OVERVIEW
The MediaTek MSD6A638 family consists of a DTV front-end demodulator, a backend decoder and a TV controller and offers high
integration for advanced applications. It integrates a transport de-multiplexer, a high definition video decoder, an audio decoder, a two-link
LVDS transmitter, a V-by-One transmitter, and a NTSC/PAL/SECAM TV decoder with a 3D comb filter (NTSC/PAL). The MSD6A638
enables consumer electronics manufacturers to build high quality,
low cost and feature-rich DTV.
World-Leading Audio/Video Technology: The MSD6A638 supports Full-HD MPEG1/2/4/h.264/DiviX/VC1/RM/AVS/VP6/VP8 and
HD .264/AVC, 265/HEVC, VP9 video decoder standards, and JPEG. The MSD6A638 also supports MediaTek MDDiTM de-interlace
solution which 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 a natural, deep colors and true studio
quality video. Moreover, the MSD6A638 family has built-in high resolution and high-quality audio codec.
