Please visit the respective website for detail. (*) Please refer to "Linux support" section for BTTV driver on Linux. D).Avoid Interrupt Conflict If your TV card goes with horizontal noise on video display window or if your PC locks up during the Windows boot or application launched, you may have an interrupt conflict. Try to put the TV capture card in another PCI slot or assign the interrupt in BIOS then reboot. If there are no free interrupts for the capture card, you need to find an unused device which has an interrupt reserved for it and free up its interrupt. The PC may reserves an interrupt for the PS/2 mouse, even though a PS/2 mouse is not being used. You may check to free up the USB or second IDE controller interrupts if you do not use them. To free up an interrupt, you must disable the peripheral not being used in BIOS by pressing <DEL> key when PC restarts. To remove the device in Windows 95/98, 1. Open "CONTROL PANEL" from "SETTINGS" of task bar. 2. Click on "SYSTEM", select the "DEVICE MANAGER". 3. Select the unused device and click "REMOVE". You may disable PCI SOUND CARD to check if the cards in conflict even no IRQ conflict reported in DEVICE MANAGER but the TV card goes with horizontal noise on video display window only. E).The LOAD LIBRARY FAIL Error Codes 1143 : You have to restart your computer when driver installed first time. 1157 : GRAPPLER.DLL is erased, you may copy from CD to C:\WINDOWS\SYSTEM or drivers are installed first time, you have to restart again. 1114 : TV card is not installed, IRQ in conflict, driver not proper installed or the video decoder (BT848/BT878) is out of order. Please copy your original TVCFG.BIN before uninstallation and copy this file to the application directory after updating. The TVUNINST.EXE is included because the makers may not delivery this file in CD. Please copy this file in original installed or other separate directory because it will kill itself and the other files in the same directory. Run TVUNINST and click to delete APPLICATION and then DRIVERS. You must have application deleted that kill the drivers and the registry. Be sure to restart the computer to install drivers and then install applications again. The previous version of TV application needs IVTVCTL.DLL and no more now. The new TV I2C/HW control dynamic link library is GRAPPLER.DLL instead. If you update driver with trouble because of the missing library file, copy GRAPPLER.DLL as IVTVCTL.DLL instead. Go the manufacture's website for the up to date drivers and applications. F).Update from Windows 95 to Windows 98 It may not work for some users update from Windows 95 to Windows 98. The way to fix this problem is to install driver and application again. Please copy your original information file TVCFG.BIN before uninstallation and copy this file to the application installed directory after updating. Please run TV Uninstaller (TVUNINST.EXE) from installed directory. For the sake of program architecture, please uninstall applications first and drivers next. Be sure to restart the computer to install drivers and then applications again. Note : Do not just run uninstall from "Add/Remove" of the CONTROL PANEL. Please download the file TVUNINST.EXE if it is not deliveried in the CD-ROM released, copy this file in original installed directory and run. G).Resource Leakage from Brooktree driver There exists one bug in Brooktree's Closed Caption driver BT84XCC.DLL or BTCC32.DLL or BTCC.DLL that makes resource leakage every time you resize the video window or change the video mode and then the PC may locked up. Please refer to section W, "Closed Caption Support". H).DirectDraw, OSD and Full Screen Brooktree drivers have capability to stream live video over the PCI bus directly into the graphics frame buffer. In order to achieve this, Brooktree needs to know an address in the frame buffer or offscreen memory on the graphics card. Microsoft's DirectDraw interface (DDI) is the tool the drivers use to obtain such an address. DirectDraw uses the concept of a surface to describe a rectangular region of either an on-screen or offscreen video frame buffer. The surface encapsulates attributes and operations that can be performed by a drawing application. A surface in this context is a pixel data buffer and set of functions that operate on that data ( i.e. blitting ). Brooktree can work with both primary and overlay surfaces. The primary surface cooresponds to