OmniTek OTR 1001 User Guide, v3.1 J-1
J : Event Handling
The OTR 1001 offers a range of responses to specific conditions or transitions within the video
stream that is being analysed.
One response is to generate a list of these conditions and transitions as they occur, known as an
‘Event Log’. The OTR 1001 offers both a listing of such events as they happen (a ‘Live’ log) and
the opportunity to save sequences of these events for further analysis and/or recording in an
XML file.
The OTR 1001 can also respond to events by generating an alarm and/or transmitting an SNMP
alert. These functions all work independently.
In addition, separate logs can be created of Momentary & Short-Term Loudness values (see
Section J.2) and of captions embedded in the text and associated settings (see Section J.3).
Both log entries and SNMP alerts can be marked with the machine time and/or VITC, ATC or
LTC timecodes where present.
J.1 Event Logs
Overview
The entries in an Event Log are all triggered by ‘events’. These events may correspond to a
marker such as timecode or a closed caption being detected within the input video stream but
they are most commonly associated with the detection of an error condition or the transition of
the video stream into or out of a particular state.
The conditions under which an error is reported are set through the Video Config and Audio
Config pages of the Configuration window. These pages list the parameters of the video that
your OTR system is able to monitor, and allows you to specify for each parameter:
1. The conditions under which the OTR should report an error
2. The level of error that should be reported – from ‘OK’ through ‘Warning’ to ‘Error’
3.
Whether the error should be logged in the ‘Event Log’ and/or cause an Alarm to be
generated and/or generate an SNMP alert.
The following sections describe the different ways in which the OTR 1001 may respond to
events. They also describe the options that are available for recording sections of the Live log on
disk as ‘Session logs’ and for analysing these logs.
Event Log Display
The Event Log is one of the analyses offered under the STATUS category.
The Event Log automatically offers a ‘Live’ log, listing events as they happen on the currently
selected input video stream. It can also display the results of one or more ‘logging sessions’,
which may be started and stopped either manually or at specific points in the video being
analysed. These logging sessions are started and stopped independently and may run
concurrently. The resulting ‘Session logs’ can also be saved as XML files and analysed to show
the frequency of the different types of event.
