Problems solved by technology

[0010] Although the above-mentioned existing TV card can cooperate with the motherboard of the computer to achieve the effect of playing TV; but because the receiving device 8 directly receives and transmits the required external video and audio signals, there is no external encryption and authorized decoding mechanism, so it cannot be used. Related channel signals (such as restricted channels) are controlled; moreover, because the receiving device 8 can only receive and transmit audio-visual signals, it cannot perform real-time storage, pre-recording and editing actions

Abstract

The invention relates to a pay television structure for a personal computer. The pay television structure comprises a signal receiving unit, a coordinator, a demodulator, a verification unit, an authorization unit and a transmission interface, wherein the signal receiving unit is used for receiving an video and audio signal; the coordinator is connected with the signal receiving unit and can modulate the video and audio signal; the demodulator is connected with the coordinator and can demodulate the modulated video and audio signal; the verification unit is connected with the demodulator, comprises an MPEG encoder and a card reader, can receive the demodulated video and audio signal for related decoding, and outputs the video and audio signal after acquiring authorization; the authorization unit is arranged in the card reader and can provide authorization data for the verification unit; and the transmission interface is connected with the verification unit and can transmit the decoded and authorized video and audio signal to the personal computer for playing. Therefore, through the matching between the verification unit and the authorization unit, the effects of the control, the real-time storage, the prerecording and the editing of a channel signal can be achieved.

Description

Technical field: [0001] The present invention relates to a pay TV structure for personal computers, especially a structure that can utilize the cooperation of a verification unit and an authorization unit to achieve control, real-time storage, pre-recording and editing of channel signals. Background technique: [0002] General existing digital TV signal receiving device 8, such as Figure 4 As shown, it is applied to computer 9, which includes: [0003] The first signal receiver 81 is used to receive the first TV signal (RF signal) and output the first demodulated signal accordingly; [0004] The second signal receiver 82 is used for receiving the second TV signal and outputting the second demodulated signal accordingly; [0005] The third signal receiver 83 is used for receiving the third TV signal and outputting the third demodulated signal accordingly; [0006] a multiplexer 84 (Multiplexer), configured to receive the first demodulated signal, the second demodulated sig...
