General Description
The MediaTek MT5365/66 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/mini-LVDS transmitter, and an NTSC/PAL/SECAM TV decoder
with a 3D comb filter (NTSC/PAL). The MT5365/66 enables consumer electronics manufactures to build high quality, low cost and feature-rich DTV.
World-Leading Audio/Video Technology: The MT5365/66 supports Full-HD MPEG1/2/4/DiviX/VC1/RM/H.264/AVS video decoder standards, and JPEG.
The MT5365/66 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 MT5365/66 family has built-in high resolution and high-quality audio codec.
Rich Features for High Value Products: The MT5365/66 family enables true singlechip experience. It integrates high-quality HDMI1.3 (partial HDMI1.4),
high speed VGA ADC, dual-channel LVDS, USB2.0 receiver, Ethernet, TCON and panel overdrive.
