HDMI Extender
HDMI cables only reach 99 feet before signal deterioration settles in. If you've ever experienced your display pixelating, lagging, even with total picture loss, a common fix is an HDMI extender.
Performance
To extend an HDMI signal, HDMI extenders use category cables, or CAT cables CAT cables; basically what you connect your laptop to your router with for internet access. CAT cables are more efficient to run through walls, attics, and crawl spaces. versus an HDMI cable with a bulky connector head. Another benefit to CAT cables is they are less likely to fail over time, unlike HDMI cables.
An HDMI signal degrades as the distance goes further. Generally, 65 feet is considered the maximum reliable length for an HDMI signal and even shorter for a higher resolution video.
The HDMI signal is also vulnerable to interference caused by high-voltage electric lines and electromagnetic devices. When it comes to an A/V environment, it always requires massive cables and complicated A/V setups.
Though the consequence is minor sometimes, it would not be acceptable for professional audio visual integrations and applications that require smooth presentation of video and audio.
When it comes to signal transmission, chipsets are crucial components to decide the performance of HDMI extenders. Some products can be sold at incredibly low prices because they don't have chipsets in them and can only bypass the signal with unstable performance and short transmission distances.
However, the products that have built-in chipsets do otherwise.
SYONG HDMI Extender devices supporting Video/ Audio /USB /IR /UART over IP are built based on AM8270. an in-house developed and highly integrated SoC with HDMI receiver and Gigabit PHY embedded.
An HDMI loop-out allows an additional display to be connected on the transmitter side.
Anappealing feature of some HDMI extenders is Power Over Cable (PoC) and Power over Ethernet (PoE), which allows the extenders to be powered through the transmission cable itself. This means that only one end of the extender pair(either the transmitter or receiver) needs to be connected to a power source, simplifying installation and reducing clutter. PoC is particularly beneficial in setups where power outlets are scarce or inconveniently located relative tothe source or display device.
Transmit infrared （IR）remote signal. Allowing users to control the video source as if it were directly connected to the display via a standard HDMI connection. This feature adds a layer of convenience, enabling seamless interaction with the source content from the location of the display.
With the added benefit of controlling a keyboard and mouse from a remote location. KVM functionality allows remote control of a computer or media player from the display side using a keyboard and mouse.
Since HDMI signal can not carry a USB signal along with video and audio, you can only control a remote device overUSB interface(s). Fortunately, USB signals can be transmitted with HDMI overone single cable like CAT5e, optical fiber...etc.
