And, here are the JVC ProHD competitive features:

JVC GY-HD250U 1/3-inch 3CCD

Native acquisition 1280x720p60 (No tricks needed)

ProHD recording of full ATSC 1280x720p60 resolution

Compressed MPEG-2 GOP transport stream = 20Mbps (19.7)

HD-SDI out

Interchangeable lens

SD Pool feed input

Panasonic has recently announced their new AVC-Intra CODEC which does provide for full ATSC bandwidth mode, but at a compressed bitrate of 100Mbps. A 50Mbps mode will be available, but this is still high for HD ENG implementations within existing ENG work flows. AVC-Intra is scheduled for first deliveries in the summer of 2007. Based on prior experience with new HD compression formats, it will take some time before industry partners are ready to fully support the brand new format in workstations, laptop editors, servers and networks.

Native Acquisition & Pixels per Second presented To the Home HDTV

Earlier in this Report (page 10), we discussed “the total number of effective maximum pixels per second” being presented to the home viewer through the home HDTV, and the effect of the Kell/Interlace factor in substantially decreasing the total perceived resolution for interlaced video while barely affecting progressive video. It seems obvious that such pixels per second presentation may be limited by the following:
