Translation of "media resource" into German

Any media item that can be transferred over any network as a binary stream. One media item could have multiple binary streams depending on the encoding features. For example, some media items could have three streams (or resources): WMV encoded stream for a 2 Mbps throughput, WMV encoded stream for a 500 Kbps throughput, and MPEG-2 encoded stream for a 5 Mbps throughput.
