SummaryDVD One Board consists of: Loader part that reads and transmits audio and video data saved at Optic Discs (DVD, CD-DA,

7、 VCD, CD-R) to MPEG Decoder part; MPEG Decoder part, which, by decoding and encoding data received from the Loader, produces analog signals; and u-Com that controls the overall system including the loader and MPEG decoder.2. How Does it OperateInsert the power cord and then power transmitted to each

8、 IC, and the SET will be the STAND-BY status which requires the least power for input the front panel key, input the STAND BY/ON key, extinguished the LED. Once the Power On key is entered, u-Com recognizes it and initiates each chipset, performs sequential algorithms such as determining whether the

9、 disc is in or not, and if in, what type of disc is loaded. Through this process, it can read disc data before transmitting it to the MPEG Decoder. The MPEG Decoder will then decode and encode such data before generating the final analog audio and video signal outputs.DVD-MODULE Block DiagramCIRCUIT
