Essential Video Coding

<h2 id="concept">Concept</h2> <p>The publicly available requirements document<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> outlines a development process that is defensive against patent threats: Two sets of coding tools, <i>base</i> and <i>enhanced</i>, are defined: </p> <ul><li>The base consist of <i>tools that were made public more than 20 years ago or for which a Type 1 declaration is received</i>. Type 1, or option 1, means "royalty-free", in the nomenclature used in ISO documents.<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a></li> <li>The "enhanced" set consists of 21<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> other tools which have passed an extra compression efficiency justification and which can be disabled individually.</li></ul> <p>Each of the 21 <a href="/facts/Payable/paPtrc3d">payable</a> tools can have separately acquired and separately <a href="/facts/Negotiation/QyUsoN6M">negotiated</a> and separately <a href="/facts/Trade/S13U8JKr">Traded</a> <a href="/facts/License_agreement/xaP3U6ga">License agreements</a>.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> Each can be individually turned off and, when necessary, replaced by a corresponding <a href="/facts/Cost_free/YDd7Hjzm">cost free</a> baseline profile tool.

Though the EVC Main profile uses royalty-bearing "tools," these can be switched on and off with "limited loss of performance." This was the model deployed by Divideon and their xvc codec, and, in theory, it allows those deploying the technology to pick and choose both the performance and the associated royalty cost.
