Welcome to APAN HDTV WG. This HDTV WG is formed to provide APAN members with an opportunity to discuss the latest development around the network-based delivery of HD (high-definition) video technology. Aiming to provide immersive experience to end users with HD quality video, lots of efforts are now taking place to enable HD video contents over high-speed research networks. By connecting these efforts together, we are going to achieve the following goals.
Objectives:
  - Collaborate on the development of HDTV delivery technology over regional & international R&D networks  (Initial focus will be on the HDV over IP project)
  - Construct the HDTV-enabled advanced media distribution infrastructure by deploying the developed HDTV toolkit
  - Share and promote the distribution of HDTV contents over the media distribution infrastructure
  - Assist application and user communities to enable HDTV-supported collaboration

Milestones/Actions:
  1. HDV over IP Project (MPEG-2 Compressed MP@HL 19.2Mbps by MPEG-2 TS over RTP/UDP/IP)
     - Using HDV Camcoders from companies like JVC
     - Software vs. Hardware-assisted (low-cost) decoders
     - Multicast-based HDV distribution infrastructure (linking senders and receivers)
  2. HDCAM Compressed (220 Mbps) & Uncompressed (1.5Gbps) HDTV over IP
     - Collaboration with UW Research Channel Consortium

Meetings:
2008.1 Hawaii USA
2007.8 Xi'An China
2007.1 Manila Philippines
2006.7 Singapore
2006.1 Tokyo
2005.7 Taipei
