Power efficient M.2 capture cards for OEM developers

The Eco Capture Dual HDMI M.2s are now being shipped - the first of three models unveiled earlier this summer in Magewell's Eco Capture family of video capture cards for OEM developers. A fourth configuration has been announced which the company claims provides quad-channel capture density in an ultra-compact form factor.

Designed for use in small and embedded systems where full-sized PCIe slots are not available, the first four Eco Capture models feature a high speed PCIe 2.0 bus interface with an M.2 connector. Measuring 22 x 80mm, the Eco Capture cards' power consumption is said to be 30 to 70% lower than the company's Pro Capture cards with similar input signal connectivity and channel count.

According to the company, the Eco Capture HDMI 4K M.2 captures one channel of 4K video up to 4096x2160 at 30frames/s via HDMI, while the dual-channel Eco Capture Dual HDMI M.2 and Eco Capture Dual SDI M.2 capture HD or 2K video up to 1080p60 over HDMI or SDI interfaces, respectively.

The newest addition to the product line, the Eco Capture Quad SDI M.2, is said to double the latter offering's channel density, capturing four concurrent HD or 2K SDI source signals.

The M.2 Eco Capture models are available with drivers for Windows and Linux operating systems. OS-native capture APIs are supported, including DirectShow, DirectKS, V4L2 and ALSA. Stream replication enables each input channel to be delivered to multiple software applications simultaneously with identical capture parameters.

The company claims FPGA-based video processing provides high quality up/down/cross-scaling, picture controls and colour space conversion without tasking the host system CPU, while additional processes are performed by software. All four models also support up to eight channels of embedded audio per input.
