Video Capture Videoconferencing systems require a video capture system. A video capture system includes a video camera, typically an NTSC or PAL posite video camera, and a video capture card, either an ISA bus or PCI bus capture card. Usually, these are not provided preinstalled on the PC. Thus, installation of a videoconferencing system on a PC almost always involves installation of a video capture card and camera. Usually, the video capture hardware is provided with the video conferencing applications. Installing a video capture card requires opening the PC case and inserting the card in an available ISA or PCI slot as available. Seating problems may occur, where the card appears to be seated in the slot but the electrical contact is imperfect or broken. In this case, the software will report a failure to find the video capture card, or other symptoms may occur. The video capture card usually has either a posite video input or a posite and an SVideo input. The camera must be attached to this input. In some cases, the electrical connection will be imperfect even though the cables appear plugged in. In these cases, the installer must manipulate the cables until a working connection is established. Some ISA video capture cards require selection of the IRQ interrupts through jumpers on the ISA board, although this is being less mon. Other ISA cards may be configured through software. Plug and Play pliant ISA and PCI cards may sometimes experience resource conflicts due to bugs in the Plug and Play implementations. Video capture is handled through Video for Windows drivers. The most recent version of the 16 bit Video for Windows for Windows and Windows for Workgroups is Video for Windows . A version of Video for Windows with 32 bit video pressors and unknown other differences from Video for Windows ships with Windows 95. This Video for Windows (95) provides the video capture functions in Windows 95. ActiveMovie , which ships with Windows 95 OEM Service Release 2 (OSR2) and can be installed on earlier releases of Windows 95, does not provide any support for video capture. The video capture card installation software should install a Video for Windows video capture driver. This driver is identified by the line: MSVIDEO= in the [drivers] section of the Microsoft Windows file. Things To Do for Video Capture Problems ? Reboot. ? Check for IRQ or other resource conflict. ?
