scope:

The present document specifies a protection scheme for the MPE sections specifically adapted for broadcasting environments supporting long duration fadings such as DVB-SH.

• Clause 3 introduces the (normative) definitions, symbols and abbreviations.

• Clause 4 introduces the (normative) sender operation. The present document specifies a generic framework that exhibits enough flexibility for a variety of applications, some of which are mandated for a usage in DVB-SH in the "framework mapping" in clause 6.

• Clause 5 describes the (normative) carriage of MPE-IFEC sections.

• Clause 6 provides (normative) syntax of Time Slice and FEC identifier descriptor. Two mapping of the generic framework are given:

- One based on MPE-FEC Reed Solomon code (EN 301 192 [1], clause 9.5.1) and called "sliding RS encoding" is normative.

- Another based on Raptor code (TS 102 472 [2]) and called "generalized encoding with Raptor code" is informative.

• Annex A introduces (informative) prototype IFEC decoding.

NOTE: The present document is intended to be ultimately added as an annex to EN 301 192 [1] but can be used independently as it is natively self-contained.
