HDMI extenders and HDMI splitters differ in functionality, structure, application scenarios, and other aspects, with specific details as follows:
1)Function and Purpose:
HDMI Extender: Primarily used for long distance transmission of HDMI signals. It overcomes the length limitation of standard HDMI cables to achieve lossless or low-loss signal extension.
HDMI Splitter: Copies one input HDMI signal into multiple identical output signals. It enables synchronous signal distribution, allowing multiple display devices to show the same content simultaneously.
2)Interface Configuration:
HDMI Extender: Typically features a 1-in-1-out interface setup. It consists of a transmitter and a receiver, connected via transmission media such as Ethernet cables or fiber optics.
HDMI Splitter: Generally adopts a 1-in-multiple-out interface format. Common types include 1-in-2-out, 1-in-4-out, and 1-in-8-out. It allows one signal source to connect to multiple display devices based on requirements.
3)Signal Transmission Distance:
HDMI Extender: Supports long distance transmission. For example, it can extend signals to tens or even hundreds of meters via Ethernet cables, and even farther via fiber optics.
HDMI Splitter: Mainly used for short-distance signal distribution. Normally, the distance between each connected display device and the splitter should not be too long; otherwise, issues like signal attenuation may occur.
4)Device Structure:
HDMI Extender: Composed of a transmitter (Tx) and a receiver (Rx). The transmitter encodes and modulates the HDMI signal for transmission over media like Ethernet cables or fiber optics, while the receiver decodes and restores the received signal for output to the display device.
HDMI Splitter: Internally consists mainly of signal distribution chips and amplification circuits. It copies and amplifies the input HDMI signal, then distributes it to each output port.
5)Typical Application Scenarios:
HDMI Extender: Often used in scenarios such as long-distance screen mirroring for conference room large screens, signal transmission back for surveillance cameras, and remote deployment of digital signs. For instance, in a large conference room, it transmits the computer signal to a distant large screen via an extender.
HDMI Splitter: Suitable for scenarios such as multiple TVs in a mall playing the same advertisement, the main screen and auxiliary screen in a conference room displaying synchronously, and multi-device monitoring for live broadcasts. For example, in a mall, it transmits the signal from an advertising playback device to multiple TV screens simultaneously via a splitter.
