摘要
An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate a multiplexed signal at a fixed frame-rate in response to a video input signal. The multiplexed signal comprises one of (i) a pre-defined packet which corresponds to a new frame rate detected on the video input signal when in a first mode (ii) repeated video frames at the fixed frame-rate when in a second mode and (iii) augmented digitally repeated frames at the fixed-rate when in a third mode. The second circuit may be configured to generate a video output signal in response to decoding (i) the multiplexed signal at the new frame rate defined by the pre-defined packet when in the first mode or (ii) the repeated video frames on the multiplexed signal at the fixed frame-rate when in the second mode.
