close captioning or SDP teletext. If detected, this is appropriately de-modulated
into EIA-608 close caption or OP-47 subtitling packets and inserted as ancillary
data packets into an ancillary data track on the imported clip.
• Line 19-PAL and 14-NTSC (default, can be overridden via registry) is examined
for the presence of VITC. If detected, this is appropriately de-modulated into
SMPTE 12M compliant time-code values which is inserted as time-code values
into the time-code track on the imported clip.
• The following applies to the Pinnacle emulation K2 FTP import:
• All supported FTP commands, with the exception of those mentioned below,
respond as they do for a conventional K2 FTP session. For instance, commands
such as renames and deletes operate on K2 clips, directory listings reveal K2
clips and bins, and so on.
• Navigation (cd) to K2 bins is allowed. By default, the default K2 bin is projected
as the FTP root.
• The MKD/XMKD command does not create a K2 bin for the argument specified,
but merely retains the argument as the name of the K2 clip to be created based
on following STOR commands.
• The CWD/XCWD command does not allow navigation to a K2 bin. If the
Pinnacle clip name used in a previous MKD command is used as an argument to
CWD, the K2 FTP server does not internally navigate to that “bin”, but rather
merely returns a success status.
• The STOR command only honors ft, std, or header as arguments, or filenames
with a .mxf extension. When the K2 FTP server receives data for the std file it
creates a K2 clip with the name issued by a previous MKD/XMKD command.
Connecting RS-422
You can control the K2 system with remote control devices and software developed
for the K2 system that use industry-standard serial protocols: AMP, BVW, and
VDCP.
K2 Media Clients have been manufactured with two types of RS-422 configurations,
as follows:
• Two dual-port adapters.
• One adapter with an external 8-port interface. On the external interface, ports 1–4
are active.
Refer to the following for more information about RS-422 and protocol control:
• Appendix A, Remote control protocols
• K2 Media Client User Guide to configure the K2 system for remote control.
