New broadcasting standards for compression (HEVC, H.265) satellite transmission (DVB-S2 Extensions) and quality (UHDTV 4K/8K) are entering the market, leading to a better user experience and potential business benefits for the broadcast industry. But what is hype and what is real? Do you know how to apply them and in which applications they will be useful?

This presentation elaborates on:

- DVB-S2 Extensions improving satellite efficiency
- How to save bandwidth with MPEG HEVC
- How to put UHDTV into practical use or whether it is
just another fad to sell TV
- Whether you really need to consider them all and
when you should start?

  • Calculated valuesAssumes reveiver performance @5% RO is optimalIf one increases the total symbolrate used in the transponder, the amount of power used will be increased.In case the IBO/OBO needs to be maintained, the power will need to be the same, so the power per carrier will decrease.It will be decreased by 10*log(1.2/1.05) = 0.58 dB So the Es/No of the received carriers will be reduced by 0.58 dB which will decrease the availability.In case the same total power needs to be maintained and the availability cannot be reduced, the modcod will need to be lowered.So in this case 16APSK 4/5 will need to be used (16APSK 5/6 requires 12.1 dB, 16APSK 4/5 requires 11.5 dB nicely the 0.6 dB that we need to give in).Remark : Equalink does not give benefits in a multi-carrier transponder, since the transponder is not saturated!

  • You can upgrade existing DTH and other satellite distribution platforms to S2 Extensions now, to get tangible benefits and ROI, with installed base of STBs.S2 Extensions & HEVC will have a big impact during 2013/2014 in primary distribution of DTT DVB-T2 and to cable head-ends. Most new ‘green field’ DVB-T2 deployments will be looking to use HEVC end-to-end in 2014/2015 timeframe.HEVC will make impact in 2013/2014 in distribution of mobile, SD & HDTV, where the installed based of receivers (e.g. updates for software or FPGA based decoders) does not limit rollout.There is little doubt a whole new set of opportunities could be opened up for 4K. For example, BSkyB proved that millions of subscribers are willing to pay an extra 10 pounds per month for HD channels and, once consumers see more and more 4K, especially during in-store demos, The payTV business also has a vested interest in maintaining a video differential compared with the likes of Netflix, Lovefilm and YouTube. 4K, transmitted by satellite, is the answer to that OTT battle?
  • There is little doubt a whole new set of opportunities could be opened up for 4K. For example, BSkyB proved that millions of subscribers are willing to pay an extra 10 pounds per month for HD channels and, once consumers see more and more 4K, especially during in-store demos, it could command the price premium that 3D has struggled to do so. The payTV business also has a vested interest in maintaining a video differential compared with the likes of Netflix, Lovefilm and YouTube. 4K, transmitted by satellite, is the answer to that OTT battle.
  • We mentioned that there is are drivers to ‘All IP Infrastructure’ for the introduction of 4K, for mezzanine, file workflows, etc.This opens many possibilities with distributed workflows and head-ends.If you are considering this or already use IP in the playout & head-end (or IP link between head-ends & uplinks) there is the need for FEC (Forward Error Correction).After the stat-mux in the DTH playout, you can just cannot afford to lose any packets.Our modulators support the SMPTE 2022-1 (ProMPEG COP3) standard to reliably deploy distributed IP headends via the GbE interfaceIt’s there if you need it!Forward Error Correction is a key technology to correct errors in the incoming transport stream on the GbE ports, prior to transmission on satellite.  Such errors can have several causes, s.a. malfunctions in video encoders and multiplexers, and packet drops in the IP distribution network due to e.g. long cabling or network overloads. In unicast transmission, such packet errors are corrected by the TCP layers of the OSI protocol stack. However, in most video systems, multicast is used on UDP or RTP, and those layers do not have the retransmission capabilities built in. Hence the need to insert forward error correction in the transmission link between the video headend and the satellite modulators.  Column FEC provides correction for consecutive burst packet loss of up to L packets. The FEC packets are generated per column within the matrix allowing loss of any single media packet within a column or burst of error within a row to be corrected through the FEC packet. Column FEC is ideal for correcting packet burst errors and random errors.  Row FEC provides correction of non-consecutive packet loss and can correct any single packet loss within a row of media packets. The FEC packets are generated per row allowing loss of any single packet to be recovered. Row FEC is ideal for correcting random packet errors. Key benefits The M6100 corrects errors in the incoming stream pro-actively using SMPTE2022-1 (ProMPEG COP3).This capability allows safe remote deployment of modulators connected (remotely) over IP to the video headend. The M6100 has all hardware on-board to support L (row) and D (column) up to 20, where L*D <=100. The FEC can be enabled by means of a software license key at any time.The M6100 corrects the error, but also removes the FEC overhead prior to transmission. The error count and number of corrected errors are reported, the operator can use this information to monitor the link quality between video headend and modulator.
