Problems solved by technology
However, when many users update songs or copy other files on the computer, it is easy to cause the loss of system files, making the system unable to work normally.
At the same time, system files are also easily leaked and decomposed
In addition, the USB storage device purchased by the user at will may also cause the system to malfunction due to matching problems.

Embodiment Construction
[0016] An encrypted TV singing and entertainment system of the present invention divides the storage area of the USB storage device into an encrypted area and a non-encrypted area, and uses the USB storage device system and the TV system to transmit encrypted authentication information to each other. If both parties confirm, Then the TV can read the encrypted data on the USB storage device, and the TV can start the software of the singing entertainment system to run; if the USB storage device has not been encrypted with the TV or computer, the data in the encrypted area of the USB storage device cannot Read, delete and other operations are performed to ensure the security of system files and song content.
[0017] see figure 1 As shown, an encrypted TV singing entertainment system includes a media player, a USB storage device connected to the media player to store files, a remote controller (IR) that provides a man-machine conversation channel, and a microphone (MIC) that ...

The invention discloses an encrypted method for a television singing entertainment system, comprising the steps: dividing a memory region of a USB memory apparatus into an encryption region and an unencryption region; arranging a constant characteristic value V for each USB memory apparatus, the television reading the characteristic value V of the USB memory apparatus through a USB peripheral management device and detecting whether the read characteristic value exists; if the read characteristic value exists, the television sending a nonzero random value Rh to the USB memory apparatus, the USB memory apparatus generating a nonzero random value Rd; the USB memory apparatus calculating and obtaining Fa according to a conventional algorithm F(Rh, Rd, V), sending the calculated result Fa and the random value Rd to the television; the television calculating and obtaining Fa1, Fa2, Fa3...according to the conventional algorithm F(Rh, Rd, V), Rh, Rd and all the preset V values (V1, V2, V3...); the television comparing the received Fa and all the calculated Fa1, Fa2, Fa3..., if there is equal value, the authentication passing, the television being capable of reading and identifying the content in the encrypted region. The invention can effectively protect the file in the USB memory apparatus and prevent the system file from losing.
Description
【Technical field】 [0001] The invention relates to the technical field of televisions, in particular to an encryption method for a television singing and entertainment system. 【Background technique】 [0002] With the development of the Internet and information technology, networking has become an inevitable trend of human life style and social and economic development. People are more and more accustomed to obtaining and browsing and enjoying online information such as streaming media from the Internet. And have produced the demand that these multimedia files (streaming media) are moved on TV set to watch. At the same time, in order to expand product differentiation, more and more TV manufacturers have launched TVs that can play various streaming media files such as music and video. On the hardware platform of the streaming media player, a set of singing entertainment system can be formed by adding a microphone preamplifier, an analog-to-digital conversion circuit (ADC) and...
