I am new to the DMM/DMP suite so bear with me.
Through an http client I need to be able to display text on a series of DMPs. The text will vary each time I want to display it and each DMP might get slightly different text.
This of it like this:
One day the message might be: "Happy Birthday Bob", the next day it might be "Donuts in the Breakroom". The general display would be the same, jus the text would change.
 
As I understand the DMM/DMP suite I could do the following through the rest API.
1) create an asset on my client for each message.
2) upload the asset to the DMM
3) create a playlist and assign the asset uploaded in step 2 to that playlist
4) tell the DMM to activate the playlist just created to whichever DMPs I desire.
 
I'm quite certain this will work, but it entails publishing a lot of stuff that will only be useful for the duration of the playlist which may only be a few minutes. At that time I now have a cleanup issue to get rid of these assets that will never be used again. I can certainly do it through the rest api, but it seems like a lot of housekeeping.
 
What I would like to do if possible is the following:
1) Create one playlist through any mechanism desired.
 
Then when I need to display the playlist on some DMPs just tell the DMM, through the REST api, to display it and, oh by the way, here is some extra text I want you to display within the playlist (Bob's Birthday, or Donuts in the Breakroom).
 
This solution would have the advantage of not having any content to really manage. It's just the one playlist. It would also still be able to take full advantage of the DMM's management capabilities.
 
I've been able to do something similar to this by uploading an html page with javascript in it that can read query string parameters to the DMM then I tell each DMP through the :7777 port set_param= to tell the tvzilla browser to load this page and I pass in the extra arguments. This technically works, but I lose a lot of the management capabilities of the DMM, (specifically surrounding emergency messages).
 
Is there a better way to do this?
 
Is there something I am missing entirely regarding the existing functionality in the DMM/DMP suite that makes this task much simpler than I am grasping. That wouldn't surprise me given the spartan developer's documentation I have found to date.

i need to do the same of above,,, and i understand the way on HTML, but here i m using the 4310 DMP, so wht's the solution for this???

then you can biuld a playlist for each zone..

Yes, there is a better way. You will likely have some standard content, put that in a playlist inside a presentation. When you want these custom messages to play add an item that points to a web service like- http://internal.mycompany.com/myserver/todaysmessage.php (or asp, cgi, etc..)

At that URL you have built a web service that accepts the incoming request, processes any data necessary to make a decision and returns the appropriate piece of content. You will also need a front end for someone to define the messages and the rules that define when and where they will play. That might be as simple as an XML file or a more complex database, its up to you.

There are some slight variations in the exact methods you will use based on which player you have. The 4400 is a little different from the 4310.
