The MediaTek MT9638 is a high performance SoC designed for premium 4K60 HDR Smart TVs with MEMC capability. Designed for TV manufacturers create highly competitive products with global application, the MT9638 combines a high performance, multi-core CPU and APU (AI processing unit), wide memory bus, modern GPU, and a number of image and audio enhancement tools.

The integrated APU enables up to 10X faster processing times compared to external AI-chip solutions, at considerably lower power and with a reliability that avoids dropped frames, ensuring a high quality viewing experience.

Best for Cinematic Entertainment

The MT9638can decode 4K content (AV1, HEVC, VP9), supports Dolby Atmos and DTS Virtual X surround sound, global HDR standards and displays with up to 2304 backlight dimming zones, providing viewers best-in-class experiences for cinematic entertainment.

AI Super Resolution (AI-SR)

MediaTek’s unique AI-SR (super resolution), AI-PQ (picture quality) & AI-AQ (audio quality) technologies tap the flexibility and performance capability of the integrated APU. These intelligent enhancement technologies work together to automatically upscale and improve image and audio quality in real-time video, whether its live TV, online streams, or via disc-based media.

AI-SR and AI-PQ together optimize parameters such as sharpness and color based on content indicators, while also minimizing jaggy elements, performing noise reduction, and intelligent upscaling to the display’s native resolution. Combined with its MEMC capabilities, the MT9638 provides best-in-class 4K viewing experiences.

Voice Assistant Integration

As industry leaders in voice assistant platforms, MediaTek AI voice technologies allow brands to integrate voice assistants directly into their smart TVs, enabling users to directly control their TV or allowing other home IoT integration.

A dedicated sub-processor within the MT9638 can utilize up to four, far field microphones to enable an always-ready voice assistant with whole room coverage, ultra-low power (0.5W) standby and ultra-fast, one second resume on trigger word.
