Method for making a multimedia application executable on hardware platforms with various different resource levels, a physical record containing such application, and an apparatus for executing such application

摘要

Multimedia application information is stored for later executability on different platforms, such as Interactive Multimedia Distribution Format (IMDF) complying platforms. The application comprises a plurality of parallel information streams. Execution scalability is enabled by assigning to the streams a single string of quality level items that along the string indicate stepwise increasing quality levels. Each item specifies an associated decoding quality level for a particular stream.
