Charest Communications Research Centre Canada Disruptive innovation in the mobile space ● Software platforms ● Application driven ● 50.000 iPhone applications in one year ● Dozens of 3G Internet radio applications ● Many FREE applications ● Independent developer and user innovation (Internet-like) ● Trend towards open source (Android, Symbian,...) ● Verticalisation of platforms less than 10 major mobile software platforms ● Mobile Application Stores (MAS) Developers: upload / sell / upgrade Users: download / buy / remove / upgrade No mass-market handheld with broadcast support yet ● Some closed platforms exist ● Can not be programmed by independent developers ● Limited potential for innovation A PLATFORM IS NEEDED: OPENMOKAST

THE OPENMOKAST OPEN SOURCE FRAMEWORK: TOWARDS USER INNOVATION IN THE MOBILE BROADCASTING APPLICATION SPACE OPENMOKAST FRAMEWORK OPEN MObile "broadKASTing". ● Project launched by CRC in 2007 ● Support for DAB/DMB technology ● First prototype and public demo at IBC 2008 ● Open sourced in 2009 (GPL) PROTOTYPE Objectives: ● Catalyse innovation in the Broadcasting to Handhelds (BTH) space ● Openmoko software framework ● Foster chipset integration through pre-existing applications ● Neo FreeRunner smart phone (FIC) ● Foster end-user innovation ● M-Tech USB DAB receiver Technical: Supported applications: ● Modular architecture to support many devices and output types (plugins) ● DAB MP2 audio ● Modules managed by a core component ● DAB+ HE-AACv2 ● D-Bus and Telnet APIs available to third party applications ● CELT audio ● Enables control of receiving device ● MOT Slideshow (DReaM project) ● Enables access to application ● Journaline

THE OPENMOKAST OPEN SOURCE FRAMEWORK: TOWARDS USER INNOVATION IN THE MOBILE BROADCASTING APPLICATION SPACE OPENMOKAST ON ANDROID Openmokast Player Openmokast Player on on T-Mobile G1 Android Market (MAS) Android: ● SDK available for free (Nov. 2007) ● User applications are in Java (Dalvik) ● Applications existed before devices (contest, ...) ● Android Open Source Project (Nov. 2008) ● Android port for FreeRunner exists ● Native Development Kit (NDK, July 2009) C and C++ code can be integrated through JNI Prototype: ● Android Developer Phone (G1) ● Openmokast application on MAS (Android Market) ● DAB sub-channels through WiFi Demo Applications: ● Real-time CELT audio decoding and playback ● Real-time Slideshow decoding (C code from DReaM) Openmokast on Android Current System Architecture CONCLUSIONS ● Clear mobile trend: software applications ● Can be done for broadcast applications ● Embedded device featuring bcast chipset still needed ● Many open platforms available for initial work ● Openmokast player available through Android Market ● Openmokast available for free under GPL license ● Openmokast could be used as a common basis ANY PLANS FOR A COMMERCIAL ANDROID DAB/DMB PHONE?
