  8. 8. Page8 Introduction | DVB-H • DVB-H was never a success – No business case • Very few DVB-H receivers in the market • No demand for watching TV on a tiny cell phone screen (QVGA, 320 x 240) - and certainly not if you had to pay for it
  9. 9. Page9 Introduction | Bigger mobile screens • Mobile phone evolution
  10. 10. Page10 Introduction | Bigger mobile screens - new opportunities • With the increasing popularity of iPads since 2010 and other tablets & smartphone, the demand for linear TV viewing on “smaller” screens has arrived. • The challenge with tablets and smartphones are that they have a screen size of 1080p or 2K. • The bandwidth necessary for unicast mobile TV can be a challenge for mobile operators - especially during major sporting events. • Here, DVB-T2 or T2 Lite in combination with HEVC provides an efficient new platform for broadcasting SD and HD to mobile device. • Most mobile hardware from late 2014 onwards supports dedicated HEVC playback.
  11. 11. Page11 Introduction | A shift from Fixed to mobile Devices • Share of total TV time by age group, measured on respective device in 2015
  12. 12. Page12 Introduction Mobile phones have replaced radio sets| • Back in the 1930s, radio was a spectacle. Listeners sat and watched the radio set which held centre stage in the living room. Television taught us that radio was not the best spectacle anymore and some predicted the death of radio. • Radio's rebirth came with exclusive free music and free instant information, live. The explosion of portable radio through transistor and car radios underlined its unique position. • But 24‐hour cable news channels removed radio’s distinction of immediacy; to be challenged today by alerts on mobile phones. And the arrival of the internet, and its infinite bounty of music to listen to, removed radio’s exclusivity on free music. • At the same time, mobile phones have replaced radio sets. Where can you buy radios now? • You won’t find a transistor radio under a teenager’s pillow anymore; you’ll find a mobile phone.

  13. 13. Page13 Introduction | Sound quality HE-AACv2 • DVB-T2 as well as DAB+ & DRM+ uses HE AACv2 audio codec With original encoded program material: • Acceptable quality stereo sound at 24 – 32 kbps. • Good "FM-like" sound at 64 kbps or higher. (64 kbps sets the lower limit of audio quality on the speech by HE-AAC). • Transparent high quality stereo sound at 128 kbps. • The maximum bit rate of the encoded audio shall not exceed 192 kbps for a stereo pair.
  14. 14. Page14 Introduction | Stat mux Gain • Statistical multiplexing efficiency depending on the number of programmes.
  15. 15. Page15 DVB-T2 | Improved robustness • The commercial focus on DVB-T2 was originally mainly on stationary reception, but DVB-T2 is also designed to work well in mobile/handheld conditions. • DVB-T lacks time interleaving and so it is sensitive to impulsive interference (e.g. from sparks) and the changes in the radio propagation experienced in mobile reception (e.g. caused by path obstructions, 'shadows' ). • DVB-T2 has support for deep time interleaving, which radically improves the robustness against impulsive noise and interference.
  16. 16. Page16 DVB-T2 | Advantages with multiple PLPs • Possibility to reach different kinds of receivers and reception conditions with a single RF signal e.g. › PLP0: UHD TV to roof-top directional antennas › PLP1: TV for mobile device with robust signal › PLP2: Digital radio with extra robust signal • Possibility to prioritize robustness for selected ”high-priority” services -> prioritized services (e.g. public service) will ”last longer” in poor reception conditions. • Statistical multiplexing over several PLPs is possible [Dynamic scheduling PLP]
  17. 17. Page17 DVB-T2 | New bandwidth 1.7 MHz (VHF band III) • DVB-T2 standard has added support for 1.7 MHz bandwidth. This is the same bandwidth that Digital Audio Broadcast (T-DAB) & Digital Multimedia Broadcasting (T-DMB) standard uses in VHF band III and L-band. • 1.7 MHz is Optional (item to include) in Nordig DVB-T2 IRD. • 1.7 MHz is (Highly) Recommended for eg. the Irish Digital Terrestrial Television DVB-T2 IRD (Saorview).
