Embodiment
For structure, characteristics and the effect that specifies the utility model, existing following preferred embodiment of act and conjunction with figs. explanation are as follows.
As shown in Figure 2; The satellite signals receiving system 20 of the tool addressing identification function that the utility model one preferred embodiment is provided is used for and a satellite antenna 10 of commonly using; And one satellite television receive the top box of digital machine 12 phase mutual connections that the user installed and establish, constitute a satellite signals receiving system 2.
As shown in Figure 3 again; Satellite signals receiving system 20 includes global satellite addressing system (GPS) treatment region 30, a satellite frequency reducing district 40, a control circuit district 50; And a fundamental frequency transmission range 60, also being provided with a radioshielding spare 70 that forms with metal partion (metp) between each district, radioshielding spare 70 electrically conducts to earthed voltage; With circuit noise phase mutual interference between each district of reduction, and the signal transmittance process of avoiding each to distinguish receives the interference of ambient noise.Below the circuit structures in global satellite addressing system (GPS) treatment region 30, satellite frequency reducing district 40, control circuit district 50 and fundamental frequency transmission range 60 each district are done further to describe:
Satellite frequency reducing district 40 has reception bugle (feed horn) 41, one frequency down circuit 42 and a satellite signals output group 43 that is electrically connected in regular turn; Receive the satellite signals that bugle 41 is used for receiving digital television; And generation has the frequency electromagnetic waves signal of particular polarization direction; Processing such as output are switched in amplification, frequency reducing, filtering, fixed frequency and integration through frequency down circuit 42, and the baseband signal of particular polarization direction and frequency range is arranged by 43 outputs of satellite signals output group then.
Fundamental frequency transmission range 60 is provided with a link group 62 and is used to be electrically connected top box of digital machine 12, and link group 62 is electrically connected the satellite signals output group 43 in satellite frequency reducing district 40 and the integration transmission ends group 511 of transmission control chip 51 with the transmission standard identical with above-mentioned baseband signal.In addition; Can receive high-quality satellite digital TV signal in order to make satellite television receive the user; The design specification of radioshielding spare 70 around the fundamental frequency transmission range 60 and between the control circuit district 50, the link group 62 that needs baseband signal is maintained fundamental frequency transmission range 60 and the signal strength of the GPS signal receiving terminal group 312 of GPS treatment region 30 are than greater than 80dB.
Comprehensive above-mentionedly know; And cooperate shown in Figure 4; When satellite television receives the user when indoor control starts top box of digital machine 12, the control command that top box of digital machine 12 is seen off and wherein the direct voltage of folded band receive through the integration transmission ends group 511 of link group 62 by transmission control chip 51.Behind the direct voltage that power regulator 52 induction transmission control chips 51 are obtained; Be the required dc operation voltage of GPS chip 32 then with this voltage transitions; Therefore start GPS reception antenna 31 and see and return the GPS signal off accomplishing satellite positioning functions, and carry out addressing and numeric security is handled to produce address date by GPS chip 32.After transmission control chip 51 converts the address date of GPS chip 32 output into address signal, then can export link group 62 to by integrating transmission ends group 511.When top box of digital machine 12 starts; The reception bugle 41 of satellite signals receiving system 20 receives the satellite signals that the satellite TV system dealer is provided; When satellite TV channel that user's control figure STB 12 is selected to want to receive; 42 selected television channels of corresponding control command of frequency down circuit are treated to baseband signal with satellite signals, and are passed to link group 62.Therefore after link group 62 receives the baseband signal that frequency down circuit 42 are produced, the mixed top box of digital machine of promptly being exported with transmission control chip 51 12 that exports to of address signal.
Therefore when the satellite TV system dealer initially when client is set up satellite signals receiving system 2; In memory device 33 and top box of digital machine 12, store the program of coding, scrambler and encryption and corresponding decoding, descrambling and deciphering respectively, provide and set up the local corresponding authorized address of regional addressing then for top box of digital machine 12.When in case client terminal start-up receives satellite TV channel; Satellite antenna 11 is the satellite signals seen off of receiving system end just; The GPS reception antenna 31 of satellite signals receiving system 20 just receives the GPS signal; Through fundamental frequency transmission range 60 with the mixed top box of digital machine 12 that exports to of satellite frequency reducing district 40 handled baseband signal and control circuit district 50 handled address signals; By top box of digital machine 12 the address signal conversion process is gone out the corresponding regional address of GPS signal again, and make comparisons, if the corresponding regional address of GPS signal meets authorized address with the authorized address of top box of digital machine 12 stored; 12 output of top box of digital machine satellite TV system end is authorized the satellite television signal of playing, if do not meet then and can't play.
So; Even client is carried top box of digital machine 12 and is connected to another zone and the satellite signals receiving system 20 that the dealer of system sets up; Because this does not distinguish the program of pairing authorized address and the corresponding decoding of device for addressing that this district sets up, descrambling and deciphering to top box of digital machine 12, thereby can't receive the satellite television signal that this district provides.
The above; Be merely the preferable possible embodiments of the utility model, the disclosed in the aforementioned embodiment constituent components of the utility model is merely and illustrates; It is not the protection range that is used for limiting this case; The equivalent structure that all application the utility model specifications, claims and accompanying drawing are done changes, and the alternative or variation of other equivalent elements, all should be included in the scope of patent protection of the utility model.
