Quality of experience for mobile video users.Throughout the world, more and more people are choosing a mobile device as their platform of choice for watching video content. Some people use their mobile phones to catch the latest sports highlights, while others watch television shows on the train during their commutes. Some viewers use the WiFi in the local coffee shop to connect to Hulu on their netbooks, and others watch full-length movies on their iPods.
Regardless of the type of device, content viewed, or network used for access, each person has some basic expectations about the viewing experience. The level of expectation varies among viewers, depending on factors such as the amount of money spent for the service, type of content being requested, and type of device being used for viewing. It is the job of service providers to match the level of quality to their users’ expectations.
