  1. 1. Anti-shock System on the Car DVD GPS Player by qualir - date:2011-11-19 Anti-shock System on the Car DVD GPS Player 2011-06-09 08:53:51 By qualir When the car move or fun fast, could the car dvd players work normally? Is there anything coulk keep it working? That’s why we need to learn the anti-shock system for the car dvd gps player. It includes electronic and mechanical anti-shock system. About the mechanical anti-shock system, it’s easy to understand. Almost all the car dvd gps unit has this system. It’s in the inside of the mechanism. When we are at home, we use the spring inside the mechanism to protect the laser working fine. This is different from dvd player. The anti-shock system is some kind of better construction, because the car dvd player working in a worse condition. As the protection of the spring, the laser could read the disk smoothly even the car is moving on the road. There is another electronics anti-shock system to protect the car dvd player. all of the disk need to be read by the laser and save on the memory of the car dvd player first. Then it plays from the memory to the player, which means what we could watch and hear from the car dvd player is not the real content at the same time as the player read. It always has 4 to 5 seconds delay. Do it could make the music and movie play normally, even the car is shocking. According from wiki: When the buffering circuitry is in operation, the compact disc is read at a fixed read speed or CAV and the content is buffered (with optional ADPCM compression) and fed to RAM within the player. The audio content is read from RAM, optionally decompressed, and then sent to the amplifier. When the disc reading is interrupted, the player momentarily reads the data stored in RAM while the tracking circuitry finds the passage prior to the interruption on the CD.
