Specifications are subject to change without notice
MediaTek MT1389
is a DVD player system-on-chip (SOC) which incorporates advanced features like high
quality TV encoder and state-of-art de-interlace processing. The MT1389 enables consumer electronics
manufacturers to build high quality, cost-effective DVD players, portable DVD players or any other home
entertainment audio/video devices.
Based on MediaTek’s world-leading DVD player SOC architecture, the MT1389 is the 3
rd
generation of the DVD
player SOC. It integrates the MediaTek 2
nd
generation front-end analog RF amplifier and the Servo/MPEG AV
decoder.
The progressive scan of the MT1389 utilized a proprietary advanced motion-adaptive de-interlace algorithm to
achieve the best movie/video playback. It can easily detect 3:2/2:2 pull down source and restore the correct
original pictures. It also supports a patent-pending edge-preserving algorithm to remove the saw-tooth effect.
