Additional sources possible
Composite, S-video, component (I/P modes)
XGA (30 Hz, 24 bit compressed 32:1)
Capability in 2Q01
Max Data BW: 20 Mbps
Additional sources possible
Native MPEG2 HDTV
XGA (30 Hz, 24 bit compressed 27:1)

9. Summary Compression factor depends on image content
March 2000
Summary
Compression factor depends on image content
High frequency content
Bandwidth driver is computer graphics
Games with high quality graphics running at 60 fps
Resolutions will move toward HDTV (1280x720)
Minimum Data BW needed for XGA
38 Mbps
Assumes a 30:1 compression ratio
Current standard bandwidth goals are too low and too late
IEEE a is the only standard effort RF close at 32 Mbps data rate
Requires 35:1 compression of XGA for acceptable image quality
Will be available at end of 2001 (earliest)
