The copyright owner has no objection to the copied part disclosed in this patent, for example, it can be displayed in the patent and commercial purse And other official files and records, but otherwise retain all copyright rights. Since the infringement of image copyrights has become increasingly rampant, methods for identifying image records or authorized sources of images have become more necessary. The source of the transmission capability or the recording (video) tape identification procedure has been known to those skilled in this art; however, the system has encountered a "congestion and re-entry technology that is easy to remove the source identification data ------ Question I. Known source identification or "Independence" can not transmit data during the activity of the video letter m. A form of video copyright infringement is to use a video camera to record in movies played in theaters. Images and sounds from the screen and speakers; this method may produce poor copy quality, but in some parts of the world, it is generally beautiful In addition, these copies are acceptable. In movie theaters, video projection projection systems are becoming more and more popular. Generally, these systems will incorporate a random form of images to protect the electronic image signal before the show, but once the signal has been Unscrambling numbers, source identification in the vertical scanning interval, and image random number technology cannot protect the projected image. We need a source identification method for movies and other materials to provide a source code to reduce the possibility of illegal copying, and If the copy has been made, the theater or source of the copy can be identified.

Description of the invention (method and device for retrieving the data reader called the unique mark reader. The data injection or "unique sassafras" procedure includes dynamically compensating the level of the image depletion pulse, κ carries information that can be read back from any video tape, and the video tape is recorded by the data injection unit in turn; in particular, The unique purlin carries the ID number and current date of the unit used. The compensation lasts for an entire half-scan interval and has a width of about 0.5 IRE units; a given half-scan interval has either a purported set value or a The setting value is 0.5 IRE units different from the sassafras value. The receiver detects the unique transcript data from the image signal and processes the data for display. From the data, the source of the image information can be determined, such as a video playback Specific theaters and dates. Another application is to include source data such as images being recorded. Brief Description of the Drawings: Figure 1 is a block diagram of a data insertion device; Figures 2a-2e show a series of waveforms representing synchronization characters; and Figure 3 is a block diagram of a unique Sassafras reader. The procedure of data injection or "adding a unique mark" includes dynamic compensation of the image elimination pulse level, which can be played from any video tape produced by the data injection unit or from a screen containing the signal of the data. Information read back from the video. In particular, the unique unit can carry the 1D number and current date of the unit that can be used. The above-mentioned monks continue for at least one complete half-scan interval and have a size of approximately 0.5 IRE units; a given half-scan area has a nominal setting value or a setting value different from the nominal value by 0.5 IRE.

Invention Instructions (3), provided by the image processor 14 The image signal 12 is given to the synchronous separator 16 and the H & V consumer 18; the unique marker data 20 is input into the data modulator 22, and the unique profile data 20 can be in a serial or parallel form. The unique purlin data format is a 64-bit block, the first 16-bit is a (data) frame synchronization character generated by the synchronization character generator 21; the second 16-bit is the source ID number; and the last 32 The bit is the date code. A typical synchronization character is shown in Figure 2a. The block can be repeated indefinitely. The signal format is binary Manchester: "0" is represented by 0-1 transition, and "1" is represented by 1-0 transition. The phase reference is provided by the sync characters shown in Figure 2b. Each data bit therefore occupies two half-scan intervals. As those skilled in the art understand, other data formats can be used, and the recovery procedure is It can be adjusted accordingly. The data modulator 22K receives the unique sync data 20 and the sync character data of the sync character generator 21 in a serial or parallel form, and generates formatted unique note data, which is accompanied by It consists of a 16-bit source ID number and a 16-bit synchronization character of a 32-bit data code; and I is that the (iv) is to be pulled into the image signal, so it is necessary to synchronize the data and the image signal The spreading of the sync separator 16 is composed of vertical scanning (semi-scanning interval> sync pulse 24, and the sync separator 16 is a technique that is understood by those familiar with the field of television engineering, and the vertical scanning is separated from the image signal Sync pulse 24. In addition, in addition to putting the data into the format applicable to the system, the data modulator 22 synchronizes the starting point of any formatted unique stream data with the half-scan interval rate using the vertical scan sync pulse 24 Because the individual bits of the data cover one or more half-scan intervals, it must be corrected during the horizontal and vertical erasure of the image signal (please read the precautions before filling this page ) -Binding line.

The output of the low-pass filter 44 is coupled to the 30 Hz notch filter 82; the 30 Hz notch filter 82 is used to remove the 30 Hz component, which can be used in the data due to the difference in the recording and playback image heads The frame-to-frame variation of the out-of-order order of the M video tape was observed in the; the 30 Hz notch filter 82 can be placed before or after the matched filter 52. The round output of the 30 Hz notch filter 82 is coupled to the analog-to-digital converter 46 (ADC). The analog-to-digital converter 46 also receives the clock signal 48 from the clock generator 50, and its clock frequency is about 4 KHz, but the clock frequency is from 1 KHz.

