Description
Technical field
The present invention is a kind of optical digital disk Video Recorder, and particularly relevant for a kind of method for controlling number of revolution and the digital A/V optical disc camcorder of using this method for controlling number of revolution.
Background technology
See also Fig. 1, it is the built-in function block schematic diagram of the digital A/V optical disc camcorder (DVDrecorder) 10 of an instant imprinting formula, it is to receive multiple signal source (the conventional television signal receiver shown in the figure (TV tuner) 11 signals of being exported for example, with traditional video tape projector (VCR player) 12 and digital image and sound optical disk player (DVD player) the 13 simulation video-audio signals of being exported (Audio and Video Signal), or the digital audio-video signal exported of digital camera (DV) 14), the control circuits 16 in the digital A/V optical disc camcorder 10 receive these signals and are converted into the digital video-audio data (for example digital video-audio data of mpeg format) that meets specific format then.When inserting recordable CD 15 in the CD writer in the digital A/V optical disc camcorder 10 17, control circuit 16 can be according to user's operation, and the digital video-audio data imprinting that will meet specific format is to recordable CD 15.
See also Fig. 2 again, it is the built-in function block schematic diagram of another pattern digital A/V optical disc camcorder 100 of using always, wherein have more the numerical data storage device that a Winchester disk drive 101 is constituted, it is in order to the digital video-audio data that stores above-mentioned specific format (for example digital video-audio data of mpeg format), and then can offer the user and edit for the digital video-audio data of specific format stored in the Winchester disk drive 101, and then, see through CD writer 102 imprintings to recordable CD 15 with the digital video-audio data that editor finishes.For instance, the user can TV signal receiver (TV tuner) 11 is received TVs simulation video-audio signals be temporary in Winchester disk drive 101 be converted into the digital video-audio data of specific standard via control circuit 106 after, then after the user edit again through CD writer 102 imprintings to recordable CD 15.Or the digital audio-video conversion of signals of directly digital camera (DV) 14 being exported is to be temporary in the Winchester disk drive 101 behind the digital video-audio data of specific standard, edits through the user then, sees through CD writer 102 imprintings to recordable CD 15.Thus, the user just can be transcribed into the video-audio signal that is sent by the signal source in the Winchester disk drive 101, also can carry out actions such as digital video-audio data editor or CD burning simultaneously.In addition, CD writer 102 also can will be inserted the digital video-audio data unloading of specific format in the CD to this Winchester disk drive 101.
