Zatímco jas je přenášen se všemi detaily, některé detaily v komponentách barevného signálu bez informací o jasu lze odstranit snížením rozlišení odpočtů (filtrování nebo zprůměrování).<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>YUV kóduje barevný obraz nebo video s ohledem na lidské vnímání, což umožňuje snížení šířky pásma pro barevné složky, a tím obvykle umožňuje efektivnější maskování chyb přenosu nebo artefaktů komprese vnímáním člověka, než kdyby se používala "přímá" RGB reprezentace.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Použití"><span id="Pou.C5.BEit.C3.AD"></span>Použití</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=YUV&veaction=edit&section=1" title="Editace sekce: Použití" class="mw-editsection-visualeditor"><span>editovat</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=YUV&action=edit&section=1" title="Editovat zdrojový kód sekce Použití"><span>editovat zdroj</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Barevný model YUV se začal používat v systémech pro přenos a vysílání videa (formáty jako například SECAM, NTSC, PAL), protože je kompatibilní s tradičními černobílými přijímači, které dokážou zobrazit pouze jasový kanál "Y".
