You will also need a "depacketization" component - one for RealAudio and one for RealVideo. The RA depacketization takes packets and deinterleaves them. The RA depacketization takes packets and re-assembles encoded frames. > > [2] For this kind of applicatoion, is Operation system necessary? > Well, some basic functionality is obviously necessary. For the .rm format reader, you have to have some kind of file reading capability. For any of the rest, you have to have memory allocation capabilities. For video, you clearly need some kind of video blitting capabilities.
