Technology for communicating Moving Picture Experts Group (MPEG)-2 streaming video quality information is disclosed. A network element can generate quality access units that are associated with one or more media access units in a media content stream representation. The quality access units can indicate quality metadata for the media access units in the media content stream representation. The network element can encapsulate the quality access units in an MPEG-2 transport stream (TS). The network element can generate a quality extension descriptor that describes the quality metadata indicated in the quality access units. The network element can communicate, to a user equipment (UE), the quality extension descriptor according to a defined periodicity. The network element can communicate, to the UE, the quality access units in the MPEG TS with the media access units, wherein the quality access units are interpreted at the UE based on the quality extension descriptor. |
