At CES 2008, THX began talking about Media Director, a program that would get hardware and software to talk to one another via metadata, automatically running movies with the right audio and video parameters. THX is now assembling a database of 1000 popular movie titles, codenamed Aardvark, to assemble the metadata needed for each piece of content. And it's now using the HDMI Infoframe Analyzer, shown here, to test audio and video devices to ensure that they shake hands and exchange metadata with one another, sort of like digital beings swapping business cards in a bar.
