Realtek demos how to bring Matter interoperability to existing Android TV set-top boxes: add Thread via a small USB dongle, run a TV-side controller app, and a legacy STB starts behaving like a smart-home control point rather than only a video endpoint. The pitch is architectural, not just a gadget: Matter is the application layer, while transport can be Wi-Fi, Ethernet, or Thread, so OEMs can upgrade an installed base without redesigning the whole platform. https://www.realtek.com/

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

Technically, the key move is the Thread path. Thread is an IPv6 mesh over IEEE 802.15.4, and the dongle effectively supplies that radio plus the border-router role so the STB can speak to low-power endpoints. Realtek’s RTL8762G/RTL877xG family is positioned for multi-protocol designs (BLE 5.3, Thread/Matter, Zigbee, plus interfaces like USB 2.0 HS and Ethernet), which is the kind of plumbing you need when a TV box becomes a controller rather than a passive client device.
On the device side, they show a compact endpoint that pairs Matter support with a touch LCD UI on the RTL8772GWP, so an accessory can be both a physical control surface and a networked node. In the booth it just flips LEDs, but the same pattern maps to sensors, locks, and small appliances where you want local state, local interaction, and predictable control even when “cloud first” is not an option.
The tour then pivots into latency-sensitive peripherals: ultra-low-latency wireless audio for TWS earphones, and input devices (mouse, keyboard, joystick) targeting up to an 8K report rate, where 8,000 updates per second implies ~0.125 ms sampling granularity in the best case. Realtek’s ecosystem here is about end-to-end latency budgets across radio, USB scheduling, firmware, and host drivers, and the fast booth-walkthrough style echoes the interview pacing you also see around Web Summit Lisbon 2025.
There’s also a “doorbell camera to smartwatch” concept: a live stream moves over 2.4 GHz Wi-Fi to a server (cloud in production, local PC in the demo) and then to a wearable client, illustrating how Realtek platforms can span capture, transport, and playback. Across the demos, the consistent theme is providing silicon plus SDKs and reference stacks so partners can ship connected products without rebuilding every layer, on a busy show floor.
