The HDMI interface is divided into four types: A, B, C, and D.
HDMI Type A connector is the most common type. Type A HDMI connector has 19 pins, a width of 13.9 mm, and a thickness of 4.45 mm. Devices that can be seen today, such as flat-panel TVs, 99% are HDMI connectors of this size.
HDMI Type B connector is very rare, and the transmission bandwidth is almost double that of Class A. If it appears to be excessively "overkill" in home use, it is now only used in some professional situations. With 29 pins and a width of 21 mm, it can transmit twice the amount of TMDS data in the HDMI A type.
HDMI Type C connector was born for small devices, and its size is 10.42x2.4 mm, which is nearly 1/3 smaller than the Type A, and the application range is small. There are a total of 19pin, which can be said to be a reduced version of the HDMI A type, but the definition of the pin has changed. Mainly used on portable devices.
HDMI Type D connector is the latest interface type, further reduced in size, with a double-row pin design, similar in size to the miniUSB interface, more suitable for portable and in-vehicle devices.

As mentioned earlier, the HDMI type A on the market is very common and highly versatile. However, in the wiring through the pipe, type A is relatively large due to the large size of the interface, and the pipe is inconvenient in operation, which may result in unreasonable wiring.
Starte precision Electronic Co., Ltd starts from the user experience, has a unique design, adopts a humanized design, and uses a adapter to complete the function of D to A. This problem of wearing the pipe wiring is easy to solve. The existing equipment does not have a type D interface. Still can continue to use.

This is the upcoming HDMI type D to A. The size of the type D HDMI interface is very small, compared to the previous type A HDMI interface, it can be called pocket. This compact interface connects the AOC to the engineering wiring. It is very convenient to connect the pipe to the type A adapter at the two ends. This allows you to connect devices that are only equipped with a type A interface. The whole operation is simple and convenient, because the type D is really very small and very small, so the operability and aesthetics of the engineering pipe wiring can be greatly improved.
Moreover, this new HDMI cable is perfectly compliant with the 2.0 specification and can achieve a transmission effect of 18G 4K@60 hz 4:4:4 with a transmission distance of up to 100m. The emergence of HDMI type D to A is the gospel of the engineering wiring scene and all the application scenarios that need to use the small interface AOC, and it is another proof of the innovation of Starte.
