Description

A kind of governor circuit of the panel computer with PDVD

Technical field

The utility model relates to panel computer technical field, is specifically related to a kind of governor circuit that can realize the panel computer that DVD video disc is play with PDVD.

Background technology

In life, should be very familiar for DVD, but for many friends liking travelling or often go on business, often wish in tourism, also can watch excellent film, to eliminate loneliness during the journey.Can the image of high-quality why not since digital walkman can allow the music of high-quality become ubiquitous? so portable DVD player has also just arisen at the historic moment.Portable DVD player briefly, in fact be exactly one by DVD player miniaturization, and itself and a LCDs are combined, is furnished with audio frequency apparatus, powered by dc-battery, compact, the electronic product that can carry with easily, had portable DVD player, user just can enjoy the enjoyment of seeing a film anywhere or anytime.But portable DVD player function singleness, can only realize DVD and play.

Now, panel computer also receives the favor of consumer, its portable mobile, and its volume as notebook computer is small and light, can shift its field of employment at any time, have mobile dirigibility than desktop computer.It has digital ink and handwriting recognition input function, and powerful pen inputs identification, speech recognition, gesture identification ability, and has movability.Its expansion uses the mode of PC, can use " finger ", panel computer operates, make it simple as the use of paper and pen.Also support virtual or external keyboard and mouse, the operation as common computer simultaneously.Panel computer has abundant software resource, open platform, and function is very powerful, but existing panel computer commercially can not realize DVD to be play.Inconvenient consumer this at DVD playing back video disc at any time.

So, the basis of our panel computer adds a DVD reads dish decoding circuit, making it to become can with the new electronic product of DVD function, but DVD reads dish decoding circuit complex structure, if adopt DVD disc player to read its cost of dish decoding circuit high, circuit board size is large, can not meet the portable requirement of panel computer.

Utility model content

In order to solve the problem, the utility model provides a kind of governor circuit that can realize the panel computer that DVD video disc is play with PDVD.

Concrete technical scheme is as follows:

A kind of governor circuit of the panel computer with PDVD, governor circuit comprises main control chip, PDVD player and video decoding circuit, main control chip adopts the micro-RK3128 chip of auspicious core, video decoding circuit adopts ADV7180 chip, the CVBS signal that DVD player exports is converted to by ADV7180 chip the utilizing camera interface that CCIR656 signal is input to RK3128, realizes video decode and plays.

The governor circuit of a kind of panel computer with PDVD according to claim 1, it is characterized in that: described its 5-10 of ADV7180 chip, 15,16 is input pin, its 17 pin is provided with filtering circuit, it 27 to be connected main control chip and to realize controlling decoding with 28 pins, and decoding CCIR656 signal is input to the utilizing camera interface of RK3128,19 pins connect the CVBS signal that DVD player exports, and are connected in series a filtering circuit simultaneously.

The beneficial effects of the utility model: the utility model adds a ultra-thin DVD player on the basis of panel computer, and the video decoding chip ADV7180 chip reading dish is added at wiring board, make it to become the new electronic product realizing DVD function of playing discs, can at utmost reduce wiring board size and cost, meet the portable and multi-functional requirement of panel computer.

Accompanying drawing explanation

Fig. 1 is governor circuit module map of the present utility model;

Fig. 2 is the circuit diagram of video decode of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:

First the abbreviation that this patent relates to is explained:

MID is, than net book more portative a kind of terminal larger than smart mobile phone screen;

PDVD is (ProgressiveDVD): the DVD video disc player of " lining by line scan " is the regeneration product of existing common DVD.It avoid common DVD machine interlace signal and export the distortion or defect that cause, thus obtain the effect surpassing film image quality.

As shown in Figure 1, a kind of governor circuit of the panel computer with PDVD, governor circuit comprises main control chip, PDVD player and video decoding circuit, main control chip adopts the micro-RK3128 chip of auspicious core, video decoding circuit adopts ADV7180 chip, the CVBS signal that DVD player exports is converted to by ADV7180 chip the utilizing camera interface that CCIR656 signal is input to RK3128, realizes video decode and plays.

As shown in Figure 2, its 5-10 of ADV7180 chip, 15,16 is input pin, its 17 pin is provided with filtering circuit, it 27 to be connected main control chip and to realize controlling decoding with 28 pins, and decoding CCIR656 signal is input to the utilizing camera interface of RK3128,19 pins connect the CVBS signal that DVD player exports, and are connected in series a filtering circuit simultaneously.

The utility model governor circuit not only with panel computer function and also can compatible PDVD function, the front of its fuselage is capacitive touch screen, a row is provided with function button below, long by first button machine start, by after the switch opens of back being placement DVD/VCD laser disc place, an application of DVD function is selected after start, then laser disc is put into, after closing, machine just can identify laser disc content, so just can reach the function of portable DVD player, the operation of DVD part adopts capacitive touch screen operation.

In a word, the utility model adds a ultra-thin DVD player on the basis of panel computer, and the video decoding chip ADV7180 chip reading dish is added at wiring board, make it to become the new electronic product realizing DVD function of playing discs, can at utmost reduce wiring board size and cost, meet the portable and multi-functional requirement of panel computer.

Above content is in conjunction with concrete preferred implementation further detailed description of the utility model; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
