Re: 2009 Regional Webcasts
We should also have a stream of FLR via the cable broadcast. It is done by a team alumni at RIT. Should have audio and video when it comes up.

Re: 2009 Regional Webcasts
I'm not sure if this was posted before, but anyone who is watching a regional webcast via ustream, please when you enter the chatroom set a nick name. To do this on ustream, type "/nick nicknameyouwant". Except remove the quotes. When I join I type /nick Joe_Widen This will make it easier to talk to people.
Thanks everyone. |

Re: 2009 Regional Webcasts
So far I have been less than impressed with the ustream.tv feed.
Any hope of getting some good webcasts??? |

Re: 2009 Regional Webcasts
NASA's offer to host any webcast remains open to those who wish to take advantage of it...

Re: 2009 Regional Webcasts
Regardless of the quality, props to all of those who make the effort to bring us these webcasts. Your efforts are greatly appreciated!!

One comment I recieved on the GSR webcast on ustream.tv was "wow, I can read the team numbers (at the bottom of the screen)". When transmitted at 350kpbs and utilizing a DV25 input stream the video was fairly decent. I pushed upwards of 450kbps uplink speeds, but downlink either due to ustream or local viewers networks (including my own monitor system at the event) showed jerkiness in playback. The main issue though is reliable uplink speed limitations. I had a 2000kbps uplink but still had problems maintaining streaming much beyond 350kbps. Throughput wasn't the only thing effecting streaming, latency was often as big an issue. I suppose a high-end hardware based realtime h.264 encoder might be able to achieve better streaming results with limited kbps bandwidth, but it all comes down to how many bits you can stream reliably and that is not limited by the remote server but is more effected by the uplink network in use. If NASA has an mms server then I'd like to do some trial broadcasts on it for next season. With an mms server I'd at least be able to choose my own codec, but I'd still likely use the MainConcept codec as used by Adobe FME as it is commonly on all recieving systems already although the CoreADVC codec is suppose to produce better run-time h.264 stream results (results were alot better than the x264 based FFmpeg tool chain in the latest 2009 streaming shootout). Thanks, bud PS by comparison the archived footage is being targetted at 1000kbps-1250kbps, or 3x-4x as much data. So there isn't a fair comparison between webcast and archived footage. I prefer 1600-2000kps archive footage, but then I have old eyes. (http://www.thenulldevice.net/Team0000/GSR2009/Videos/ - _540v are @1600kbps ~30MB/match and _720v are @2000kbps ~38MB/match these were converted from DV25 [25Mbps/~550MB file] snaps taken while webcasting).

Re: 2009 Regional Webcasts
Yeah, I mistakenly thought that was the one that Kiet Chau was hosting, but it was not. My apologies.

Re: 2009 Regional Webcasts
Attached are two net bandwidth snaps from GSR, one taken at the beginning of the day before everyone arrived with a lightly loaded network, the second at one of the low points during the day when I was struggling to maintain stream connectivity....
Any questions on why the stream was having problems? ![]() |

Re: 2009 Regional Webcasts
<off topic>
That's a pretty cool application. I just tested my connection at work, & it showed 58.1Mbps download, & 348kbps upload. What a crazy jump in values! I'll have to check my connection at home, just out of curiosity - I have cable there. Thanks for sharing! </off topic> |

Re: 2009 Regional Webcasts

Re: 2009 Regional Webcasts
Last I heard a local team/NASA would be webcasting SVR
