Fig. 2 is the structural drawing embodiment illustrated in fig. 1 of the vehicle-mounted MP4 player according to band WIFI function of the present utility model.
Wherein, 1 is cigar lighter, and 2 is Master control chip, and 3 is remote pilot chip, and 4 is Infrared remote controller induction interface, and 5 is storage chip group, and 6 is wireless network, and 7 is USB interface, and 8 is display screen.
Embodiment
Below in conjunction with accompanying drawing be preferred embodiment described in further detail the utility model.
The utility model provides a kind of vehicle-mounted MP4 player with WIFI function, comprise cigar lighter electric supply installation, USB starts transmitting device, WIFI data transmission device, storage chip group, Master control chip, remote pilot chip, MP4 data compression device and display drive apparatus, this vehicle-mounted MP4 broadcasting with WIFI function is carried out equipment by cigar lighter electric supply installation and is powered, only this equipment directly need be inserted to the cigar lighter place of vehicle, after vehicle ignition, power automatically to this equipment, user only need start broadcasting or the stop button of equipment, the unlatching to equipment or hold function can be completed.
USB starts transmitting device can be completed and have the vehicle-mounted MP4 player of WIFI function and the connection of computer and info-communication function.This equipment is by using USB connection cable, connect this equipment in computer, and start this equipment, the function of exchange of computer data and device data can be completed, USB interface is directly connected with computer equipment by the USB3.0 high-speed communication interface of international standard, without the need to any driving, the transmission communication between data can be completed.
After data enter vehicle-mounted MP4 player via data line or wireless network mode, complete process to data message and memory function by Master control chip and storage chip group.Described storage chip group is connected with described Master control chip, and carries out digital independent and storage by described Master control chip.
In this enforcement, described storage chip group is solid state memory chip, can complete the autostore function of mass data.High-performance Master control chip cohort, can realize the functions such as the analysis to data message, process and control, user individual optimum configurations.
In the present embodiment, Master control chip also connects described display drive apparatus and MP4 compression set, and the compressibility of MP4 and fidelity are all higher, and MP4 file is executable file, inside embedded in player, and preserves web address and the copyright statement of original copyright owner.In addition, MP4 also uses a kind of special digital watermark technology, even if by FM/AM broadcast playback MP4 music, also can detect the source of music.。
This equipment is equipped with the touch-screen of high definition simultaneously, dummy keyboard can be recalled on screen by felt pen, click input network address, certainly such input mode ratio keyboard is more loaded down with trivial details possibly, described high definition touch-screen is also provided with broadcasting startup, time-out, advance, retrogressing, stopping, volume control and setting parameter button, connect master controller chip in this button, have master controller to control.Described setting parameter is set the parameter of WIFI data communication module.
In the present embodiment, described WIFI data transmission device has Signal reception and dispensing device, and is connected with wireless network, is directly connected into wireless public network by WIFI data transmission module, carry out network data to browse and downloading of task, the use of user greatly easily.
Described Master control chip connects remote pilot chip, and this remote pilot chip peripheral hardware controls button, and is configured with Infrared remote controller.Remote pilot chip mates telepilot concerning foreign affairs, and the use a teleswitch vehicle-mounted MP4 player that also can have WIFI function to this of user carries out operation and controls, and greatly facilitates the use of user.
The Master control chip of vehicle-mounted MP4 player also connects MP4 compression set, play for carrying out compression to data, MP4 data compressing module adopts MPEG4 data compression technique, and make Audio data compression rate higher, after sound-reducing, distortion rate is lower, also support audio frequency simultaneously, video, the function such as surf the web, and amusement function is enriched, be digital times amusement rising star, make a great stride forward than MP3.
This novel involved vehicle-mounted MP4 with WIFI function plays, change the transmission of existing Carrier MP 3 Player data single on the market and data compression pattern, the WIFI function of advanced person has directly been dissolved in in-vehicle player, user is broken away from, and single use USB data line carries out the single-mode of exchanges data, original Carrier MP 3 Player connects computer and all needs connecting line, connected mode traditional so has not caught up with the wireless epoch, by the MP4 in-vehicle player of built-in Wi-Fi module.Just can " unconstrained " exchanged with computer, such as upload the constraint wireless remote transmission that download file just can realize departing from data line completely.
Original MP3 data compression format is also upgraded to more advanced MP4 data compression technique by compressed format, and make Audio data compression rate higher, after sound-reducing, distortion rate is lower.Meanwhile, the deficiency that MP3 player is maximum, " only hears its sound, loses its people " exactly, although also there is many color screen Large Copacity MP3 in market, and, generally all rest on and see in the level of picture, cannot appreciate video file, this has to be one and regrets.And MP4 is just different, it can be seen by audibility, and amusement function is enriched, and is digital times amusement rising star, than having development prospect widely before MP3.
It should be noted that; any one and the combination in any thereof in above-described embodiment is comprised according to the vehicle-mounted MP4 player of band WIFI function of the present utility model; but embodiment recited above is only be described preferred implementation of the present utility model; not the utility model scope is limited; do not departing under the utility model designs spiritual prerequisite; the various distortion that the common engineering technical personnel in this area make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
