Embodiment Construction

[0015] The following structural drawings and embodiments further illustrate the present invention.

[0016] like figure 1 , 2 , 3 shown.

[0017] Cancel the circuit and USB interface that control USB reading and writing in the readable and writable audio player, leaving only the corresponding pins of the main control chip, and make it a test point, such as figure 1 shown. In order to be able to write the content of the record during production, the circuit and USB interface that control USB reading and writing are made in a special production fixture, such as figure 2 shown. During production, the main board of the audio player is put into a special production fixture, so that the machine and the fixture are connected as a whole through the test point, and the machine and the fixture together form a complete readable and writable audio player, such as image 3 shown. There is a USB interface connected to the USB read-write circuit on the clamp, so that the contents of t...

Abstract

A copyright protecting method of digital disc audio playing device includes providing an audio playing device being not able to be fetched and being not able to be recorded and realizing copyright protection function by canceling USB interface as well as relevant control circuits on said audio playing device, enabling user to only play content stored already in device and not enabling user to copy and to record content stored in device for realizing copyright protection function with simple means.

Description

technical field [0001] The present invention relates to a digital turntable audio playback device, in particular to a digital turntable audio playback device with a copyright protection function, in particular to a copyright protection method and device for a digital turntable audio playback device. Background technique [0002] In order to issue new audio files (for example: song albums, folk art programs, conference content, etc.), the recording industry needs the audio files to be delivered to users through a carrier. With the development of science and technology, there are more and more carriers, and they are getting smaller and smaller. General carriers are divided into vinyl records, tapes, CD discs, and audio players that support digital audio formats such as MP3, WMA, and WAV. Moreover, what the record industry needs is a carrier that has copyright protection capabilities and cannot be copied by users. [0003] Although black bakelite records are basically impossi...
