DVB fosters market driven solutions tha

DVB standards cover all aspects of digital television from transmission through interfacing, conditional access and interactivity for digital video, audio and data. The consortium came together in 1993 to p
29、rovide global standardisation, interoperability and future proof specifications Introduction IP Datacast over DVB-H is an end-to-end broadcast system for delivery of any types of digital content and services using IP-based mechanisms optimized for devices with limitations on computational resources
30、and battery. An inherent part of the IPDC system is that it comprises of a unidirectional DVB broadcast path that may be combined with a bi-directional mobile/cellular interactivity path. IPDC is thus a platform that can be used for enabling the convergence of services from broadcast/media and telec
31、ommunications domains (e.g. mobile/cellular). ETSI ETSI TS 102 832 V1.2.1 (2010-01)61 Scope The present document defines mechanisms for the delivery of messages which are used by the IPDC over DVB-H network to provide information about forthcoming events; such messages are referred to as Notificatio
32、n messages. The present document specifies the message format, transport and access mechanisms of Notification messages. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
