Sorry, to be clear, the FCC concern I consider here is limited to live streaming scenario. -----Original Message----- From: httpstreaming-bounces@ietf.org [mailto:httpstreaming-bounces@ietf.org] On Behalf Of Ning Zong Sent: Wednesday, October 20, 2010 4:50 PM To: 'Ali C. Begen (abegen)'; 'Roni Even'; 'David A. Bryan'; 'Qin Wu' Cc: httpstreaming@ietf.org Subject: Re: [httpstreaming] Current Status and Our Goal IMO, the issue may not only related to multicast or unicast, but the QoE improvement (e.g. reduce the startup time after user change the channel). If I remember correctly, in the motivation of FCC in AVT, one important concern is that the Retransmission server can store the most recent GoPs and feed them to the client with faster rate than playback to effectively fill the gap between the time point of user channel zapping and next complete GoP. This improvement also applies to unicast based HTTP streaming, right? The above concern also implies that adding some intelligence to intermediaries would improve the streaming performance of HTTP streaming system. To be more specific, having a deep look at the mechanisms of distinguish different types of HTTP traffic (e.g. live streaming with higher timing requirement v.s. normal packet, streaming packet containing I-frame worthy of caching for further usage v.s. normal streaming packet) would be a possible direction for consideration in this list. My two cents. BR, Ning Zong -----Original Message----- From: httpstreaming-bounces@ietf.org [mailto:httpstreaming-bounces@ietf.org] On Behalf Of Ali C.

Address the startup issue, we have worked in AVT on fast channel/content > change and I think this is relevant also in this case. Are you assuming a multicast environment for http streaming? Ow, the startup issue is not an issue in unicast connections. -acbegen _______________________________________________ httpstreaming mailing list httpstreaming@ietf.org https://www.ietf.org/mailman/listinfo/httpstreaming _______________________________________________ httpstreaming mailing list httpstreaming@ietf.org https://www.ietf.org/mailman/listinfo/httpstreaming
