Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBU/ETSI JT
22、C Broadcast was established in 1990 to co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the standardization of r
23、adio and television receivers. The EBU is a professional association of broadcasting organizations whose work includes the co-ordination of its members activities in the technical, legal, programme-making and programme-exchange domains. The EBU has active members in about 60 countries in the Europea
24、n broadcasting area; its headquarters is in Geneva.

25、re developers, regulatory bodies, content owners and others committed to designing global standards for the delivery of digital television and data services. DVB fosters market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and consumers. DVB stand
26、ards 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 provide global standardisation, interoperability and future proof specifications. The present document i
27、s part 1 of a multi-part deliverable covering IP Datacast: Implementation Guidelines for Mobility, as identified below: Part 1: “IP Datacast over DVB-H“; Part 2: “IP Datacast over DVB-SH“. Introduction IP Datacast over DVB-H is an end-to-end broadcast system for delivery of any types of digital cont
28、ent and services using IP-based mechanisms. An inherent part of the IPDC system is that it consists of a unidirectional DVB broadcast path and a bi-directional mobile/cellular interactivity path. IPDC is thus a platform for convergence of services from mobile/cellular and broadcast/media domains. ET
29、SI ETSI TS 102 611-1 V1.3.1 (2010-03)61 Scope The present document presents guidelines on how to develop terminals and network infrastructure equipment to allow seamless handover within the scope of one IP Platform, one ESG, and one IPDC Operator, in order to continue IP Datacast service consumption
30、. Additionally, the present document specifies enablers for mobility between IP Platforms, ESGs, and IPDC Operators. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

39、rposes of the present document, the following terms and definitions apply: cell: geographical area that is covered with DVB-H signals delivering one or more particular transport streams throughout the area by means of one or more transmitters NOTE: The cell may in addition contain repeaters. Two nei
40、ghbouring cells may be intersecting, or fully overlapping. The cell_id that is used to uniquely identify a cell is unique within each original_network_id. For hand-over purposes it is more convenient if the transport streams associated with the cell cover exactly the same area, or only one transport
41、 stream per cell is used. DVB Network: collection of MPEG-2 Transport Streams, each carried in a multiplex, and transmitted on a single delivery system NOTE: DVB Network is identified by network_id. home ESG: ESG(s) the terminal has been provisioned with by his Home IPDC Operator as its home configu
42、ration home IP Platform: IP Platform(s) the terminal has been provisioned with by his Home IPDC Operator as its home configuration home IPDC Operator: IPDC Operator that the terminal is registered to IP Flow: flow of IP datagrams each sharing the same IP source and destination address NOTE: An IP Fl
43、ow is identified within an IP Platform by its source and destination addresses. IP Flows on different IP Platforms may have the same source/destination addresses, but are considered different IP Flows. IP Flows may be delivered over one or more IP Streams. IP Platform: set of IP Flows managed by an
44、organization NOTE: The IP Platform represents a harmonized IP address space that has no address collisions. An IP Platform may span several Transport Streams within one or more DVB Networks. Several IP Platforms may co-exist in the same Transport Stream. IP Platform is identified by platform_id. IP
45、Stream: physical mapping of an IP Flow to transport_stream_id, original_network_id, service_id, component_tag, and IP source/destination addresses NOTE: An IP Stream is delivered on an MPE section stream. IPDC Handover: change of the terminal connection (one or more of the parameters original_networ
46、k_id, transport_stream_id, network_id, cell_id / subcell_id) within the scope of one IPDC Operator (while accessing IPDC services) IPDC Operator: characterized uniquely by IPDCOperatorId and IPDCKMSId NOTE: A physical IPDC Operator may have several IPDCOperatorIds which each map to an IPDC Operator
47、in the defined sense. IPDC Roaming: change of a terminal connection from an IPDC Operator to a Roaming IPDC Operator local IPDC Operator: IPDC Operator that himself offers services on a certain IP Platform and ESG ETSI ETSI TS 102 611-1 V1.3.1 (2010-03)8multiplex: stream of all the digital data carr
48、ying one or more services within a single physical channel (characterized by parameters like carrier frequency and modulation modes) Service Mapping: procedure based on the ServiceMapping element in the ESG Service fragment, allowing the terminal to find the same or similar IPDC service when it chan
49、ges the reception, and to continue consuming it Sub-Cell: geographical area that is part of the cells coverage area and that is covered with DVB-H signals by means of a transposer NOTE: In conjunction with the cell_id the cell_id_extension is used to uniquely identify a subcell. Transport Stream (TS): stream of transport_packets, as defined in ISO/IEC 13818-1 1 roaming configuration: combination of platform_id, ESG_URI (provider_URI and providerID in case of IPDC phase I), and the pair of IPDCOperatorId and IPDCKMSId roaming IPDC Operator: IPD
