现有技术中的多媒体即时通讯主要应用在个人电脑 （PC , Personal Computer )和智能移动终端设备上， 例如 PC和 PC之间进行的音频通话、 视 频通话和文本聊天等。  The multimedia instant messaging in the prior art is mainly applied to personal computers (PCs, Personal Computers) and smart mobile terminal devices, such as audio calls, video calls, and text chats between PCs and PCs.
目前， 各种即时通讯都使用各自所特有的私有协议， 很难互联互通， 例如 使用 PC进行文本聊天时， 如果进行聊天的对象分别存在于两个客户端软件的 通讯列表中， 就需要在 PC上同时运行这两个不同的客户端软件， 并通过各个 客户端软件特有的操作规定，来获知进行聊天的对象当前的状态，如是否在线、 是否能否接收传送的文件等。  At present, all kinds of instant messaging use their own proprietary protocols, which are difficult to interconnect. For example, when using PC for text chat, if the chat objects exist in the communication list of two client softwares respectively, it needs to be in the PC. The two different client softwares are run simultaneously, and the current state of the object to be chatted, such as whether it is online, whether it can receive the transmitted file, etc., is obtained through the operation rules specific to each client software.
可见， 目前的多媒体即时通讯一方面可应用的设备较少， 另一方面在硬件 资源受限的嵌入式设备， 例如机顶盒上， 同时运行较多的客户端软件， 会耗费 较多资源， 操作也很繁瑣。  It can be seen that the current multimedia instant messaging has less devices to be applied on the one hand, and on the other hand, embedded devices with limited hardware resources, such as set-top boxes, which run more client software at the same time, consume more resources and operate. Very cumbersome.
