In the example here, event-based presets are set to detect when an SD feed without Dolby E 5.1 is received. In this example,
this event would invoke a failover preset that (a) provides up-convert to 720p5994 and (b) develops a 5.1-channel upmix to
substitute for the normal HD 5.1-channel content decoded and applied to the card Dolby AC-3 encoder.

When the normal 720p5994 feed with Dolby E 5.1 is again received, a second event-based presets load returns to the card to
normal processing (turn off scaler and revert to using Dolby E 5.1 for the decoder source and AC-3 PCM source).

Events-Based Preset
Loading
set to Enabled turns
on controls, allowing defined
conditions to be checked.

Conditions (A), (B), and (C) for Event 1 are set to
recognize (when all true), an overall condition
indicative of loss of normal HD feed. In this example:

• Video changing to SD format.

• Loss of Dolby E 5.1 at decoder input and instead

audio consisting of PCM.

• Muting of audio on embedded channels that

expectedly would contain 4 channels of
multi-channel audio.

When all Event 1 conditions
are true, the selected preset is
invoked. (In this example,
Preset 8 would invoke an
SD-to-720p HD conversion, as
well as upmixing a stereo PCM
pair to 5.1 content.)

Note: • Checked conditions are triggered upon start of event. Any event-based setup must be done in advance of the

triggering event in order for event to be detected.

• Loss of true conditions does not disengage an event-based triggering. A new set of true conditions must be

defined and then occur to transition from one event-based trigger to another.

• Time required to engage an event-based trigger depends upon complexity of the called preset. (For example,

a preset that invokes a scaler format change will take longer to engage than a preset involving only an audio
routing change.)

• Make certain all definable event conditions that the card might be expected to “see” are defined in any of the

Event 1 thru Event 64 rows. This makes certain that the card will always have a defined “go-to” preset if a
particular event occurs. For example, if the card is expected to “see” a 720p5994 / Dolby E5.1+2 stream or as
an alternate, a 525i5994 / PCM stream, make certain both of these conditions are defined (with your desired
go-to presets) in any two of the Event 1 thru Event 64 condition definition rows.

Conditions (A), (B), and (C) for Event 2 are set to recognize (when all
true), an overall condition indicative that the normal HD feed is again
available. In this example:

• Video changing to 720p5994 format.

• Dolby E 5.1 again detected by the card Dolby decoder.

When all Event 2 conditions are true, the
selected preset is invoked. (In this example,
Preset 1 would invoke scaler bypass, as
well as routing decoded Dolby audio to the
card audio bus.)
