The MT5593UGIJ 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
C
audio decoder, a four-link LVDS transmitter, a mini-LVDS
transmitter, a V-by-one transmitter, an EPI transmitter, and an
NTSC/PAL/SECAM TV decoder with 3D comb
filter(NTSC/PAL).
The MT5593UGIJ enables consumer electronics
manufacturers to build high quality, low cost and feature-rich
DTV.
The MT5593UGIJ family supports Full-HD
MPEG1/2/4/H.264/VC1/RM/AVS/ and H.264/HEVC video
decoder standards, and JPEG. The MT5593UGIJ also
supports Media Tek MDDi 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
MT5593 family has built-in high resolution and high-quality
audio codec.

120Hz experience. It integrates high-quality Full-HD ME/MC
technology.
The MT5593UGIJ family supports ASTC,DVB-T and
DVB-C,DTMB 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
