The ProHD Report

JVC’s ProHD came out of the HDV MPEG-2 consortium (Canon, JVC, Sharp, Sony) but, of the four, only JVC elected to concentrate on full bandwidth native acquisition, recording and transport by choosing the 1280x720p60 ATSC format. Thus ProHD is uniquely qualified for cost effective HD ENG applications.

The HDV-related CODECs by Canon and Sony only covers 1080i60, with 4:2:0 sub- sampling, and reduced bandwidth:

Canon HDV 1/3-inch 3CCD (models XH-A1/G1 & XL H1)

Native imager acquisition 1440x1080i60 plus pixel shift/offset

HDV recording of 1440x1080i60 max resolution

Compressed MPEG-2 GOP transport stream = 25Mbps+

Only XL H1 & XH G1 have HD-SDI out

Only XL H1 has interchangeable lens

Sony HDV 1/3-inch 3CCD (models HVR-Z1/A1)

Native imager acquisition 960x1080i60 plus pixel shift/offset

HDV recording of 1440x1080i60 max resolution

Compressed MPEG-2 GOP transport stream = 25Mbps+

NO HD-SDI out

All models have fixed lenses

Sony XDCAM HD 1/2-inch 3CCD (models PDW-F330/F350)

Native imager acquisition 1440x1080i60

Optical disc (PD) recording of 1440x1080i60 max resolution

Compressed MPEG-2 GOP bitrate = Hi=35/Mid=25/Lo=18Mbps (Hi-35 and Lo-18 are VBR recording)

HD-SDI out only on F350

Interchangeable lenses

Panasonic never joined the HDV consortium, choosing to offer a competitive model to the HDV camcorders with the DVCPRO-HD capable HVX-200, and, just announced before the NAB-2007, the HPX500:

Panasonic HVX200 1/3-inch 3CCD

Native imager acquisition 960x540p60 plus 2-dimensional pixel shift/offset

DVCPRO-HD recording of 1280x1080i60 max resolution

DVCPRO-HD recording of 960x720p60 max resolution

Compressed DVCPRO-HD bitrate = 120Mbps (approx gross)

NO HD-SDI out

Fixed lens
