Hi,
I have 2 questions which I hope somebody can help me :

Question 1 :
Is it possible to define the playback duration of each of a mms message component?
for example, if a mms message contained 3 components in the following sequence, a text message, a picture, and finally an audio file. Is it possible for me to define the playback duration of the 1st component to be 5 seconds, the playback of the 2nd component to be 3 seconds and the playback of the 3rd component to be as long as the audio file playback.

Right now, the playback duration of such a mms message in my test phone (nokia 3200) is as follow :
- text message : 1 second
- picture : 10 seconds
- audio file : as long as the audio playback

I would like to program the text message to be displayed for 2 seconds and the picture for 5 seconds. Is this possible?

Question 2 :
I realised that the picture been displayed had shrinked proportionally. When I open the picture separately (ie not part of the mms presentation), the picture is in the correct size. Is this being controlled by a SMIL file. If yes, where can I re-program it?

thank you

best regards
david

Hi David,

1.) Include a SMIL file in your MMS content. The "dur" attribute of the "par" element specifies how long that page is to be displayed. There's a real simple SMIL example in the following thread: http://support.nowsms.com/discus/messages/485/5962.html

2.) It might be. How exactly are you sending the message?

What is the SMIL you are including?

It might also just be a quirk in how your phone displays presentations.

Hi Bryce,
Thank you for the SMIL thread and sori for the late reply. We were celebrating Chinese New Year

Anyway, with regards to your reply to my first question; what you are saying is that nowsms does not automatically generate a SMIL file when it deliver a mms message via GPRS modem connection to the telco, rite? If this is the case, then how do I include the SMIL file into my mms message?

As for your question, I tried another 2 different models, nokia6610 and SE T610, both displayed the same problem, ie a smaller animated picture at the top left hand corner, as the nokia 3200. In addition, I did received a mms message from my telco (part of their A&P campaign) on my nokia 3200 and their animated picture was displayed in the correct size.

I used ASP scripts to compose and submit my customer mms messages to nowsms. I have a direct GPRS modem connection to my telco ( I believed this is called MM7 connection, correct me if I m wrong).

Thank you

best regards

Hi David,

Well, Happy New Year then!

You simply include the SMIL file as one of the pieces of content. (Make sure to give the file a ".smil" extension.)

SMIL is an optional component of an MMS message. Basically I describe it as a "slide show presentation language" that controls the display of slides of the message.

The type of connection that you are using to the mobile operator is MM1. And the behaviour that you describe seems very odd to me. Try adding a SMIL file, and let's see if that makes a difference. I don't see why it would make a difference, but let's try that as the first step.

If that doesn't change what you're seeing, then I'll have to give it some more thought.

Hi Bryce,
Thanks...holiday over now :-(

I used the nowsms web interface to send the following SMIL file to my phone :

<smil>
<body>
<par dur="5000ms">
<text src="http://x.x.x.x/sample/test-text.txt"/>
</par>
<par dur="10000ms">
<img src="http://x.x.x.x/sample/samplegif.gif"/>
</par>
</body>
</smil>

I received a blank message with a total playback time of 14 seconds. I can see the timer count down and when it reached the 9th seconds, the display scroll down and the timer continue its count down. It appeared that I can received the SMIL file and the phone can understand it. I assume that if I include a SMIL file, I need not include the actual gif or text files. Is my assumption correct?

Lastly, I tested the above on a nokia 3200 and a SE T610. Both gave me the same results.

Where did I go wrong?

thanks

regards
david

Hi David,

Sorry, I was busy with 3GSM last week and have struggled to get caught back up.

Where you went wrong is that current generation MMS clients do not support external links from a SMIL file.

They expect the "src" reference to point to another object that is embedded within the multipart MMS message.

Hi Bryce,
I guess as much.

Anyway, I tried with the same mms with all the necessary objects embedded. The mms presentation was still blank and the embedded objects appeared as attachements ie, after the blank playback had finished, i need to manually scroll down before I can see the objects.

If I did not include a SMIL file, all the embedded objects appeared as part of the presentation. BTW, I used the nowsms web-interface to test all these mms.

Where else did I go wrong?

Appreciate your assistance

thanks

David,

Put the files that you attempted to send into a ZIP, and upload them as an attachment here. Then I'll try sending them and take a closer look.

Make sure that the SMIL file has a ".smil" extension, because that is the only way that we can identify the file as such when it is uploaded via the web interface.

David,

And apoligies for my delay as well.

Remove the "http://x.x.x.x" from the SMIL.

It should just be:

<smil>
<body>
<par dur="5000ms">
<text src="test-text.txt"/>
</par>
<par dur="10000ms">
<img src="22000001-web.gif"/>
</par>
</body>
</smil>
