Wireless Video Adaptation

Definition:Wireless streaming requires video coding to be robust to channel impairments and adaptable to the network and diverse scenarios; wireless video adaptation deals with rate adaptation and robustness adaptation.

With the rapid growth of wireless communications and the advance of video coding techniques, wireless video streaming is expected to be widely deployed in the near future. However, due to the characteristics of wireless networks such as high error rate, limited bandwidth, time-varying channel conditions, limited battery power of wireless devices and the diversity of wireless access networks and devices, wireless video streaming faces many challenges. In particular, from the coding point of view, wireless streaming requires video coding to be robust to channel impairments and adaptable to the network and diverse scenarios. Traditional media coding standards such as MPEG-2 and MPEG-4 are not suitable any more since they are targeted to a particular range of bit rates and...
