Description of drawings
Fig. 1 is the structured flowchart of many output top box of digital machine of an embodiment.
Embodiment
As an example of floodlight example the utility model being exported top box of digital machine more below in conjunction with specific embodiment and accompanying drawing is described in further detail.
As shown in Figure 1, among the embodiment, a kind of many output top box of digital machines mainly comprise microcontroller circuit, CA intelligent card interface, commutation circuit and a plurality of receiving element.Each receiving element can connect two television sets.In the present embodiment, export top box of digital machine more and only comprise two receiving elements (the first receiving element and the second receiving element), corresponding, four television sets and four remote controllers can be connected altogether.
Microcontroller circuit links to each other with governor circuit in CA intelligent card interface, commutation circuit and the receiving element, also can link to each other with remote controller by wireless.Micro-control circuit is for receive control commands such as arranging, change platform from remote controller, control command control commutation circuit according to correspondence is switched, CA smart card in the control CA intelligent card interface be that corresponding channel is deciphered, or to the governor circuit sending controling instruction of the receiving element of correspondence.
Commutation circuit links to each other with the governor circuit of microcontroller circuit, CA intelligent card interface and a plurality of receiving elements.Commutation circuit receives switching command and switches annexation between CA intelligent card interface and two receiving elements according to this switching command from microcontroller circuit, thereby makes the CA smart card can be coupled receiving element mandate and deciphering.
Each receiving element includes tuner, governor circuit and memory.Memory comprises DDR memory and flash memory.Because a tuner can only receive a program on the frequency, and a common frequency has one or two program channel, so each receiving element can receive at most and play two different program channels.Therefore the quantity of broadcast program determines on the set-top box several receiving elements to be set as required, two covers (or three covers) receiving element for example is set just can receives simultaneously two (or three) four (or six) different TV programme above the frequency.
It is a plurality of channel program mandates that the utility model is provided with commutation circuit of a CA smart card collocation.Mandate is the life period interval to the CA smart card to set-top box, that is: when extracting the CA smart card, the signal picture can not stop immediately, is postponing moments later just can to point out the insertion smart card, and program is still play in continuation and do not stopped at once simultaneously.This time delay of utilizing the utility model just realizes that a CA smart card is a plurality of channel authorizations simultaneously.Utilize this time delay, as long as allow governor circuit again detect the CA smart card before will stopping broadcast, television set just can not stop broadcast program.Describe for convenient, defining this section time of delay is T), and make microcontroller circuit control commutation circuit less than the time t of T the CA smart card is switched to each channel program in turn as its mandate, so just realized an effect that the CA smart card is a plurality of program mandates.
Top box of digital machine employing WHDI(Wireless Home Digital Interface, i.e. the wireless family digital interface exported of the present utility model) technology realizes that top box of digital machine is to the HDMI high definition wireless transmission between the multiple TV set more.WHDI(Wireless Home Digital Interface, i.e. wireless family digital interface) set a new standard that wireless high-definition degree video connects, it provides a wireless connections mode high-quality, that nothing is compressed.The MIMO(Multiple-Input Multiple-Out-put that WHDI adopts, multiple-input and multiple-output) modulation system technology and OFDM(Orthogonal Frequency Division Multiplexing, OFDM) can realize the transfer rate up to 3Gbps.Be operated in 4.9GHz ~ 5.875GHz frequency range, 20MHz or 40MHz passage meet global 5GHz frequency spectrum regulation, and scope is within 30 meters, penetrable wall, and postpone less than 1 millisecond.The transmission of radio HDMI high-definition audio and video can be wirelessly connected to any high definition display device from any high definition source device of family, as: television set, projection, high definition player, game machine, video tape recorder, set-top box etc.The Anywhere appreciation high definition that the user can be stayed at home is large stretch of, can reduce worry and the expense of installing cables and set-top box simultaneously.
The remote controller of many output top box of digital machines of the present utility model uses the wifi Digiplex, thus realize the people before each video playback point (before the television set) to the control of set-top box length apart from wireless multifunctional.And because the inner multisystem frame design that adopts of set-top box, each wifi remote controller can independently carry out the operation of each video playback point (television set), does not interfere with each other impact.
Many output top box of digital machines of the present utility model have realized that in family or public place a set-top box exports a plurality of channel programs simultaneously, and operation control is independent of each other.When many output top box of digital machine is used for family, many output top box of digital machines can be placed on the parlor, a plurality of rooms TV can use the high resolution audio and video signal of this set-top box output jointly, and a wireless WIFI remote controller can be joined in each room, and many output top box of digital machine is independently changed platform, the operation that is independent of each other is set etc.Its advantage comprises:
1. saved and be the expense of every television set configuration machine top box;
2. saved the expense for each set-top box buying CA smart card, and the monthly rental collected of every card per month;
3. the HDMI high definition is utilized WHDI technology wireless transmission, has avoided the worry of the long distance wiring in house;
4. with the wifi Digiplex set-top box is operated, avoided the worry that long distance is arranged the infrared remote control line in the house.And Operational Figure Of Merit is high, can realize that the function of controlling is more.The most important thing is that with the wifi Digiplex set-top box being operated control in each room is that the independent operation of each output port of set-top box is controlled, the TV that connects for other output ports is independent of each other.
When many output top box of digital machine was used for management place, public place, when for example being used for the restaurant, set-top box can comprise five receiving elements, can play simultaneously 10 channel programs.At this moment, export top box of digital machine more and can be placed on the control room, each TV of ornaments uses the high resolution audio and video signal of this set-top box output jointly in the TV of each parlor and the hall.Its four advantages when comprising for family, also comprise two each and every one advantages:
4. convenient operation management is controlled the TV signal that just can manage in each parlor and the hall in the control room to a set-top box;
5. conveniently carry out advertisement promotion, top box of digital machine is with the multimedia decoding function, can be to the broadcast of decoding of the numerous forms on USB flash disk, hard disk, the network.Therefore businessman can utilize this system to carry out the advertisement broadcast, realizes the advertisement putting of wide scope.
Although description of the present utility model is carried out in conjunction with above specific embodiment,, those skilled in the art that can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all are such substitute, improve and change all is included in the spirit and scope of attached claim.
