But commercial approaches are preferred by certain multimedia big enterprises. These enterprises dominate the mobile media delivery business.

We will give our vision on: Real Networks’ Helix Media delivery components based on RTSP and Microsoft’s IIS Media Services based on HTTP. The aim of this book chapter is to provide detailed insight into these different streaming approaches and how these platforms and protocols aid in building flexible streaming applications for mobile devices. A comparison among these approaches is also provided and also we present the delivery of video streaming to Apple mobile devices in the two commercial approaches.
