Ethernet function

The HDMI cable from manufacturer BlackBox, type VCB-HDMI-003M, is a high-speed HDMI cable with Ethernet functionality, designed for the transmission of digital video and audio signals as well as network data over a single cable. It is used to connect devices with HDMI interfaces, such as Blu-ray players, laptops, HDTV receivers, digital televisions, or gaming consoles, enabling the use of modern display technologies. The cable construction is optimized for stable and interference-free signal transmission, with double shielding consisting of foil tape and braided shielding minimizing signal loss and screen disturbances. The jacket is made of PVC, ensuring good mechanical stability and flexibility.

Applications
This cable is suitable for use in home cinema systems, office and corporate networks, as well as multimedia applications requiring high bandwidth and simultaneous network connectivity. It enables networking of HDMI Ethernet Channel-compatible devices without additional network cables, which is particularly advantageous when connecting Blu-ray players, gaming consoles, or Smart TVs. The length of 3 meters makes it ideal for typical arrangements in living and workspaces, where devices are positioned up to 3 m apart.

Functions and Features in Detail
The cable supports the transmission of compressed video at high bandwidth, multi-channel digital audio, format and control data, as well as Ethernet network data. It is certified as HDMI Category 2, confirming compliance with HDMI standard requirements for high-speed transmissions. The transmission bandwidth reaches up to 10.2 Gbps, equivalent to a frequency of 340 MHz. This bandwidth enables video signal transmission at resolutions up to 2K x 4K, 3D video, and Deep Color. Additionally, the cable supports advanced audio formats such as Dolby® True HD and DTS-HD Master Audio. The Ethernet function enables networking of devices via the HDMI Ethernet Channel, eliminating the need for a separate network cable.

Technology Explained Simply
The HDMI Ethernet Channel function utilizes a dedicated data channel within the cable to transmit network data between compatible devices. This is particularly useful when multiple devices are connected via HDMI and simultaneously require network access, for example, to stream content or perform firmware updates. The double shielding ensures that external electromagnetic interference does not affect the signal, resulting in clear and noise-free video and audio playback. The conductor gauge is 28 AWG, specified for cables up to 5 m in length, ensuring sufficient power and signal transmission.

Compatibility and Accessories
The cable is backward compatible with older HDMI cables without Ethernet functionality, allowing it to be used with devices that do not support HDMI Ethernet. It is designed for use with devices featuring HDMI interfaces, particularly Blu-ray players, laptops, HDTV receivers, digital televisions, and DVDs. Support for 4K resolution, 3D, and Deep Color makes it suitable for modern high-end display technologies. Certification as HDMI Category 2 guarantees compliance with official HDMI standard requirements.

Installation and Mounting
Installation is performed by simply plugging the HDMI connectors into the corresponding sockets on the devices. No additional tools or configurations are required. The cable connection is mechanically stable and can be disconnected without tools. The PVC jacket provides sufficient protection against mechanical stress and is suitable for indoor use.

Operational Advantages
By combining video, audio, and network transmission in a single cable, the number of required connections is reduced, simplifying installation and improving the appearance of device setups. The high-speed transmission ensures smooth video playback even at high resolutions, and the Ethernet function enables a cable-free network connection between compatible devices. The 25-year Double Diamond™ warranty underscores the product’s durability and reliability.
