1.What is HDbaseT?+
HDBaseT is fully HDMI-compliant. HDBasetT connects commercial, industrial, and CE devices and AV receivers to compatible digital audio devices, computer monitors, multi-touch displays, digital televisions, and digital video projectors.
HDBaseT Technology stands out with it's 5 Play feature set. The 5 Play feature set focuses on audiovisual (AV), Ethernet, USB, Control Signals, and Power-over-HDBaseT (PoH).
2.HDbaseT video support+HDbaseT supports uncompressed video to a network of devices or as a point-to-point to accurately render gaming graphics and features. Supports TV and PC video formats (e.g., standard, enhanced, high-definition, Ultra-HD and 3D video).
HDBaset 1.0 and 2.0 support uncompressed video up to:
4K at 30Hz with 8-bit 4:4:4 color coding,
4K at 30 Hz up to 12-bit 4:2:2 and high dynamic range (HDR),
4K at 30 Hz with Dolby Vision standard mode,
4K at 60 Hz with 8-bit 4:2:0 color coding.
HDBaseT 3.0 supports uncompressed video up to:
4K at 60Hz with 8-bit 4:4:4 color coding,
4K at 60 Hz up to 12-bit 4:2:2 and high dynamic range (HDR),
4K at 60 Hz with Dolby Vision standard mode.
3.HDbaseT Audio support+HDMI carries audio without the need for multiple cables, supporting all standard HDMI audio formats (e.g., either compressed or uncompressed 32 channels of high-resolution 24-bit 192kHz audio, or 2-channel audio with a sampling frequency up to 1.536MHz).
HDBaseT 2.0 supports separate bi-directional S/PDIF audio that was introduced with the HDMI 1.4 specification, the upstream channel of which can optionally be used to carry HDMI Audio Return Channel.
With bandwith increase, HDBasetT 3.0 provides optional support HDMI enhanced Audio Return Channel (eARC), for all of the same audio formats upstream already available in the main HDMI downstream signal ( e.g., immersive and object-based audio such as Dolby Atmos or DTS).
4.Near zero latency+The specification allows for negligible latency: less than 10 microseconds (.01 milliseconds) over 100m of cable. For example, a 60hz refresh rate means a full image is displayed after 16.67 ms. Adding 0.01 ms is only a 0.06% increase in the signal latency.
5.Ethernet support+HDBaseT 1.0 and 2.0 supports the 100 Mbit/s version of Ethernet over twisted pair. This provides Internet access to devices such as CE devices, computers, and smart TVs to communicate with each other and access multimedia content on the local network. HDBaseT 3.0 increases this capability to 1000 Base-T (Gigabit) Ethernet.
6.USB support+HDBaseT 2.0 supports for USB 2.0, with a capacity for the simultaneous connection of up to 7 USB devices and a transfer rate up to 190 Mb/s. HDBaseT 3.0 increases this to 350 Mb/s.
7.Control signals+HDBaseT delivers HDMI Consumer Electronics Control (CEC) protocol signals that control basic functionality such as power-on, power-off and play/stop, along with RS232 and consumer IR (remote control) commands.
8.PoH (Power over HDbaseT)+HDBaseT provides power-over-HDBaseT (PoH), provisioning up to 100 W of operating DC power to CE devices, such as monitors and TVs. If a display is enabled as a 100W powered device (PD), and is connected to a matching PoH transmitter (power sourcing equipment, PSE), the display will be able to draw its operating power through the HDBaseT link, not requiring a separate power connection.
