There is only one slow teletext card with SAA5246. To read in the entire teletext data of a broadcaster I need much time and a smart-written (DOS) program. Dependent of the size (epecially the maximum count of subpages to one page) I need 1..2 hours to read in alomst all pages. With a statically programmed time-table I switch the satellite receiver by the computer, so I have following read-in times:
WDR: 0..1 a.m., Premiere: 1..2 a.m., Nord 3: 2..4 a.m., 3sat: 4..6 a.m., Nickelodeon/VH1: 6..7 a.m., Kabel1: 7..8 a.m., ARD: 8..9 a.m., DSF: 9..10 a.m., Eurosport: 10..11 a.m., MDR: 11..12 a.m., PRO 7: 12..1 p.m., RTL 2: 1..2 p.m., BR-Alpha: 2..3 p.m., Bayern 3: 3..4 p.m., ZDF: 4..5 p.m., Südwest 3: 5..6 p.m., SuperRTL: 6..7 p.m., n-TV: 7..8 p.m., Hessen: 8..9 p.m., ORB: 9..10 p.m., CNN: 10..11 p.m, SAT.1: 11..12 p.m.
Before these times above, downloadable teletext is always yesterday's.
