ATSC Mobile DTV

KEY FACTS
  • A/ 153 specifies the way the Mobile DTV content is encoded
  • Specifies the packing of the content along with signaling
  • Allows delivery of the Mobile DTV signals along side the existing SD/HD programming using the existing DTV transmission infrastructure
 KEY ADVANTAGES OF ATSC Mobile DTV
  • Higher levels of FEC reduce the threshold C/N requirement of Mobile DTV signal
  • Advanced video coding (H.264 / AVC) improves efficiency
  • Lower resolution (416 x 240 pixels) accommodates small hand held displays
  • Time slicing technology reduces battery drain on the user terminal
  • IP delivery system (RTP/RTCP over UDP over IP) taking advantage of streaming technologies
KEY BENEFITS
  • ATSC Mobile DTV provides increased audience size / viewership; stations can maintain or increase advertising revenues
  •        Spectral characteristics of 8-VSB are unchanged, no affect on existing licensing
  •        An in-band solution that maintains compatibility with existing SD/HD legacy distribution
  •        Existing Thomson Broadcast ADAPT-IV DTV exciters are software upgradable

Key Features

  • A/153 allows broadcasters to launch ATSC Mobile DTV quickly and with minimal capital expenditures using their existing high power DTV transmitter.
  • Broadcast stations already have the local content that consumers want on the go – content remains king
  • ATSC Mobile DTV can be deployed free-to-air for quicker consumer adoption
  • RF signal coverage enhancements are available with:
    • Increased transmitter power, maximizing ERP
    • Adding circular polarization
    • Implementing Single Frequency Networks (SFN) for terrain shielded coverage
  • A/153 is modular and allows for future upgrades and enhancements including:
    • Scalable Video Codec (SVC) providing high(er) resolution for back-seat entertainment systems
    • Non-Real Time (NRT) for new value added services such as clip-casting and push services (VOD, music, games, interactive content, etc.)
    • Service protection
