HDMI Connections

HDMI connections are a type of digital interface created in 2002 to replace the analog connections that were used at that time for the transmission of video and audio.

It allows the transmission of uncompressed digital video and audio between two devices through a single cable. Its main basic features include the ability to transmit video signal in high definition (1080p) plus up to 8 audio channels simultaneously.

The great virtue of HDMI connections is the ability to be updated with new versions that add improvements and / or new features to the interface. For example, currently in version 2.0 is already possible the transmission of ultra high definition signals 4K and up to 32 audio channels through a single HDMI cable.
