In the digital era, we are getting closer and closer to us. Car readers have also emerged. At present, there are mainly MP3/MP4/MP5 card readers on the market. MP3 can only play audio files, which is equivalent to traditional CD players. MP4/MP5 has video output function, which is equivalent to traditional VCD/DVD player. MP5 can read most network video formats, such as RM/MP4/AVI, etc. MP4 can only read AVI (XVID) format. In the principle of playing, the card reader stores information through the flash chip and then plays it in decoding. The traditional CD/DVD is played by optical principle and reads the photoelectric information on the disc. On volume, capacity, stability, and umbrella storage. The chip is superior to the optical disc, especially in terms of dustproof and shockproof, and the advantage is very large, so the failure rate is much lower. There are a lot of free resources available on the network, you don’t need to repeat investment when you use it, you can “rejoice the old” and change the content at any time.