the visible display frame buffer. The overlay surface is stored in offscreen memory on the graphics card. Data from an overlay surface can be overlaid on top of primary surface. The primary surface is usually in one of the RGB formats; the overlay surface may be in either an RGB or YUV format. Overlay hardware support of a graphics chip performs color space translation if required when displaying overlay data. Overlaying is based on the principle of color keying. A region of the primary surface is painted with a unique key color (Brooktree uses magenta). Overlay hardware in the graphics controller compares the color of the primary surface with the key color and when they match data from overlay surface's buffer is displayed; if colors do not match graphics are displayed. Overlay surfaces are positioned relative to the primary surface through DirectDraw functions. Brooktree drivers use the following scheme to allocate the required DirectDraw surface: First an attempt is made to create the overlay surface. If successful, it is used. Brooktree transfers data into overlay surface (stored somewhere in the off-screen memory). This is the preferred mode of operation. No clipping issues are present, as key color hardware takes care of this. If a drop-down menu obscures the video window, then the key color will be replaced with the menu colors and overlay hardware will fail the key color comparison. One big advantage of overlay is the OSD (On Screen Display) function for user to display favorite information on screen for a while. Another advantage of using overlay surface is full screen display, because interpolated upscaling can be performed, making it possible to fill the entire screen, even at display sizes greater than the video standard's native resolution. Some graphics controllers have difficulties implementing overlay due to either controller bandwidth or internal video FIFO limitations. S3 Virge exhibits a bandwidth problem, ATI's 264VT has limited overlay width, Tseng VGA does not support color key natively, and Matrox G200 does not support color key natively, too. If overlay surface creation fails, or is unsupported by the graphics controller, the primary surface is used to display video. In this mode Brooktree transfers video pixels directly into visible portion of frame memory. No color key is used and clipping information must be provided to the driver by the operating system to avoid drawing over menus, other windows etc. DirectDraw provides an API to obtain clip list information for a given window. When such clip list changes, Brooktree's RISC program is updated to accommodate it, so RISC program is paused, modified and restarted. Another disadvantage of using primary surface is that in 256 color mode image quality suffers since the image must be dithered from true color. Performance Notes Some overlay graphics controllers may not have implemented the PCI bus correctly and may in fact slow it down. In some cases, primary surface can yield higher performance. With many drivers there is no difference in performance between overlay and primary when screen is in 16 bpp mode; and primary is using 1/2 of overlay bandwidth when screen is in 8bpp mode. In general, it is only with some hardware analyzers that one can see difference between overlay vs. primary surface support. I).VGA Compatibility 1) Overlay mode of those VGA are not supported by graphics controller. S3 Vision 968 Matrox Millenium MGA 64bit Matrox Millenium II MGA 2164 Matrox Mystique PowerDesk MGA 64bit Matrox Mystique II AGP PowerDesk MGA 64bit 2) Those of graphics drivers are not Direct Draw compliant. Cirrus Logic CL-GD5434-HC-D 3) Those of poor quality overlay mode video, please change another VGA. Cirrus Logic CL-GD5464-HC-A Cirrus Logic CL-GD5465-HC-A 4) Those of VGA with the bandwidth problem, run in 16bit mode only. ATI 264GT S3 Vision 325 Virge(DX/GX) 5) Those of VGA chipsets do not support color key natively. Tseng VGA Matrox Millenium G200 6) Those of S3 VGA need to modify the registry key value. Please set VGA run in 16bit mode for S3 775 only. S3 Vision 775 Trio64V2(DX/GX) S3 Savage 3D 7) Those of graphics cards run on BT848 driver version V2.30.40 only. You have to get this driver to prevent PC hanged. Trident 3D Image 9750 Trident 3D Image 9850 8) Those of graphics cards come with color bar noise. You have to get the new VGA driver from your VGA vendor. Trident 3D Image 9880 9) Those