A followup to my recent post about Teletext on bt848 cards. I still cannot get the Java teletext viewing program to run in Netscape. I tried 4.04 4.07 and 4.5 However, it does work with the appletviewer in JDK 1.1.7 As a summary. The bt848 driver outputs raw VBI data (raw data from the top of the TV signal) to /dev/vbi. The vbidecode program reads this and extracts teletext pages. These are saved as 100_01.vtx 101_01.vtx 102_01.vtx etc for pages 100,101,102 Then you need a vtx viewer. 2 exist. One is written in Java. It runs just fine in the JDK applet viewer. (cannot make it run in Netscape) One is written in C as an X11 application. It works. Is a pain to set up. Puts files all over the place and needs speical X Fonts setting up. It has many more features. Infact the feature list is very impressive. But for now I just want you to experiment with the Java viewer as it is much simpler to support.
