1 ISO Media Based File Format and its Derivatives for DPIF Symposium at Dresden, Germany Wo Chang, NIST Digital Media Group, Manager Chaired of MPEG Query Format AHG Chaired of MPEG Multimedia Application Formats AHG Chaired of MPEG-7 Profile AHG Chaired of MPEG-4 Reference Software AHG Co-Chaired of JPEG Search Subgroup DPIF Symposium at Dresden, Germany, April 21 – 23, 2010, Wo Chang, NIST

2 ISO Base Media File Format Objectives The ISO Base Media File Format (BMFF) provides structural and media data information for timed presentations of media data such as audio, video, metadata, etc. The structure is intentionally general, so that by structuring files in different ways the same base specification can be used for files in:  Capture  Exchange and download, including incremental download and play  Local playback  Editing, composition, and lay-up  Streaming from streaming servers DPIF Symposium at Dresden, Germany, April 21 – 23, 2010, Wo Chang, NIST