AGP cards work with TV application V3.08 or later. Please select VGA chipset in TVCFG.EXE System Configuration Utility. ATI Rage Turbo/ IIC Chromatic MPACT II Intel i740 RIVA 128 (Primary overlay service only) RIVA 128 ZX (Primary overlay service only) RIVA TNT (TNT Driver V4.10.01.0037 or 4.10.01.0121 and later) S3 86C365 Trio 3D S3 86C362 LC2X S3 Savage 3D SiS 6326 (Some run in 640x480 only) VooDoo Banshee (Must update 3Dfx drivers) 10) Those of graphics cards listed below support primary service only. You have to get the new VGA card driver from your VGA vendor to support overlay overlay service. The only solution is to watch TV in primary service mode only. The OSD and the full screen functions are disabled, but you can check the FORCE FULL SCREEN parameter in video setting dialog to force DirectX driver change mode to 640x480 and full screen. 3D Labs Permedia II RIVA 128 RIVA 128 ZX RIVA TNT RIVA TNT2 VooDoo Banshee 11) Those of graphics cards listed below may halt PC. You have to get the new VGA card from your VGA vendor. SiS 620 Chipset embedded VGA There is an internal path inside SiS620 which is provided to perform the transactions from PCI bus to GUI bus, wherein the video capture card is resided on PCI bus while the graphic accelerator is integrated behind the internal GUI bus. It should be emphasized that the internal path from PCI bus to GUI bus just supports to perform memory write transactions in unique direction. The temporary solution is not to display video at OVERLAP mode. The video capture function can still be used in Non-Overlap mode. This bug has been fixed on 620 A2. The only solution is to watch TV in preview mode only. 12) Those VGA cards are not listed. The VGA cards that not listed above do not mean they can not work with Brooktree BT848/878. Be sure that the VGA card supports DirectX 5.0 or higher and the overlay service is a must. 13) To make Brooktree BT848/878 work with the new released AGP cards, please run TVCFG.EXE and set the chipset name of the VGA card. TVCFG will correct some registry key that make BT848/878 work well. The OSD function will be limited if the VGA does not support overlay service or color key. Please set the VGA to high color (16 bit) if you get poor video display image with magenta background or bar, colorkey. Click or move the video display windows or set PREVIEW mode then switch back to OVERLAY mode again if you get magenta colorkey. The screen is blank for some VGA when they wake up from sleep mode. The problem mentioned is not answered by Brooktree driver, it is because of the VGA DirectX driver. You have to update VGA driver. J).Sound Card Compatibility This sound card listed below does not work with BT878/879 PCI audio and some games such as FORSAKEN, get driver update from SoundBlaster at http://www.SoundBlaster.com The problem is because of the Master Volume control is limited. Creative PCI32 Ensoniq AudioPCI 5000, Creative Technology Ltd. This sound card listed below comes with error mixer description in driver and you have to update driver : CMI 8330, C-Media Inc. This sound card listed below may cause horizontal noise on video window and you have to update driver or change another more compatible one : S3 Sonic Vibes, S3 86C617 sound chip. K).Sound Card Installation and Troubleshooting The sound card mixer will mix all the checked audio sources and the VFW recording service will capture audio and video as AVI file. The TV card audio out is not emphasized, you have to connect it to an active loud speaker. <<< Playback >>> 1. Please click the sound card mixer on the right corner of task bar. 2. Click the "Options" of the pop-up menu, select the "Property". 3. Select the "Playback" and show the LINE-IN signal volume control. 4. Click "Volume Up" on the TV control panel and see if the volume of LINE-IN of the mixer should go higher. 5. Click "Mute" on the TV control panel and see if the LINE-IN MUTE of the mixer should be checked, click again to un-mute. 6. If step (4) or (5) fail, update your sound card drivers because of this card/driver is not Windows Sound System compatible product. 7. Ckech the "Mute" box and see if the volume muted. 8. Unckech the "Mute" box and drag the volume control of LINE-IN and see if the volume louder. 9. If step (7) or (8) fail, the sound card is out of order. 