Description of Invention (ί) Background of the Invention The present invention relates to an image signal recording device and an image signal regeneration device. This invention also relates to a method of recording an image signal. It is easy for the image signal to have a correlation between the frames of the Burmese picture. In an image signal recording and reproducing device, it may enhance the signal-to-noise ratio (S / N ratio) of the reproduced image signal by the following signal processing. In particular, on a recording side, a recorded original image signal is processed using correlation between two consecutive signals, and the final image signal is recorded in a recording medium. The regenerating end reads the image signal from the recording medium, and processes the image signal in the opposite manner to the recording end to restore the original image signal. Generally speaking, an editing process replaces this recorded image signal with a new recorded image signal update, which has no correlation with the previous image signal. In addition, this editing process makes it difficult to enhance the signal-to-noise ratio (S / N ratio) of the reproduced image signal, which uses the correlation between two consecutive frames.

Invention description () 1 9 Receive this edited information signal 1 9b The information signal generator 19 receives the output signal 4a of the A / D converter 4. The information signal generator 19 retrieves the information signal from the A / D converter 4. In particular, the information signal generator 19 uses Use the specified level (for example, the maximum level of a horizontal synchronization signal) as a threshold to distinguish this information signal from other signals. This information signal generator 19 detects and corrects the information signal as described above. , This information signal includes data signals, and the third oblique word indicates this editing information. This information signal generator 19 responds to the information signal 19b showing the current editing status, and updates this editing information. In addition, this information signal produces The generator 19 updates the program ID information, time code information (―time code signal), modified signal information, and other items in the information signal. In this way, the information signal generator 19 updates the information signal to a new information signal. The information signal generator 19 includes an error correction signal generator, an added signal generator, and a modulator. The error correction signal generator generates an error correction code for the new time code signal and the new data signal ( An error correction signal), and add the error correction code to the new time code signal and new data. The error correction signal generator outputs the added result signal to the modulator. The added signal generator generates a header signal and A synchronizing signal and outputting the header signal and synchronizing signal to the converter. In the information signal generator 19, the error correction signal generator and the output signal of the added signal generator are received by the modulator , Which has two level value signals in the relative time domain "0" and Λ 1 "two levels -2 5-This paper scale is applicable to the Chinese National Standard (CN S) Α4 specification (210X297mm) binding line (please read the precautions on the back before filling in this page) A7 B7 printed by the employee consumer cooperative of the Central Bureau of Standards of the Ministry of Economy V. The description of the invention (/) changes. The modulator converts the received two-bit level signal into a three-bit level signal, and combines the received two-bit level signal. This conversion prevents the level of the related signal from exceeding the limit levels of limiters 26 and 27. It should be noted that this modulator uses a clock signal with a waveform as shown in part (A) of Figure 9. The six clock signal periods have a waveform as shown in part (B) of Equation 9 with respect to one bit of the received signal (the error correction signal generator or the output signal added to the signal generator). The level of the received signal can be changed between 20 IRE and 80 IRE, respectively, with respect to the logic state "〇" and "1". This receiver performs the following modulation processing. If the received signal is in the "quote" state, it was previously in the "1" state, that is, if the received signal changed from "1" to M0 ", the level of the resulting signal of the change changes to 50 IRE, 20 IRE, 20 IRE, 20 IRE, 20 IRE and 20 IRE, relative to the sampling instants of each 6 clock signal periods, as shown in part (C) of Figure 9 If the received signal is in the "1" state, it was previously in the "0" state, that is, if the received signal changes from "0" to "1", the level of the modulation result signal changes to 50 IRE, 80 IRE, 80 IRE, 80 IRE, 80 IRE and 80 IRE are relative to the sampling instant of each 6-hour clock signal period. As shown in part (C) of Figure 9. If the received signal is in the "1" state, it was previously in the "1" state, also. If the received multiple number is maintained between two bits; 1 ”, the bit criterion of the modulation result signal has not changed, it is 8 0 IRE, 80 IRE, 80IRE, 80 IRE, -2 6 _ This paper size Leisure Chinese National Standard (CNS) A4 Specification (210X297mm) ----------- · -------- IT ------ (Please read the precautions on the back before filling in this Page) A7 B7 du printing by employees of the Central Standards Bureau of the Ministry of Economic Affairs. 