Abstract
The invention relates to the technical field of communication, in particular to a self-adapting vehicle-mounted digital television receiver which comprises a signal receiving module, a demultiplexing module, a central processing unit, an aspect ratio switching module and an emitting device, wherein the central processing unit is connected with the signal receiving module, the demultiplexing module and the aspect ratio switching module; when the signal receiving module receives digital television signals, the central processing unit controls the demultiplexing module to start to conduct demultiplexing on the digital television signals and output the digital television signals to the aspect ratio switching module; the aspect ratio switching module adjusts the demultiplexed digital television signals; the emission device receives the digital television signals output by the demultiplexing module and then output the digital television signals. The self-adapting vehicle-mounted digital television receiver solves the technical problem of poor effect of digital television signals received by a vehicle-mounted system in the prior art, and further improves the effect of digital television signals received by the vehicle-mounted system.
Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of adaptive vehicle-mounted digital television receiver.
Background technology
Along with the development of science and technology, digital television application is in multiple occasion, existing bus is all provided with digital television, user's viewing can be supplied to easily, but, because the existing process to digital television signal is limited, for dissimilar, the player of different size, the effect of the television image played out can be affected.Such as, picture is too little, or picture to be widened etc. bad effect.
Therefore, there is the technical problem of the digital television signal weak effect received in onboard system in prior art.
Summary of the invention
The embodiment of the present invention is by providing a kind of adaptive vehicle-mounted digital television receiver, solve in prior art the technical problem that there is the digital television signal weak effect received in onboard system, and then achieve the effect that can improve the digital television signal received in onboard system.
The invention provides a kind of adaptive vehicle-mounted digital television receiver, comprise: signal receiving module, demultiplexing module, central processing unit, width type handover module, emitter, central processing unit connection signal receiver module, demultiplexing module, width type handover module, control demultiplexing module to open when signal receiving module receives digital television signal, demultiplexing is carried out to digital television signal and exports width type handover module to, by width type handover module, the digital television signal after demultiplexing is adjusted, emitter receives the digital television signal that width type handover module exports, and export.
Further, emitter is near radio transport module.
Further, also comprise memory module to switched by width type handover module data-signal store.
The one or more technical schemes provided in the embodiment of the present invention, at least have following technique effect or advantage:
Owing to adopting signalization receiver module in adaptive vehicle-mounted digital television receiver, demultiplexing module, central processing unit, width type handover module, emitter, central processing unit connection signal receiver module, demultiplexing module, width type handover module, control demultiplexing module to open when signal receiving module receives digital television signal, demultiplexing is carried out to digital television signal and exports width type handover module to, by width type handover module, the digital television signal after demultiplexing is adjusted, emitter receives the digital television signal that width type handover module exports, and export, solve in prior art the technical problem that there is the digital television signal weak effect received in onboard system, and then achieve the effect that can improve the digital television signal that onboard system receives.
Accompanying drawing explanation
Fig. 1 is the module diagram of adaptive vehicle-mounted digital television receiver in the embodiment of the present invention.
Embodiment
The embodiment of the present invention is by providing a kind of adaptive vehicle-mounted digital television receiver, solve in prior art the technical problem that there is the digital television signal weak effect received in onboard system, and then achieve the effect that can improve the digital television signal received in onboard system.
In order to solve in above-mentioned prior art the technical problem that there is the digital television signal weak effect received in onboard system, below in conjunction with Figure of description and concrete execution mode, technique scheme is described in detail.
The embodiment of the present invention provides a kind of adaptive vehicle-mounted digital television receiver, as shown in Figure 1, comprise: signal receiving module 101, demultiplexing module 102, central processing unit 103, width type handover module 104, emitter 105, central processing unit 103 connection signal receiver module 101, demultiplexing module 102, width type handover module 104, control demultiplexing module 102 to open when signal receiving module 101 receives digital television signal, demultiplexing is carried out to digital television signal and exports width type handover module 104 to, adjusted by the digital television signal after width type handover module 104 pairs of demultiplexings, emitter 105 receives the digital television signal that width type handover module 104 exports, and export.
In execution mode particularly, width type handover module 104 is according to the width type of the player of this vehicle-mounted digital television current, the width type received is adjusted to the width type of applicable current player, such as, the width type length-width ratio of the player of current vehicle-mounted digital television is 4:3, and being just adjusted to length-width ratio is 4:3.Just no longer be described in detail in embodiments of the present invention.
Before digital television signal being sent to width type handover module 104, by demultiplexing module 102, demultiplexing process is carried out to the digital television signal received, thus outputting audio data TS flows, video data TS flows, additional data TS flows.
When the digital television data stream exported by width type handover module 104 stores in a storage module, ensure that data can export glibly.
After whole by the digital television signal after width type handover module 104 pairs of demultiplexings, digital television signal after adjustment exports by emitter 105, particularly, this emitter 105 is near radio transport module, such as: bluetooth, or wireless WIFI etc., makes the user being positioned at bus clearly can hear the program that this video module device is play on respective seat.
Although describe the preferred embodiments of the present invention, those skilled in the art once obtain the basic creative concept of cicada, then can make other change and amendment to these embodiments.So claims are intended to be interpreted as comprising preferred embodiment and falling into all changes and the amendment of the scope of the invention.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
