Io Express Installation and Operation Manual — Setup Window
SDI Output
Io Express has one SDI output so the SDI output will be Single Link.
Analog Output
Analog format choices in the Analog Output pull-down menu vary with selected file format. For
example, “Com Y/C” is only available when an SD format is in use.
Analog Output Options Supported by Io Express cards include:
Com Y/C
Component (SMPTE/EBU N10)
Component (Beta)
Timecode Input
Select the type of timecode used by the source video machine — RS-422, Embedded SDI
(RP188) or choose to input an External LTC timecode source input via the Io Express RS-422 port.
Note:
SMPTE RP 188 defines a standard for the transmission of timecode and control code in
the ancillary data space of a digital television data stream. Timecode information is
transmitted in the ancillary data space as defined in ANSI/SMPTE 291M. Multiple codes can
be transmitted within a single digital video data stream. Other time information, such as
real time clock, DTTR tape timer information, and other user-defined information, may also
be carried in the ancillary timecode packet instead of timecode. The actual information
transmitted through the interface is identified by the coding of a distributed binary bit.
Equipment manufacturers can use the meta data for different purposes. After configuring
Machina Capture Options, select the Play options by clicking on the toggle arrows on either
side of the Capture Options title header.
Play Options
Primary Format, and Output Type
settings are all the same for playback mode as those
described previously. Refer to the Capture Options section.
Audio Sync
Because there is no conversion in Io Express, Audio synch is always to the Primary source.
Audio Sample Rate
In Io Express the audio sample rate is always 48 KHz.
