    \nDal\u0161\u00edm v\u00fdvojem protokolu byla integrace DMX512 do s\u00ed\u0165ov\u00e9ho protokolu Art-Net.
    \nArt-Net je jednoduch\u00e1 implementace protokolu DMX512 p\u0159es UDP, ve kter\u00e9 se informace o \u0159\u00edzen\u00ed kan\u00e1l\u016f p\u0159en\u00e1\u0161ej\u00ed v IP paketech, obvykle v m\u00edstn\u00ed s\u00edti (LAN) pomoc\u00ed technologie Ethernet. Art-Net je protokol s odezvou. Obvykle maj\u00ed za\u0159\u00edzen\u00ed pracuj\u00edc\u00ed podle Art-Net funkci zp\u011btn\u00e9 vazby na p\u0159ijat\u00e1 data. Nap\u0159\u00edklad za\u0159\u00edzen\u00ed obdr\u017eelo data a m\u016f\u017ee poslat odpov\u011b\u010f, \u017ee je obdr\u017eelo.<\/p>\n

    ArtNet m\u016f\u017ee p\u0159en\u00e1\u0161et naprosto v\u0161echno, v\u010detn\u011b soubor\u016f. P\u016fvodn\u011b m\u016f\u017ee ArtNet realizovat p\u0159enos hodnot a pozic fader\u016f, sou\u0159adnice za\u0159\u00edzen\u00ed a tak\u00e9 m\u016f\u017ee p\u0159en\u00e1\u0161et \u010dasov\u00fd k\u00f3d (adresov\u011b-\u010dasov\u00fd k\u00f3d \u2014 digit\u00e1ln\u00ed data o \u010dase, kter\u00e1 jsou zaznamen\u00e1v\u00e1na a p\u0159en\u00e1\u0161ena spolu s obrazem nebo zvukem. Pou\u017e\u00edv\u00e1 se pro synchronizaci r\u016fzn\u00fdch mediam syst\u00e9m\u016f \u2014 zvuk, video, sv\u011btlo atd.).<\/p>\n

    Za\u0159\u00edzen\u00ed ArtNet pou\u017e\u00edvaj\u00ed k komunikaci mezi sebou takzvan\u00e9 uzly (Nodes). Jako uzly mohou fungovat p\u0159evodn\u00edky Art-Net do fyzick\u00e9ho DMX512, nebo sv\u011bteln\u00e9 za\u0159\u00edzen\u00ed \u010di vybaven\u00ed, kter\u00e9 ji\u017e m\u00e1 vestav\u011bn\u00e9 rozhran\u00ed Art-Net. Uzly se mohou p\u0159ihl\u00e1sit (poslouchat) server. Z\u00e1rove\u0148 server m\u016f\u017ee distribuovat pakety jak v\u0161em uzl\u016fm ArtNet, tak i jednotliv\u011b vybran\u00fdm. Uzly trochu p\u0159ipom\u00ednaj\u00ed soci\u00e1ln\u00ed s\u00ed\u0165, mohou b\u00fdt p\u0159ihl\u00e1\u0161eny k serveru a z\u00e1rove\u0148 server m\u016f\u017ee ignorovat n\u011bkter\u00e9 uzly. Jako server Art-Net m\u016f\u017ee slou\u017eit po\u010d\u00edta\u010d se sv\u011bteln\u00fdm softwarem nebo sv\u011bteln\u00fd pult. Nejjednodu\u0161\u0161\u00ed zp\u016fsob realizace protokolu je Broadcast, funguj\u00edc\u00ed na principu rozhlasov\u00e9 stanice. Ta vys\u00edl\u00e1 pro v\u0161echny poslucha\u010de, a poslucha\u010di mohou bu\u010f zas\u00edlan\u00fd sign\u00e1l p\u0159ijmout, nebo ne.<\/p>\n

    Ka\u017ed\u00e9 prostor z 512 DMX kan\u00e1l\u016f v protokolu Art-Net se naz\u00fdv\u00e1 Universe (ang. Vesm\u00edr). Ka\u017ed\u00fd uzel (za\u0159\u00edzen\u00ed) m\u016f\u017ee podporovat maxim\u00e1ln\u011b 1024 DMX kan\u00e1l\u016f (2 Universes) na jedn\u00e9 IP adrese. Ka\u017ed\u00fdch 16 Universes je spojeno do pods\u00edt\u011b (Subnet \u2014 nezam\u011b\u0148ovat s maskou pods\u00edt\u011b). Skupina ze 16 pods\u00edt\u00ed (256 Universes) tvo\u0159\u00ed s\u00ed\u0165 (Net). Maxim\u00e1ln\u00ed po\u010det s\u00edt\u00ed je 128. Celkem m\u016f\u017ee v protokolu Art-Net po\u010det uzl\u016f dos\u00e1hnout 32768 ks (256 Universes x 128 Nets), ka\u017ed\u00fd s 512 DMX kan\u00e1ly. <\/p>\n
