A method and an apparatus for converting a moving picture expert group (MPEG) media transport (MMT) stream into a MPEG-2 transport stream (TS). The method including applying restrictions to MMTP packets for the MMTP stream. The method also includes converting a presentation time and decoding time from a coordinated universal time (UTC) based absolute time to a program clock reference time (PCR) based value. The method further includes, when converting the MMTP stream to the MPEG-2 TS, constructing the MMTP stream based on MPEG-2 TS rules without adding or removing data by using a hypothetical receiver buffer model (HRBM). Additionally, the method includes determining values of MPEG-2 TS packet fields of a TS packet layer, an adaptation field and Packetized Elementary Stream (PES) packets from values of the MMTP packets. |
