Embodiment

[0020] Such as figure 1 As shown, a live satellite program records a copyright protection system, including an RF antenna, a first main chip CPU1, a second main chip CPU2, and a storage device, the RF antenna, by demodulator, demodulated TS stream after demodulation The results are respectively sent to the first main chip CPU1, respectively, decrypt, and the second main chip CPU 2 is sent to the USB output interface and stored in the storage device.

[0021] Specifically, 1 satellite input, demodulation, output 1 TS stream through Tuner and Demod, then perform TS branch, one way to send the first master chip CPU1 to decrypt decoding, 1 channel flow through the second main chip CPU2 Encryption Convert to the USB output interface to store the storage device.

[0022] Such as figure 2 As shown, the present embodiment also provides a live satellite program recording copyright protection method, including the following steps:

[0023] 1. Reading and Beidou Information encryption:

Abstract

The invention discloses a direct broadcast satellite program recording copyright protection system, which comprises an RF antenna, a first main chip, a second main chip and a storage device, and is characterized in that the RF antenna is used for demodulating satellite input signals through a demodulator to obtain TS streams, and then the TS streams are shunted and respectively sent to the first main chip for decryption and decoding; the USB output interface is converted into the USB output interface, and the USB output interface is stored in the storage device; the invention further discloses a direct broadcast satellite program recording copyright protection method. According to the invention, the program recorded by the local machine can only be played on the local machine, even if the storage device recording the program is taken to other playing devices or other direct broadcast satellite devices, the program cannot be played, and the copyright of the program recorded and played by the direct broadcast satellite platform is protected to the greatest extent.

Description

Technical field [0001] The present invention relates to the field of satellite equipment, in particular, a live satellite program recording copyright protection system and method. Background technique [0002] Live broadcast satellite public service is a public welfare project that has not been connected to cable television networks in my country and rural areas. It is a public welfare project that is launched by wireless and watching radio and television programs. The purpose is to promote the public services of urban and rural radio and television . Through the live satellite method, the remote satellite is available, free to listen to the TV broadcast show including CCTV, Central People's Broadcasting Station, China Education TV Station and Provincial Satellite TV and Provincial News Radio Program, which can fundamentally solve the rural especially the remote area. The masses receive the problem of radio and television programs. [0003] Improve the teaching level of remote mo...