5. Description of the invention (for) 80 IRE and 80 IRE, relative to the sampling instant of each 6-value clock signal period. If the received signal is "0" state , Which was previously "〇" state, that is, if the received signal remains "0" between two bits. The criterion of the signal of this tuning result has not changed, it is 2 0 IRE. 2 0 IRE, 20 IRE, 20 IRE, 20 I RE and 20 I RE are relative to the sampling instant of 6 clock signal periods each. Therefore, an intermediate level of 50 I RE is inserted at the level of the received signal between 20 IRE and 80 IRE. Interpolation between the 50 I RE levels reduces the rate of change of the signal level of the modulation result, so that the level of the relevant output signal of this reinforced part 24 or 25 can prevent the limiter 26 or 27 from exceeding the limiter The level is shown in part (D) of Figure 9. The relative values of the three-level signal are 20 IRE, 50 IRE and 80 IRE. The converter outputs the modulated result signal to a switch (a multiplexer), which is in the information signal generator 19. The enhanced portions 24 and 25 increase the high-frequency signal component, and therefore immediately generate a higher surge level, relative to the display image portion at the time position, after a display image is gradually moved. The two-level value signal is converted into a three-level value signal. Since the modulator in the information signal generator 19 suppresses the surge level, the edge information is prevented from leaking, which may be due to the current signal level exceeding The limit level in limiter 26 or 27 is generated. The information signal signal generator 19 also includes a one-level reference signal generator, which generates a -2 7 with a preset normal reference level (50 I RE) _ This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) Gutter (please read the precautions on the back before filling in this page) A7 B7 Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V.

Description of the invention (3 ^ ), Relative to its low-frequency component, attenuates the high-frequency component of the regenerated PB signal 39a. The de-emphasis section 4 3 outputs the attenuation result PB signal and thus the de-emphasis section 4 7. This dereinforced part 42 has the opposite function of the reinforced part 13 of the recording end of the device. As described above, the de-emphasis section 42 receives the reproduced Y signals 38b and 39b. The de-emphasis section 42 rearranges the line relative periods of the regenerated Y signals 38b and 39b in a normal line sequence, and combines them into a complete Y signal. This de-emphasis portion 42 attenuates the high frequency components of the complete Y signal relative to the low frequency components in a vertical direction. The de-enhancement part 42 separates the complete Y signal of the subtraction result into a sub-Y signal, which is opposite to the even-numbered line, and a sub-Y signal, which is opposite to the odd-numbered line, to separate from the signal at the recording end of the device The same way for the signal separation of part 7. The sub-Y signal for the even-numbered line is output from the de-emphasis section 42 to the de-emphasis section 4 5, and the sub-Y signal for the odd-numbered line is output from the de-emphasis section 42 to the de-emphasis section 46. The de-reinforced parts 44, 45, 46 and 47 have the opposite function to the reinforced parts 8, 9, 10, 11 of the recording end of the device. As described above, the de-emphasis sections 44, 45, 46, and 47 respectively receive the PR signal, the first Y-signal, the second Y-signal, and the second PB-signal. During a normal operation mode, the de-emphasized parts 4, 4, 45, 46, and 47 along the time axis direction (a time base direction or a time axis direction) attenuate the high frequency of the current received signal relative to the low frequency component Composition, according to the previous received signal, relative to a number of previous frames -34- This paper standard is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) --------- L --- · --- order ------ ^ line (please read the notes on the back before filling in this page) A7 B7 printed by the employee consumer cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Invention description (3 >) (or picture field ). The de-strengthening parts 44, 45, 46, and 47 are supplemented by the enhancement result PR signal 44a, the enhancement result Y signal 45a, and the enhancement result γ signal 46a. The result of this enhancement is the PB signal 47 3. 〇 The de-enhanced parts 44, 45, 46 and 47 are received by the TCI discriminator 40 with the information signal 40a. This information signal 40a includes editing information, which indicates editing start, termination, and editing. The operation of the de-enhancement parts 44, 45, 46, and 47 is changed from the aforementioned normal mode to a special mode to indicate that an edit information signal corresponding to the start of an editing process responds. During this special mode of operation, the processing of the component image signals (the p R signal, the first sub-Y signal, the second sub-Y signal, and the second sub-PB signal), as well as the time at which the editing process occurs It is executed regardless of the component image signal before the time when the editing process occurs, and there are multiple frames (or fields). In other words, the current frame (current field) processing of the image signal according to the previous frame (previous field) component is interrupted when an editing process starts. Generally speaking, in the aforementioned operation-only mode, only a short time interval is held, and it is aborted when the relevant editing process has been completed.
