Description
Technical field
The utility model is relevant with satellite signal receiving apparatus, is meant a kind of signal receiving device of integrating many satellite-signal inputs especially.
Background technology
Universalness along with satellite television, satellite television receives the user when selecting to install, often can provide multichannel and height to receive the system dealer of image quality for considering, so big multisystem dealer all has satellite more than single on synchronous satellite orbit, the satellite-signal that can send out different carrier respectively satisfies the demand that user's multifrequency is selected of installing, yet the different satellites under each dealer of system can have different signal transmitting and receiving patterns because of the distributional difference of each satellite on track; Generally speaking, if each satellite under the dealer of system is adjacent one another are, and adjacent spacing only has within several longitude scopes, then the user can use " satellite signal receiving apparatus " patent in Taiwan Province's patent announcement M254030 number as this case utility model people, import satellite frequency demultipliers with two satellite-signals that single output receiving system constitutes, therefore the user only need set up single disc-shaped antenna to receive each satellite-signal, the reflection paraboloid of disc-shaped antenna reflexes to each satellite-signal respectively and respectively receives bugle (feed horn), therefore can collect low-noise amplifying frequency demultiplier (the Low Noise Block-downconvertor of each satellite-signal with the corresponding bugle that respectively receives of each satellite for the back level, LNB) make processing of circuit, have in regular turn comprise respectively receive bugle corresponding amplification and the frequency down circuit that connects, select to switch the matrix selector switch of various signal kinds and frequency range, the satellite signal carrier demodulation decided the frequency filter circuit, and the channel router of integration multichannel output circuit, so be that the entrained vision signal of exportable each satellite-signal is to client.
Yet, if being distributed with on track of each satellite under the dealer of system than big longitude difference, desire to make each satellite-signal to be sent to not only reception in full force and effect simultaneously on the single disc-shaped antenna, and limited size because of the reflection paraboloid focusing range of antenna, also make the bugle that respectively receives of corresponding each satellite-signal of collection on receiving, more belong to difficult, so the user just need set up the disc-shaped antenna corresponding to each satellite, arrange in pairs or groups respectively again as above-mentioned " satellite signal receiving apparatus ", and more need be respectively arranged with receiving box (the Set Top Box of corresponding demodulation at each " satellite signal receiving apparatus ", STB), therefore receiving the family need replace receiving box and could switch the entrained vision signal of each satellite-signal of reception, yet like this not only the need switched the demand that hardware just can be reached the selection of user's multifrequency with manual type, and the back level equipment of additionally setting up also increases almost many one times cost expenditure of installation user on foot.
Moreover, no matter which kind of form is the dealer's of system satellite distribution be, different system dealer's satellite reception quality and available satellite programming kind are inevitable different, but for making the user, the hardware that is provided with at previous selected system dealer is equipped with set specification mostly, thereby has limited the possibility of following replacing dealer of system or hardware resource change upgrading; Even if make the user the person of setting up for according to aforementioned single teledish kind of touching upon, when more having the satellite that increases wide-angle, later stage system end itself can provide the more video signal service of wideband, use side still must add extra back level equipment as the mode that the latter discussed, same increasing on foot installed almost many one times cost expenditure of user, the user causes if inapplicable situation is arranged when needing the replacing system that end is provided still more, also can only be chosen as the system dealer of similar script system end satellite form, optionally restriction is not only arranged too much, can face when upgrading equally such as the problem of above-mentioned cost waste in the future.
In view of this, this case utility model people does one's utmost to study can improve the dealer of system now and receive the shortcoming that the user is faced jointly on computer hardware, and desires to seek more effective and actual solution based on advantage that its previous utility model had.
