Abstract

With the increase in network speeds for both wired and wireless networks, video streaming has become a reality. But different networks are characterized by different network speeds and latency. Also different kinds of devices are used with different networks. These devices range from Desktop/Laptop computers with very high resolution and very high processing power to Mobile Phones with small displays, low processing power and limited battery life. A single common non-scalable video feed for all these different profiles of networks and devices is impractical as streaming a high quality feed may not be possible over GPRS type of networks and streaming a low quality feed may not be visually acceptable to a user with high network bandwidth and high resolution display. To overcome this problem multiple video feeds are used, each catering to a different profile of users. Content creation process becomes complex as multiple files have to be created usually using a different codec and file format. Deployment involves replication of hardware and software infrastructure and associated overhead of maintenance, hence increased cost.
