Publication number: 20230388565Abstract: Audio video synchronization and alignment or alignment of audio to some other external clock are rendered more effective or easier by treating fragment grid and frame grid as independent values, but, nevertheless, for each fragment the frame grid is aligned to the respective fragment's beginning. A compression effectiveness lost may be kept low when appropriately selecting the fragment size. On the other hand, the alignment of the frame grid with respect to the fragments' beginnings allows for an easy and fragment-synchronized way of handling the fragments in connection with, for example, parallel audio video streaming, bitrate adaptive streaming or the like.Type: ApplicationFiled: August 9, 2023Publication date: November 30, 2023Inventors: Bernd CZELHAN, Harald FUCHS, Ingo HOFMANN, Herbert THOMA, Stephan SCHREINER
