Mobile TV

• Equalizing perceived-quality for multiple concurrent TV channels: We consider a mobile TV system that broadcasts several video sequences at the same time, while these video sequences have heterogeneous characteristics/complexities and require diverse bit rates to achieve the same perceived-quality. Our goal is to determine the best streaming bit rate for each TV channel such that all TV channels achieve a uniform perceived-quality that is less than or equal to a given target quality chosen by network operators.
  • We then show that by tolerating a small quality variation (or quality degradation), we can increase the energy saving (or battery life).
  • The same approach can be applied to an Internet on-demand video server. This is to make sure each user receives good, but not too good, quality so that the streaming server load (or even the bandwidth consumption) is reduced.
