Our Research

Recognizing the opportunities offered by object oriented multimedia compression algorithms (specifically MPEG-4), we have developed an MPEG-4 Streaming System that provides a flexible platform for developing internet capable streaming media applications. Our research efforts have been concentrated in the following directions:

• Delivery Multimedia Integration Framework (DMIF) standard conformity
• QoS capable multimedia server (Yaser)
• Multicast enabled DMIF instance (Kambiz)
• MPEG-4 broadcast system (Amr)

The MPEG-4 Streaming Server operates ideally on the WinNT,Win98 and Win2000 platforms. 

For more information on MPEG-4 and the DMIF layer, please visit the www.cselt.it/mpeg/ web site. This site provides many useful pointers to MPEG-4 related web resources. For further information about MPEG-4 tools visit our links site.

Announcements, What's New:

November 30, 2001: 

Additional information on how to use IM1 with our Streaming System is found in this document : m7668.htm ( Implementation of MPEG-4 DMIF Remote Retrieval Instance and Streaming Server, Contribution document sent to the 58th MPEG meeting). 

July 11, 2001: 

The source code of our MPEG-4 Streaming Server is now downloadable through IM1 ftp site (password protected). Look under UBC directory in IM1 folder.

May 29, 2001 : 

You can find more information about our systems (remote retrieval and broadcast scenarios) in our paper that has been published in the 11th Packet Video workshop (PV2001) : "MPEG-4 streaming over IP and Broadcast Networks: DMIF based architectures" (pdf). 

March 6, 2001: 

        The source code of our MPEG-4 streaming server has been contributed to IM1 and will become available to MPEG-4 community.

        Download the supplementary documents : MPEG-4 Streaming System (pdf)

February 21, 2001:  

         The first version of our MPEG-4 Broadcast Server has been released

Download Server Executable Here

The Source code for "DMIF instance for Broadcast"  has also been released, to download the code please see the download instructions below.

February 15, 2001: 

        A new version of our MPEG-4 Streaming Server (Remote Access) has been released. 

        This version of the Server has been tested with IM1-2D  5.3 and our DMIF remote retrieval instance. 

A graphical tool for monitoring outgoing traffic has been added to the server, Using the new user Interface, the user will also be able to set a few control parameters that allow for:

        1.  Controlling the outgoing rate by randomly dropping a percentage of media packets.

        2.  Controlling the fast-start technique parameters to fit client's media buffer size.

How to get the Software:

The only software module available on this site is the implementation of DMIF Instance for Remote Retrieval. Click here to be redirected to the download page.  The server source code is not provided in this site.

To get our Server Source code and IM1 client application source code please refer to the IM1 ftp site or MPEG official site. These sites are password protected. 

If you have access to MPEG Username and Password follow this link: "MPEG members only". But if you don't have access to IM1 software or site, you won't be able to download the Server source code.

Installation Instructions:

  MPEG-4 Streaming Server

• Extract the files for the MPEG-4 Streaming Server to any directory
• Run the \<extracted directory>\server.reg to add the required information to the registry
• You can run the server by double clicking on ApadanaServer.exe
• Create a directory "ESResources" and store the .mp4 files that you want the server to stream in that place..

 DMIF Instance for Remote Retrieval (used in conjunction with IM1 software)

• Extract the DMIF Instance for Remote Retrieval files to \IM1-2D \DMIF\
• Add the RemoteInstance project file (*.dsp) to the IM1 workspace
• Make RemoteInstance project dependent ( project > dependencies ) on ZTL and SL_MPEG4 projects.
• Run the \_Registry\remote.reg file to add the required information to the registry

MPEG4 Broadcast Server: 

• Extract the contents of the zip file into a directory
• Run the server.reg file to install the registry entries required for the server
• Run the executable MPEG4BCServer.exe

DMIF Instance for Broadcast (used in conjunction with IM1 software)

• Extract the DMIF Instance for Remote Retrieval files to \IM1-2D \DMIF\
• Add the BroadcastMP4Instance project file (*.dsp) to the IM1 workspace
• Make BroadcastMP4Instance project dependent ( project > dependencies ) on ZTL project.
• Run the \_Registry\new_im1.reg file to add the required information to the registry
