DVEO to offer four-channel HD-SDI input card with automatic standards detection

DVEO will showcase a four-channel HD-SDI PCIe capture card with automatic standards detection for the various HD formats at IBC in Amsterdam.

The HD-SDI Master Quad/i PCIe simultaneously receives up to four independent real-time HD-SDI streams and stores them in a PC workstation or video server. The card is designed for HD video encoding, post-production processing, electronic newsgathering (ENG), and storing HD video for editing applications. The total bit rate is almost 6Gb/s, due to the high bandwidth of PCI Express.

The HD-SDI Master Quad/i features automatic standards detection. The firmware on the card does all the work in converting to the different HD-SDI formats to minimize the use of host CPU cycles. Supported video formats include 1080i, 1080p and 720p.

Users may select either 1.485Gb/s or 1.4835 (1.485/1.001) Gb/s for the top and/or the bottom two channels, in order to support video formats defined for true 60Hz rates as well as those defined for the 59.94Hz rates commonly used in North America. Onboard memory and a proprietary firmware design are used to buffer the inputs to give low system latency.

The HD-SDI Master Quad/i includes driver and API support for Windows and Linux, plus DirectShow filter support. Additional features include automatic cable equalization and embedded audio extraction (up to eight channels). The card also supports deinterlacing in hardware and can monitor the incoming stream for CRC errors.

The Best Deconstruction of a 4K Shoot You'll Ever Read
With higher resolutions and larger HD screens, wide shots using very wide lenses can be a problem because they allow viewers to see that infinity doesn’t quite resolve into perfect sharpness.
