Compressed High Definition Tape Formats
Because of the high data rate generated by high definition video cameras, most HD
formats compress the image data to fit on tape.
 DVCPRO HD; also generally referred to as DV-100 (in reference to its bit-rate of
100 Mbps).
 D-9 HD, an extension of the Digital S format. (Digital S is designated SMPTE D9.)
 D-5 HD, an extension of the D-5 format.
 HDCAM and HDCAM-SR (an extension of the HDCAM format).
Uncompressed High Definition Tape Formats
High definition requires extremely high data rates (around 1.4 Gbps). There are no
camcorder formats currently available for recording uncompressed HD video. High-
capacity, general-purpose digital tape formats like D-6 can be used in combination
with camera heads and digital telecine machines capable of outputting uncompressed
RGB and component HD video data. High-speed disk arrays can also be used to record
uncompressed HD video.

1 HDV uses MPEG-2 compression, which has varying compression ratios. MPEG compression ratios are often
expressed as a bit rate.
