IP Datacast over DVB-H: Content Delivery Protocols (CDP)

5 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 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 telecommunications domains (e.g., mobile / cellular). Harmonisation of the IP Datacast over DVB-H content delivery protocols with 3GPP MBMS [1] has been one of the natural goals of the work. DVB BlueBook A101 6 1 Scope The present document defines a set of Content Delivery Protocols for streaming and file delivery services to be used with IP Datacast over DVB-H [2]. Delivery protocols will be IP-based and will be implemented both in content servers and IP Datacast terminals. The present document includes information applicable to broadcasters, network operators, service providers and manufacturers. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
