HDTV WG Milestones HDTV WG Milestones (Revised (Revised DRAFT 1.26)DRAFT 1.26)

1. HDTV Delivery Toolkits Collaborations1. MPEG-2 Compressed (MP@HL,19.2Mbps)

• Focus on collaborative reviews and comparisons• Sender: Stored vs. Live (JVC/Sony HDV camcoders & encoder card);

Receiver: S/W vs. H/W-assisted decoders

2. HDCAM Compressed (HD 270Mbps)• Build reference H/W platform & co-develop toolkit (RC-based or others)

3. Uncompressed HDTV (sub Gbps ~ 1.5 Gbps)• Build reference H/W platform & co-develop toolkit (Ultra Grid-based or

others)

• Multicast-based HDTV distribution infrastructure (linking servers and clients)

• HDTV contents sharing WWW Portal
