m16307

• 
  File Format
  
  • 
    P2P traffic is increasing but no SDO feeling responsible. (IETF is considering PPSP as an exploration activity)
    
  • 
    De-facto standard such as BitTorrent does not support P2P (video) streaming.
    
  • 
    MPEG-21 DID provides support for P2P systems e.g., fragment identifier can be used to refer parts of content which can be used to integrate one file at the receiver side.
    
  • 
    Propose to start working towards a file format explicitly support P2P streaming and associated metadata
    
• 
  Cross-Layer Optimizations
  
  • 
    Preferred approached to achieve cross-layer design is jointly optimizing parameters at each layers.
    
  • 
    ENTHRONE cross-layer model describes the relationship between QoS metrics at different levels and Cross-Laer adaptation decision-taking engine solves optimization problem.
    
  • 
    Propose to improve metadata to describe cross-layer model to close interoperability gaps
    
• 
  Context and Content aware Networks
  
  • 
    context describes the environment and metadata describe content
    
  • 
    mismatch between context and content may require adaptation
    
  • 
    Not only media aware clients but also media aware network are becoming more and more important
    
  • 
    Propose to work on generic interface between the coding layer and delivery layer
    

m16327

• 
  AVC and SVC standards assumed media aware network element deciding discard or forwarding packets.
  
• 
  MANE has two roles such as identification of each packet for extraction and context aware adaptation
  

m16353

• 
  Broadcasting and mobile convergence  supporting of generic mechanism to identify streams when hand-over between networks is happened
  
• 
  QoE  more metadata to support better QoE
  

m16362

• 
  Use cases and environment
  
  • 
    one-to-one over IP is predominant
    
  • 
    “punch-in” is needed to for live stream
    
  • 
    RTP-UDP and MPEG-2 TS over UDP both contain a “blast and hope” assumption while TCP aware congestion
    
  • 
    Supporting content protection is necessary
    
  • 
    Metadata is becoming increasingly important
    

m16392

• 
  HTTP streaming with MP4 files requires new mechanism for live & adaptive service scenario
