite field pictures sequence from odd and even numbered line sequence, A1, B1, A2, B2... are obtained. In this case, each line is read at the speed of 1/60 sec. and the composition ratios are made proportional to the reciprocal of the time difference between the output field pictures and the input frame pictures including extracted field pictures as 9:1, 5:5, 1:9, 7:3, 3:7 and so on.
