Joint Activities

The Composite Media Group has engaged in joint activities as part of our MPEG-4 project work. This section lists the work by location and in doing this we would also like to give due credit for both the work and technologies from these groups that have gone into and enhanced our work. For more information please contact us or contact a person in the group with whom we have been working.

The Yorktown group developed native, cross-platform, C code for MPEG-4 video decoder and AAC audio decoder. We have used this code as a base and created native dlls that our MPEG-4 Java Toolkit components can use to achieve higher performance. We have these dlls in Windows, Linux, OS/2 and WinCE versions.

The Haifa group developed a pure Java MPEG-4 video decoder and a pure Java MP3 audio decoder. They also have a native code version of their MPEG-4 decoder. We have integrated these Java decoders into our Toolkit and we also have dlls based on the native MPEG-4 code, again in Windows, Linux, OS/2 and WinCE versions.

The Tokyo group has been engaged in activities in the wireless area and we have contributed our technologies MPEG-4 for their activities and joint research with NTT Docomo. This includes technologies in support of adaptive streaming and seamless drop-out recovery for MPEG-4 video and AAC audio, including technology in compliance with 3GPP for streaming AAC audio. Seamless roaming between 3G wireless and 802.11 wireless LAN networks is a current area of joint activity.

We have developed an ISMA compliant MPEG-4 Java applet player which has now been shipped as part of IBM Content Manager Videocharger 8.1 release. Another group in our department is focussed on multimedia servers and jointly we have provided technologies in support of MPEG-4 enablement for VideoCharger.
