Description
The present invention relates to the controls playing technology of television receiver, the controls playing technology of the television receiver of particularly a kind of energy memory image and sound accompaniment.
Existing television receiver is the equipment that is used for receiving TV station or other media signal, at the picture that is used for noise elimination or start, generally be to use coloured background, dot character or figure realize, prior art also has HD image is used for noise elimination or start-up picture.At the picture that is used for noise elimination or start, if use coloured background, dot character or figure realize having only minority color electron gun in work, and long-term accumulation makes the ability drop of minority color electron gun, and colour cast appears in picture, and reduced the useful life of television set; If the employing high-definition image though improved the useful life of television set, has satisfied the visual needs of people, do not satisfy people's needs acoustically.
The controls playing technology that the purpose of this invention is to provide a kind of TV receiver set stored image and sound accompaniment, make television set at the picture that is used for noise elimination or start, the image that high definition is promptly arranged, play dulect music simultaneously, satisfy people visually, needs acoustically, also just make a simple passive television set, become and to deposit the active tv machine of broadcasting the picture-and-sound technology, make people want the image seen and want that the sound accompaniment of listening organically combines, make television for play lively, life-like, and can repeatedly change picture-and-sound according to user's needs; Electronics is deposited the picture-and-sound of broadcasting has increased the distinctive information of user, makes this television set strengthen anti-theft feature.
The object of the present invention is achieved like this: the controls playing technology of a kind of TV receiver set stored image and sound accompaniment, broadcast the execution of picture-and-sound circuit by depositing, and its execution in step is as follows:
The host CPU of a, television receiver remote control system is communicated by letter with coding chip PAL/NTSC by control line according to current state or according to the remote information that receives.
B, coding chip PAL/NTSC access image after overcompression and voice signal among the storage chip EPROM/FLASH, and decompress(ion) is reduced into digital video signal and digital audio and video signals in coding chip PAL/NTSC.
C, the encoded chip PAL/NTSC coding of digital video signal, again by low pass filter, the composite video signal CVBS of output simulation or Y/C separation signal are to display screen.
D, digital audio and video signals convert the audio signal of simulation to through audio frequency D/A modular converter, output to loud speaker.
Intermediate data in e, intermediate conversion chip DRAM storage decoding, the cataloged procedure.
F, clock generator are play picture-and-sound and are reached synchronous playing for decoding, coding provide a stable clock signal.
Carrying out television receiver of the present invention deposits the circuit of broadcasting picture-and-sound and contains remote controller, control line, loud speaker, display screen, low pass filter, coding chip, storage chip, intermediate conversion chip, audio frequency D/A modular converter.The picture-and-sound typing of storage chip EPROM/FLASH storage of the present invention is such:
The typing of a, image is input to needed image in the computer by recording devices such as scanner, digital camera, digital cameras, or with the image of various calculating functions identification, handle by image processing software, recompress into the mpeg format that decoder can be discerned, be stored at last in the EPROM/FLASH chip, as the signal source of broadcasting image.
The typing of b, sound: adopt all sound recording devices, voice signal is converted to the file that calculates function identification, or utilizing forms such as music file CDDA, WAV that active computer can discern, MP2, MP3, MPEG, the processing by the sound accompaniment process software makes it to become forms such as CDDA, WAV that decoder can discern, MP2.
C, synthetic: audio files and image spare after will compressing synthesize, and make it to become the sound accompaniment of image.
The present invention can realize by dual mode:
The IC-card working method:
Television receiver deposited broadcast the picture-and-sound circuit and be placed in the television set,, draw a storage chip EPROM/FLASH interface from circuit as the part of television receiver internal circuit; And the rom chip of store compressed picture-and-sound is made an IC-card, and be placed on outside the television receiver, link to each other with television set by storage chip EPROM/FLASH interface, can at any time IC-card be taken off according to user's needs, carry out repeatedly erasable.
External working method:
Playing circuit is external, to contain storage chip, coding chip, audio frequency D/A modular converter, intermediate transfer chip exactly and touch piece as one, be placed on the television receiver outside, as the external device that signal source is provided, vision signal and audio signal enter by the AV terminal of television receiver, the Y/C separation signal enters by the S terminal of television receiver, and the display screen of television receiver and loud speaker are as final video and audio frequency output.
Television set of the present invention is deposited the good effect that the technology of broadcasting picture-and-sound compares with prior art:
Television receiver of the present invention is deposited the technology of broadcasting picture-and-sound, and it not only can realize depositing under the signal broadcasting picture-and-sound having, and also can realize depositing broadcasting picture-and-sound under no signal.The image of energy display standard definition, high definition is play various sound accompaniments, and it comprises MPEGI and MPEGII data format.It is lively, life-like that the combination of picture-and-sound is play television receiver, and can repeatedly change picture-and-sound at any time according to user's needs.For example: can dispatch from the factory at television set and just store good required personage, scenery with hills and waters, flowers and trees, bird, beast, the graceful art work, honorable article, nationality amorous feedings image and dulect picture-and-sound information such as music, simultaneously also can be on-the-spot throughout the country design wed wonderful image, lucky image for the user, and the user is that wish, that pursue yearning, information such as picture-and-sound celebrating, that earnestly hope write television set, because the image of storage has increased the distinctive information of user, therefore, this television receiver also has anti-theft feature.
