                               Abstract
       • This submission presents technical requirements that 
         should be met in order to support reliable transmission 
         of high quality audio and video contents over WLAN. 
         These requirements, which are derived from use 
         cases that are well recognized in a CE context,  include 
         reliable delivery of broadcast and multicast frames, 
         time synchronization, and hooks for DRM support.

                    Trends of CE Devices
      • More and more CE devices become to support wireless connectivity.
      • Network-enabled and application-specific
        – Simplified or even no network layers
        – Network functions only required by specific applications
      • Carrying broad ranges of contents
        – Various video and audio types of different qualities
        – Casting many different constraints for QoS:
          bandwidth, reliability, latency, etc.
      • Growing computing power but still limited
        – Not general-purpose machines
        – Equipped with only minimal computing power
