Problems solved by technology
[0002] In the prior art, after receiving the received audio and video data, the device for recording and processing the received audio and video data has a high bit error rate, and the recorded data cannot be accurately transmitted to the server, and in the existing In the digital recording device, the surge circuit in the circuit can only reach 50V-60V, which cannot adapt to the large change of voltage in real life. In addition, the speed of the processor chip of the existing digital recording device is too slow to parallel Running multiple channels of audio and video information; at the same time, the existing digital recording devices cannot be connected to the operator's network and cannot transmit audio and video data in real time. Therefore, it is urgent for those skilled in the art to solve the above technical problems

Embodiment Construction
[0059] In the digital recording processing device for mass audio and video data, the method of distributing the database is as follows: figure 1 As shown, in step 1, after the mass data is received, it is transmitted to the data source server, and the data source server divides the mass data into N data file fragments, and each data file in the N data file fragments is divided into The slices are independent of each other, and the data source server separately distributes the data of each data file slice, distributes the data of each data file slice to the target node server, and sets the data distribution maximum in the N data file slices during distribution Optimize service bandwidth;
[0060] Step 2, after setting the data distribution optimization service bandwidth in the N data file fragments, the target node server divides each data file fragment in the N data file fragments into M data file fragments again, The data is divided into M data file fragments for data distri...
