Abstract: A signal receiving apparatus is provided. A time de-interleaver performs time de-interleaving on multiple interleaved video frames to generate a time de-interleaving result, and generates a counting request upon identifying a starting point of an interleaved video frame under verification. A signal processing circuit performs signal processing having an average delay on the time de-interleaving result to generate a signal processing result.

A verification circuit generates a counting result according to the counting request and the output request, and determines whether the TTO satisfies a predetermined condition according to the counting result and the average delay.
