Windows Media Mobile Technology
Broadcast and Live StreamingYou can build a mobile media solution using Windows Media mobile technology that enables your subscribers to view broadcasts and live streaming content. Subscribers can search for and play video broadcasts that are streamed to their handsets in real time. In addition, broadcasts can contain interstitial ads inserted by the mobile service provider that can even be personalized for the subscribers.
The broadcasts may be delivered using digital mobile broadcast technologies that can provide more reliability and lower power demand, such as Digital Video Broadcasting: Handheld (DVB-H), Digital Multimedia Broadcasting (DMB), Terrestrial Integrated Services Digital Broadcasting (ISDB-T), and Digital Audio Broadcasting (DAB). The content can also be streamed to handsets over a traditional wireless data network.
How It WorksContent providers encode the live video by using Windows Media Encoder 9 Series and the stream sourced by a Windows Media server. The stream is then delivered to the handsets over the air using a technology such as DVB-H, or using Windows Media streaming over the wireless data network. Subscribers receive the stream on their handsets, which decode the data with the Windows Media Audio 9 and Windows Media Video 9 codecs.
The following tables describe the service and mobile device components you'll need to create a broadcast or live streaming.