10. If you still hear nothing, just connect the loud speaker to the audio output of TV card, adjust the suitable volume and the output should be clear. If nothing at all, the TV card's audio output is out of order, change another one from your local dealer. <<< Enable Audio Recording >>> The sound card is a must for video capture and video conference functions. TV capture runs with the sound card that with LINE-IN for TV AUDIO cord. You have to connect the TV audio card to the LINE-IN of your sound card. You have to enable audio via Video Setup (Capture Settings) ---> Capture Parameters ---> Enable Audio <<< Recording >>> For some users report that no audio in the captured file even the "Capture Audio" is set in the "Capture Parameters" dialog. 1. Please click the sound card mixer on the right corner of task bar. 2. Click the "Options" of the pop-up menu, select the "Property". 3. Select the "Recording" and show the LINE-IN signal volume control. 4. Check the "Select" box and drag the proper LINE-IN level. 5. Click the "Options" of the pop-up menu, select the "Property". 6. Select the "Playback" and show the LINE-IN signal volume control. 7. Click on "OK" to exit. L).Video Display With Noise or Grayed Please adjust the video standard (NTSC, PAL or SECAM) if you get noise only on the upper side of the video display window. This is because the BT848/878 set NTSC to be the default video standard. 1. Run TVCFG again to select the location you are and the chipset name of the VGA card you installed in the PC. 2. Click the VIDEO/CAPTURE SETTING dialog and select VIDEO SOURCE, set the video standard matching TV source connected. 3. Here you get video now. Otherwise, exit TV application and power off PC then unplug TV card to check the crystal frequency is 28 or 35MHz. For most of the TV cards, it should be 28MHz but for some PAL system, it may be 35MHz according to the TV card designed. Plug the TV card in the slot you unplug it and turn PC on again. Run REGEDIT.EXE from the task bar and press F3 search for "RefFreq" and it should be located in one of the following registry key : HKEY_CLASSES_ROOT\\Bt848\\RefFreq HKEY_CLASSES_ROOT\\SOFTWARE\\Classes\\Bt848\\RefFreq HKEY_LOCAL_MACHINE\\Software\\Classes\\Bt848\\RefFreq HKEY_LOCAL_MACHINE\\Software\\Brooktree\\Video\\RefFreq Edit the value and make sure the value is identical to what you see on the TV card. F3 again and again to find anothers, edit them all. Run TV application again and you should get clear image, otherwise, the TV card may be out of order. 4. To avoid the interference between electrics, a cable spliter is a must. This spliter should be in fornt of the VCR. A signal emphasizer is a must if you split TV cable into 4 or more devices. Weak signal causes horizontal wave on screen. TV.CABLE ------> SPLITER +---> A) VCR ----------------> TV +---> B) PC Capture Card ---> VGA 5. If you uninstall the application but not the driver and reinstall application again, you must run TVCFG first to configure the location and VGA card first, otherwise the video format parameter existed may cause noise in video display window. M).Profiles for TV / FM Application 1. The following are profiles that used by TV application TSCTV.INI : TV application default setting You may remove all sections GRAPPLER.INI : TV system configuration file You may remove [Country] section, and TV application will call TVCFG.EXE to select the location next time. 2. The following are profiles that used by TV application TSCFM.INI : FM application default setting You may remove [FM] section which keeps the volume and default frequency settings. 3. The following are profiles that used by TV/FM application TSCTVFM.INI : TV/FM hardware configuration file. Please do not modify any item, factory only. N).Capture BMP and AVI File When capture frame as BMP/JPEG or copy to clipboard, the video display window may flush in a second and the colorkey (magenta background) shown. This will avoid the capture frame errors (Brooktree driver). The captured BMP size is the video size set in VIDEO FORMAT dialog. When running the AVI capture, select Brooktree ProSumer as the compression format by clicking on VIDEO/CAPTURE SETTING and the select VIDEO COMPRESSION. This will minimize capture errors. Most of the video compress engines take time to compress the captured AVI file even the time limit is set and always timeout. The selected compression format is not memorized because of the VFW limitation, you have to reset it again when application restarts. The AVI capturing process