Description

A kind of analog telecommand playing circuit of the panel computer with PDVD

Technical field

The utility model relates to panel computer technical field, is specifically related to the analog telecommand playing circuit that a kind of touch screen with PDVD controls the broadcasting of its DVD video disc.

Background technology

Portable DV, for many friends liking travelling or often go on business, often wishes in tourism, also can watch excellent film, to eliminate loneliness during the journey.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.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, we know that panel computer is controlled by touch screen, when panel computer is increased DVD disc reader by us, then adopting touch screen to control DVD disc reader, is the technical task needing at present to solve.

Utility model content

In order to solve the problem, the utility model provides a kind of analog telecommand playing circuit that can be controlled the broadcasting of its DVD video disc with PDVD by touch screen.

Concrete technical scheme is as follows:

An analog telecommand playing circuit for panel computer with PDVD, analog telecommand playing circuit comprises main control chip, touch control IC, PDVD player and changes a yard chip, changes yard chip and adopts PHE8202KA; Main control chip adopts the micro-RK3128 chip of auspicious core, corresponding steering order is transferred back to RK3128 chip by I2C by touch control IC, then the GPIO0_D6 of RK3128 chip by the remote control code value modulating output of correspondence on the IR/GPIO101 pin of SPHE8202KA, thus the control realized SHHE8202KA, SHHE8202KA mimicked remote control signals defeated transmission PDVD player, control PDVD player plays.

Described RK3128 chip and PHE8202KA are provided with filtering circuit.

The beneficial effects of the utility model: the utility model is in the ultra-thin DVD player of the increase 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, the GPIO0_D6 of RK3128 chip by the remote control code value modulating output of correspondence on the IR/GPIO101 pin of SPHE8202KA, thus the control realized SHHE8202KA, SHHE8202KA mimicked remote control signals defeated transmission PDVD player, the broadcasting of control PDVD player.

Accompanying drawing explanation

Fig. 1 is governor circuit control flow chart of the present utility model;

Fig. 2 is circuit diagram 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.

See shown in Fig. 1-2, a kind of analog telecommand playing circuit of the panel computer with PDVD, analog telecommand playing circuit comprises main control chip, touch control IC, PDVD player and changes a yard chip, changes yard chip and adopts PHE8202KA; Main control chip adopts the micro-RK3128 chip of auspicious core, corresponding steering order is transferred back to RK3128 chip by I2C by touch control IC, then the GPIO0_D6 of RK3128 chip by the remote control code value modulating output of correspondence on the IR/GPIO101 pin of SPHE8202KA, thus the control realized SHHE8202KA, SHHE8202KA mimicked remote control signals defeated transmission PDVD player, control PDVD player plays.

Described RK3128 chip and PHE8202KA are provided with filtering circuit.

The utility model patent adds the related menu of DVD Play Control at main interface, after entering DVD broadcast interface, touch-screen clicks corresponding Control-Menu, corresponding steering order is transferred back to RK3128 chip by I2C by touch control IC, then the GPIO0_D6 of RK3128 chip is by the remote control code value modulating output of correspondence on the IR/GPIO101 pin of SPHE8202KA, thus realizes control to SHHE8202KA; The broadcasting of control PDVD player.

The utility model panel computer 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.

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.
