DECE CFF Container Structure Clause Samples

DECE CFF Container Structure. ‌ The Common File Format SHALL be compatible with the ‘iso6’ brand, as defined in [ISO]. However, additional boxes, requirements and constraints are defined in this specification. Included are constraints on layout of certain information within the container in order to improve interoperability, random access playback and progressive download. For the purpose of this specification, the DECE CFF Container (DCC) structure defined by the Common File Format is divided into three sections: DCC Header, DCC Movie Fragments, and DCC Footer, as shown in Figure 2 -2. • A DECE CFF Container SHALL start with a DCC Header, as defined in Section 2.1.2. • One or more DCC Movie Fragments, as defined in Section 2.1.3, SHALL follow the DCC Header. Other boxes MAY exist between the DCC Header and the first DCC Movie Fragment. Other boxes MAY exist between DCC Movie Fragments, as well. • A DECE CFF Container SHALL end with a DCC Footer, as defined in Section 2.1.4. Other boxes MAY exist between the last DCC Movie Fragment and the DCC Footer.
