The invention relates to a digital gateway and a television broadcasting control system. The digital gateway comprises a first tuner, a second tuner, a first demodulation chip, a second demodulation chip, a first audio / video decoder, a second audio / video decoder, a CVBS (Composite Video Blanking Synchronization) output port and an HDMI (High Definition Multimedia Interface) output port; the first tuner receives a first path of radio frequency signal and converts the first path of radio frequency signal into a first path of intermediate frequency signal, a first TS (Transport Stream) signal is output after the first path of intermediate frequency signal is demodulated by the first demodulation chip, a first audio / video signal is output after the first TS signal enters the first audio / video decoder, and the first audio / video signal is output to a first television by the HDMI output port; and the second tuner receives a second path of radio frequency signal and converts the second path of radio frequency signal into a second path of intermediate frequency signal, a second TS signal is output after the second path of intermediate frequency signal is demodulated by the second demodulation chip, a second audio / video signal is output after the second TS signal enters the second audio / video decoder, and the second audio / video signal is output to a second television by the CVBS output port.
Description
technical field [0001] The invention designs digital gateway technology, in particular relates to a digital gateway and a TV broadcast control system. Background technique [0002] With the progress of the overall conversion of cable digital TV, the number of digital TV users is increasing day by day. Many users have more than two TVs at home, and the relationship between digital set-top boxes and TVs is one-to-one, so when users handle digital TV services, they need to handle multiple terminals (digital set-top boxes + smart cards), so there is In case of double charges. [0003] Based on the multi-terminal situation of one household, radio and television operators have formulated preferential policies, for example: the charging standard for the first set-top box is 25 yuan / month, and the charging standard for the second set-top box is 10 yuan / month, thereby expanding the number of terminals. [0004] Some CA manufacturers have introduced the concept of mother-son card. T...
