Panasonic is not in the group at this time, however, JVC is owned by Matsushita, the parent company of Panasonic. It seems like they are hedging their bets.

Hey Frank, no he meant JVC as they were the company that brought out the single chip HD camera, but I agree, kill Betacam & for you guys over in the states sakes, kill NTSC forever. We Aussies are lucky we're backwards?? we've been enjoying Pal since '66. Pete C

<<<-- Originally posted by Chris Hurd : It's not data rate, Don... FireWire supports 400 megabits per second; HD is 100 megabits per second.>>>

Panasonic's compressed HD is 100 mbps. True uncompressed
1080i and 720p HD I believe are both close to or over 1 gigabit per second.

The 100mbps Panny variety is actually compressed
at something over 6:1 and is 8 bit. Using the varicam and a panasonic
D5 ( AJ-HD3700B) VTR you can even record 10bit uncompressed.
Sony's HDCAM is also compressed at 4:1 if my memory is right.

According to this page and Michael Robin (guru) from broadcast engineering
the "nominal" bit rate for uncompressed 10 bit 4:2:2 HD is 1.485 Gbps.

http://2001newsarchive.broadcastengineering.com/ar/broadcasting_hdtv_data_multiplexing_4/

According to fiberoptics-info:

SMPTE 259M Level C NTSC (4:2:2) 4 x 3 13.5 MHz = 270 Mb/s

SMPTE 292M 16 x 9 Hi Def 74.25 MHz = 1.485 Gb/s
