\nNa z\u00e1klad\u011b ozn\u00e1men\u00ed provozovatele satelitu Kopernikus DFS2, spole\u010dnosti Deutsche Telekom (DT), bylo ozn\u00e1meno ukon\u010den\u00ed telekomunika\u010dn\u00edho provozu na tomto satelitu do konce roku 2000. P\u0159\u00ed\u010dinou je indikace sn\u00ed\u017een\u00e9 z\u00e1soby paliva stabiliza\u010dn\u00edho syt\u00e9mu. Vzhledem k tomu, \u017ee zprovozn\u011bn\u00ed nov\u00e9ho satelitu Eurobird1, kter\u00fd nahrad\u00ed provoz DFS2 je pl\u00e1nov\u00e1no na za\u010d\u00e1tek II.\u010dtvrtlet\u00ed 2001, spole\u010dnost DT rozhodla o zaji\u0161t\u011bn\u00ed n\u00e1hradn\u00edho provozu. Z tohoto d\u016fvodu byl na pozici satelitu DFS 2 tj. 28,5 stupn\u011b v\u00fdchodn\u011b p\u0159esunut satelit Eutelsat II-F4.
\nNa tuto novou situaci musela \u010cesk\u00e1 televize (smluvn\u00ed partner v\u016f\u010di DT) a spole\u010dnost CzechLink (provoz uplinku a kompresn\u00ed technologie) reagovat a zajistit tak podm\u00ednky pro vys\u00edl\u00e1n\u00ed za nov\u00fdch podm\u00ednek. Sou\u010dasn\u011b bude muset b\u00fdt p\u0159eveden provoz na nov\u00fd satelit na v\u0161ech p\u0159ij\u00edmac\u00edch m\u00edstech a u jednotliv\u00fdch div\u00e1k\u016f \u010di poslucha\u010d\u016f. Co bude tedy tato zm\u011bna p\u0159edstavovat :<\/p>\n

Pro usnadn\u011bn\u00ed p\u0159echodu na nov\u00fd satelit \u010cT proto spolu s CzechLink zajistila na obdob\u00ed 4. – 15. prosince 2000 soub\u011b\u017en\u00fd p\u0159enos sv\u00fdch sign\u00e1l\u016f pomoc\u00ed obou satelit\u016f, tj vedle st\u00e1vaj\u00edc\u00edho DFS2 bude v provozu i programov\u00e1 nab\u00eddka na satelitu Eutelsat II-F4.
