Bit-rate selection for wireless networks

Mobile and tablets are used in wireless networks. A property of wireless networks is that bandwidth fluctuate a lot more than in fixed networks. Wireless signals goes through air and is obstructed by other signals, buildings, geographical features an so on. The result is that, even in very modern wireless networks, users will experience considerable bandwidth variations. Adaptive HTTP (used Smooth, HLS and MPEG DASH) is a technology that is well suited to handle these changes in network capacity, as the client can choose a bit-rate that is appropriate for its bandwidth. It is up to the client to choose bit-rates, and we develop algorithms that are a part of our SDK and makes this choice. Our algorithms minimizes the chance of the client to get buffer under-runs and do not change quality-layer too often (as this is proven to disturb viewing experience).

Note: We let the native player choose bit-rates when the SDK is delivered as as a part of an app.
