#Digital Caribbean: Skip Pizzi, NAB, USA

  1. 1. Skip Pizzi Senior Director, New Media Technologies National Association of Broadcasters Washington, DC
  2. 2. • Standards development organization for digital television – Focused on terrestrial digital television broadcasting • The ATSC DTV Standard has been adopted throughout North America, in South Korea, and in several Central American and Caribbean nations. • Migration path for upgrades in progress About the ATSC
  3. 3. The Evolution of ATSC
  4. 4. ATSC DTV Standard (A/53) – “ATSC 1.0” • Optimized for single-transmitter service (power-efficient) • Spectrally efficient (especially important for regions with 6 MHz channelization) • HDTV-capable from the start • Numerous incremental improvements to date, with more to follow
  5. 5. ATSC 1.0 DTV • High definition video • Standard definition video • Multichannel sound Mobile DTV • Robust • AVC video • IP transport • HE AAC audio • Backward- compatible 3D-TV • Multimode • Supplemental - Main channel - Mobile - Broadband • Independent ATSC 2.0 • AVC/MPEG-4 video coding • Non-real-time (NRT) • Conditional access • Digital rights management • Advanced EPG • Audience measurement ATSC Evolution ATSC 3.0
  6. 6. ATSC Flexibility 6 Increased Transmitted ResolutionIncreased Number of Services 720P 1080P/I480I 480P
  7. 7. Example #1 Example #2 Example #3 Example #4 Mobile Services 1 4 2 2 & 10 Audio Services Relative Quality High Quality Mid Quality Mid Quality Mid Quality Video Bit Rate (kbps) 768 1600 800 800 Audio Bit Rate (kbps) 24 96 48 4 Mobile Total (Mbps) 3.688 7.336 3.668 5.502 Main/legacy (Mbps) 15.722 12.054 15.722 13.888 Flexible Mobile Service Combinations
  8. 8. • M-EAS is an enhancement of mobile DTV Standard to deliver emergency information to mobile/handheld receivers – Real-time – Non-real-time • Common Alerting Protocol • NRT used to provide rich media assets Evolution: Mobile Emergency Alert System
  9. 9. ATSC 3.0• ATSC 3.0 Next Generation Broadcast Television – Fundamental Technology Shift • Flexible & Efficient • 3.0 must provide performance improvement and additional functionality significant enough to warrant implementation of a non-backwards compatible system – Timeframe Factors • Business requirements • Regulatory (Spectrum) issues • Technology advancement – Target Completion: 2016-2017 Revolution
  10. 10. Application & Presentation (apps, player, UI, codecs, etc.) Management, Service, Discovery Protocols (Bitstream) Physical Layered Model
  11. 11. • Improved Coverage & Service –Highly robust –Support various network architectures • High Power Central Transmitter • Single Frequency Networks • Hybrid System Requirements
  12. 12. • Efficiency –Number of bits available for a given bandwidth (bits/hertz) –Improved compression technologies Example Target: Minimum of 6x improvement compared to first- generation systems System Requirements
  13. 13. • Mobile & Handheld • Ultra High Definition –3840 x 2160 (“4K”) –7680 x 4320 (“8K”) System Requirements
  14. 14. • Flexibility/Scalability – Bandwidth Utilization • Cannot assume fixed-bandwidth channels in future (such as 6, 7 or 8 MHz) Example Target: System dynamically configurable for 0.25 MHz to 25 MHz channels System Requirements
  15. 15. • Audio – 22.2 Channel? – Object-oriented? – Metadata to support different listening environments • Accessibility – Inherent support to meet needs of sensory- impaired 16 System Requirements
  16. 16. • All first-generation systems (ATSC, DVB-T and ISDB) have similar performance – There are differences, but they are not significant enough to be the basis for system selection • All systems are evolving • Implementation cost for a given service (HDTV, Mobile, etc.) are about the same for ATSC, DVB and ISDB – Although ATSC xmtr power requirements are lower • Intellectual Property costs must be considered Final Comments
  17. 17. Key Decision Points • Caribbean region is diverse – Terrains, topologies and cultures vary widely • ATSC favors independent, single- transmitter environments • Focus on total cost to the consumer – Proximity to and critical mass of larger neighboring markets is dominant factor • Availability & time-to-market – Most flat-screen TVs in NTSC countries already support ATSC 1.0
