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.
1.Summary
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 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 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.
