|
Which statement correctly describes frame encoding?
|
|
It generates the electrical, optical, or wireless signals that represent the binary numbers of the frame.
|
|
|
It uses the characteristic of one wave to modify another wave.
|
|
|
It transmits data signals along with a clock signal which occurs at evenly spaced time durations.
|
|
|
It converts bits into a predefined code in order to provide a predictable pattern to help distinguish data bits from control bits.

Explanation:
Detailed explanation-1: -In video compression, encoding the differences between frames rather than each full frame. Interframe coding often provides substantial compression because in many motion sequences, only a small percentage of the pixels are actually different from one frame to another.
Detailed explanation-2: -to reduce the number of collisions on the media. to distinguish data bits from control bits. to provide better media error correction. to identify where the frame starts and ends. to increase the media throughput. More items •03-Mar-2020
