This document discusses STMicroelectronics' work on MPEG DASH implementations. ST is developing DASH clients for the GStreamer multimedia framework on Linux and the Android media framework. For GStreamer, ST has integrated a DASH receiver and is working on features like audio/video synchronization and integration with HTML5 players. For Android, ST has extended the native Apple HLS implementation to support MPEG2-TS profiles. Both projects aim to benchmark performance and compliance on ST platforms and integrate DRM frameworks for secure streaming.
