Recently, the HDMI Licensing Company officially released the specification of the HDMI switch mode developed for USB Type-C. The birth of this mode allows HDMI-enabled source devices to be directly connected to a HDMI-enabled display using a USB Type-C connector, without cumbersome protocols and connectors, adapters or hardware protection devices, and can be transmitted through a single cable The HDMI signal of this unit, like Apple's Macbook, can be seamlessly grafted to a TV or monitor.
All devices equipped with a USB-Type C interface, including mobile phones, tablet computers, etc., previously required an adapter to output signals to a display with HDMI function. Now there is no need to use a converter anymore, just use a cable the cable can be realized perfectly. At present, Android’s high-end mobile phones are basically equipped with a USB-Type C interface, while Apple’s Macbook is the first device equipped with this interface. ASUS has also launched this type of product. It is expected that more products will be equipped with USB in the future.
With the gradual popularization of the USB-Type C interface, the importance of HDMI switching will also become apparent. HDMI is the leading display interface and has been installed on billions of displays. It is estimated that in 2016, the shipment of HDMI-enabled display devices will reach nearly 290 million units, including projectors, monitors and 100% flat-panel TVs. The USB Type-C connector is small in size and can be plugged in both front and back. Of course, it has a wide range of uses, and the connection is also very simple.
It is reported that the HDMI switch mode specification will fully support HDMI 1.4b functions, such as up to 4K resolution, audio return channel (ARC), 3D, HDMI Ethernet channel and consumer electronics control (CEC). The HDMI cable will use the USB Type-C connector on the source side and any HDMI connector on the display side. Other transition mode display technologies require various adapters or hardware protection devices to connect to the HDMI display. When using the HDMI transition mode, the connection can be achieved through a single USB Type-C to HDMI cable.
Rob Tobias, president of the HDMI licensing company, said that the reason for this change is that the USB-Type C interface has become the mainstream of mobile devices. In order to allow these devices to easily connect to HDMI-enabled displays, the shipment of HDMI products can be maintained. With continued growth, HDMI has launched this product. This specification will also attract more source devices that use HDMI. In order to facilitate consumer identification and ease of use, each cable will have the HDMI logo.
The publication of such a transfer specification can be said to be a boon for the majority of USB-Type C interface devices. Especially Apple users, as we all know, Apple users, especially Macbook users, because the notebook is only equipped with a USB-Type C interface, they always need to bring an additional HDMI adapter when they need to demonstrate. The release of this interface specification now brings greater convenience to the use of devices with a USB-Type C interface.
