Motivation
The increase of mobile computing has led to a
change from the traditional computer-centered to
a future human-centered information access mode.

Problem Definition
Most video streaming contents were designed with
desktop computers and high-speed network
connections

• Server-based adaptation
• Creating different versions
• Client-based adaptation
• Intelligent client
• Intermediate-based adaptation
• Independent of servers and clients, ex) proxy
• Combinations of the above approaches
