BS EN 62766-2-2:2017 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 "HTTP adaptive streaming" (HAS) format, which is based upon 3GPP's 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.Cross References:EN 62766-1ETSI TS 101 154:2012ISO/IEC 13818-1:2015IEC 62766-2-1:2016IEC 62766-3:2016ISO/IEC 23009-1:2014IEC 62766-5-1 Ed.1.0IEC 62766-4-1 Ed.1.0ISO/IEC 23001-7:2015 ED2IEC 62766-7 Ed.1.0EN 62766-3:2017ISO 639-2:1998 (R10)EN 62766-2-1:2017IEC 62766-1:2017ISO/IEC 14496-12:2015IEC 62766-6 Ed.1.0ISO 639-3:2007 Ed 1 (R10) IETF RFC 2630ITU-T Recommendation H.262All current amendments available at time of purchase are included with the purchase of this document.
