ACKETS SUPPORTED
Up to now, SMPTE 334M data packets carried on the chrominance (C) data stream
within the SMPTE 292M signal are not decoded (HD).
From Multicam 8.03, all DIDs mentioned in the SMPTE 334M standards are
supported:
• 61 О 62
• 40 О 5F
• C0 Î DF
Those DIDs are saved and restored on the output channels on their original lines.
The other DIDs are not saved.
The maximum number of bytes saved per field (frame for 720p) is 2014. One saved
SMPTE 334M packet is composed of user data word (UDW) plus 7 configuration
bytes. It has to be taken into account to compute the number of bytes saved.
Please refer to the SMPTE RP 291-2006 standard for the assignment of DIDs to
specific applications.

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)
