81. ine 12 8 2 EBU email Peter MacAvock 1 How can aggregators distributors benefit from HbbTV This is an interesting but very relevant question Aggregators form an important part of the broadcasting chain they are sometimes referred to as Multiplex Operators Whilst HbbTV is typically a set of services online which are triggered from a broadcast signal there is perceived benefit from the gathering together of some of the services to offer these across platforms Taking the case of a terrestrial television multiplex operator he has to gather 97 information from all of his content providers for the purposes of tuning and some basic EPG information To extend this to the HbbTV signalling information is logical and if there is an agreement between the different participants on a particular platform or multiplex there is the possibility to arrange joint advertising deals if allow or even harmonise the offering of applications across content providers Naturally this depends on what the rules in a given market permit Concerning cable operators other large content aggregators there is a slightly different set of requirements since in many cases these people will also be offering their own services similar to broadcaster centric services Thus ensuring that HbbTV services don t eat into their own offerings is important Nonetheless it is our experience that the cable sector is divided into two camps one wher
