Description
Technical field
The invention belongs to the liquid crystal tv technology field, more particularly relate to the LCD TV of compatible multiple high definition demonstration and the design of DVD all-in-one.
Background technology
Along with starting broadcasting successively of domestic and international digital high-definition television program, can compatible multiple high definition show the indispensable function that has become present televisor gradually.Since LCD TV the sharpness of image, picture flicker free, do not have how much distortions several aspect considerably beyond common CRT TV, therefore be fit to very much be used for playing the program of high definition.Although many in the market LCD TV can compatible multiple high definition display mode, also do not have and compatible high definition to show, the product of built-in embedded DVD appearance again.Therefore, when the user need view and admire the DVD program, also need to use an external DVD player that signal is outputed to televisor, use very inconvenient.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, and a kind of compatibility LCD TV and DVD all-in-one that multiple high definition shows are provided.It embeds the DVD player core in the televisor and unites two into one, and the compatible multiple high-definition signal of energy, makes the user need not use external DVD player when viewing and admiring the DVD program, and is very convenient.
In order to achieve the above object, the present invention includes casing and be installed in circuit in the casing.The decoding digital video chip that circuit comprises tuner, be connected with tuner and sound accompaniment process chip, two electronic switches that are connected with the VGA signal of the high definition YUV signal of high definition terminal input and computing machine output, the Digital Image Processing chip, the LCDs that is connected with the Digital Image Processing chip and the backlight electric power thereof that are connected with the decoding digital video chip with electronic switch, the power amplifier that is connected successively with the sound accompaniment process chip and loudspeaker and to the power supply of above-mentioned circuit supply.Also embed a DVD player core in the casing, the audio signal output end of DVD player core is connected with the sound accompaniment process chip, the YUV signal output terminal of DVD player core via two electronic switch gatings wherein a road, be input to the Digital Image Processing chip then.
Tuner is a FI1216 type integral high frequency head, and the decoding digital video chip is the VPC3230D type, and electronic switch is the PI5V330 type, the Digital Image Processing chip is the GM1501 type, the sound accompaniment process chip is the MSP3450 type, and the DVD player core is the DSS813 type, and power amplifier is the TDA7266B type.
Radio television signal enters incorporate tuner through antenna, inside through tuning, mixing, in put, after detection, frequency discrimination handle, outputting video signal and sound carrier signal respectively.The brightness/chroma signal that meets vision signal, the input of S terminal of the composite video core of tuner output number and AV terminal input enters digital decoding chip VPC3230D, through its inner electronic switch gating wherein a road, the digital YUV signal of decoding back output ITR-B601 or ITR-B606 form is to GM1501.And then by GM1501 received digital YUV signal is carried out that interlacing is changeed line by line, the processing of image zoom, after the electronic switch gating of GM1501 inside, the output digital displaying signal drives liquid crystal display displays images.
The YUV signal of DVD output and the electronic switch gating formed via two PI5V330 by the VGA signal of the high definition YUV signal of high definition terminal input and computing machine output wherein a road, be input to GM1501 then, it is carried out in GM1501 inside mould/number conversion, interlacing become line by line, after the processing of image zoom, after the electronic switch gating of GM1501 inside, the output digital displaying signal drives liquid crystal display displays images.
The sound carrier frequency signal of tuner output carries out obtaining sound signal after the demodulation in MSP3450, the electronic switch of sound signal in MSP3450 of the sound signal of this signal and DVD output and the input of audio frequency terminal switches then, gating wherein a road carry out the processing of volume, high bass, balance after, output audio signal amplifies to power amplifier TDA7266B, drives loudspeaker then.
The plug-in SDRAM chip of GM1501 is a memory image signal when being used for GM1501 and carrying out the interlaced/progressive conversion.GM1501 inside is also integrated simultaneously CPU (microprocessor), and it passes through I
2C bus and I/O interface come the circuit of each several part is controlled.Plug-in FLASH is used to store the required program of machine run.When system started working, GM1501 read the program among the FLASH by data line among self the RAM and moves.
Among the DVD player core DSS813, not only comprise the servo circuit of control mechanical part running, also comprised the decoding circuit of MPEG2, can directly export YUV signal and sound signal.This movement also has independent CPUs in addition, can directly receive remote signal and control the DVD player core and realize various DVD functions, thereby alleviated greatly among the GM1501 the work load of integrated CPU.
The high definition terminal of this machine can be supported multiple high definition YUV signal such as 480i, 480p, 576i, 576p, 720p/60Hz, 720p/50Hz, 1080i/60Hz, 1080i/50Hz.
CD drive and insertion mouth thereof are vertical installation, are parallel to LCDs.Configuration aspects of the present invention adopts the DVD side, and the DVD CD inserts in the mode that is parallel to liquid crystal display from the side.Compare with common LCD TV, do not increase the thickness of complete machine because of built-in DVD.
Task of the present invention comes to this and finishes.
The present invention has designed LCD TV and the DVD all-in-one that the multiple high definition of a kind of compatibility shows, this all-in-one not only can be watched conventional television signal, but also can view and admire the high definition program of multiple form by the high definition terminal, this machine is also built-in in addition suction-type DVD, can play-over the DVD CD, the user uses more convenient.Because DVD player core and televisor core segment can shared one group of power-supply systems, become to say originally that also adding a DVD than a LCD TV more had superiority in addition from complete machine.It can be widely used in the places such as family, hotel.