will stop only if Timeout Enable capture Time limit set in capture parameters, Keyboard <Esc>, <SPACE> or <F8> set in capture parameters, Mouse <Left> or <Right> button set in capture parameters. The ALLOCATE SPACE function allocates a continuous block of disk space for AVI capturing, not to set the captured AVI file size. The SAVE AS saved AVI file will report the actural size it occupied. The BTVfW driver supports the overlay mode. However the overlay mode may not display live video or video streaming (which is typically used in videoconferencing applications) during video capture. If you wish to see live video during video capture, select preview mode. Be sure to set proper video format to get the best quality. O).Rockwell QuartzSight Digital Camera Few of the TV card makers bundle Rockwell QuartzSight Digital Camera. Please select camera input only in the VIDEO SOURCE dialog because the Rockwell does not implement 32bit codes for digital camera. There is only one way to switch between analog and diaital inputs. The analog input such as Air, Cable, Composite and SVHS could be toggled or clicken to select but the digital camera such as Rockwell QuartzSight, Silicon Vision 512N or Logitech VideoMan is selected only in the VIDEO SOURCE dialog. Once digital camera input is selected, you must reselect the analog input form VIDEO SOURCE dialog if you want. Then you can click to select the analog video sources from desktop panel. The Philips camera with 8-pin mini-din connector is analog input indeed. P).Remote Controller Most of the TV cards come with remote controller. Please open the TV SETUP dialog to DISABLE REMOTE CONTROLLER if the remote controller is not tightly connected to the remote input connector and close the application. Try to connect the remote controller tightly, run application again and ENABLE REMOTE CONTROLLER to see if the reomte controller works. The 38KHz remote controller may malfunction if a 40KHz PL light is around. Please move the PL light away and try again. You may need to disable the remote temporarily and restart your PC again to make remote controller take effect. Q).Help file The TV application contains online help file which can be invoked via hot key or button on desktop in most Windows 95/98. This function may not work because of the unknown problem of Windows 98 and caused in other applications as well. Please run from the task bar instead if this function is not implemented. We try to call WINHLP32 to open the online help file instead and that will not close the help file when exit. You have to close it yourself. R).TV System Configuration TV System Configuration (TVCFG.EXE) is for the user to configure the TV system and multilingualism, where Location : Where user locates, and TV system is set automatically. VGA : The VGA chipset is, and driver performance is improved. Language : Select the multilingual hints on application control panel. You may select the "User defined" language and show them on the control panel. The default message is shown as American English, please edit the user message file (TVMSGUSR.INI) located in the installed directory, save and exit then run "TV System Configuration" (TVCFG.EXE) again and select "User Defined" language and click on "OK" to go. S).TV Uninstaller TV Uninstaller (TVUNINST.EXE) is for the user to uninstall the applications and drivers. Please copy your original information file TVCFG.BIN before uninstallation and copy this file to the application installed directory after updating. Please download the file TVUNINST.EXE because it may not deliveried in the previous version CD-ROM released and copy this file in original installed directory. For the sake of program architecture, please uninstall applications first and drivers next. Be sure to restart the computer to install drivers and then applications again. T).Closed Caption Support A frame of video is composed of 525 lines for NTSC and 625 for PAL/SECAM. The video image is contained in the odd and even fields within lines 21 to 263 and lines 283 to 525 respectively. Each field of video also contains a region for vertical synchronization (lines 1 ~ 9 and 260 ~ 272) as well as a region which can contain non-video ancillary data refered as the Vertical Blanking Interval, VBI (lines 10 ~ 20 and 272 ~ 282). The BT848 and BT878 are able to capture VBI data and store it in the host memory for the later processing by the VBI decorder