The Research of Vehicle Driving Multimedia Data Recording

The paper is the research and application conclusion of audio/video and sensor data recording in vehicle driving. The system encodes the data with MP4 format and reduces the data saving with dangerous signal detecting. With the data saved in SD card, this design can realize fully digital solider recording and obtain highly reliability in working. The article discusses the different working mode can be selected by drivers. With multimedia playback ability, we fully used digital chips and processor add-in functions. This recorder research, designed in combination with data recording and multimedia playing in vehicle has most multimedia application valuable in the future.
