Abstract
A method and system is provided to avoid the duplicate storage and transfer of multimedia data in a playback device, thereby increasing system bandwidth and available playback memory. A multimedia composition describes an edited piece of audio and video multimedia data. The composition is created and transferred to a playback device. The composition is examined to determine whether the multimedia data referred to in the composition is already stored in the playback device. If the data is stored in the playback device, or in transit to the playback device, it is not transferred to the playback device.
