What is the relationship between Microsoft Windows Media Technology and MPEG-4?
According to Microsoft. MPEG-4 builds upon the work of MPEG-1 and MPEG-2. It defines a new authoring and delivery paradigm that extends beyond the current model of compressing and delivering rectangular video over homogeneous networks. MPEG-4 is a set of specifications for authoring object-oriented, nonrectangular interactive objects and scenes, and delivering these independent layered objects over heterogeneous networks by using network streaming protocols. It also defines how to render and present these scenes dynamically, similar to how the Web works today.While MPEG-4 does not specify digital rights management (DRM), it does define hooks to proprietary DRM systems and many other areas. Microsoft and MPEG-4 Many companies have contributed to the development of MPEG-4. Microsoft has also been a supporter of this development process for some time, particularly in the video area. Microsoft has made more than 100 formal contributions to the MPEG-4 standardization process and has patents
