This is a good thread to bring this particular terminology into, because when I followed the links in the post to DLI to find out about the algorithm, I was greeted with a page containing no details, no specification, and links to a Windows .DLL and EXE.* In contrast, if I want to learn about the other codec in this comparison, I can download Rec H.265 from the ITU freely, ISO draft HEVC specifications freely, final ISO documents for little more than the cost to keep ISO running, use an official BSD-licensed reference implementation, and already find several high-quality independent open source implementations (for a one year old standard). A standard which, by the way, was developed by not one but two international standards bodies, the proceedings of which I can view online (http://mpeg.chiariglione.org/meetings http://mpeg.chiariglione.org/meetings). Maybe I've been in this for too long, but when I started, codecs like DLI were the norm rather than the exception. The top competitors at the time were Sorenson, On2 (VPx), RealNetworks, and Microsoft, and MPEG-4 had barely trickled out of the demo boxes in the form of a cracked copy of a MS draft implementation that ended in ";-)". Patent dangers were well known thanks to Fraunhofer's actions against LAME, but since they didn't extend to Europe where much open source codec development occurred, and since they were (before GPLv3) largely within a separate legal sphere from copyright issues, and since it had long been folk wisdom that doing video compression without stepping on someone's patent was impossible, they were seen as little more than an unavoidable detail (here's some source code, compile it yourself in America.) It was none other than H.264 (ostensibly with a lot of help from x264) that put an end to this era. So when I see folks putting the MPEG Licensing Authority (unaffiliated with ISO and MPEG, by the way) on a pedestal, and I see it a lot, and using it as an excuse to further technologically inferior codecs which are themselves (unlike MPEG standards) technically proprietary, I have a hard time reconciling the thought process. And to bring it up in response to a comparison against something like DLI? Give me a break. * https://sites.google.com/site/dlimagecomp https://sites.google.com/site/dlimagecomp