  18. 18. Page18 DVB-T2 | New profile in DVB-T2 v1.3.1 • T2-Lite is a new ”light” version of DVB-T2 to enhance mobile performance. • T2-Lite is mainly a subset of DVB-T2, except two new code rates for robustness 1/3 and 2/5. • Several other features, including low bitrates (peaking at 4Mbps per PLP) and short forward error correction frames (16k), co-exist with these coding rates to collectively offer a sharp reduction in receiver power use. • The benefit is less demand on CPU performance and power, making it highly suitable for tablets and smartphones already on the market today.
  19. 19. Page19 DVB-T2 | T2-Base-Lite profile • T2-Base-Lite is a perfect DVB-T2 profile for digital radio & mobile-TV • L1 pre-signaling "T2_BASE_LITE" A mode in which this bit is set to ‘1’ will therefore be suitable for reception by both T2-base-only and T2-lite-only receivers. • The significance of T2-Base-Lite for broadcasters and DTT operators is that it removes the barriers to commercial mobile DTT broadcasting success with without the cost of building a dedicated network for mobile only TV.
  20. 20. Page20 Network planning | Importance of frequency
  21. 21. Page21 Network planning | Choice of FFT - for portable receivers • FFT for mobile reception: 1K, 2K, 4K or 8K • FFT for portable reception: 8K, 16K • FFT for rooftop reception: 32K Required C/N for DVB-T and DVB-T2 as a function of the velocity of the mobile receiver with FFT 8K (16QAM & time interleaving depth 100 ms)
  22. 22. Page22 Network planning | FFT 32K -> Future Extension frames • A mechanism that allows a future system to be sent as “Future Extension frames” (FEF) in T2 time slots. • FEF makes it possible to have two different FFT size in a single RF mux, where T2 Base has 32K and T2 Lite in FEF have a different FFT size e.g. 8K • T2-Lite is the first additional transmission profile type that makes use of the FEF approach.
  23. 23. Page23 T2 Lite in FEF | HD roof-top + Mobile SD reception
  24. 24. Page24 T2 Lite in FEF | HD/SD roof-top + Digital Radio
  25. 25. Page25 Network planning | Polarization - for mobile device • If the special aim is portable receivers served in major cities, then vertical polarization (or circular polarization) should be chosen; area coverage losses are to be accepted. • Vertically polarized waves undergo a greater attenuation on long transmission paths than horizontally polarized waves. • Vertical polarization favor’s so-called multipath propagation through numerous reflective vertical elements in nature, such as lampposts.... • Vertically polarized waves generate higher field strengths near the ground. • Antennas for portable receivers are often oriented vertically out of habit, and therefore favour the reception of vertically polarized waves. • Circularly polarized radiation on mobile receivers generates less amplitude variation, i.e. it increases the likelihood of usable field strength, and at the same time serves all forms of linearly polarized receiving antennas.
  26. 26. Page26 Network planning | SFN MISO • If two signals correlate (DVB-T2 SISO SFN) it leads to severe degradations of the signal which need to be compensated by higher field strength. • Areas with similar signal levels show a statistical “SFN Gain”. But this gain is insufficient to compensate for this increase in the required minimum field strength. When removing this correlation using MISO the “SFN Gain” contributes fully to the coverage. • Another effect also improves the coverage range of the transmitters. In areas with similar levels and a short delay between the echoes, MISO lowers the required minimum field strength relative to the non- MISO case. • The total effects are shown in the following simplistic coverage planning example, based on a calculation with a statistical propagation model.
  27. 27. Page27 Network planning | Reception Mode
  28. 28. Page28 Network planning | MRC diversity for In-car Entertainment • MRC Diversity receivers use the Maximum Ratio Combining algorithm. • This technology enables a smart combination of the digital radio & TV signals received via several antennas. • Diversity-2 increases sensitivity that could triple the coverage area and offers better indoor reception (up to +70%). It also improves Doppler Effect handling (reception at higher speed). • It is especially useful where robust reception can be very difficult to achieve.

