network traffic – consuming less energy and requiring fewer routers. Second, because private cloud fosters good behaviour. In the public cloud model, it is very easy to add resources (usually just a click away). This encourages waste. In the private cloud model, adding resources means buying, installing and configuring new servers. This tends to encourage ‘greener ’ behaviour. GOING FURTHER A private cloud deployment can still use huge amounts of resources. So we have developed solutions to reduce that. Highly efficient encoders – though perhaps priced slightly higher – are a responsible investment. Ours use an efficient encoding algorithm, which reduces by 20% the data that needs to be delivered every second for a given quality of image. When this is multiplied by millions of subscribers, and by the number of seconds in a day, the result can be a huge saving in terms of bandwidth – meaning less energy is consumed and fewer routers need to be deployed. Just-in-time packaging also significantly reduces the required content storage.

fluctuates, from huge numbers during a mid-afternoon sports final to almost zero at 3am. TV service providers generally deploy over-capacity so they can meet peak demands with high quality. Most of the time, 94% of their capacity is wasted. Using our recently introduced CDN (content delivery network) technology, they can build an elastic CDN so they can switch nodes on or off, and assign the unused nodes to other tasks, such as file encoding for VOD or for dynamic ad insertion. MARKET DEMAND The bad news: TV channel operators have not shown much interest yet in green OTT. The good news: they do want cost efficiency. Since resource optimisation reduces costs, that creates an indirect demand for green OTT. Telecom Argentina, Post Luxembourg and Netplus have all adopted our technology – reducing the environmental footprint of their service platforms, while also increasing their efficiency. We will not stop people from watching TV. But we are proud to help our customers deploy the technology that makes this habit that much greener.

Instead of having to store the same content in different formats, just-in-time packaging means TV service providers only need to store content once, reducing their storage requirements threefold while supporting Google Android, Apple iPhone and Microsoft, for example. Our technology uses the same servers for streaming and storing content, halving the number of physical rack units needed. Our shared workflow approach allows TV service providers to use the same video data for live, start-over, catch-up and cloud DVR (digital video recorder). This significantly reduces the use of storage and network bandwidth requirements. Carefully implemented resource sharing allows a single server to be used for multiple functions instead of being dedicated to a single role. Video traffic PRIVATE CLOUD FOSTERS GOOD BEHAVIOUR
