But now because of simplicity of HTTP, HTTP come > again for streaming. We know this is HTTP "Second Spring" > So Flash player now become more popular than Real player and Media Player. But we know RTP protocol is very friendly to streaming content chunk. > So, If we design RTP to HTTP Gateway, we should consider how to utilize the existing advantages of RTP over TCP. [Qin]: I am not sure we need to build such Gateway. The motivation to look deep into it is how to introduce multicast support for HTTP streaming. One existing protocol we may look at is RTMP, one of features in RTMP is multicast support. >>case 3: "Multi-Screen" Service Delivery >>case 4: Heterogeneous Handover >>Hope it helps get a better understanding what the scenarios may may look like. If anybody would like to contribute to use case document >>or provide more input, that will be great. >>_______________________________________________ >>httpstreaming mailing list >>httpstreaming@ietf.org >>https://www.ietf.org/mailman/listinfo/httpstreaming > > = = = = = = = = = = = = = = = = = = = = > > > > ZhiHui > > Tel:021-65107607,65643187 > Fax:021-65647894 > Mob:13818168919 > 2010-10-12 >
