• Peer-to-Peer Video Streaming Basics

• Comparison,Classical & Peering Methods

• VideA Platform Capabilities

• The End

Internet Video Streaming

• Voice and video of a content is loaded onto IP-UDP packets and sent over the Internet.

• The content may be a live TV broadcast, a film on a DVD or an episode of a favorite show, etc.

• The receiving party displays the content of the packets as they are received.

• It is not download and watch/play.

Examples

• Microsoft Media Server & Player

• Real Media Server & Player

• Apple Quicktime Player

• Flash Player

• VLC Media Player etc...

Disadvantages

• Bandwidth required on the service provider side is very high.

• CAPEX & OPEX for this high bandwidth avoids video services reach high number of end users.

Advantages of Peering• Peering Technology aims to utilize

the unused bandwidth available on the Internet.

• Clients act as servers & forward the content they receive to other clients requesting the same content.

• Load is distributed among the Internet.

• Number of concurrent viewers is not directly limited by the server bandwidth.

VideA

Compared ToClassical Approach

• To serve the same number of clients, much smaller Internet connection is enough.

300Mbit 6Mbit Metroethernet downgrade

means 92% cost reduction in OPEX.

• At a given bandwidth, more viewers can receive the same content.

With a 300Mbit bandwidth, instead of 1000,

an estimate of 50,000 end users can be reached.

Additional Advantages

• Traffic Shaping according to the transmission media charecteristics, say ADSL or WLAN.

• Traffic Bandwidth Management to fit tightly into a given maximum bandwidth.

• Mobile device & WIFI support.

• Open Protocol support and interoperability.
