malgrado le possibili combinazioni i Servizi di
WEBTELEVISION su Rete IP si distinguono in tre famiglie
WEBTELEVISION
una parola, molti significati..
le coniugazioni della WEBTELEVISION
• PC-TV: originata da tutti i soggetti che stanno sul WEB: Content Providers, Broadcasters,
Operatori, ISPs. Adotta la tecnologia Internet e il contenuto è destinato principalmente ai PC. I
contenuti vengono selezionati attraverso WEB Browser e visualizzati tramite player software.
• IP-TV: originata dalle Telco che raccolgono o comprano contenuti dai Broadcasters e dalle Majors
per offrirli esclusivamente agli utenti connessi sulle loro reti IP attraverso un STB proprietario
connesso al proprio Televisore
• OTT-TV: originata bai Broadcasters per i device connessi alla rete Internet: STBs e iDTV set retail.
Offrono un accesso non lineare ai propri contenuti adatti principalmente allo schermo televisivo:
catch-up TV, Video on Demand, Virtual Linear Channels,… E’ la risposta pubblica dei Broadcasters
(OTT-TV) alla IPTV selettiva delle Telco (IPTV).
• Widget Gallery: è una forma di OTT-TV originata dai TV manufacturers per i Connected TV
Internet disponibili sul mercato retail. Fanno da gatekeeper di contenuti e servizi offerti da
Broadcasters e Content Providers, originati per Internet e riadattati allo schermo televisivo. E’ la
risposta dell’Industry ai Broadcasters (OTT-TV) e alla Telco (IPTV).
Is Broadcasting still alive ?
Broadcasting is under sledge..
CHANCES
TREATS
• “Broadcasting is dead” broadcast TV popularity
decrease of interest on younger viewers
• Connected TV: multimedia contents are aggregated by
manufacturers on their own Widget TV portals.
• Google TV, NETFLIX and Apple TV increase their
appeal offering value content to Internet population.
• Younger viewers prefer Internet to TV Programs
• UGC (*) and Best of breed TV Programs can be easily
downloaded online by internet aggregators than on TV.
• Telco’s IPTV has not taken off as expected:
undistinguished offering of contents with a lack of
original productions reduce interests on customers
• Internet population growths up quickly as per
business revenues and bandwidth capacity.
• Hybrid devices availability. They are close to become
a commodity
• OTT-TV: a new seamless experience between linear
broadcast and non linear broadband access: Live Tv;
Catchup TV; Timeshifted TV
BROADCASTER NEEDS A NEW DEFENSIVE STRATEGY:
•EXTEND TRADITIONAL BROADCAST TV EGEMONY TOWARDS NEW APPEALING ON
DEMAND LIKE EXPERIENCE
“FROM LINEAR TO NON-LINEAR FRUITION”

Screen Display increase the time spent by the viewers
up to 100 min. (feature film)
3. Internet video streamed contents are prepared with
quality parameters: resolution, frame rate, codecs
suitable for small/medium PC screens.
3. Broadband video streamed contents are prepared with
specific quality parameters: resolution, frame rate,
codecs suitable for large screen TV display (HD).
4. Internet video is normally streamed with SS profiles
at 500 < 1,2 Mb/s.
4. Broadband video contents is streamed with AS profiles:
SD: 0,8 < 2,4 Mb/s.; HD: 1,5 < 4,5 Mb/s.
5. HTTP servers tailored to serve bursty traffic
instead sustained hi speed HTTP videos
(HTML
small objects or graphic components)
5. Hi performance HTTP video streamers specifically
designed to provide sustained hi speed traffic (long
form streaming content)
6. Hi performance Video streaming engines only
applies to Microsoft & Adobe streaming solution
specifically designed for PC environments.
6. compatible receivers make use of industry standard
broadcast quality codecs & containers for a better
large screen TV experience

CONCLUSIONS
•
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.
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.