  81. 81. Page81 Case Sweden | Parliament Confirms Rejection of DAB Radio • The Constitutional Standing Committee (KU) in The Swedish Parliament has processed the government missive regarding the 2015 National Audit review of digital radio in which the proposal for a transition from FM to DAB+ in 2017-2022 was rejected. After a short debate and without objection from any of the eight political parties the Parliament February 3rd 2016 appended the missive to the protocol. This marks the end of 24 years of efforts to replace FM with DAB in Sweden. • Already in June 2015 the Government took the decision to reject the proposal for a digital transition for terrestrial radio. • Swedish Radio started testing DAB in Stockholm continuous since 1992 and officially went on air 1995 the same year as BBC introduced DAB in the UK. • In 2005 DAB was rejected for the first time by the socialdemocratic government. Program have been broadcast in an inofficial mode via DAB and DAB+ transmitter in four major cities but few listeners are reported.
  82. 82. Page82 Device | Review First DAB+ smartphone • LG Stylus DAB+. A large mid-range phone, but radio disappoints • The inclusion of digital radio is a generally positive feature, but it’s not without some significant limitations. • Your headphones act as the effective antenna for the radio, which means you can’t just use the smartphone as a wider broadcast radio to a room without plugging in some form of wired speaker. • What’s more apparent from a week’s testing is that even in Sydney, digital radio reception on the move can vary widely.

  100. 100. Page100 HEVC | Case France • From April 5th 2016 all new multiplex and TV channels in Ultra HD will be with DVB-T2 and HEVC video codec in France in accordance with France law “Avis n° 2015-16” September 30th 2015.
  101. 101. Page101 HEVC | Case Italy • DVB-T2 is mandatory from July 1st 2016 and • HEVC from January 1st 2017 in accordance with Italian law (March 2015).
  102. 102. Page102 HEVC | Case Australia, Netherlands & Croatia Australia • In a response to the Consultation Paper: “Digital Television Regulation” circulated by the Department of Communications early 2015, both commercial and national broadcasters expressed an interest in moving to the DVB-T2 transmission standard in combination with the HEVC encoding compression standard. Netherlands • Dutch public broadcaster NPO is looking to broadcast its free-to-air channels NPO1, 2 and 3 in HD using the DVB-T2 & HEVC standard in the future (maybe from 2017 onwards). Croatian • The Croatian Regulatory Authority for Network Industries (Hakom) is working March 2016 on a new draft strategy for the transition to the DVB-T2 HEVC DTT standard.
  103. 103. Page103 HEVC | Case Germany • First DVB-T2 DTT platform with HEVC. • First DVB-T2 broadcast with true FULL HD (1080p50).
  104. 104. Page104 HEVC | Case Germany • The DVB-T2 platform will launch in urban areas in May 31 2016 with the transition to be completed in mid-2019. Trials are currently taking place in Berlin, Munich and Cologne/Bonn. • With DVB-T2, HD channels will become available terrestrially in Germany for the first time, many of them in Full HD mode (1080p50) and therefore in better resolution than on cable and satellite. • The lineup will contain 40 to 45 channels. The public broadcasters’ channels will be FTA while the two large commercial TV groups RTL and ProSiebenSat.1 will be encrypt. • Further channels and offerings will get to viewers’ TV screens via HbbTV.
  105. 105. Page105 HEVC | Case Germany • More channels with DVB-T2/HEVC • DVB-T (16QAM | CR 2/3) vs DVB-T2 (64QAM | CR 2/3).
  106. 106. Page106 HEVC | Case Germany • Extended Coverage
  107. 107. Page107 HEVC | Case Germany • DVB-T2 vision 1.3.1 including L1 Post Scrambling • Required T2-Parameters: similar robustness as today while maximizing bandwidth and including basic mobile functionality. • Optimised T2 parameters with -1,5dB as device testing confirmed that new receivers have improved by +2dB. • T2 parameters derive 27,6 Mbps per mux and can host up to 7 HD HEVC TV channels. • Public broadcasters go for a mobile optimized configuration while reducing the number of TV channels (max. 5 - 6 HD).
