NCODING OF THE
SMPTE 334M
PACKETS ON THE
DOWNCONVERTED OUTPUTS
Multicam 8.03, and higher versions, can manage the encoding of the SMPTE334M
present on the HD output on the SD downconverted output as well.
This parameter can be activated on the shift-F2 screen.
For the downconverted output, one SMPTE 334M packet is encoded per line
starting from the second line after the line specified for the switching line. In
other words, the maximum number of packet per field is as follows:
• 8 packets per field in 525i (lines 12-19 and 275-282)
• 15 packets per field in 625i (lines 8-22 and 321-335)
