Typically, the output can be either an 39 s-video connection or composite video. Resolutions supported using the 40 chip's built in configurations are 640x480 or 800x600. Other possible 41 implementations may allow for double resolutions with some decimations 42 (e.g., a monitor running at 1280x960 but the TV out getting every other 43 pixel for 640x480). 39 40 This driver provides some access to the Brooktree bt869 found on some 41 video cards (like the 'Voodoo3 3000'). Typically, the output can be 42 either an s-video connection or composite video. Resolutions 43 supported using the chip's built in configurations are 640x480 or 44 800x600. In addition, a 720x576 PAL mode and a 720x480 NTSC mode, 45 both without overscan compensation, are supported - a convenient 46 configuration for video playback. 47 48 Other possible implementations may allow for double resolutions with some 49 decimations (e.g., a monitor running at 1280x960 but the TV out getting every 50 other pixel for 640x480). 44 51 45 52 46 53 Driver Features 47 54 --------------- 48 Stan ards: (US) NTSC or PAL (PAL untested)49 Res ultions: 640x480 and 800x60050 Depths: 16 bit or 32 (I forgot if 24 bit worked OK, it probably does)55 Standards: (US) NTSC or PAL 56 Resolutions: 640x480, 800x600, 720x576 (PAL only), 720x480 (NTSC only) 57 Depths: 16, 24 or 32 bits 51 58 Colorbars: Switch on the built-in color bar generator. (FYI- using a blue 52 59 filter, you should see only alternating bright stripes of equal brightness. 53 60 Adjust your TV's color and saturation if this isn't the case.) 61 SVideo: composite or s-video output. Also, theoretically, RGB output, though 62 this isn't tested and will require that your card presents all three DAC outputs 63 (the 3dfx Voodoo3 doesn't) 54 64 55 65 In your XF86Config file, you should have these entries for NTSC output: 56 66 57 67 ModeLine "640x480NTSC" 28.195793 640 656 658 784 480 520 525 600 68 ModeLine "720x480NTSC" 27.5 720 744 800 872 480 483 485 525 58 69 ModeLine "800x600NTSC" 38.769241 800 812 814 880 600 646 649 735 59 70 60 or for PAL (untested),71 or for PAL 61 72 62 73 ModeLine "640x480PAL" 29.50 640 675 678 944 480 530 535 625 74 ModeLine "720x576PAL" 27.50 720 744 800 880 576 581 583 625 63 75 ModeLine "800x600PAL" 36.00 800 818 820 960 600 653 655 750 64 76 … … 77 89 Chip Features 78 90 ------------- 79 The chip is very flexible and customizable for many standards.
