clock

The clock command is used to manage SMPTE ST 2110 synchronization on the encoder. 

Note

SMPTE ST 2110 must be licensed on the encoder, and the encoder personality set to ST 2110.

Synopsis

clock set parameter=value [parameter=value...]
clock get [config, stats, all]

Actions


ActionDescription

set

Configures ST 2110 synchronization settings. A series of one or more parameter=value pairs can be specified at once. See Parameters below.

get

Displays ST 2110 synchronization information. 

Parameters

ParameterDefaultDescription/Values
mode

ts_conv

Specifies the timestamp mode for the ST 2110 synchronization:

  • ts_conv: Timestamps for the video/audio/ancillary data are directly taken from the sources and streamed exactly as is. Recommended to use in a good environment where PTP is working well and all devices are synchronized properly.
  • restamp: Timestamps are generated locally by the Makito X for the video/audio/ancillary data. Recommended to use in situations (such as a demo) where the networking is not ideal, the system cannot achieve PTP lock, but you still want to be able to use ST 2110.

Examples

# clock get

Returns ST 2110 synchronization information, such as (on a system with no ST 2110 streams coming in):

Configuration:
  Mode          : TS_CONV
Status:
  Clock ID      : 00:00:00:00:00:00:00:00
  STC           : 0x18adddccd
Lock          : UNLOCKED
# clock get

Returns ST 2110 synchronization information, such as (on a system with ST 2110 streams coming in):

Configuration:
  Mode          : TS_CONV
Status:
  Clock ID      : 8C:A5:A1:FF:FE:00:08:19
  STC           : 0x098f95d52
  Lock          : LOCKED
  Precision     : 50 nanosecs
