CIRCUIT OPERATIONAL DESCRIPTION
DVD Module(DQL-1000Series)
1. Summary
DVD One Board consists of: Loader part that reads and transmits audio and video data saved at Optic Discs
(DVD, CD-DA, 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 Operate
Insert the power cord and then power transmitted to each IC, and the SET will be the STANDBY status which
requires the least power for input the front panel key, input the remocon 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 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.
