Supporting wireless video Growth and Trends


Video is increasingly becoming one of the most pervasive technologies in terms of everyday usage, both for entertainment and in the enterprise environments. Mobile video is responsible for a majority of the growth seen in mobile broadband data volume. 

This white paper presents the expected growth of mobile video based on current trends and user behaviors, describes the various types of video based on content type or delivery strategy, and details the various challenges and solutions to deliver mobile video over a wireless end-to-end network. A multipronged approach to address the various challenges, unique to mobile video, is presented through optimization techniques in the radio and core networks 



(HTTP Adaptive Streaming, etc.), support of multiple network architectures (HET-NETs, LTE broadcast, content delivery networks), support of client optimizations and through enhanced codecs (HEVC). Metrics for quantifying and attributes that contribute to improved video QoE are described in detail. Recommendations on bit rates for various codecs and screen sizes, and recommendations for video application developers to support the scalable growth of video in mobile networks are made after examining unique aspects specific to mobile video delivery.
