标准摘要
[中文适用范围]： 本部分IEC 62766规定了通过HTTP进行自适应单播内容流媒体的媒体格式。 规定了两种HTTP自适应流媒体格式。第一种完全基于MPEG DASH。第二种是基于3GPP第9版自适应HTTP流媒体(AHS)格式的OIPF“HTTP自适应流媒体”(HAS)格式，并添加了媒体组件功能和MPEG-2传输流内容段格式的支持。后一种格式在MPEG DASH发布之前就已指定，由于在一些遗留应用程序中的使用而保留。 [外文原描述]： 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 “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.
