    Dedicated 4K Video Decoding Engine

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

     

    Voice Assistant Technology & Smart Home Integration

    As an industry leader in voice assistant devices (VAD), the MT9669 can be equipped with up to four directional microphones to support directional AI voice technology. The MT9669 is capable of ultra-low power standby with fast keyword trigger and wake-up, allowing brand manufacturers to directly integrate voice assistants to allow intelligent and convenient hands-free interaction. Voice assistant capability not only offers users directly control over smart display devices, but also other inter-connected home IoT devices through spoken commands, creating a fully integrated smart home experience.

    Premium AI-Image Quality Technology Suite

    MediaTek AI-Picture Quality (AI-PQ) uses the integrated AI processing unit to perform real-time face and scene recognition to intelligently identify how to best optimize the video stream. Working in conjunction with MediaTek MiraVision image quality engine, it actively enhances the visuals in real-time by intelligently adjusting a wide range video stream factors, including color, brightness, contrast, sharpness, and dynamic range to deliver an incredible visual experience.

     

    AI-CV Support

    The high-performance NPU also enables AI vision support, which, combined with voice assistant services can provide facial recognition, scene recognition, face focus tracking, voice isolation, video background blurring, and more in a wide range of smart application scenarios giving brand manufacturers a great opportunity for unique, rich product experiences.
