In contrast, UPnP streaming normally uses buffering in the renderer, which would make the real-time capabilities of RTP redundant for this usage. We may both be getting muddled (my fault, I fear). My understanding now is that RTP/RTTP is a transport layer protocol, and so is a counterpart to TCP/IP rather than HTTP. TCP/IP is documented as being unsuitable for real-time use (as it favours reliability over timeliness), so, if UPnP actually runs in HTTP on TCP/IP (I haven't managed to check that point), you can see the need for buffering. I think I'm in danger of going off topic, so I'll leave it there. David |
