Osprey-845e 4 Channel SDI (4ch SD/HD or 2ch 3G) card with Digital Simulstream
The ViewCast Osprey 845e 4-Channel SDI Capture Card is a video and embedded audio capture card for Windows and Linux. It features four SDI inputs that can simultaneously capture up to four channels of 1.5 Gbps HD-SDI video, or two channels of 3G-SDI video. In addition it can capture four stereo pairs (eight channels) of SDI-embedded audio per video source.
The Osprey 845e is a versatile card that can be used for a wide range of applications, such as recording multiple streams of video to a computer or live streaming multi-camera productions. For Windows users, the card features drivers that expose it to the Microsoft DirectShow API, Windows' media device interface framework. This means that card is compatible with most Windows-based software that is capable of capturing or streaming video.
For Linux users, there are a wide range of Open Source software options available via the Linux distribution's package manager or as source code from GitHub and other repositories. In addition, users looking for custom solutions can develop their own software using the software developer kit (SDK), which can tailored for unique applications.
The Osprey 845e also features SimulStream. This driver enhancement provides the ability to feed multiple encoding applications at the same time. The most notable benefit of this feature is the ability to encode the same video source at different frame rates and resolutions to support a wider range of devices and Internet connection speeds, something encoding applications often lack the ability to do on their own.
Because of the high data-rates involved in multi-channel video capture, it is important to consider the computer that will be used. While the exact system requirements will vary depending on the specific capture or streaming software that will be used, a quad-processor or better workstation computer with a direct- or North Bridge-connected x8 PCIe slot will likely be required.
