IEC 62766-2-2:2016 specifies media formats for adaptive unicast content streaming over HTTP. Two HTTP adaptive streaming formats are specified. The first is based entirely on MPEG DASH. The second is the OIPF \u201c HTTP adaptive streaming\u201d (HAS) format, which is based upon 3GPP\u2019s release 9 adaptive HTTP streaming (AHS) format, with some profiling and extensions to add the features of media components and support for MPEG-2 transport stream content segment format. The latter format was specified before MPEG DASH had been published. It is retained due to usage in some legacy applications.<\/p>\n
