Ixonos today announced an embedded Linux BSP (board support package) for security cameras and other small-footprint devices requiring low latency, full-HD video streaming. The BSP supports designs based on TI’s DaVinci DM8148 digital media processor.

The Ixonos BSP can guarantee latencies as low as 257ms for full HD 1080p30 A/V streaming, according to product specialist Martin Lund. The secret sauce on the hardware side is a TI DaVinci DM8148 digital media processor SoC (system-on-chip), which integrates a dual-core C674x floating-point VLIW DSP along with an ARM Cortex-A8 CPU (see block diagram, below).

On the software side, the Ixonos BSP makes use of Gstreamer 1.0, an open-source multimedia framework, as the streaming backend.

“Based on our understanding, this is the fastest video streaming on a low power embedded system. In our solution, we are really optimizing how the chipset is running,” says Lund.

Ixonos says its “lightweight” embedded Linux BSP stack offers fast boot time is “easily extendible” for any type of Embedded Linux application, and runs on boards from several leading chipset manufacturers.
