Optimizing the HD radio and DAB experience Optimizing the HD radio and DAB experience Presentation Transcript

  • HD radio and DAB Optimizing the digital radio experience Nicolas Hans, [email_address] For more information, visit www.dalet.com
  •  
  • digital radio puts content into context
  • station information service Station branding program associated data program titles, artist, songs… advanced application services traffic information, weather information, city guides…
  • producing enhanced radio programming is a challenge
  • provide compelling content minimize production costs generate new revenue streams
  • lessons learned from digital radio experiences around the world DAB, DRM, interactive TV, Webcasting, World Space, XM Satellite Radio…
  • five steps to producing enhanced radio programming
  • build a digital media library. step 1
  • Digital Media Library interactive services archives programs studios news traffic
  • Case Study: Satellite Music Australia
    • Founded in 1996, SMA provides multi-channel audio entertainment to cable and satellite TV operators:
      • Austar Network (400 000 homes)
      • Foxtel (400 000 homes)
      • Foxtel Digital (100 000 homes)
    • Subscription based musical background to commercial outlets.
    • Bespoke channels for large retailers: national programs with splits; advertising as additional revenue stream.
  • SMA built a digital music factory to centralcast its operations.
  • The SMA music library contains over 650,000 titles with associated data.
  • Enhanced radio programming at SMA
    • Channels broadcast over digital TV networks provide enhanced radio services:
      • Electronic Program Guide (EPG) to 30 channels.
      • PAD information of playing song including title, artist, record label.
      • Music news service updated twice a day.
      • “ Gig guide” of coming concerts.
  • SMA provides listeners with an Electronic Program Guide.
  • An Electronic Program Guide (EPG) lists available music channels.
  • Additional services including music news updated twice a day are provided.
  • Music news provides last minute information regarding the music scene.
  • Listeners/viewers can select the one they are interested in...
  • ... and get details on the gig they want to attend.
  • How it works… Audio files PAD (metadata) Open TV Application Generator Open TV Application Server XML data stream MPEG-1 Layer 2 AES/EBU DVB-MPEG Encoder DVB transport stream Application code and static data Dalet OnAIr Server Dalet OnAir Now! plug-in Synchronization of associated data is ensured by the Dalet broadcast server. DVB Multiplexer
  • re-engineer the production workflow to collect PAD. step 2
  • Plan Ingest Produce Schedule Broadcast Archive Multicast
  • traditional metadata ingest points Plan Ingest Produce Schedule Broadcast Archive Multicast
  • producing relevant Program Associated Data requires that metadata be captured at every step of the workflow . Plan Ingest Produce Schedule Broadcast Archive Multicast
  • move to a template-based production environment. Step 3
  • The view of the metadata associated to an asset can be made contextual…
  • … and rich media associated to titles so as to provide enhanced radio programming.
  • As a result, additional metadata can be inserted at every step of the workflow.
  • provide compelling content minimize production costs generate new revenue streams
  • drive interaction to generate revenue streams. step 4
  • Kids today have a remote control in one hand, and a mobile phone in the other… Rick Solomon, Co-founder and Managing Director of Satellite Music Australia
  • Nokia Visual Radio
    • Mobile phones with FM receivers that can receive PAD over GPRS/3G data channel:
      • Audio is traditional FM
      • PAD is IP based using GPRS connection
      • Return line paves way to MP3 on-line sales, e-commerce applications.
  • Over a billion SMS text messages are sent around the world each day. Premium charged SMS numbers open up new opportunities for revenue.
  •  
  • 900 000 USD a year of revenue! 5 500 SMS messages a day
  • export programming to other media platforms step 5
  • An interactive music TV platform Music clips and programs are ingest in MPEG-2 Long GOP on the Omneon server (1) thanks to a DaletPlus Video Recorder for Omneon workstation (2). A Windows Media low bit-rate proxy file of each clip is generated by a DaletPlus Media Converter (3) and associated as metadata to each recorded asset tracked by the DaletPlus Media Library content catalogue (4). Using DaletPlus Media Library workstations (5) or a web browser connected to DaletPlus InterWeb (6), media managers and program directors define Program Associated Data (PAD) and build play-lists. Schedules include advertising breaks with time constraints, pre-selected songs as well as ‘voted titles’; these are dynamically updated through the DaletPlus Impex gateway (4) by the Mazzika SMS manager (7) which tracks votes forwarded by Mazzika viewers using their mobile phone. DaletPlus OnAir (8) drives Omneon server play-out and pushes Program Associated Data to Orad DVG graphic engines (9) which automatically generate corresponding CGs and digital video effects.
