7. Q: The problem?
• Broadcaster wants to provide the same iOS media service to Android
and iPhone, iPad (objective simplify delivery and reduce encoder costs)
• Android native media player doesn’t support HLS. (Android 2.x – the most
popular OS versions – supports RTSP only)
• Android 3.0 and 4.0 do support HLS but
• not same as iOS player quality – slow, poor performance, bugs
• proprietary DRM – WideVine only
• Broadcaster wants a reliable media player including open choice DRM
A: ? Helix Client SDK for Android

8. Helix SDK overview
• HTTP Live Streaming over the air (OTA) enabler for
Android OS devices.
• Ready to go development package for
broadcasters, service providers, content
providers and mobile communication
providers.
• Native media players in Android devices
don’t have the features service providers
require. Helix Client SDK is the best
engine to support HTTP Live Streaming
and MPEG-DASH on top of customer
application.
• Fully compatible with iOS and MPEG-
DASH device streaming, supports widest
range of chipsets with high quality
playback.

9. Why use Helix SDK? Helix vs. Android
Helix Android
Fragmented across OEM device firmware and
Uniform and consistent implementation
chipsets
Available on Android 2.2 and above OS versions Available only from Android 3.0 and above
High quality – superior audio/video sync, Low quality – start up latency, late seeking,
smoother/faster seeking, low start up latency broken audio/video sync,
Highly interoperable with all leading encoders Lower interoperability
DRM solution available (Verimatrix / PlayReady) No default DRM integration (2.2/2.3/3.x)
Proven solutions – success references, pre-
Untested solution
ported devices
