Sample interview questions: How do you ensure the synchronization of audio and video signals during live broadcasts?
Sample answer:
- Audio/Video Delay Compensation: Introduce a delay to either the audio or video signal to match the transmission delays or processing times between the two signals.
- Reference Signals: Embed timecodes or synchronization pulses into both the audio and video signals to establish a common reference for aligning them.
- Synchronizing Generators: Use a central reference generator or master clock to provide a timing signal for all audio and video equipment, ensuring that they are operating in sync.
- Lip-Sync Correction: Monitor the audio and video signals during transmission and adjust the audio delay manually or automatically to compensate for any discrepancies in lip movements.
