- the I frame is encoded (compressed within the frame) as another frame and is arranged periodically. Overnight with this I-frame, The P frame is ⁇ from the generalization of the I or P frame of the above.
- the size of each fi ⁇ shape represents the data size.
- the difficult signal subjected to the IB accommodation processing in the undesired BM PE Gffi decompression / expansion circuit 31 is supplied to the disk drive 12 and the disk drive 13.
- the hard disk device 12 is commanded by the reference device 34 so that the input transit signal is linked to the hard disk.
- the optical disc device 13 receives the signal from the signal supplied from the MP EGffi decompression / decompression circuit 31.
- the control device 34 instructs the control device 34 to invite only the signal of the I-frame to the disk. In this way, it is possible to make a movie on the hard disk and make an intermittent word on the disk.
- a self-recording control device 3 in the example of FIG. 3 can be used with a microcomputer.
- a flowchart in that case is shown in FIG. 5, and differences from the flowchart of FIG. 4 will be mainly described.
- Step 1 of FIG. 5 the timer 1 of the timer circuit 50 in the speech controller 34 is reset. Start up (Step 2) and proceed to Step 3. In step 3, the same frame waiting processing as described in FIG. 4 is performed, and the process proceeds to step 4.
- Step 4 checks the time signature of the first image, also as described in FIG.
- the function of the timer 1 is the same as the function described in the explanation of FIG. 4, and the image compression data supplied from the MPE GB decompression circuit 31 is intermittently supplied to the disk device 13 in FIG. Useful for recording.
- Step 14 If the time of door 1 has not passed as a result of the time lapse check (step 4) of the evening image 1 (operation of step 4, the image of one frame is stored only in the hard disk drive 12) (Step 15) If the time lapse of evening image 1 is between ⁇ and B # ( ⁇ in Step 4), go to Step 14 to determine whether the frame is an I frame. Check, as shown in Fig. 3, since a signal indicating whether or not the image compression signal output from the MP EGffi decompression / decompression device 31 is an I-frame is lined up in the word device 34.
- step 15 In which compressed data is written only to the hard disk of the hard disk device 12 without talking to the optical disk of the optical disk device 13. If the frame is an I frame (Y ⁇ J in step 14), the timer 1 is restarted (step 6), and the I frame ffi-compressed data is written on the optical disk of the optical disk device 13 (step 16). The compression of the hard disk of the hard disk drive 12 is also described (step 15). By repeating the process for each frame in this manner, the MPEG image data is recognized as a moving image on the hard disk and intermittently recorded on the disk.
- the interval of intermittent words can be determined by the timer 1 word.
- the MPEG is reduced in efficiency as shown in FIG.
- the image data of all I-frames is said to be intermittent in the 1 ) disk. If an integer multiple of this period is set between # and #; for example, if it is set to five times, the I-frame of the fifth frame will be used for the I-frame after playing a certain I-frame. become. Therefore, in step 4 of FIG. 5, if the interval between the words corresponding to the integer of the ⁇ time clock period of timer 1 has not reached ⁇ #, even if it is an I-frame, the Proceed to 15 and the I-frame will be recorded only on the hard disk.
- step 15 When the substituting force in step 15 is reduced, the process proceeds to step 8 for checking whether or not an alarm signal has been input as described in FIG. If an alarm signal is input ( ⁇ ⁇ J in step 8), the timer 2 of the timer circuit 50 in FIG. 3 is activated (step 10), and the process proceeds to step 11 for waiting for a frame.
- the space between the words of the timer 2 is half of the space between the words of the hard disk device 12 as well as the self.
- step 1 2 the age at which the ⁇ time of timer 2 has not reached
- the ability to speak long-term intermittent images on disk 3 is powerful.
- I-frame image data can be intermittently recorded on an optical disc.
- the data of the hard disk recorded with the moving image by the evening recording / reproducing apparatus shown in the embodiment of FIG. 1 is reproduced by the hard disk device 12 of FIG. 1, expanded by the JPE Gffi expansion / decompression circuit 11, When output from the circuit 10, the data is converted to a »signal that has not been compressed.
- the data of the intermittently written optical disk is reproduced by the f disk device 13 shown in FIG. 1, expanded by the JPEG expansion circuit 11 and output from the input / output circuit 10, and then decompressed. It is turned into an intermittent bell signal that does not meet like a movie.
- the data of the hard disk which was animated by the time-labs playback device shown in the difficult example in FIG. 3 was reproduced on the hard disk device 12 in FIG. 3 and expanded by the MPE Gffi compression / expansion circuit 31. Then, when output from the input / output circuit 10, the data is restored to a video signal that is not compressed.
- the intermittently recorded optical disk data is reproduced by the optical disk device 13 shown in FIG. 3, expanded by the MPE Gffi expansion circuit 31, and output from the input / output circuit 10. It is converted to an intermittent elephant signal that has not been performed.
- a JPE Gffi compression circuit is used instead of the JPEG fiber decompression circuit in the example shown in FIG.
- Each image data obtained by using the MPE Gffi compression / expansion circuit instead of the MPE Gffi compression / expansion circuit can be described as a moving image on the hard disk and intermittently described on the disk.
- the image data is intermittently written on the disk of the f-disk device, but the data is intermittently written on the video tape. It's gonna be g Available raw material
- image data is described as a moving image on a hard disk having high-speed access, and a trigger signal such as an alarm signal is intermittently described for a long time.
- a video corresponding to the wisteria portion of the trigger signal can be obtained in the state described on the hard disk together with the image intermittently written on the f disk.
- the device according to the present invention can significantly improve the utility value, particularly in the security field, as compared with the device in which a moving image is only stated after the input of the trigger signal.
