Abstract
A media server system and method are disclosed for playback of digital media. For playback, header information associated with a complex asset is received. The header information comprises information for initializing a decoder (56) for playback of the complex asset. Artificial headers (54) for the complex asset are then created using the header information. A digital packet stream for the complex asset is received and passed decoder (56) for playback. During playback, artificial headers (54) are injected as appropriate for initializing the decoder (56) for playback of the complex asset. In one implementation, the complex asset can be a clip asset (100), a parallel asset (102), a sequential asset (106) or a composite asset (110).
