Abstract

The present invention proposes an aging test method and device for vehicle-mounted multimedia equipment, wherein the method includes: setting a start mark and an end mark in the test multimedia information according to a preset marking strategy; controlling the test multimedia information to play from the start mark when the current When the multimedia information includes the end mark, end this playing of the test multimedia information; the control test multimedia information is played from the start mark to enter the next play of the test multimedia information until the sum of the playing time of the test multimedia information is greater than When it is equal to the preset test duration, the playback of the test multimedia information is stopped, so as to realize the aging test of the multimedia device. Therefore, based on the setting of the start mark and the end mark in the test multimedia information, the determination of the start and end time of the multimedia test information playback is realized at the software level, and the power amplifier component is not required to provide the play start and end time, which reduces the test cost.

Description

technical field [0001] The invention relates to the technical field of vehicle multimedia equipment testing, in particular to a method and device for aging testing of vehicle multimedia equipment. Background technique [0002] With the development of computer technology, the application of multimedia equipment in vehicles is becoming more and more extensive. Among them, in order to ensure the service quality of vehicle multimedia equipment, testing of multimedia equipment before leaving the factory has become a requirement, for example, aging testing of vehicle multimedia equipment. [0003] In related technologies, the aging test of multimedia equipment is to run an installation package to continuously play the test multimedia information for several hours. Since it is unrealistic to select a multimedia information that can be continuously played for several hours, loop playback is usually used. A section of test multimedia information is used to meet the aging test of mult...
