MediaTek has recently announced its new 4K smart TV chip, the MT9638, with an integrated high-performance AI processing unit (APU).

The latest MediaTek MT9638 4K Smart TV Chip supports cutting-edge 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. It sports high-performance processing for optimized visual quality, providing global TV makers premium features to design competitive 4K smart TVs.

“As smart home appliances become more intelligent and diversified, smart TVs are becoming the new hub for the smart home as consumers take advantage of AI-enabled multimedia features to control all their devices right from their TV,” said Alex Chen, General Manager of the TV Business Unit at MediaTek.” The new MT9638 continues our legacy as the No. 1 chip provider of smart TVs, bringing consumers incredible AI, multimedia, gaming, and entertainment experiences in theater-quality 4K.”


According to MediaTek, the company’s premium TV chip technologies are designed to heighten the user experience with our custom APU that brings high-performance AI computing to smart TVs. With built-in AI picture quality technology, the chip empowers 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 achieve clearer images at the smart TV’s native resolution.

Furthermore, the chip supports the latest connectivity technologies including Wi-Fi 6 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.

MediaTek’s MT9638 supports multiple advanced technologies, including a multi-core Arm Cortex-A55 CPU, Arm Mali-G52 GPU, and dedicated MediaTek APU. It has up to 4K60 resolution support with a multimedia decoding engine for HEVC, VP9, and the latest AV1 content. It also comes with HDR10+ display support, as well as Dolby Atmos and DTS Virtual X surround sound support. Lastly, with up to four far-field microphones, the chip gives whole room coverage for voice assistants with ultra-low power consumption (0.5W) on standby and a one-second resume for wake-up words.

The company has shipped more than two billion units of its TV chips globally, powering products from entry-level to the flagship. MediaTek MT9638-powered 4K smart TVs are expected to be available in the consumer market in Q2 2021.
