Device Information / Hardware

The Broadcom 97425 is a powerful dual core MIPS set-top-box reference design. The
hardware is capable of running QtQuick2/SceneGraph. Broadcom provides an optimized
version of DirectFB for 2D graphics, input and image decoding. The multimedia architecture
is based on GStreamer. Broadcom provides pipeline elements to access their hardware.

Software provided by Broadcom

Broadcom provides customers with the AppLibs and RefSW. The last tested version is 20111222
for the RefSW 20111222. The rockford 3D library needs to link to DirectFB to avoid
missing symbols when loading the DirectFB/QPA plugin. The patch was provided to Broadcom and
should be included in future versions.
