MT5376
Ⅰ
. GENERAL DESCRIPTION
The MediaTek MT5376
family is 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 AC3 audio decoder, a dual-link LVDS transmitter, and an NTSC/PAL/SECAM
TV decoder with a 3D comb filter (NTSC/PAL). The MT5376 enables consumer electronics
manufactures to build high quality, low cost and feature-rich DTV.
World-Leading Audio/Video Technology : The MT5376 supports MPEG2 Full-HD video
decoder standards, and JPEG. The MT5376 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 MT5376 family has built-in
high resolution and high-quality audio codec.
