Description
Technical field
The utility model relates to a kind of vehicle-mounted digital television receiver.
Background technology
Improving constantly of Along with people's living standard, the user is also increasingly high to the requirement of television set, and DTV nowadays growth momentum is swift and violent, and also more and more widely with universal, therefore, the development potentiality of vehicle-mounted digital television can not be despised in the utilization of motor vehicle.Yet existing vehicle-mounted digital television receiver can only " foolproof " receiver, video input signal, and it is carried out video and audio decoder; Through processor decoded video input signals is broadcasted on display screen and loud speaker again; The video aspect ration is that 4:3 is exactly 4:3, is that 16:9 is exactly 16:9, and can not carrying out effectively, aspect ration switches; Like this in the process of broadcast items; If the screen of video file aspect ration and digital television receiver does not match, " stamp " phenomenon of cutting edge around will occurring, the vision that has influenced TV programme is ornamental.In addition, existing vehicle-mounted digital television receiver also has following defective: do not support multilingual switching, under the situation of needs, use inconvenient; There is not USB movable storage device interface, can not external movable storage device; Receiver only can be used for watching TV, function singleness, uninteresting; Do not support the picture and text output of OSD&VBI etc.
The utility model content
The purpose of the utility model is to solve the deficiency of existing vehicle-mounted digital television receiver; A kind of novel vehicle-mounted digital television receiver is provided; Overcome the conventional digital tv receiver and do not have width of cloth type handoff functionality; Be prone to " stamp " phenomenon of cutting edge around the TV programme, influence the vision sight of TV programme; Do not support multilingual switching, under the situation of needs, use inconvenient; There is not USB movable storage device interface, can not external movable storage device; Receiver only can be used for watching TV, function singleness, uninteresting; Do not support the shortcomings such as picture and text output of OSD&VBI.
The purpose of the utility model realizes through following technical scheme: a kind of vehicle-mounted digital television receiver; It comprises radiofrequency signal input interface, channel demodulation module, microprocessor, width of cloth type handover module, audio/video encoding/decoding module, display screen and loud speaker; The radiofrequency signal input interface is connected with the input terminal of microprocessor through the channel demodulation module; The audio/video encoding/decoding module is connected with the control terminal of microprocessor respectively with width of cloth type handover module, and loud speaker is connected with the lead-out terminal of microprocessor respectively with display screen.
The utility model also comprises a multilingual handover module, and multilingual handover module is connected with microprocessor.
The utility model also comprises a USB memory module, and the USB memory module is connected with microprocessor.
The utility model also comprises game module and OSD&VBI picture and text output module, and game module is connected with microprocessor respectively with OSD&VBI picture and text output module.
The beneficial effect of the utility model is: be provided with width of cloth type handover module, can change the aspect ration of input video file according to the screen size of receiver, avoid TV programme " stamp " phenomenon of side cut all around, guaranteed the sight of TV programme; Support multilingual switching, make things convenient for different language user's user demand; Be provided with USB movable storage device interface, can external movable storage device; Integrated various recreation no longer is uninteresting TV programme, has increased the interest that receiver uses; Simultaneously, also have the picture and text output of supporting OSD&VBI, stand-by power consumption is low and have characteristics such as output of PDIF DAB and sound accompaniment frequency modulation emission function.
Description of drawings
Fig. 1 is the utility model block diagram.
Embodiment
The technical scheme of the utility model is described in further detail: as shown in Figure 1 below in conjunction with accompanying drawing; A kind of vehicle-mounted digital television receiver; It comprises radiofrequency signal input interface, channel demodulation module, microprocessor, width of cloth type handover module, audio/video encoding/decoding module, display screen and loud speaker; The radiofrequency signal input interface is connected with the input terminal of microprocessor through the channel demodulation module; The audio/video encoding/decoding module is connected with the control terminal of microprocessor respectively with width of cloth type handover module, and loud speaker is connected with the lead-out terminal of microprocessor respectively with display screen.The vehicle-mounted digital television receiver also comprises a multilingual handover module, USB memory module, game module and an OSD&VBI picture and text output module, is connected with microprocessor respectively.
The vehicle-mounted digital television receiver also has following functional characteristics: adopt state compulsion standard DMB-TH; Removable and fixing reception TDS-OFDM modulation digital TV signal; Meet Moving Picture Experts Group-2; But 7MHz and 8MHz software setting; The AL/NTSC/SECAM standard is identification and pressure switching automatically; Can search for all frequencies of VHF and UHF; 8 favorite channel groups, can store nearly 4000 programs; Support EPG program guide Presentation Function, support father and mother's lock function; Output of PDIF DAB and sound accompaniment frequency modulation emission function possess 200 frequencies (0.1MHz stepping).
