On Factors Affecting the Usage and Adoption of a Nation-wide TV Streaming Service

Download to read offline

Using nine months of access logs comprising 1.9
Billion sessions to BBC iPlayer, we survey the UK ISP ecosystem to understand the factors affecting adoption and usage of a high bandwidth TV streaming application across different providers. We find evidence that connection speeds are important and that external events can have a huge impact for live TV usage. Then, through a temporal analysis of the access logs, we demonstrate that data usage caps imposed by mobile ISPs significantly affect usage patterns, and look for solutions. We show that product bundle discounts with a related fixed-line ISP, a strategy already employed by some mobile providers, can better support user needs and capture a bigger share of accesses. We observe that users regularly split their sessions between mobile and fixed-line connections, suggesting a straightforward strategy for offloading by speculatively pre-fetching content from a fixed-line ISP before access on mobile devices.

  3. 3. Users have a lot of choice in Video Access Devices Pricing models Operators • Different networks 3G/4G and WiFi often both together • Different Pricing (unlimited and limited data plans) • Different devices (phones, tablets, PCs, Game Consoles, TVs, etc.) We need to study the whole ecosystem to understand user choices
