Helix DNA for Android


• 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

Q: The problem?


Helix Client SDK for Android A: ?

• 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.
