    MediaTek MT9666 is a mainstream 4K60 smart display SoC with integrated MEMC, a highly capable, 64-bit quad-core CPU, dedicated graphics engine and NPU that powers real-time image quality and super resolution enhancements.

    The MT9666 is ideal for a wide range of applications including smart homes, conference rooms, reception areas, advertising, educational settings, large-screen presentations, cinematic uses, and other home, business or commercial applications.

    MT9666

    Dedicated 4K75 Video Decoding Engine

    MT9669 enhances power-efficiency using hardware-assisted 4K video decoding of HEVC, VP9, and AV1 used by global streaming video services.

     

    Integrated Voice Assistant Support

    As an industry leader in voice assistant devices (VAD), MT9666 supports MediaTek AI-Voice technology powered by a dedicated, ultra-low power microcontroller with DSP connected to up to four far-field microphones. Low power standby and fast wake-up ensure that even when the smart display is in standby it can still be receptive to voice triggers. Brand manufacturers can integrate voice assistants into smart display devices to offer a convenient, hands-free interactive experience.

    AI Image Quality and Super Resolution

    The integrated NPU powers MediaTek’s advanced AI image quality technology (AI-PQ) and AI Super Resolution (AI-SR). AI-PQ is a real-time enhancement technology that recognizes faces and scenes in the video stream, automatically adjusting the color saturation, contrast, sharpness, and performing noise reduction. AI-SR technology performs intelligent, pixel-level upscaling of video streams to the display’s native resolution while also minimizing jaggy elements, ensuring a best-in-class 4K viewing experience.

     

    Integrated 4K60 MEMC

    The SoC includes 4K60 MEMC (motion compensation engine), allowing it to upgrade all content to match the native display speed.
