ITU-T H.262 (02/2000)

信息技术 — 活动图像和相关的声音信息的一般性编码：电视

本建议书定义了一些H.248.1包用于媒体网关，这些包被设计用于支持H.323终端和H.324终端之间的互通。更明确地说，本建议书包含："h324"包用于创建支持H.324的终结点；"h245"包用于创建支持H.245通道的终结点，H.245通道用于支持H.324呼叫；"h323bc"包用于创建支持H.245通道的终结点，H.245通道用于支持H.323呼叫；"h245com"包用于MG与MGC之间的H.245命令的通信；"h245ind"包用于H.245指示的通信。
注 — 本建议书已重新编号。本建议书以前称为ITU-T H.248建议书附件M4。
