Is there a need for an HBB-CDI ?? Internet CDN vs. HBB CDI 1.Global Content to Global User 2.Video consumption over PC screens does not exceed 15>20 min. of continuing viewing (snack TV) 3.Internet video streamed contents are prepared with quality parameters: resolution, frame rate, codecs suitable for small/medium PC screens. 4.Internet video is normally streamed with SS profiles at 500 < 1,2 Mb/s. 5.HTTP servers tailored to serve bursty traffic instead sustained hi speed HTTP videos (HTML small objects or graphic components) 6.Hi performance Video streaming engines only applies to Microsoft & Adobe streaming solution specifically designed for PC environments. 7.Content prepositioning mainly designed for VoD services only. 8.Live channels distribution not optimised (unicast) 9.Timeshifted service (PVR) not optimised (unicast) Internet CDNs 1.Local Content to Local Viewers 2.Broadcast quality video contents streamed on Large Screen Display increase the time spent by the viewers up to 100 min. (feature film) 3.Broadband video streamed contents are prepared with specific quality parameters: resolution, frame rate, codecs suitable for large screen TV display (HD). 4.Broadband video contents is streamed with AS profiles: SD: 0,8 < 2,4 Mb/s.; HD: 1,5 < 4,5 Mb/s. 5.Hi performance HTTP video streamers specifically designed to provide sustained hi speed traffic (long form streaming content) 6. compatible receivers make use of industry standard broadcast quality codecs & containers for a better large screen TV experience 7.Edge nodes capable to either caching off air (DTT) or multicast (IP) broadcast channels. 8.Live channels video contents leverage on optimised broadcast/multicast network solution. 9.Timeshifted video content leverage on caching off air (DTT) broadcast channels.

After IPTV service managed by Telcos and on-line videos provided by the global Content Aggregators: You Tube, Google, Apple.., also Broadcasters come to the playground with their OTT-TV services aimed to regain competitiveness on TV business bringing back lost viewers to Television and TV set. Throughout OTT-TV service, the Broadcasters intends to set a new benchmark in IP offerings, leveraging on the coexistence of broadcast and broadband networks. The viewer will endorse a better user experience on a smart mix of seamless linear and non-linear content fruition, using legacy hybrid receivers: TV STB and iDTV set. Some Broadcasters will try to extend their competence in the new arena also playing the role of content distributors upon owned broadband networks in a fair coopetition with Telcos and ISPs to gain value and reduce costs. CONCLUSIONS Q: Broadbander : a new stakeholder in the network competitive arena. Treat or chance for Telcos ? A: If all stakeholders will enter in a Coopetitive scenario and leave every actors on the field to play its own role: Brodcasters, Telcos, ISPs, there will be chances enough in the media supply chain, to benefit of a win win solution on respect of the enduser needs.
