Encoding samples and recommendations

Encoding is done for each format needed and a signal is prepared for every network/operator. The most efficient way is to prepare one high bit-rate “Master Signal” for all the needs of TV service providers (networks). The “Master Signal” enables further transcoding to the required format, if necessary. This can be done by us or by the target TV service provider (for example, a cable or IPTV operator). Signals in this format are, as a rule, also accepted by bigger terrestrial and/or satellite operators for re-encoding because they do not cause a significant loss in video quality.As an example following encoding formats can be prepared:
“Master Signal” in SD:

  • Encoding format: AVC MP@L 3.0 or higher
  • Video resolution: 576i@50
  • Recommended bit-rate: 8 Mbps (CBR or max VBR)
  • Audio 1: Original MPEG-2 layer2 @ 256 kbps
  • Audio 2: B-language MPEG-2 layer2 @ 256 kbps
  • DVB sub: multilang. resync. approx. burst max@160kbps
  • TTX sub and WSS support
  • N+M automatic redundancy scheme under system control
 “Master Signal” in HD:

  • Encoding format: AVC HiP@L 4.0 or higher
  • Video resolution: 1080i@50
  • Recommended bit-rate: 20 Mbps (CBR or max VBR)
  • Audio 1: Original MPEG-2 layer2 @ 256 kbps
  • Audio 2: B-language MPEG-2 layer2 @ 256 kbps
  • Dolby AC3 pass-through: Original @ 384 kbps
  • DVB sub: multilang. resync. approx. burst max@160kbps
  • N+M automatic redundancy scheme under system control

The “Master Signal” is to be used for further re-encoding (f.x. for DTT networks). At hand-over, it can also be decoded back to HD or SD-SDI with DVB subtitles burn-in or without. High-quality downscaling option is available.

For direct remultiplexing for relatively small cable or IPTV networks, the following encoding formats can be prepared:

“End-user ready Signal” in SD:

  • Encoding format: MPEG-2 MP@ML 4:2:0
  • Video resolution: 576i@50
  • Recommended bit-rate: 3,6 Mbps (CBR or max VBR)
  • Audio 1: Original MPEG-2 layer2 @ 192 kbps
  • Audio 2: B-language MPEG-2 layer2 @ 192 kbps
  • DVB sub, TTX sub and WSS support
  • N+M automatic redundancy scheme under system control
 “End-user ready Signal” in HD:

  • Encoding format: AVC HiP@L 4.0 or higher
  • Video resolution: 1080i@50
  • Recommended bit-rate: 8 Mbps (CBR or max VBR)
  • Audio 1: Original MPEG-2 layer2 @ 192 kbps
  • Audio 2: B language MPEG-2 layer2 @ 192 kbps
  • Dolby AC3 pass-through: Original @ 384 kbps
  • DVB sub: multilang. resync. approx. burst max@160kbps
  • N+M automatic redundancy scheme under system control

The “End-user ready Signal” is to be used without further re-encoding (f.x. for cable or satellite networks). Specific encoding formats and parameters depend on the needs of operators, so these are agreed upon separately.

Distribution over fiber-based dedicated Media Delivery Network

A cost-effective alternative to satellite distribution: Reliable and cost-effective delivery of HD/SD channels (SDI or ASI) from Levira’s Play-out Center to all major head-ends in Scandinavia and the Baltic states. CEE markets are under development.Allowing full localization also for smaller markets:

  • Local country specific opt-out feed with additional revenues from local ad-sales
  • Easier to reach carriage agreements
  • Better positioning in channel packages and in channel list (EPG)
  • Higher ratings

 

Encoded signals are delivered to destination networks determined by the customer. Delivery is done over Levira’s Media Distribution network based on fiber connections. Levira’s media network currently includes connections from Levira facilities in Tallinn to Riga (Latvia), Vilnius (Lithuania), Helsinki (Finland), Stockholm (Sweden), Oslo (Norway), Frankfurt and Munich (Germany), Madrid (Spain). PoPs in London, Paris, Bratislava, Warsaw, Budapest are being prepared. Other locations can easily be added, if necessary. Levira PoPs are set up at locations that have good connectivity to local networks. The services mentioned above are automatically protected with the annual SLA of 99.98%.

In Estonia, Latvia, Lithuania, Sweden, Norway and Finland, Levira can arrange fiber delivery to all major pay-TV networks. The same is under development in CEE countries.
