Efficient low bit rate video compression technique for mobile applications

With the entry of 3G services, video based applications like live video streaming, gaming applications, video telephony are going to be in great demand. The data speed is limited in Mobile applications as the bandwidth available is a limited resource. The demand for video streaming is expected to grow in multi folds in future and speed is a critical issue in video streaming. Techniques that reduce the video bit rate are the best way to have a smooth video streaming for a given bandwidth. The mobile equipment screen displays are usually small in size, this size can hence be exploited to have a certain level of compromise with video resolution and by deploying good video compression techniques, the bit rate can be reduced to suit the mobile based applications. Improved video compression is an example of better spectral efficiency (getting the most out of limited bandwidth), which is what makes 3G cellular technology more advanced than its predecessors.
