Introduction :

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 and 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 :

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)
HDCAM Compressed (220 Mbps) & Uncompressed (1.5Gbps) HDTV over IP
- Collaboration with UW Research Channel Consortium
