Embodiment 1

[0044] Such as figure 2As shown, the MPEG main control chip includes: an audio processing module, a video processing module, a picture processing module, a document processing module, an interface module; an audio processing module for processing audio files in MP3, WMA, WAV, ASF or AVI formats The video processing module is used to process video files in MPEG1, MPEG2, MPEG4, DIVX3, DIVX5 or XVID format; the image processing module is used to process pictures in JPEG and BMP formats; the document processing module is used to process documents in TXT format; interface module for supporting I 2 C bus, support USB-OTG function.

[0045] The MPEG main control chip is a processor based on DSP processing and ARM12 processing system. JPEG etc. The peripheral interface of the MPEG main control chip mainly includes memory interface, USB interface, memory card interface, camera interface, hard disk interface, display interface, network interface and so on. Support SDRAM, support DD...

Embodiment 2

[0048] Such as image 3 As shown, the digital TV receiving module is used to receive digital mobile TV signals of DVB-T, DMB-TH or ATSC; the digital TV receiving module includes: a radio frequency tuner and a demodulator; a radio frequency tuner is used for The received radio frequency signals of multiple bands are sent to the demodulator after low-noise amplification, frequency mixing, DC correction, low-pass filtering and gain amplification; the demodulator is used to convert the received zero-IF The signal, after channel demodulation and forward error correction, forms a TS stream in a standard format, and is used to send the TS stream to the MPEG main control chip for decoding and restoration, and then play a TV program through the display screen.

[0049] Because the digital TV receiving module of this system is composed of two parts, which are radio frequency tuner (RF Tuner front-end chip) and demodulator (Demodulator demodulation chip), such as image 3 As shown, RF T...

Embodiment 3

[0052] Such as Figure 4 As shown, the GPS antenna receiver is connected to the MPEG main control chip through a USB2.0 high-speed interface with OTG function; the GPS antenna receiver is used to receive GPS positioning longitude and latitude information of satellites.

[0053] The hard disk of this system is equipped with an electronic map, and the flash memory is equipped with an optimal routing algorithm. The GPS antenna receiver can receive the GPS positioning longitude and latitude information of five satellites, the error is not more than 10 meters, and then the software calculates the route and displays it on the 7-inch TFT LCD.

[0054] The system can track road information in real time. Wherever the car goes, the road map can calculate the information of the next intersection and guide the driver.

Abstract

The invention relates to the technical field of radio, in particular to a support for fixing vehicle-mounted multimedia equipment. The invention provides the support for fixing the vehicle-mounted multimedia equipment. The support comprises an intelligent multimedia system, wherein the intelligent multimedia system comprises an MPEG (Moving Pictures Experts Group) master control chip, a digital television receiving module, a GPS (Global Position System) antenna receiver, an extension interface, a display screen and a touch screen; and the digital television receiving module, the GPS antenna receiver, the extension interface, the display screen and the touch screen are respectively connected with the MPEG master control chip. Therefore, the bracket disclosed by the invention can provide an infortainment system with functions of supporting audio / video playing, picture browsing, text reading, sharing with contents of an IPOD, digital television receiving, GPS navigation and the like, so that the life of people in a vehicle is enriched.

Description

technical field [0001] The invention relates to the field of radio technology, in particular to a bracket for fixing vehicle-mounted multimedia equipment. Background technique [0002] Vehicle-mounted systems refer to products that can be used in automobiles or other motor vehicles, and are convenient for use in motor sports. The most common ones are vehicle-mounted MP3, MP4, GPS, DVD, vehicle-mounted power supply, and vehicle-mounted TV. The use of these vehicle-mounted products generally needs to be powered by the vehicle-mounted cigarette lighter. Vehicle-mounted products have penetrated into people's daily life and facilitated everyone's life. Cars have been used as people's daily means of transportation for 120 years. During this period, with the development of technology, cars have also undergone rapid changes. Vehicle system includes vehicle monitoring system, vehicle GPS system, 3G vehicle system, vehicle information system and so on. [0003] In-vehicle infotainme...
