一、MMS的封裝(Encapsulation)——MIME對於使用SMIL語言描述的MMS,在通過無線網路發送的時候,我們必須通過某種方式把SMIL和附屬的內容封裝在一起,一邊能夠以一個unit(整體)的形式發送出去,以便SMIL檔案各個部分內容的reference變得有效。這個解決的辦法就是MIME(Multipart Internet Mail Extensions)規範,這個規範的最初作用是在email的plain text的主體中加入不同的內容。比如說,發送帶有附件的email,這個時候

一、概述MMS多媒體訊息大家都看到過,或者都編輯過。在這裡,利用一系列的文章來說明多媒體訊息的編輯、發送和接收的過程。首先這裡,簡單描述一下多媒體訊息的編輯過程。這是多媒體訊息的第一步。二、MMS的表述(presentation)語言——SMIL概述MMS由一系列類似於“power point style”類型的slide組成,由這些slide來組織各種格式的文本、音頻、視頻資訊。這些我們在發送或者接受多媒體訊息的時候都有切身的體會,就不說了。為了把這些多媒體資訊組織到一起,通過網路發送,並且這
