Abstract
Moving Picture Experts Group (MPEG) media transport protocol (MMTP) content is received from a source of content such as an ATSC 3.0 source. The MMTP content is used to construct as a Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH) files. Constructing the file includes writing media processing units (MPU) header data, fragment header data, and MPU data. Constructing the media files also includes accounting for discarded Fragment Type 3 data in relation to a media data (MDAT) section of the DASH media files. Further, constructing the file includes appending digital rights management (DRM) data to the DASH MPD file. After the file has been constructed, a DASH software media player can play the media content using the file.
