4. MICROCONTROLLER – MediaTek
4.1.Description
MT5820 (Main IC) (U1)
The MediaTek MT5820 family consists of a backend decoder and a TV controller and offers high integration
for advanced applications. It combines a transport de-multiplexer, a high definition video decoder, an audio
decoder, a dual-link LVDS transmitter, a mini-LVDS transmitter, an EPI transmitter and an
NTSC/PAL/SECAM TV decoder with a 3D comb filter (NTSC/PAL). The MT5820 enables consumer
electronics manufactures to build high quality, low cost and feature-rich DTV.
World-Leading Audio/Video
Technology: The MT5820 supports Full-HD MPEG1/2/4/h.264/DiviX/VC1/RM/AVS/VP6/VP8 (option) video
decoder standards, and JPEG. The MT5820 also supports MediaTek MDDiTM de-interlace solution can
reach very smooth picture quality for motions. A 3D comb filter added to the TV decoder recovers great
details for still pictures. The special color processing technology provides natural, deep colors and true
studio quality video. Also, the MT5820 family has built-in high resolution and high-quality audio codec.
Rich
Features for High Value Products: The MT5820 family enables true single-chip experience. It integrates
high-quality HDMI1.4a, high speed VGA ADC, LVDS, mini-LVDS, EPI, USB2.0 receiver, TCON (option),
panel overdrive (option).
WW Common Platform Capability: Reserved transport stream input is for
external demodulator for other countries or areas. TV maker can easily port the same UI to worldwide TV
models. Excellent adjacent and co-channel rejection capability grants customers never miss any wonderful
stream. Professional error-concealment provides stable, smooth and mosaic-free video quality.
