PowerMedia HMP 4.1
Dialogic® 主机媒体处理 (HMP) 软件 4.1LIN 版本, 是构建创新的语音和视频解决方案的高密度媒体处理软件。HMP 4.1LIN版本所支持的多媒体特性包括: 视频编码转换 (支持H.26/H.264和MPEG-4标准)、视频速率转换、召开视频会议, 以及支持 3G-324M (MONA和WNSRP协议)。Dialogic HMP 软件 4.1 版本也支持音频编码转换 (协议AMR-NB、G.723.1、G.729a、G.729b、G.726 和 G.711 [G.722 和 AMR-WB/G.722.2、原始流、原始播放/录制、安全特性, 以及通过 Dialogic HMP接口卡 (DNI卡) 与 PSTN 连接。

Dialogic HMP 软件 4.1 版本为每个系统提供了具有语音、视频、对话、T.38 传真和会议等资源的并发音频会话, 也提供了并发的多媒体会话, 以及采用音频和视频转码的高级视频会话。因为主机处理能力不断增加, Dialogic HMP 软件能够支持的并发会话的数量也随之增加, 所以 Dialogic 不断对新处理器的能力进行测试, 并将 Dialogic HMP 软件的最新密度测试结果发布到 Dialogic 网站。最新结果显示, Dialogic HMP 软件 4.1 版本能够成功支持多达 5000 个 SIP 媒体会话。密度和扩展性受到具体应用以及使用中主机处理器能力的限制。
