HYBRID NETWORK POSSIBILITIES Day Two opened with an examination of the concept of hybrid networks, where a combination of broadcast and mobile broadband techniques might deliver efficiencies and the 'best of both worlds.’ By focusing on common user cases – VOD, tablet/smartphones viewing, portable reception -- Sudewestrundfunk’s Dr. Roland Beutler tried to correlate broadcasters’ expectations (unlimited audience, linear and nonlinear viewing, QoS, some free-to-air channels, mobile reception) with the possibilities currently offered by available technologies. Dr. Beutler pointed out that

there is no “single” platform capable of satisfying each key requirement demanded by both end users and broadcasters. Moreover, the total amount of data delivered via broadcast networks in 2012 was about six times greater than the total amount of data delivered via fixed+mobile broadband in 2012.
