Future for internet streaming media Adolfo M. Rosas EU workshop January 19, 2010 Future research priorities in the Networked Media Systems research area Context Internet video & media streaming is a driving force for traffic consumption today. Video will be 90% of total internet traffic by (CISCO) Some commercial services were designed along the past 15 years to close the internet media gap: CDNs. Video & media objects have been small until very recently (2 years). Consumption of internet media has moved from downloads to streaming. Sudden availability of file sharing (P2P) created a video culture in internet. Some companies invested a lot to push this culture : Youtube. P2P file sharing and P2P streaming could not close the media gap. Commercial P2P services could not close the media gap. Telcos fight P2P: DPI, throttling, IPTV never made it to internet: now moving streaming protocols from complex to easier solutions. RTP+MPEG2TS+RTSP TCP+HTTP Premium media (BluRay, HD) out of the legal services in internet due to deficiencies in security and misalignment of majors and ISPs biz models. Internet media today works (barely) just because the pipes are big now but still dumb Short term There is a need to simplify the streaming media state of the art (mostly inherited from IPTV) to fit the internet. Must stabilise media transports : mapping any new coding schema (MPEG4AVC,On2VP6,) onto pure HTTP is a must. Correctly map scalable coding on the easy transports Investigate ways to provide QoS to internet HTTP flows end to end Evolve HTTP to be a suitable media transport Work to enable multicast safely on wide area multihomed networks Mid term Define schemas for the dynamic creation of media networks on top of internet : overlaid media networks. Build upon the work done by P4P and ALTO. Being able to interconnect dynamically CDN nodes from different owners is important P2P streaming has been a hot research topic, but much applied innovation is needed to create open services end to end. Content handling policies (including but not limited to access) must be made interoperable. Forget about CAS & DRM, implement open managed media. Long term Evolve the very internet fabric to content aware machinery. Evolution of IP protocols and the switching machinery is heading towards content aware routers and content aware IP stacks. It is key to have media transport supported natively by the network so no extensive planning needs to be done at the application layer (out of the network). Network should have the mechanisms to optimise the data paths and content delivery. Applications will be required only to especify a few QoS settings. There is a the need to create new business models for the consumption of internet media. We are at a serious risk of digital life monopoly by a few companies that ofer appealing media services.
