<\/a>\u010co je Instaport a r\u00fdchly prep\u00edna\u010d HDMI<\/strong><\/h2>\n\n\n\n

InstaPort je produktom spolo\u010dnosti Silicon Image<\/strong>.<\/p>\n\n\n\n

R\u00fdchly prep\u00edna\u010d HDMI je v\u00fdvoj spolo\u010dnosti Synopsys.<\/strong><\/p>\n\n\n\n

Tieto dve technol\u00f3gie s\u00fa \u00faplne rovnak\u00e9 a princ\u00edp ich fungovania je rovnak\u00fd. Napr\u00edklad existuj\u00fa d\u017e\u00ednsy Lee a d\u017e\u00ednsy Levis, ale plnia rovnak\u00fa funkciu.<\/p>\n\n\n\n

Spolo\u010dnos\u0165 Synopsys vyvinula technol\u00f3giu podobn\u00fa r\u00fdchlemu prep\u00edna\u010du HDMI. \u00da\u010del t\u00fdchto technol\u00f3gi\u00ed je rovnak\u00fd – umo\u017eni\u0165 r\u00fdchle prep\u00ednanie medzi vstupmi HDMI. Sign\u00e1l z vybran\u00e9ho vstupu HDMI sa na obrazovke telev\u00edzora objav\u00ed po 5 a\u017e 10 sekund\u00e1ch. To je \u010das potrebn\u00fd na vytvorenie bezpe\u010dn\u00e9ho spojenia, ktor\u00e9 zabra\u0148uje kop\u00edrovaniu videa. Tvorcovia filmov a v\u00fdrobcovia zariaden\u00ed na prehr\u00e1vanie videa sa dohodli, \u017ee streamovan\u00e9 video sa bude pren\u00e1\u0161a\u0165 v \u0161ifrovanej podobe, \u010do zabr\u00e1ni hromadn\u00e9mu kop\u00edrovaniu filmov. Mnoh\u00fdm \u013eu\u010fom v\u0161ak vad\u00ed, \u017ee pri prep\u00ednan\u00ed portov HDMI trv\u00e1 dlho, k\u00fdm sa video objav\u00ed na obrazovke telev\u00edzora. To vyvol\u00e1va ot\u00e1zku, \u010di v\u0161etko funguje, alebo sa pozer\u00e1m len na pr\u00e1zdnu obrazovku.<\/p>\n\n\n\n

<\/a>Ako funguje r\u00fdchly prep\u00edna\u010d HDMI<\/strong><\/h2>\n\n\n\n

R\u00fdchly prep\u00edna\u010d HDMI funguje tak, \u017ee telev\u00edzor m\u00e1 \u0161peci\u00e1lne zariadenie (medziprij\u00edma\u010d) s \u010fal\u0161\u00edmi \u010dipmi HDCP, cez ktor\u00e9 prech\u00e1dza videosign\u00e1l, a a\u017e po \u010dipoch HDCP sa videoprenos dostane do prij\u00edma\u010da HDMI. Existuj\u00fa telev\u00edzory, ktor\u00e9 nemaj\u00fa v\u0161etky porty podporuj\u00face HDCP, tak\u00e9to telev\u00edzory s\u00fa pod\u013ea toho ozna\u010den\u00e9, napr\u00edklad HDMI2 HDCP, \u010do znamen\u00e1, \u017ee druh\u00fd port HDMI podporuje HDCP.<\/p>\n\n\n\n

Teraz o tom, ako to funguje v praxi. Napr\u00edklad jeden vstup HDMI na telev\u00edzore je pripojen\u00fd k prehr\u00e1va\u010du Blue Ray a vy sledujete video z multimedi\u00e1lneho prehr\u00e1va\u010da, napr\u00edklad Roku TV. Ke\u010f prep\u00ednate medzi vstupmi HDMI, obraz na telev\u00edzore sa zobraz\u00ed ve\u013emi r\u00fdchlo. Ka\u017ed\u00fd port HDMI m\u00e1 \u010dip HDCP, zariadenie pripojen\u00e9 k telev\u00edzoru vopred inicializuje bezpe\u010dn\u00e9 spojenie medzi zariadeniami. Sign\u00e1l z nepou\u017e\u00edvan\u00e9ho portu HDMI sa v\u0161ak nepou\u017e\u00edva, nemus\u00ed by\u0165 \u017eiadny obraz, len si obe zariadenia vymie\u0148aj\u00fa protokoly zabezpe\u010den\u00e9ho pripojenia a s\u00fa pripraven\u00e9 na pr\u00e1cu. Pri prep\u00ednan\u00ed pr\u00edjmu videa z jedn\u00e9ho portu HDMI na druh\u00fd, preto\u017ee zabezpe\u010den\u00e9 pripojenie je u\u017e vytvoren\u00e9, trv\u00e1 prep\u00ednanie medzi vstupmi HDMI pribli\u017ene 1 sekundu. Je to pohodln\u00e9 pre pou\u017e\u00edvate\u013ea, implement\u00e1cia tejto sch\u00e9my pripojenia portov HDMI nestoj\u00ed ve\u013ea pe\u0148az\u00ed, m\u00f4\u017ee to by\u0165 len asi 5 a\u017e 10 dol\u00e1rov.<\/p>\n\n\n\n

Je to v\u00fdhodn\u00e9, ale v\u00fdrobcovia sa zatia\u013e sna\u017eia, aby tak\u00e9to porty mali len najvy\u0161\u0161ie modely telev\u00edzorov. Rob\u00ed sa to z\u00e1merne, \u0161pi\u010dkov\u00e9 modely by mali ma\u0165 \u010do najviac pokro\u010dil\u00fdch funkci\u00ed.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
