HDCAM HD Format
The HDCAM HD format is compatible with SMPTE 274M/292M and uses compression to achieve a recorded bit rate of about 143 Mb/s for active picture.  16:9 High Definition Television Aspect Ratio is equivalent to 1.77:1 Film Aspect Ratio.  A superb downconversion to Standard Definition Television through an external digital downconverter or via an SRW5000 or SRW5500 series VTR with HDCAM playback (including L/R positioning of center cut, or retention of 16:9 orientation via letterbox or squeezed pixel) can result in improved Standard Definition resolution in both luma and weighted chromanance channels.  The common practice for Cinematographers is to frame for widescreen (in High Definition, this is 16:9), and protect for 4:3.

See also the section on JH HDCAM Players.  HDCAM  normal record and playback frame rates are 25/29.97/30 (device depending), but  in the later versions of Sony /20 models, include 23.98/24 CineAlta frame recording and playback (again, device depending).  HDCAM CineAlta (for Cinema Alternative) refers to the additional  HDCAM frame rates of 23.98/24 (device depending). 23.98/24 Frame 1080 HD Recording is part of the ATSC HDTV Delivery Standards, and, without 3:2 Pull Down, represents a savings of up to 25% in storage costs over 29.97/30 frame rates.  In addition, many display and digital processing devices now support 23.98/24PsF input, making HDCAM CineAlta VTRs well suited for production facilities wanting to deliver lower cost high quality 8-Bit HD-SDI component digital content for television, cable, industrial, corporate, educational, and point of sale applications. 

HDCAM SR refers to a different tape format with a different tape stock, data rates, and tape speeds, and is not supported in current HDCAM VTRs or Camcorders.   The exception is the new combination SRW-5500 Multi-Format HDCAM-SR/HDCAM VTR (see the HDCAM-SR Section of this web site and call VTP for additional information).
