Hi, We did some experiments comparing TFRC, playout delay reporting, TMMBR in a 3G environment. The experiments were done in ns2 where we implemented a 3G link and an interface to hookup a real encoder to pass video frames to and from ns2. The paper was published in a workshop co-located with INFOCOM. The main metric we used was PSNR. Both endpoints in this case were 3G endpoints and had different throughput in their cells. The link to the paper is: http://www.netlab.tkk.fi/~jo/papers/2009-04-movid-3g-rate-adapt.pdf On Tue, Apr 17, 2012 at 10:16, Michael Welzl <michawe@ifi.uio.no> wrote:
Hi,
I noticed that TFRC is, well, unpopular here. I understand the reasons, in particular the group's desire to minimize buffering. So I'm not making a proposal here, just asking a question out of academic curiosity: is this just handwaving and assumptions, or have some people given it a try and found that it doesn't work well? Are there any documented results showing that?
I think someone posted earlier on that there were poor experiences with TFRC; I'm just interested in more details about that. Again, I'm not proposing anything here, just interested for my own research.
Cheers, Michael
