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 (SMPTE D-12); also generally called DV-100 in reference to its bit-rate of
100 Mbps.
• D-9 HD, an extension of the Digital S format. (Digital S is also 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 1.5Gb/sec.). There are no
camcorder (in which the recorder is built into the camera) 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.
A Comparison of Common High Definition and Standard
Definition Formats
The table below shows the relative data rates of some commonly used high
definition formats.
