Description

Multi-media LCD TV system

Technical field

The present invention is relevant for multi-media LCD TV system, refer to especially a kind of can be to audio-visual video recording/video recording, and can play various audiovisual materials, connect network and have the multi-media LCD TV system of combined type card reader.

Background technology

At present, decline gradually along with the production cost of LCD, add characteristics such as the low and high-res of consumed power, make it to become the first-selection of family expenses high-res TV from now on, and there is data to represent, from now in the world main flow man TV university factory be LCD TV with main direction, it might become after the DVD, another hot product of the whole world.

LCD TV is different from traditional tv (CRT TV), it handles the transmitting and displaying image with digital form fully, this makes it more can be connected with the numerical digit media apparatus in the reality, yet, traditional television set design concept is that built-in TV harmony device (TV Tuner) is done the TV programme channel selection, design multiple audio-visual interface simultaneously, single with regard to the video input interface, just comprise that VIDEO (meets VCR, video camera), S-VIDEO (meets VCR, DVD player), YPbPr (connects DVD player, box on the HDTV machine, Set Up Box), D-SUB 15pin (meeting PC), DVI (digital video interface) etc. connect interface, it is a multitude of names, because these connect interface all is wired connection, therefore, the external equipment of LCD TV, its mode of connection certainly will be loaded down with trivial details, and be stacked each other on together, and if will be on this LCD screen display image, need video input signals digitlization again with simulation, through colored idle conversion, the interlacing scan commentaries on classics is lined by line scan again, and video format convergent-divergent (SCALER) output can video picture.

In other words, present LCD TV is a kind of multi-media display of supporting the pattern of the input of multiple external multimedia equipment, but can support multiple peripheral audio-visual devices institute pattern of the input actual being meant of this what is called " multimedia ", and the audio-visual picture data after it is handled shows, and do not have various audiovisual materials forms are not directly separated/function of encoding process, thereby can't play-over by multi-media display, so present LCD TV does not reach the multimedia function of a tractor serves several purposes.

Summary of the invention

Because aforesaid many disappearances, the inventor is through the permanent research and experiment of making great efforts, and development and Design goes out a kind of " multi-media LCD TV system " of the present invention finally, in the hope of by proposition of the present invention, can contribute to some extent society.

A purpose of the present invention is to provide a kind of multi-media LCD TV system, the mode of operation of this system is skipped and is play external multimedia equipment, and play-over the audiovisual materials that had, to improve the situation that multimedia equipment piles up in a large number, this system comprises a multimedia processing unit, one video/audio transducer (tuner), one image-decoding unit, one multitone is decoding unit frequently, at least one data transmission interface (as USB2.0 and card reader), one radio network device (Wi-Fi), one display unit, one source of sound output unit and at least one storage element (as hard disk drive) etc., wherein this multimedia processing unit links to each other with each assembly of this system, and can control these assemblies, make this multimedia processing unit can utilize this video/audio transducer, image-decoding unit and multitone be decoding unit frequently, carry out various audiovisual materials decodings, again by this display unit and this source of sound output unit, difference image output and source of sound, and can utilize data transmission unit and these storage element access/memory data, this memory document by this display unit and this source of sound output unit, carries out corresponding output respectively.

For ease of to the object, the technical characteristics and the effect of the present invention, do further understanding and understanding, for the embodiment conjunction with figs., be described in detail as follows now:
