Dynamic adjustment of video frame sampling rate

A method, comprising:

• determining a frame rate of a first plurality of video frames in a first video signal received from a first module by a second module, the first module operating according to a first clock and the second module operating according to a second clock independent of the first clock;
• adjusting, by the second module, a sampling rate according to the determined frame rate of the first plurality of video frames;
• sampling, by the second module, the first plurality of video frames at the adjusted sampling rate;
• generating, by the second module, a second video signal comprising a second plurality of video frames based on the sampled first plurality of video frames;
• and
• transmitting, by the second module, the second video signal wirelessly to a third module;
• wherein the determining of the frame rate of the first plurality of video frames comprises omitting an abnormal or irregular frame of the first plurality of video frames in calculating the frame rate of the first plurality of video frames using time values recorded in timestamps associated with the first plurality of video frames.

An apparatus, comprising:

• a first module configured to output a first video signal comprising a first plurality of video frames;
• and
• a second module configured to perform operations comprising:
• receiving the first video signal from the first module;
• determining a frame rate of the first plurality of video frames;
• adjusting a sampling rate according to the determined frame rate of the first plurality of video frames;
• sampling the first plurality of video frames at the adjusted sampling rate;
• and
• generating a second video signal comprising a second plurality of video frames based on the sampled first plurality of video frames;
• wherein the first module operates according to a first clock and the second module operates according to a second clock independent of the first clock;
• and
• wherein, in determining the frame rate of the first plurality of video frames, the second module is further configured to omit an abnormal or irregular frame of the first plurality of video frames in calculating the frame rate of the first plurality of video frames using time values recorded in timestamps associated with the first plurality of video frames.

• and
• generating a second video signal comprising a second plurality of video frames based on the sampled first plurality of video frames;
• wherein, in generating the second video signal comprising the second plurality of video frames based on the sampled first plurality of video frames, the second module is configured to perform operations comprising:
• modifying a time value recorded in a respective timestamp associated with a first video frame of the first plurality of video frames;
• and
• generating a second video frame of the second plurality of video frames based on the first video frame of the first plurality of video frames,
• wherein a time value recorded in a respective timestamp associated with the second video frame is different from the time value recorded in the respective timestamp associated with the first video frame.
