    Definition of terms Title:

    Abstract

    This contribution reviews definitions provided for a single term in different FG IPTV working

    documents and if they differ it proposes one which is hoped to be adopted for all documents.

    Background and discussion

    Great effort was made at the last meeting to align definition of common terms in all documents.

    However, there are still some terms hat have different definitions in different documents. This

    contribution is proposing a unique definition for such terms to be used in all documents.

    Reference

    FG IPTV-DOC-0132 (23-31 July 2007), “Working Document: IPTV vocabulary of terms Proposal
