HDMI Splitter, What Is It, How Does An HDMI Work?

Most televisions now support the use of HDMI to send out High Definition signals. HDMI is popular as it is able to transmit both audio and video signals. It also supports high-resolution audio and video formats. Sometimes, you may want to have the same video playing on multiple displays; in such cases, we use what is called an HDMI splitter. This post breaks down everything you need to know about what an HDMI splitter is, what it can do, and how it works. 

What is an HDMI Splitter

This is a device that is used to split one HDMI signal from the source device into several HDMI signals and sends it different devices. for example, it will split the signal from a source device such as game console, blu-ray player into different displays and these will show the same exact picture. 

Other HDMI splitters are not capable of splitting the HDMI signal into several signals. This happens because of a feature called High Bandwidth Digital Content Products. This feature is usually found in most media streamers, cables and TVS. This is there to ensure that the content you want to play is not pirated. 

This HDCP will first establish a connection between your screen and the media streamer. It will also encrypt the signal and prevent illegal and unauthorized recording of content on your screen. If your setup is not HDCP compliant, you will not be able to use the HDMI splitter and have many error messages rather than the intended content. 

Some HDMI splitters can circumvent this HDCP restriction. This happens because of the fallback mode that is in HDCP. This mode makes it possible for compliant content to play normally at a lower resolution when the setup used is nl HDCP compliant. 

It is not illegal for you to split the HDMI signal if you are doing it for honest reasons like creating legal backups, recording your gaming sessions, and more. However, if you are doing it to make copies and distribute any content without the proper authorization, then it is illegal.
