Which device syncs a tape-based source to house sync to ensure all cameras and recorders capture frames simultaneously?

• A. Time-Base Corrector
• B. Frame Sync
• C. Genlock
• D. Timecode Reader

Answer: (A)

Syncing a tape-based source to house sync hinges on correcting irregular timing introduced by tape playback so every device can share a stable frame timing. A Time-Base Corrector reads the video from tape, buffers it, and retimes the signal to a constant clock. That clean, properly timed video can then be synchronized to the house reference, allowing all cameras and recorders in the system to capture frames together. Frame timing on tape is often jagged, and the TBC smooths that out before the signal is referenced to the common sync. While other devices manage frame timing in different ways—frame sync aligning frame boundaries, genlock distributing a shared timing reference to multiple devices, and timecode readers providing metadata—none addresses the tape’s own timing jitter as directly as a Time-Base Corrector.
