Closed Caption
Insertion Display
Row Displayed when Inserted CC Enabled is set. Sets the position on the
screen where the text defined in the Closed Caption Text field will
appear in the decoded video. Can be set from 1 through 15, where 1
indicates the top of the screen and 15 indicates the bottom of the
screen (default is 15), when Inserted CC is enabled.
Closed Caption
Insertion Update
Rate Sets the rate at which the closed captioning field is updated (default
= Medium) when you select Inserted CC Enabled (see above).
• Slow – Inserted closed caption field updated every 10 seconds.
• Medium – Inserted closed caption field updated every 5 seconds.
• Fast – Inserted closed captioning field updated every second.
Detected Format Shows the detected Video Format (see Figure 1) and Aspect Ratio
that is actually connected.
KLV KLV metadata is supported on the serial port(s) and on the network
port. If you are using the serial ports on a device with multiple
channels, only the first two channels support KLV metadata in the
stream: Channel 1 uses COM2 and Channel 2 uses COM1. If you are
receiving KLV or CoT into the encoder over the network, only one
metadata feed can come in this way, although a second KLV or CoT
feed can come in over the serial port. For more information about
this topic see Key Length Value (KLV) Metadata.
• Disabled – KLV metadata is not embedded in the stream.
• ESD to LDS – Available on any interface that supports (CC in
line 21) closed captions. These include Composite NTSC,
Component 480i, and SD-SDI 480i.
• Serial LDS Passthrough – LDS metadata is provided via the serial
port and embedded into the transport stream.
• SDI LDS Passthrough – LDS packets will be received over the
Vertical Ancillary Data Space (VANC) as per MISB RP 0605.2.
• Network LDS Passthrough – LDS metadata is provided via the
specified IP network port and embedded into the transport
stream.
• Serial CoT to LDS – CoT (Cursor on Target) data is provided via
the serial port and is converted to LDS and embedded into the
transport stream.
• Network CoT to LDS – CoT data is provided via an IP network
port and is converted to LDS and embedded into the transport
stream.
KLV PTS Used if KLV data source is Serial, SDI, or Network LDS
Passthrough. Select the Presentation Time Stamp method:
• Capture Time – Uses the time of data reception to generate the
metadata stream PTS. Defaults = System Time.
• LDS Time – Uses the timestamp extracted from the LDS packets
to generate the metadata stream PTS.
KLV Multicast
Source Used with Network LDS Passthrough or Network CoT to LDS.
