Hi, I've uploaded some initial teletext decoding software for the FreeBSD bt848/878 driver. This is for 3.1 and 4.x users. Have a look in ftp://telepresence.dmem.strath.ac.uk/pub/bt848/teletext There is a replacement bt848 driver (brktree_reg.h and brooktree848.c) use these to replace the existing files in /sys/pci There is also a Java Teletext viewer. Now I got this to run on Win95, but my Netscape 4.04 browser failed to run run the Java. I'm trying a newer Java run-time right now. Untar the Java teletext viewer. In it you will also find vbidecode-1.0 Apply the patch to it (as specified int he README) and make vbidecode. This reads raw data from /dev/vbi and generates .vtx files. 1 file per teletext page. The java viewer then reads the VTX files. NOTES: when you run vbidecode, you must have subdirectories created for vbidecode to save the pages into run vbidecode -v to see the titles of your teletext stations. in the UK I have to do this mkdir ceefax mkdir 4-text mkdir vh-1 ./vbidecode and it saves BBC ceefax pages into ./ceefax and vh-1 pages into ./vh1 To tune into the TV station, use the standard fxtv, but RESIZE the window so it contains an interlaced screen (ie the height > 300 pixels) good luck. please try it. bye roger p.s. I'm on vacation from saturday 17th until thursday 22nd, so there will be no help from me until then. -- Roger Hardiman Strathclyde Uni Telepresence Research Group, Glasgow, Scotland. http://telepresence.dmem.strath.ac.uk 0141 548 2897 roger@cs.strath.ac.uk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
