PPLIVE

Released in 2004 by “Bill” who dropped out of post-grad school in order to deploy software in dorms

Claims: Sept 2007: 3.5 million daily users Jan 2006: 400,000 daily users Weekly average usage time - 11 hours

Lots of foreign content [especially China]

PPLive limitations Findings show that PPLive peers are

“impatient” – only use pplive when actively watching.

PPlive now claims to provide DRM controls Questions for p2p streaming:

How to enable channel selection based on user interest?

VOD? Render multiple channels for simultaneous

viewing? Efficient media streaming?

RealNetworks: Adopting P2P No need for large scale server farms which

only get used a few times of year for rare and infrequent events

P2P accomodates popularity, flash crowds Bittorrent distribution and superseeding

have been shown to cause b/w cost savings Problems: Though superseeding saves

bandwidth, mean download rate was substantially lower.

How to scale iptv

How to distribute content? Data Centers? CDN’s? P2P was chosen, since it scales best to

‘flash crowds’ (ie: olympic viewership of 2.5 billion viewers)

P2P traffic will have more locality P2P transcoding P2P will become ISP friendly

Iptv operators want to…

Capitalize on the loading time for a channel during channel switch to provide ads

Recognize that most people who use IPTV do so while doing ‘other stuff’

A la carte pricing? [debatable]

IPTV-service operator conversation

Became very ‘animated’ when asked about thoughts on p2p streaming video and how it may influence his/her business

Conversation continued Observ.: Unlike Bittorrent, IPTV requires

minimum speed to operate Claims: Few peers have enough upload

bandwidth to support 2 or more peers Claims: more viable in other countries than

US, like Japan, Korea, Sweden DSL for home users goes to 700kbps-8Mbps Compared with 100Mbps in Japan/Korea and

even claimed 40 gigabits/s in Sweden Believes multicast will be successful in the

future
