This invention provides a system for solving the problem of conditionally receiving separation of machine-card of digital TV and a method, in which, the system includes a HF digital tuner, a TS filter, a system controller, a CA decipher module, a descramble device and an Ethernet module. This invention also provides a method including: a user terminal transmits order packets, the system checks the use of the user then to pick up data related information needed by the user and decipher the information then to pack the deciphered data and transmit them to the user terminal, in which, the CA condition receiving module passes through the player connecting to the user terminal. |
