Analogix transmitter merges DisplayPort and HDMI

What does HDMI stand for?
High-Definition Multimedia Interface (HDMI) is digital, point-to-point interface for A/V signals. Introduced in 2002, it is designed as a single-cable solution for home theater and consumer electronics equipment. It is electrically similar to video-only DVI, and although it also includes audio, HDMI plugs and sockets, it is considerably smaller.

What is DisplayPort?
DisplayPort is a digital display interface standard put forth by the Video Electronics Standards Association ( VESA ) since 2006. It defines a royalty-free (as of 2009), digital audio/video interconnect, intended to be used primarily between a computer and its display monitor, or a computer and a home-theater system. The first version was approved in May 2006 and version 1.1a was approved in January 2008.
DisplayPort signaling and protocol are different from those for DVI or HDMI. The interface includes optional DisplayPort Content Protection (DPCP) copy-protection from Philips, which uses 128bit AES encryption. Version 1.1 adds support for HDCP.
