HDBaseT, which is composed of Japanese and Korean home appliance manufacturers LG, Samsung, Sony, and Israel's semiconductor company Valens Semiconductor, formed the HDBaseT alliance. In 2009, it passed Intel's HDCP certification. At the end of June 2010, HDBaseT 1.0 was determined. Formal specification. HDBaseT does not redesign a new interface like HDMI and Display Port. Instead, it uses the 8P8C (RJ45) connector, which is no stranger to the public. It is commonly known as a crystal head or an Ethernet connector. The transmission medium uses a very easy and common network cable. In addition to providing video signal transmission, the HDBaseT standard also features network connectivity and Power over Ethernet (POE). 
The elements that gave birth to HDBaseT are roughly the following:
1. The transmission distance of the HDMI cable is only about 5 meters, which greatly limits the use range of the HD device, and the HDBaseT transmission distance can reach 100 meters.
2. HDMI cable is expensive, and HDBaseT uses a cheap and easy-to-use CAT5/6 Ethernet cable as the transmission medium.
3. HDMI is a closed standard. Vendors use the HDMI interface to pay a certain license fee, while HDBaseT is an open standard and does not require additional fees.
4. The HDBaseT standard currently supports a maximum transmission rate of 20Gb/s, which is four times the maximum transmission rate of HDMI of 5Gb/s, and can fully satisfy all uncompressed 1080p or more clear 4K x 2K video transmission.
The HDBaseT Alliance rejoined InfoComm China 2014 in Beijing this year to consolidate the development of HDBaseT technology in China and introduce more products that support HDBaseT technology. With the industry's recognition of HDBaseT technology, the number of members of the HDBaseT Alliance has doubled compared to last year, and now there are 92 members.
CREATOR is the first audio and video product manufacturer to join the HDBaseT Industry Transmission Standards Alliance. Since joining the alliance in 2012, CREATOR has been paying attention to the development and production of signal switching transmission products that support the HDBaseT standard protocol.
Among them, CM hybrid matrix switcher we have developed and produced HDBaseT input card Xin-CAT8 and HDBaseT output card Xout-CAT8, CM hybrid matrix with HDBaseT CAT5 engineering series of transmitters and receivers, through the ordinary CAT5e/6 network cable Uncompressed transmission, support for a variety of analog, digital audio and video signals and a variety of control signals. It meets the high-definition signal switching and transmission of small and medium-sized places in various types of industries. Widely used in schools, military, armed police, public security, post and telecommunications, transportation, aerospace, railway, water conservancy, electricity, securities, flood control, petroleum, chemical, financial, taxation, industry and commerce, hospitals, entertainment, security, government and other institutions.

In addition, CREATOR has also designed a professional twisted pair matrix - CAT5 matrix switcher, the protocol supported by its input and output ports is HDBaseT transmission protocol. This matrix satisfies the requirements of using a common transmission cable while transmitting high-definition signals and embedded bidirectional control signals over long distances in a multimedia application system.

It is said that the latest HDBaseT 2.0 standard will become the next-generation voice signal transmission standard, which not only enables 4K high-definition signal transmission, but also supports 5.1-channel support, which is compatible with almost all audio and video signal sources, while considering mobile devices. Also added support for USB 2.0.
Let us look forward to the technical research of the HDBaseT 2.0 standard, and continue to pay attention to CREATOR's fast technical research, and look forward to CREATOR's next technological leap.
