Videum AV is a high-performance video and audio capture board and software solution that allows you to turn your PC into a streaming Internet video server using Cisco IP/TV streaming video server.
Videum AV easily inserts into an available PCI slot. Videum AV includes software that allows you to:
Videum captures in Windows AVI file format, audio in Windows WAV audio format and still images in Windows BMP or JPEG file formats. In addition, a microphone input and stereo speaker output jacks are provided. Additional information is given in Appendix B, "Videum Hardware Specifications."
Videum AV and VO Capture Solutions
The Videum AV capture card is powered by Winnov's own multimedia processing chip, WAVI. WAVI is a result of several years of research and development and provides extra functionality allowing software capture features to go far beyond other capture products. Videum AV includes both audio and video capabilities.
WAVI enables digital audio and video capture that is synchronized at capture time. These solutions also include a composite video input, and S-Video input, as well as Winnov's Multimedia Extension Connector (MXC) for a color video camera that ships with Winnov's Videum Conference Pro video conferencing kit.
This section contains hardware, connector, and pinout specifications for Videum AV.

Videum products support the following audio formats:
Each of the Videum applications is accessed through the Winnov Videum group (Figure 1-1) and is described in the following sections.
The Videum menu contains access to all of the Videum software components. The software allows you to configure your system, set video and audio characteristics, and capture audio, video, and still images.
The Audio Panel (Figure 1-2) allows you to control the audio input and output mix.
For more information about using the Audio Panel, see the"Setting Audio Characteristics" section.
Videum Capture allows you to quickly capture and view video and audio clips and still images and view or play them back right away. Once you like a clip, the captured audio and video can be streamed by Cisco IP/TV. Videum Capture is shown in Figure 1-3.
For more information about using Videum Capture, see the chapter "Capturing Audio, Video, and Images with Videum Capture."
The Videum Configure application (Figure 1-4) allows you to set audio and video properties for the Videum Capture applet and all other video applications.
You may have a More button on your configure window depending on the hardware and software you have installed. This button allows you to set additional video characteristics. For more information about using Videum Configure, see the chapter "Capturing Audio, Video, and Images with Videum Capture."
To access help, choose Contents or Help from the Help menu in any of the Videum applications or choose Videum Help from the Videum menu. Context-sensitive help is also available by clicking the Help button in most dialog boxes or selecting a window and pressing the F1 key.
