Problems solved by technology

[0003] In view of: On the one hand, although there are many types and functions of vehicle-mounted multimedia systems, how to integrate the current vehicle-mounted audio-visual entertainment, assisted driving, vehicle-mounted computer and other functions into a more powerful product has become an urgent problem. Manufacturers in the automotive industry are facing more and more challenges. Consumers always expect their cars to have the latest audio and multimedia systems, as well as smarter video assisted driving systems; on the other hand, due to the in-vehicle functional systems Diversification, including on-board computer systems, on-board media playback systems, on-board assisted driving systems, etc., users hope to quickly switch between various functional systems according to actual conditions, and maximize the multiplexing of the system, so as not to take up too much Space and the willingness to satisfy and protect one's own investment to the greatest extent, this requires that the vehicle multimedia system in the market should have multiple functions and be able to quickly switch between various functions
In short, the functions of the multimedia systems currently on the market are relatively single and cannot fully realize the above-mentioned functions. A similar method to solve the corresponding problems is to install multiple independent systems on the car to complete their respective functions.
However, the cost of installing multiple independent systems on the car is too high, and the interior environment of the car may not provide enough installation space and affect the aesthetics of the interior environment

Abstract

The invention relates to a multifunctional vehicle-mounted multimedia system and a realization method thereof. The multifunctional vehicle-mounted multimedia system comprises an FPGA (Field Programmable Gate Array) based multimedia system whole body, and the FPGA based multimedia system whole body comprises an FPGA chip, a memory chip, a decoding chip, a coding chip and the like, wherein the FPGAchip realizes a basic computer system, a video decoding module, an MEPG-2 (Moving Picture Expert Group-2) decompression module, a video coding module and the like. The operating principle of the system is as follos: three different frame cache address spaces are respectively used for storing processing data, DVD audio and video data and reverse video data, and the real-time on-line switching of three kinds of data is realized through one button so as to multiplex system resources. The multifunctional vehicle-mounted multimedia system integrates multifunctional devices, the mutual real-time switching among different data sources is realized, and the hardware of the system can be updated as time goes on so as to protect the investment of consumers. As an FPGA based multimedia system, the multifunctional vehicle-mounted multimedia system can not only be applied to automobiles, but also can be applied to industries related to video processing.

Description

technical field [0001] The invention relates to a vehicle-mounted multimedia system, in particular to a multi-functional vehicle-mounted multimedia system and its realization method.
