7.1. U401 (MT5561JUDT) & U401 (MT5561PUDT 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. Rich Features for High Value Products: The MediaTek MT5561JUDT 1Gb & The
MT5561PUDT 2Gb family enable true single-chip experience. It integrates high-quality HDMI1.4a, high speed VGA ADC,
two-link LVDS, , USB2.0 receiver, Ethernet MAC+PHY, single core CPU, and DVB-T/DVB-C demodulators . WW Common
Platform Capability: The MediaTek MT5561JUDT 1Gb & The MT5561PUDT 2Gb family supports, DVB-T, and DVB-C
demodulation functions. It reserves transport stream inputs for external demodulators for other countries or areas. TV maker
can easily port the same UI to worldwide TV models. First-class adjacent and co-channel rejection capability grants excellent
reception. Professional error-concealment provides stable, smooth and mosaic-free video quality
.
