Supported Reference Formats

Depending on the input reference format you use, you will only be able to operate the switcher in certain formats. References to 1080p 59.94Hz (A) and 1080p 50Hz (A) refer to 1080p Level A only.

Notes

  • * It is not recommended that you operate the switcher in these video formats when you are using a composite sync (480i or 576i) reference signal. SMPTE® recommends using a tri level sync reference signal for high-definition video.
  • ** The 1080p 50Hz Level B and 1080p 59.94Hz Level B video formats are only accepted by the MultiProcessor Input and 12G MultiProcessor Input boards where they are converted to level A automatically.
  • *** Only the MultiProcessor Input and 12G MultiProcessor Input boards can process UHDTV1 UHD-2SI video signals. Only the 12G MultiProcessor Input can process UHDTV1 UHD-2SI at 12Gb/s.
Important: Format conversion of Level B to A causes a 2-line delay in the MultiProcessor Input board for that input. All Level B inputs must be advanced by 2-lines before they come into the switcher.

The switcher allows you to use any interlaced video format to operate the switcher in any format of the same frequency; however, the use of 480i or 576i (Composite Sync) reference signals for High Definition (720p, 1080i, or 1080p) video modes is not recommended. Using a composite sync reference signal for High Definition video modes results in excessive jitter on the video output of the switcher, falling outside the range specified by SMPTE-292M. This may result in downstream equipment being unable to properly receive these signals.

The use of composite sync reference formats is recommended for Standard Definition video modes only, and provides stable outputs with jitter performance in compliance with SMPTE-259M specifications.