driver. The start of VBI data capture is set by the VBI_HDelay in registry key, which is set to 0x07 for NTSC and 0x19 for PAL (see Cebra below). The Closed Caption is functional only if the video is 320x240 or larger. Could we enable closed caption and run Cebra Teletext simultaneously ? No. Only one VBI client may connect to the VBI driver at any one time. This includes the Brooktree internal Closed Caption decoder. Some users may watch TV in PAL system but VHS/LD in NTSC system. It fails because both C.C. driver and Cebra Teletext applet both get the VBI_HDelay registry key but for different values. And even more, PC will hung if the Cebra applet runs and user enables C.C. driver. To enable Closed Caption, we have to exit CEBRA Teletext first. How can we do if we want to watch TV in PAL system but VHS/LD in NTSC ? Please open VIDEO/CAPTURE SETTING dialog and select VIDEO SOURCE dialog then click on the COMPOSITE or SVHS to locate the video source and drag the VIDEO STANDARD to select NTSC-M and OK to close the dialog. Now you can see the video data in the display window. To enable C.C., select the VIDEO DISPLAY dialog then check to enable the Closed Caption channel 1 and you see text now. You need to exit from application and restart again if closed caption text is not overlaid on the video display window. The drivers need to run again to make the new settings take effect. To watch TV with Cebra Teletext, you have to disable C.C. first and select VIDEO SOURCE dialog then click on the TV to locate the video source and drag the VIDEO STANDARD to select PAL and click OK to exit. Now you can watch TV again. Closed caption text will show in a second only for some imcompatible VGA cards which run in primary overlay mode instead of overlay overlay mode. There exists one bug in Brooktree's Closed Caption driver BT84XCC.DLL or BTCC32.DLL or BTCC.DLL thak makes resource leakage every time you resize the video window or change the video mode and then the PC may locked up. If you do not use Closed Caption function (NTSC-M only), just erase the file in the windows system directory and that solves the problem. U).Cebra Teletext Support Most of the TV card makers bundle Cebra TELETEXT application for PAL. Ask your local supplier for more Teletext informations. For Cebra Teletext updating, please download http://www.cebra.dk/32bit/setup.exe We use Cebra Teletext program in London and find it looses two columns information to the right. The loss of characters to the right can be fixed by running TVCFG, TV system congiguration. If the TV program version is V3.02 or higher, try to correct this by setting the parameters in the file located in the Windows directory and run TVCFG.EXE, set the location and the reboot. <Windows directory>\TSCTVFM.INI [TV] VBIDELAY=PAL ; This will set VBIDELAY to 0x19 for all but NTSC VBIDELAY=UK ; This will set VBIDELAY to 0x19 only for the UK only VBIDELAY=PAL-I ; This will set VBIDELAY to 0x19 only for the PAL-I only VBIDELAY= ; Do nothing for Cebra The Hungarian problem is caused by absence of these characters from the (quite small) 7-bit teletext character set. Can you try a download from http://www.cebra.dk/32bit/setup.exe and see if that works better. Here Cebra are supporting the WST standard for character replacements, and maybe this is enough for the Hungarian market. The application implements Closed Caption and Teletext in one button. The application will check the TV format/location when it starts and Closed Caption (C.C.) shown if the NTSC system is set in TVCFG and Cebra Teletext (Text) shown if the PAL system is set. The VIDEO STANDARD in VIDEO SOURCE is nothing concerning to the button, it affects the VBI_HDelay for C.C. and Cebra Teletext only. V).Intel Intercast Support The TV card makers listed above support Intel Intercast for Internet and TV service together. Most of the TV card makers do not bundle INTEL INTERCAST application. You may download InterCast form INTEL http://www.intel.com website. W).Window Driver Module (WDM) Support There are WDM beta drivers for Windows 98 WebTV (U.S. Version only). There will be WDM drivers for Windows 2000 (known as NT 5.0). Current WDM driver is for Windows 98 English WebTV only, neither video capturing nor frame grabing. For the sake of both watching TV and capturing video, please install VxD driver for Windows 95 / 98. The WDM driver supports Windows 98 English Wavetop utility. Some users complain