Hi all,

Greetings!

I am developing a desktop MMS Editor in VC++ which will create MMS messages which i will later transfer to my mobile phone using bluetooth, IR and then send the MMS message to any recipient phone.

While saving the MMS message in the hard disk it is saved as .mms using SMIL for presentation as per the Wireless Session Protocol (WSP).

But I am not clear about the MMS Header Encoding mechanism used.

From the research I have done as yet...I have discovered that there is some binary encoding mechanism used..but am not quite sure about how and what, in the sense is there any methods in the MFC...or if there is particular format...?

I am also attaching alongwith an .mms file which I created with the Nokia Developer Suite for MMS

<smil xmlns="http://www.w3.org/2000/SMIL20/CR/Language">

<text region="id_4766FED2" src="dancing_mouse.txt" end="5s"/>
</par>
</body>
</smil>
*********************************************

Like u saw...before the start of the <smil> tag...there is some junk character with the MMS headers such as

From:
To:
cc:
bcc:
Subject:

all the above values are encapsulated within a lot of junk values...which i understand here is the encoding! ..and it wud be fab if any one of you out there cud tell me wat is the encoding mechanism used and how this encoding is done...!

Any advice, insights, suggesstions would be great!

Thanks,
Best Regards,
LearningCurve.

Hi Siddartha & Ratish Kumar,

Please follow MMS, WSP and WTP protocols in detail from http://www.openmobilealliance.org/tech/affiliates/wap/wapindex.html

MMS is layered on WSP and WSP is on WTP.
WSP - WAP Session Protocol
WTP - WAP Transaction Protocol

Hi there

Can anyone provide me some information on MMS over IP not WAP.

I will be thankful if you can provide information for MMS Encoder and decoder format over the IP not WAP.

Thanks and regards
