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.

The core of their video offerings includes HDMI matrix switchers, available in configurations up to 16×16. These units support HDMI 2.1, enabling 8K resolution for applications such as video walls and multi-viewers. The matrixes also feature both analog and digital audio de-embedding capabilities. For signal extension, the company provides point-to-point extenders using various technologies, including HDBaseT for distances up to 100 meters and fiber optics for up to 10 kilometers. These extenders support 8K at 60Hz and can transmit HDMI, USB 3.0, and DisplayPort signals.
For networked AV distribution, Shenzhen HD-CVTE manufactures AV over IP encoders and decoders. These devices operate on a one-gigabit network, connecting through a standard PoE switch to distribute signals in point-to-point, point-to-many, and many-to-point configurations within a building. The system is designed for local networks, with a typical distance limitation of 100 meters between nodes. The hardware includes HDMI inputs and outputs, along with network ports for connection to the switch infrastructure.
In the audio domain, the company focuses on the Dante protocol for audio over IP. They produce Dante converters and bridges, which translate analog audio into digital signals for network transmission. Available models include 2×2 and 4×4 channel bridges, with 16×16 versions also available and the capability for custom ODM projects like 32×32. They also offer Dante-enabled amplifiers and a device that extracts audio from an HDMI input and outputs it as a Dante network stream. This allows for integration of HDMI audio sources into professional Dante audio systems.
Beyond signal distribution, the product portfolio shown at Hong Kong Fairs April 2026 includes system control and consumer-oriented devices. A programmable touch panel control system is available in 4-inch, 6-inch, and 10-inch sizes for managing integrated AV systems, lights, and curtains in smart home or commercial environments. For simpler applications, they offer plug-and-play HDMI splitters, splitter-extenders that work over Cat cable up to 70 meters, and 4K 60Hz video wall controllers that can drive up to ten displays from a single source.