that they can not make Wavetop run with BT878 WDM driver. We get the message from Broketree, DID, that customers should get the latest version of Wavetop software from WavePhore to make it run with BT878 WDM. It is not the problem of the BT878 WDM driver. Please update Wavetop service from http://www.wavetop.net X).Video mail with Real Player Support RealNetworks is the pioneer and established market leader in streaming media technology on the Internet. RealNetworks is helping transform the Internet into the next mass medium by making real-time, or streaming, Internet broadcasting possible and profitable. In only four years, RealNetworks software systems have become by far the most pervasive method of streaming media on the Internet and intranets. The captured AVI file comes with terrible size and is not suitable for video mail over Internet or telecommunication. However, you may encode AVI into the RealMedia file format for Real Player G2 with RealEncoder V5.1 that make Video Mail come true. The RealEncoder V5.1 is a free download application from RealNetworks that converts captured AVI video files into the RealMedia file format. The converted RealVideo files are available for RealPlayer V5.00 and the new RealPlayer G2. You may inform your friends to download the newest RealPlayer if they do not install Real Player from http://www.real.com Please specify encode method according to the Internet connecting way. For example, set [56K Video Dial-Up Modem, Voice], RealEncoder converts a 17,434 KB non-compressed AVI file into a 202 KB RealVideo file for 30 secs smooth video and audio with little quality drawback in video but save 98.84 % of transmission time. Y).Linux support BTTV - BT848 frame grabber driver Copyright (C) 1996,97,98 Ralph Metzler (rjkm@thp.uni-koeln.de) & Marcus Metzler (mocm@thp.uni-koeln.de) according to the GNU GPL in the file COPYING. BTTV is a device driver for frame grabber cards using the Bt848 family of video decoder chips. Among those are the Bt848, Bt848A, Bt849, Bt878 and Bt879. The only major differences between the cards by different manufacturers are the types of tuners and extra components on the boards. E.g., some cards by Hauppauge have an additional Videotext decoder and/or sound decoder chip. Only some of these additional components are supported by bttv. Also type (Composite or S-Video) and number of inputs differ. Other Brooktree chips (e.g. the Bt829) or chips by other manufacturers (Philips, Zoran, ...) are NOT supported by bttv. But e.g. the xtvscreen application should work with the IOMEGA BUZ driver by Dave Perks. You can use several cards at the same time. Interrupts can be shared with other Bt848 cards or any other drivers which allow it. If you have problems sharing interrupts please fix the other driver with the same interrupt. Bttv is NOT the problem! The (arbitrary) maximum number of cards is 4 but can be adjusted by changing BTTV_MAX at the beginning of bttv.c if you need more. (But which board has more than 4 PCI slots plus 1 for the VGA card? OK, some boards like the ASUS P5A have 4PCI+1AGP) Bttv is a standard component of all newer 2.1.x kernels. This distribution additionally tries to support 2.0.x kernels and includes all other changes and improvements which did not make it into the kernel version yet. It also includes versions of videodev.c, i2.c, tuner.c and others which are the same as in the latest 2.1.x kernel but with 2.0.x support. A kernel version >=2.0.35 is recommended. Note that it is in NO way guaranteed to work with 2.0.x kernels but adaptation to 2.0.x should be easier than starting from the version in 2.1.x kernels. There also might be newer features contributed by other persons in the kernel releases which did not make it in this separate release of bttv yet. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Although bttv is now used and tested by many people it still might crash your computer! Take all precautions to avoid data loss until you are certain bttv runs on your setup without problems. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! The latest version of bttv can be found at: http://www.thp.uni-koeln.de/~rjkm/linux/bttv.html Z).More Technical Support Please update drivers and applications from listed above respectively. If you need to program the Brooktree video capture card yourself, contact your Rockwell Semiconductor System local dealer for details.Download Driver Pack
