Abstract
The utility model discloses a set-top box condition receiving device, composed of a digital receiver module and an antenna module, wherein the digital receiver module comprises a card reader; the antenna module is provided with an antenna or an optical fiber or an amplifier for receiving satellite signals, cable signals and ground wave signals or the like. Compared with a traditional set-top box condition receiving device, the set-top box condition receiving device disclosed by the utility model is more reasonable in mounting structure, lower in production cost and more excellent in technology. Furthermore, the set-top box condition receiving device can receive satellite signals, cable signals and ground wave signals or the like through the antenna or the optical fiber or the amplifier, so as to achieve multiple manners of signal transmission.
Description
Technical field
The utility model relates to condition reception field, relates in particular to a kind of set-top box conditional receiving system.
Background technology
Along with popularizing of Digital Television, the Set Top Box products such as digital satellite television set-top box, digital cable box and digital terrestrial television Set Top Box have entered each family in a large number.Each operator is copyright protection and the differentiated service of carrying out different objects; in Digital Television, adopt conditional access technology; for meeting digital TV set-top box condition reception; existing product technology mainly adopts contact intelligent card formula; contact intelligent card mounting means is fixed, but the miniaturization, production debugging, the user that accept device product are used to the problem of all making troubles.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of set-top box conditional receiving system, comprise digital receiver module and antenna modules, in described digital receiver module, be provided with card reader.In described digital receiver module, be provided with channel decoding module, source coding module, power-supply system, described antenna modules, channel decoding module connect, source coding module connects successively; Power-supply system is all connected with source coding module with card reader.Described digital receiver module also comprises modulation output module, and described modulation output module is connected with source coding module.Described digital receiver module also comprises formatted file output module, and described formatted file output module is connected with source coding module.Described digital receiver module also comprises static memory and dynamic memory, is all connected with source coding module.Described card reader is card reader closely.Described antenna modules is provided with antenna and/or optical fiber and/or amplifier.In described antenna modules, be provided with cable, antenna and/or optical fiber and/or amplifier are connected with channel decoding module by cable.
?the utility model mainly carries out the utilization of overall improvement and Near Field Communication technology to the conditional receiving device of conventional set-top box, make set-top box conditional receiving system mounting structure more reasonable, and production cost is lower, and technology is more superior.And set-top box conditional receiving system can be by signals such as antenna or optical fiber or amplifier receiving satellite signal, wire signal and surface wave signals, can realize the signal transmission of various ways.
Accompanying drawing explanation
Fig. 1 is the utility model device schematic diagram.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
As shown in Figure 1, the utility model mainly comprises digital receiver module and antenna modules.Wherein, in figure, the little frame table in top shows antenna modules, lower frame representative digit receiver module.
Digital receiver module mainly comprise there is channel decoding module, source coding module, power system modules, modulation output module and formatted file output module, wherein channel decoding module, source coding module and formatted file output module communicate to connect successively; Power-supply system is connected with source coding module, and described power-supply system provides electric energy for digital receiver module and antenna modules; Modulation output module, formatted file output module and source coding communication connection.Different from traditional receiving system, digital receiver module internal of the present utility model is also provided with the card reader being connected with source coding module, preferably card reader closely.Smart card, without in insertion machine top box, only need to communicate to connect with card reader.When card reader is especially set closely, smart card, without being directly connected with card reader, can utilize close range communication techniques to communicate near only need to being placed in.
Described digital receiver module is also provided with static memory and dynamic memory, is all connected with source coding module, for the signal after stores processor.
Described antenna modules is provided with cable, antenna and/or optical fiber and/or amplifier.Set-top box conditional receiving system can be by signals such as antenna or optical fiber or amplifier receiving satellite signal, wire signal and surface wave signals.Described antenna and/or optical fiber and/or amplifier.By cable, be connected with channel decoding module.
Operation principle of the present utility model is:
Described antenna modules inside is electrically connected channel decoding module by cable, the signals such as antenna modules receiving satellite signal, wire signal and surface wave signal.The channel decoding module of digital receiver module internal and source coding module are exported by modulation output module and formatted file output module after successively signal being processed.Meanwhile, smart card by card reader or closely card reader and digital receiver module carry out wired or radio communication and be connected, realize the condition reception in Set Top Box.
Advantage of the present utility model is:
The utility model make smart card just do not need to be placed in Set Top Box body can by card reader or closely card reader communicate with digital receiver module, effectively solved that in prior art, contact intelligent card formula conditional receiving device causes to product miniaturization, produce debug, user's use brings inconvenient problem.
Antenna and/or optical fiber and/or amplifier are set in antenna modules, can, by signals such as antenna or optical fiber or amplifier receiving satellite signal, wire signal and surface wave signals, meet many-sided demand of client.
The utility model can be for products such as Set Top Box, TVs.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
