structure of media object (MMS body)?????

[alinesimon]

Hi,

I don't understand the structure of the MMS body.
A MMS (according to the specifications) is composed of :
MMS Header | MMS body

What the MMS body id defined?
If I have 4 media objects (smil presentation, a gif, text, arm),
What the MMS body is organized?
In the WSP specifications, it explains the structure of multipart data.
Have I to use this structure in order to declare the media objects?
Is it necessary to define the headers content-type, content-ID, content-location, and X-Wap-Content-URI for each media object?
What is exactly the structure of the media object?

Thanks for your help
charly

you are right. MMS body consists of multipart data. It conforms to RFC
2387.
also you could go through WAP-209-MMSencapsulation document from WAP Forum which will give you good insight.
Also refer to "How To create MMs service" by nokia forum.
MMS header will contain content-type field. this will be set to application/vnd.wap.multipart.related,if MMS contain SMIL data. Otherwise, content-type will contain application/vnd.wap.mixed.

Each of the media object will be placed in the MMS body in conformance with multipart structure.

for eg:- here is a small MMS PDU

MMS Header will contain fields and value like:-

From : +123/TYPE=PLMN
To: +134/TYPE+PLMN
Subject: test message !
content-type:application.vnd.wap.multipart.related;
type="application/smil";
start="<0000>"

MMS Body will contain fields and data like:-
content-type:application/smil
content-ID:<0000>

here smil data will be there....


content-type:image.gif
content-ID:<xyz.gif>

image data..............

Each of the image object will be sepreated by boundary(delimiter) mentioned as one of the fields in the body.

you will get a better idea once you go through "How To Create MMs service" by nokia forum.
