only for LC-50LD266 )
General Description The MediaTek MT5561JUDT 1Gb & The MediaTek MT5561PUDT 2Gb family consists of a 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 mini-LVDS
transmitter, and an NTSC/PAL/SECAM TV decoder with a 3D comb filter (NTSC/PAL). The MT5561PUDT 2Gb enables
consumer electronics manufacturers to build high quality, low cost and feature-rich DTV.
World-Leading Audio/Video
Technology: The MediaTek MT5561JUDT 1Gb & The MT5561PUDT 2Gb support Full-HD MPEG1/2/4/h.264 / VC1/ AVS
video decoder standards, and JPEG. The MediaTek MT5561JUDT 1Gb & The MT5561PUDT 2Gb also support 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 MediaTek MT5561JUDT 1Gb & the MT5561PUDT 2Gb family has built-in high resolution
and high-quality audio codec.
