5 · Detailed description The main feature of the present invention is to use digital format data, such as! + 'Or audio and video data, to discriminate whether the copy was stolen during normal playback and stolen copy to determine whether the copying was interrupted or destroyed. Robbery. Before the detailed technical content of the present invention is introduced, the MP3 music format and a simple example of the conventional technology are used to explain the composition of the MP3 memory card in the conventional technology and the process of reading when the music is playing. sound

The first figure shows the composition of an MP3 memory card in the conventional technology, in which an input / output interface 12, a decoding and control circuit 14 and a record ^ — 16 ′ are connected to each other. Memory 1 6 series stores digital music data, / output interface 12 2 accepts external readout instructions, decodes and controls electrical rain input 1 4 decodes and generates control signals to read music data from memory 16, most $ input / The output interface 12 outputs. < by

When the memory card is playing music normally, the waveforms of the internal circuit signals are as shown in the second figure. The enable signal (RE) generated by the decoding and control circuit i 4 is low (1 ow). When there are data items on the input / output interface 12 after the completion of the partial reading operation, it will stop for a period of time, and then continue to the next reading operation. When the memory card is copied, the waveforms of the internal circuit signals are different from those in the second picture. Please refer to the third picture. The read enable signal is continuous, and the input / output interface is continuous. There is data output, which means that the reading operation is continuous. This phenomenon is obviously different from the reading process when the memory card is playing music normally. The main reason is that the digital music data extracted during the music playback must be restored and the subsequent processing steps to be played. Therefore, its process is to read out. A piece of information will be stopped for a while, and iteratively repeated. The process of copying a memory card is only a matter of copying digital music data, and it does not need to go through processing procedures such as conversion or restoration. Therefore, its operation is performed continuously. For other sound, moving day, video, and audio and video data in digital format, the normal playback read action and theft action have the above-mentioned differences. Therefore, the present invention uses the digital format data to play and steal the data normally. The characteristics of the difference in the reading process between actions. A device to prevent digital format data from being stolen, as shown in the fourth figure, is used between the input / output interface 22 and the decoding and control circuit 24 and the memory 26. A monitoring circuit 25 is added to monitor whether the reading process is abnormal, and then decide to stop reading & Among them, as in the conventional technology, the decoding and control circuit 24 uses ^ to decode an externally input read instruction and generate a corresponding control signal.

In other embodiments, the decoding circuit may be omitted if it is not necessary to go through the decoding circuit. , Program 'Then, according to the present invention, the digital format data is prevented from being stolen. As shown in the fifth figure, it can also be referred to in conjunction with the fourth figure. In the NiuWan method system, a read command is input externally via the input / output interface 12. In the step, the control circuit 14 decodes and generates a control signal which is fetched and controlled by the memory 16. By detecting the readout instruction or control signal to judge the action of J should be learned, that is, step S12, it is judged whether the result of the external download is continuous reading or whether the action of copying is stolen. The item ‘order is that if a read command or control signal is detected for continuous reading, it is in the normal read operation mode, so the reading is changed to indicate step S13 and the data output is stopped, that is, step S15. Interruption, that is, jump to the next 1 result is $ ', then proceed to step 5 "calculation is possible, λ' production data, an extension step can be performed by a counter. Straightforward, such as in the monitoring circuit 25 according to the normal read f ^ The amount of data for the project is set in advance to read Erming = every action is to test whether the read action is stopped, or not. Before the step, the monitoring circuit 25 selects g 的 xi a *, action The number of broadcasts has not yet been calculated. * In the 4th step of accumulating the data read during the reading process, ΛΛ controls whether the calculation result exceeds the -critical value, that is, the maximum value of U is based on the efficiency when the stolen copy is stolen. The threshold reads. The amount of data read by the test will exceed the amount of data output by the Linmu Tian. If the cumulative amount exceeds the threshold, it means that this S15, β 屮 hanging American-style 'so it skips to step S13 and will continue The operation is interrupted and the data output is stopped. When page 8 of step si6

According to the knowledge, the reasonable working range is set first in the master mode to distinguish whether it is in the normal read mode. If it is found that the reading process does not meet the 1 machine a

Description of the invention (6) The result is yes, that is, the amount of data read out is the same as the foregoing, then the data amount of the readout data in this readout operation is within a reasonable range. Count to steps su ·, :: 丄: step S20. If the result is no, then skip If the data is read from the memory 26, and the data rotation is stopped. Then proceed to the data calculated in step S22: within the preset reasonable range, connect the working mode according to the normal reading; you can, for example, set a time in the monitoring circuit 25 when a stop is set in advance ^ 2, and the second read action The amount of time between readings, when reading is stopped, and j is often stolen. Efficiency-based tests indicate that the reading is not normal at this time. Normally, the reading is interrupted. In addition, the reading operation is interrupted to stop jm. The result of the raid was' will enter; whether this information is over. If you have n’t read the information agency], the breakout timer and the timer are reset to zero, that is, step S28, and the number of beams will be counted 丄 丨 a from the soil 丨 / and return to step S14. Skip to step 815 to stop the fruit from exporting data. The sub-circuit operates as early as 7L. In the foregoing process, the monitoring power is used in sequence and continued.] The data amount of the sold data and whether the reading interval is normal are used to determine whether to stop the digital r data in the data wheel in the normal reading mode.疋 Reasonable working range, according to the conditions of miscellaneous I π # un to raise sigh, we will read V.
