11 Channel Pack Validation
Testing on a representative K2Edge system, against a representative schedule, with representative
content, is the only way to determine if a channel pack is ready for on-air usage. Only go on air with a
validated channel pack!
Channel Packs should be validated against a test schedule. The playback statistics tool can be helpful
with this. While the test schedule is played out on a test server - using hardware, content and a schedule
closely similar to the ones used for actual playout - the statistics tool is displayed as an on-screen overlay
and shows real-time playback information:
• the current and peak amount of active players per type
• the amount of active templates and objects
• the amount of upload bandwidth from system RAM to the graphics card RAM, which is
“expensive”
• the durations of the update and render phases in milliseconds and the sum of both durations
(total)

Please note that these statistics can also be viewed using the statistics option in Channel Composer Try-
out Mode. However, Channel Composer cannot measure the durations of the update and render phases.
This can only be done on a test playout server. Monitoring playback statistics during playout of a test
schedule gives a good sense of the actual system load templates generate when run.
