Realizing Advanced Video Optimized Wireless Networks






Realizing Advanced Video Optimized Wireless Networks

The IEEE ICC 2012 Workshop on Realizing Advanced Video Optimized Wireless Networks will be held at ICC 2012 in Ottawa, Canada on June 15.

Video content delivery over wireless networks is expected to grow exponentially in the coming years. It is driven by applications including streaming TV content to mobile devices, internet video, video on demand, personal video streaming, video sharing applications (from mobile to mobile), video conferencing, live video broadcasting (cloud to mobile as well as mobile to cloud), video Twitter, and video blogging. In fact, a recent study (Cisco Visual Networking Index) predicts that the mobile video traffic will exceed 50% of the total mobile data traffic in 2011 and will be approximately two-thirds of the global mobile data traffic by 2015.  Improvements in video compression and wireless spectral efficiency will not be sufficient to accommodate this potential demand.  Although there has been a wealth of research in the area of joint source-channel coding and wireless video optimization over the past decades, few of these techniques have yet to be realized in practical networks.

This workshop will bring together academic and industrial researchers to focus on the intersection between theory and practice of bringing advanced video optimization techniques to wireless networks in practical ways. There will be  multi-disciplinary set of presentations, panel discussions, and keynote presentations to cover the range of topics related to realizing advanced video optimized wireless networks.

Wireless Video Optimizations and Error Resiliency

  • Multi-user distortion aware resource allocation and cross-layer optimizations.
  • Joint source-channel coding using perceptual video quality distortion metrics.
  • Practical ways to realize wireless video optimizations in a layer-aware fashion, including information exchange methods between layers.
  • Machine learning techniques for dynamically optimizing wireless video.

Adaptive video streaming and transport for wireless networks

  • Dynamic Adaptive HTTP Streaming (DASH) and other HTTP-based adaptive streaming optimizations for wireless networks.
  • Scalable compression techniques for practical traffic shaping in the network.
  • Energy efficient wireless media transmission.
  • Analog and digital network coding for wireless media.

Novel wireless network architectures optimized for video distribution

  • Practical cooperative network architectures (hierarchical, heterogeneous, peer-to-peer, hybrid broadband/broadcast) specifically for optimized video delivery.
  • Relaying for wireless media transmission.
  • Distributed caching techniques for popular video content.


Workshop Program

8:30am-10:00am Session Video Quality of Experience
8:30am Introduction to Workshop Prof. Robert W. Heath Jr, UT Austin
8:35am Keynote 1: Designing for Exponential Growth in Mobile Video Traffic:  Applications, Codecs, Networks, and Quality Prof. Jerry Gibson, UCSBDesigning for exponential growth in mobile video traffic is daunting enough, but the real challenge comes from supporting the heterogeneous mix of video applications driving this growth.  To meet this challenge, we discuss (1) new requirements on video codecs, (2) the need to acquire and use all information in the network, and (3) the development of new “Assessed Quality” measures that go beyond network QoS and perceptual QoE to individual users.  The impact of the “long tail” nature of mobile video applications is examined in detail, and the critical role of the intelligent, autonomous access point/base station is presented.

10:30am-12:40am Session Cross-layer Video Optimizations
10:30am Keynote 2: Network resource use and Video QoE – a coding perspective Muriel Médard, MIT 

Meeting QoE requirements has challenged CDNs and wireless delivery, prompting the deployment of more wireless infrastructure and more deployment of data centers. In this talk, we present three instances to illustrate how we can make use of network coding to reduce the use of network resources while maintaining QoE. In the first instance, we consider the use of network coded TCP to reduce the use of the network by avoiding needless retransmissions. In the second example, we use network coding in order to call upon scarce network resources, such as cellular telephony networks, only when an interruption in video is imminent over the Wifi system. Finally, we show how to use network coding in data centers to reduce storage and server requirements while maintaining probability of blocking requirements.
