Managing the media downloads to the cache
The SSP-3801 card features onboard storage space that allows you to store and preload
media content locally so that it can be retrieved and broadcast smoothly and quickly. You
can define how the card manages the media cache and what action it should take if the
server times out and the media cannot be accessed.
To configure how the media cache is managed:
1 Select Channel Configuration > Media Cache. The Media Cache page opens.
Fig. 2-4: Media Cache page
2 In the Channel Media section, define when the indicated pre-broadcast alarms are
triggered (in HH:MM format).
• Missing Media time window: type the amount of time before broadcast to trigger
the Missing Media alarm if the media file cannot be found.
• Inaccessible Media time window: type the amount of time before broadcast to
trigger the Inaccessible Media alarm if the media file was found, but cannot be
downloaded to the SSP-3801’s storage space.
3 In the Transfer Speed Alarm section, define
• Minimal Download Speed: type the minimum acceptable download speed (from 1
to 100MB/s) for the media. An alarm is triggered if the download speed falls below
the specified threshold.
• Speed Test Period: type the number of seconds (from 1 to 120) defining the length
of the test period used to verify the actual download speed. The download speeds
are tested throughout the specified duration and are averaged. The resulting value
is compared to the Minimal Download Speed threshold to verify its performance.
4 In the Max segments per download field, type the maximum number of blocks (up to
10) you can download per server at a time.
IMPORTANT:
When the SSP-3801 card is registered with GV STRATUS Playout, then GV
STRATUS Playout overwrites any Channel Configuration changes made
through the card’s web interface any time it updates the card with its own
changes.
