Warning
Changing the default parameters listed below will risk violation of conformance with the CableLabs standard.
There are many interpretations of the CableLabs standard and compliance depending on which device is performing playout or other operations on a transport stream. We invite you to reach out for specific integrations or with any questions on what parameters might need to be modified for your specific use cases.
