Hi, I'm finally watching TV in my Home FreeBSD !!! Hurray !!! But, I'm in Brazil, and Brazil uses a very interesting video system, knonw as PAL/M. For the purposes of image tracing, it's like NTSC, but for chroma, it's like PAL. This means that when I use a NTSC tuner to see PAL/Mbroadcast I can see the image, but the colors are incorrect. When I have luck, they disapear for complete. Here's the dmesg of interest about my card: bktr0 <BrookTree 848> rev 18 int a irq 10 on pci0:10 Hauppauge WinCast/TV, Philips NTSC tuner. This tuner has the capability to detect PAL/M images, and the Windows tuner indeed do this. It would be good to have this in fxtv too. I've taken a fast look in the kernel driver sources. It has a define of TTYPE_PAL_M, but does not use it anywhere. Is there any plan to include support for it ? How could I help ? For those more interested, here are some parameters of PAL/M: Hf = 15734.26 Hz Vf = 59.94 Hz Chroma Freq: 3.57561149 MHz Scan: 525 lines, 30 fps Jonny -- Joao Carlos Mendes Luis jonny@gta.ufrj.br +55 21 290-4698 jonny@coppe.ufrj.br Universidade Federal do Rio de Janeiro UFRJ/COPPE/CISI PGP fingerprint: 29 C0 50 B9 B6 3E 58 F2 83 5F E3 26 BF 0F EA 67
