H.248协议

H.248协议,也叫MeGaCo协议,是媒体网关控制器(MGC)与媒体网关(MG)之间的一种媒体网关控制协议,这个协议是一项ITU-T与IETF合作结果的新标准。目前ITU-T、IETF、软交换论坛等标准化组织正在加紧对H.248协议进行完善,各大电信设备制造商也在H.248协议的研发和应用上加大了投入。与MGCP协议相比,H.248协议可以支持更多类型的接入技术并支持终端的移动性,除此之外,H.

为什么叫H.264 H.264是一种视频高压缩技术

为什么叫H.264 H.264是一种视频高压缩技术,全称是MPEG-4 AVC,用中文说是“活动图像专家组-4的高等视频编码”,或称为MPEG-4 Part10。它是由国际电信标准化部门ITU-T和规定MPEG的国际标准化组织ISO/国际电工协会IEC共同制订的一种活动图像编码方式的国际标准格式,这是我们叫惯了的MPEG中的一种,那为什么叫H.264呢?
