Abstract

An extension to the ISO Base Media File Format to support ALC as a broadcast protocol. The present invention also provides for the extension of the ESG to include metadata specific to the transport of SVG over mobile broadcast/multicast networks. A “BMFDP hint track” is introduced in the container file format, with the required file metadata being in these hint tracks. The present invention can be used in applications such as the preview of long cartoon animations, interactive Mobile TV services, live enterprise data feeds, live chat services, and karaoke programs.
