FAQs

It's recommended to perform a comprehensive audit monthly, with daily checks on critical transmission parameters and real-time monitoring systems in place.

The audit typically covers signal strength, video and audio quality, encoding efficiency, multiplexing integrity, satellite uplink performance, and terrestrial transmission systems.

The audit should be led by broadcast engineers and transmission specialists, with support from quality control technicians and network operations center staff.

By ensuring optimal signal quality and minimizing transmission errors, the audit helps deliver a seamless viewing experience, reducing complaints and improving overall audience satisfaction.

Automation systems play a crucial role in continuous monitoring of transmission parameters, providing real-time alerts for deviations from set quality thresholds and logging performance data for analysis during audits.
