MediaTek’s 4K Smart TV chip – MT9638 is AI-powered and offers support for the latest connectivity and display technologies. Today 4K Smart TVs have become a norm. Enhancement on the chip-level will make these devices more smart and efficient. On these lines, MT9638 supports AI-enhancement technologies such as AI super resolution, AI picture quality and AI voice assistants, plus variable refresh rate (VRR) and MEMC (motion estimation and motion compensation) so graphics appear smoother.
Additionally, MediaTek’s TV chip technologies also come with custom APU that brings high-performance AI computing to smart TVs. With built-in AI picture quality technology, the chip enables real-time content and scene recognition, automatically adjusting color saturation, brightness, sharpness, dynamic motion compensation and smart noise reduction to improve overall image quality. MediaTek’s AI super resolution technology, combined with the company’s MEMC technology, intelligently upscales resolution through multi-frame blending to deliver clearer images at the smart TV’s native resolution.
In terms of connectivity, the chip supports the latest connectivity technologies including Wi-Fi 6 for fast, reliable connectivity and HDMI 2.1, which integrates support for VRR to match movies or console gaming frame-rates in order to avoid screen tearing. The MT9638 also supports applications powered by AI voice recognition and AI-enabled video calls, opening up new ways for consumers to interact with their smart TV and connect with their family and friends. These technologies are turning living rooms into true home entertainment centers, delivering new, immersive experiences in streaming, gaming and entertainment.
Other features to MT9638 are Arm Cortex-A55 CPU, Arm Mali-G52 GPU and dedicated MediaTek APU, up to 4K60 resolution support with a multimedia decoding engine for HEVC, VP9 and the latest AV1 content, HDR10+ display support, enabling full array backlight local dimming with >2000 zones, Premium Dolby Atmos and DTS Virtual X surround sound support, latest HDMI 2.1a and USB 3.0 interfaces, in addition to gigabit-class Wi-Fi 6 connectivity.
With up to four far-field microphones, the chip provides whole room coverage for voice assistants with ultra-low power consumption (0.5W) on standby and ultra-fast, one-second resume for wake-up words.
MediaTek has shipped more than two billion units of its TV chips globally, powering products from entry-level to the flagship with comprehensive solutions that meet global TV specifications.
