[Stremes-l] bandwidth

Hi Helen and Ken,
Great to have a list to focus in on the complexities and challenges of online performance. Big thanks to Ken for setting this up!!
Regarding bandwidth, I learned a lot in my recent discussions with Furtherfield regarding the idea of “social broadcasting.” Although our TV project is on hold for now (lack of funds), we explored how a community of artist-broadcasters can collaborate despite varying Internet access and technical capabilities. In other words, how can someone with nothing more than a cell phone on a cellular network, or an IP phone, or a laptop with basic wireless coordinate with someone like Ken who uses IPV6 on a university network. I have been exploring cloud-based solutions such as Wowza, which will accept any type of transmission and transcode it for distribution/broadcast to the networked audience.
It’s all still theoretical as I haven’t yet begun working with their service, but I did have my students create a broadcast channel this past semester and we were able to use Skype, Periscope.tv, and cellular broadcasting and aggregate the transmissions using Wirecast, which is effective in rebroadcasting out to the Internet. Achieving the flexibility of artists able to collaboratively network and broadcast within their constraints is an interesting and I think important challenge in opening up live networked performance to a wide range of artists and audiences.
Best, Randall

hi ken (& list),
yes indeed, audience accessibility has always been very important for us with UpStage; for a long time we had artists & audiences who were on dial-up & had no possibility to get broadband where they lived - & now we get people on unstable mobile networks, which is another story.
& our streaming is also at the low end of things; we have just had a show that had 4 webcams streaming together through UpStage, & we did (as always) have some issues with lag but apart from that it functioned pretty well. not HD, nor stereo uncompressed audio, but creative communication :)

Hi Helen,
The extra headroom of university grade networks (1gig) mostly helps
with multiple HD video streams. Stereo uncompressed audio can
be done on less than 10M (up and down) with one or two people.
However, I assume your feeling of being bandwidth challenged is
not just about paying for a premium bandwidth package yourself,
but that your practice is based around audience participation
and the low-data server based platform you guys developed -
as well as the aesthetic that emerged as a consequence.
We all have different situations. CERNET2 in China (china edu research
network) is ipv6 only. I’m ’stuck' on next generation networks without
much of a real internet (blocked). So my practice is heavily P2P
with whoever can negotiate IPV6 upgrades with their IT depts.
Anyway, we’re probably just around the corner from ubiquitous
ipv6 1 gig bandwidth for everyone - thanks to google fibre pushing
the competition. Then in the future, we can all get nostalgic remembering
how we could possibly have survived in the good old days with only 1 pitiful
gig of bandwidth - when data crawled along at a speed significantly
slower than the speed of light.
Ken
