Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting
17、Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 199
18、5 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the standardization of radio and television receivers. The EBU is a professional association of broadcasting organizations whose work includes the co-ordination of its
19、members activities in the technical, legal, programme-making and programme-exchange domains. The EBU has active members in about 60 countries in the European broadcasting area; its headquarters is in Geneva.

21、ata services. DVB fosters market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and consumers. DVB standards cover all aspects of digital television from transmission through interfacing, conditional access and interactivity for digital video, audi
22、o and data. The consortium came together in 1993 to provide global standardisation, interoperability and future proof specifications. Introduction MPE-IFEC is introduced to support reception in situations of long duration erasure on the MPE section level spanning several consecutive time slice burst
23、s. Such erasure situations may for example occur on LMS channels without any terrestrial repeaters in the vicinity: obstacles may hinder direct satellite reception and induce losses of several successive bursts. For example, with an MPE-IFEC protection where about 30 % of TS data are allocated to pa
24、rity overhead computed over 10 successive bursts, it is possible to compensate up to 3 successive complete burst losses whereas recovery of a complete burst loss with DVB-H MPE-FEC protection would not be possible. Such erasure situation may also occur in terrestrial networks so that MPE-IFEC may be
