Define multimedia data. What are the two techniques used to overcome jitter?

What will be an ideal response?

We use the term multimedia to refer to data that contains audio or video, and may include
text. The phrase real-time multimedia refers to multimedia data that must be reproduced at exactly
the same rate that it was captured. To overcome jitter and achieve smooth playback of real-time data,
two chief techniques are employed:
? Timestamps. A sender provides a timestamp for each piece of data. A receiver uses the
timestamps to handle out-of order packets and to display the data in the correct time
sequence.
? Jitter Buffer. To accommodate jitter (i.e., small variances in delay), a receiver buffers data and
delays playback.