The output of the analog-to-digital converter 46 shown in FIG. 2b is coupled to the matched filter 52. The matched filter 52 makes the first estimate and doubles the amplitude of the data and greatly deletes the content of the above image. The matched filter The round of 52 is shown in Figure 2c. Due to the wrong time base in playback multiples, the excess of matched filter 52 may not always provide a sufficiently clear signal that can be used for further processing; in order to improve the usability of the outgoing signal of matched filter 52, the matched filter 52 It is coupled to the squarer 84, and then to the phase-locked loop 86 to generate a lock signal 88 in the data bit, the lock signal 88 is coupled to the storage register 56, M removed due to time base error The information changes. The round of matched filter 52 contains data with a deleted image, which is then associated with the sync character M to create a data frame; once the data is properly framed, it is digitally integrated to further improve the signal To noise ratio (SNR). This procedure includes writing the digitized values of 128 consecutive half-scan intervals to the storage register 56, which contains 128 valued registers that have been locked by the clock signal 57. The shift register 56, correlator 58, sync character generator 60, spike detector 62, and address controller 64 form a loop for synchronizing the data to make it easy for the user to read . The round-off of the storage register 56 is coupled to the association 58. In addition, a pre-planned synchronization character generator 60 couples a unique synchronization character 66 as shown in FIG. 2d to the association 58 so that The synchronization character information in the unique tick data 32 is associated with the synchronization character 66. As shown in Figure 2e, the associated data 68 is coupled to the peak detector 62; if it matches, then the next 128 half-scans of this paper are applied to the Chinese National Standard (CNS) Λ4 specification (210X297 mm): binding Line (please read the precautions on the back before filling in this page) 9 Printed by the Consumer Standardization Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs Α7 Β7 5. Invention description (6) The digitized value of the interval is added to the first 128 half-scanned intervals Digitize the value and continue this process as needed. During the accumulation process, the data value of each register will be directly multiplied by the number of times M is passed, and the image and noise will be averaged by M. After passing an appropriate number of times, which is generally more than 20, the regained 128-value high or low compensation half-scan interval sequence is coupled to the adder 72 and the 64-character register 76, where the data is decoded into a prototype 64 bits, and the appropriate data is read to the pavement terminal 80. The above devices can be implemented using hardware or a combination of hardware and software. The attached data is the source code information in Matlab language, which is used for the implementation of a part of the software of the unique reader. The read data can be connected to any display device that can read 64-bit data streams. This device can be an alphanumeric display, a computer screen, or a screen display that incorporates image signals; the display device can display ID numbers and Date code. In experiments using the above components, it has been found that the data can be restored to approximately 1/2 mV in a 1 volt image signal, less than 0.1 I RE. An important thing to note is that unless the synchronization characters in the insertion device and the reader are equal, there will be no round-off or misleading results; in order to make the reading device more universal The synchronous character generator in the reader has the ability to be manufactured by the user or pre-planned by the user. In principle, when using the above-mentioned system, a person who attempts to crack the system may simply blank out or use other methods to cause one or two distortions per 128 half-scan intervals. It may be short-lived and not enough.

Description of the invention (7) Importantly affect the effectiveness of the signal of copyright infringement. Since the data is periodic, this will distort one of these features; especially which feature is unknown, but with the current data format, there is a 25% chance of hitting those ID numbers. One, therefore pretending to be the identity of the infringed copyright unit; or, a copyright infringer may add a signal that overwhelms or invalidates the original unique purse, making the unique purse reader produce inconsistent or incorrect results. An alternative embodiment has some advantages; in a technique similar to that used for spread spectrum transmission, the basic data rate may be slow and "mutually exclusive or lotus" to a known pseudo-random sequence at the original frame rate ; In general, this pseudo-random sequence will be longer than the data sequence. The advantage is that it can maintain a high set change rate, K reduces the clarity of the data, and ensures that any person who attempts to cover up the special data will eliminate the double number. An unacceptable and long part. The second alternative method is that the M time-varying method simply exchanges the positions of data bits randomly within the block, so that there is no periodic distortion to meet any specific data characteristics of the M; this second method The method of data recovery is obviously more complicated, but it is still within the technical level. The third alternative is to encrypt the data before adding it to the signal and use complementary 05 decryption technology for M detection. The above device and method describe a system and method for adding a unique signal to the video signal. One of the main uses of the device and method is to prevent the infringement of the copyright and identify the source of the image data of the infringing copyright. Another example of this concept is to uniquely remember an original film, which was finally recorded in an image format, which can be borrowed from one of two methods. This paper standard is applicable to the Chinese National Standard (CNS) Λ4 specification (210Χ297 Mm) I— II: ——Subscribe to the IIIIII line (please read the notes on the back before filling in this page) 11 A7 __E__ printed by the Staff Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Invention description (8) completed. If the image is copied in the soft Η, the film has a short switching time bias light source to provide a small increase in the illumination of the film printer, the bias light source will be low enough to produce a brightness Very small change, but less than M was noticed by the viewer of the film. The second method is to provide such a polarized light source during the projection of the film. The polarized light rate is suitable for various projection media. When using a 50 Hz TV system, direct film projection at 24 frames per second and 25 frames per second is used. , Or when using 60 Hz TV system, adopt 3/2 structure. The above description is of an illustrative nature and is not intended to be limiting. Anyone who is familiar with this technique can clearly see more corrections based on the content disclosed on M. ---- ^ --- Γ --- ^ ------ 1T ------. ^ (Please read the precautions on the back before filling out this page) Industrial and Consumer Cooperation Co., Ltd., Central Bureau of Standards, Ministry of Economic Affairs The size of the printed paper is in accordance with the Chinese National Standard (CNS) Λ4 specification (210X: 297 mm) 12 5.300978 Description of the invention (9) A7 B7 element squaring number comparison 12.
