Mobile networks have constraints such as energy consumption, limited radio spectrum, radio propagation characteristics, and interference. It is not possible to deliver video streaming data without adaptation at client or server or network. This chapter aims at describing the challenges in delivering video in mobile network. It also presents various adaptation technologies for mobile video streaming, and identifies a few potential research problems to improve mobile video steaming service. First, an overview of a mobile broadband architecture is provided. Next, the chapter talks about video streaming protocols. HyperText Transfer Protocol (HTTP) and Real-Time Streaming Protocol (RTSP) are two popular protocols used for video streaming. The chapter illustrates how video optimizer (VO) and content delivery network (CDN)-based delivery techniques are applied in mobile networks to deliver video streaming in an effective manner while maintaining good quality of experience (QoE).
