As the 3G network grows and deals are signed across Europe, 3GPP will
become the dominant format for rich media distribution to mobile devices. Streaming Video has been developed from the beginning with the needs of the wireless operators in mind:

• It comes out-of-the-box as a fully clustered system. No need to engage
  with systems integrators to build the clustered solution and integrate it
  with your legacy environment.
• It addresses the bandwidth variation aspects of the wireless networks
  in a way that makes sense in the cellular domain - it is client agnostic!
  The operator can deploy handsets with different client players, and
  indeed even support handsets that are roaming-in on its networks.
• Developers of hundreds of existing multimedia authoring applications
  can inherit 3GPP and 3GPP2 functionality for their products
• It is able to transcode and stream between all the different
  3GPP/3GPP2 audio and video codec, including Windows Media
• Content creators already using MPEG4 based video can easily deliver
  media to a whole new audience via new, high-speed wireless
  networks.
