Description
Technical field
The utility model relates to a kind of simple two-way signal and receives descrambling kilocalorie receiver, particularly relates to a kind of simple two-way signal being applicable to broadcast television industry Set Top Box and receives descrambling kilocalorie receiver.
Background technology
Conventional digital TV kilocalorie receiver is primarily of tuner, kilocalorie descrambler, audio/video decoder, CPU, digital signal output modules, power module six part composition.Wherein kilocalorie descrambler, audio/video decoder, CPU are integrated in a chip indivisible.If when having one can not meet engineering demand in three, need to change whole chip solution, if without suitable chip solution time; could complete design.
In the process of networking, a Digital Television kilocalorie receiver can only receive the program of a frequency, and often increasing reception frequency then needs increase receiver, and the number of devices of needs is many, and cost is high, and difficulty of construction is large, and the maintenance cost of equipment is high.
Worldwide, due to application scenario and country's difference, digital television signal has the multiple types such as DVB-S, DVB-S2, DVB-C, DVB-T, DMB-T, ISDB-T.Coded system then have MPEG2, MPGE4, H.264, the Multi-encoding mode such as AVS, AVS+.Receive and the required corresponding receiver of above-mentioned signal of decoding.Need to receive multiple types, completing multiple decoding process then needs multiple devices.Which has limited the application scenario of receiver, add the purchase cost of user, too increase production cost and the difficulty of equipment manufacturers.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple two-way signal that can realize and receives and the kilocalorie receiver of descrambling.
The technical solution adopted in the utility model is as follows: a kind of simple two-way signal receives descrambling kilocalorie receiver, comprise power module, digital signal processing module, CPU administration module, kilocalorie descrambling module and audio/video decoding module, it is characterized in that, described kilocalorie descrambling module comprises two tuners and two-way TS one to one and flows signal descrambler; Described audio/video decoding module comprises two-way decoder and output interface one to one.
As preferably, described kilocalorie descrambling module is connected with digital signal processing module is detachable.
As preferably, described kilocalorie descrambling module and digital signal processing module card insert type removably connect.
As preferably, described kilocalorie descrambling module passes through I
2c control bus is separated connection with digital parallel data/address bus with digital signal processing module plug-in.
As preferably, described audio/video decoding module is connected with digital signal processing module is detachable.
As preferably, described audio/video decoding module and digital signal processing module card insert type removably connect.
As preferably, described audio/video decoding module passes through I
2c control bus is separated connection with digital parallel data/address bus with digital signal processing module plug-in.
As preferably, described card insert type connects for screw-type connection.
As preferably, described card insert type connects for plug-in connection.
Compared with prior art, the beneficial effects of the utility model are: achieve simple two-way signal and receive and the kilocalorie receiver of descrambling.Each kilocalorie descrambling module can receive descrambling two paths of signals, and each audio/video decoding module also can be decoded two paths of signals.Such receiver can receive the program of two frequency bins simultaneously, is equivalent to two traditional receivers.Kilocalorie descrambler, audio/video decoder and CPU are separated.Make the card insert type equipment that user freely can change module.User is no longer necessary for often kind of digital television signal, and often kind of coded system prepares an equipment, only needs to change corresponding module card.And equipment manufacturers also only need to manufacture suitable module card instead of complete machine.This enhances the flexibility of equipment greatly, has saved cost.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the utility model wherein embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Arbitrary feature disclosed in this specification (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Simple two-way signal as shown in Figure 1 receives descrambling kilocalorie receiver, comprise power module, digital signal processing module, CPU administration module, kilocalorie descrambling module and audio/video decoding module, described kilocalorie descrambling module comprises two tuners and two-way TS one to one and flows signal descrambler; Described audio/video decoding module comprises two-way decoder and output interface one to one.
Digital TV Receiving kilocalorie descrambling module: have two groups of RF inputs and ring outbound port, supports that various digital television radio-frequency signal standard inputs and goes out with ring, select for user.Achieve simple two-way signal to receive and the kilocalorie receiver of descrambling.Each kilocalorie descrambling module can receive descrambling two paths of signals, and each audio/video decoding module also can be decoded two paths of signals.Such receiver can receive the program of two frequency bins simultaneously, is equivalent to two traditional receivers.
Independent of the kilocalorie descrambling module of decoder, the digital television signal receiving multiple types by multiple kilocalorie descrambling module realization is converted into after parallel TS stream does further descrambling and exports the TS stream after deciphering.Audio/video decoding module, realizes the decoding output sound vision signal of the TS stream of the various coded system of high definition/SD, for television receiver.
In this specific embodiment, described kilocalorie descrambling module and audio/video decoding module are all detachable with digital signal processing module to be connected.Shell mechanical connection adopts card insert type to removably connect on the one hand; The opposing party, on circuit, all passes through I
