How is bandwidth calculated from frame size and frames per second?

To determine bandwidth in terms of frame size and frame rate, the correct approach involves understanding how these elements interact. Bandwidth indicates the amount of data that is transmitted in a given time frame, and is typically expressed in kilobytes per second (KB/s).

When calculating bandwidth, you multiply the frame size by the number of frames per second. The reasoning behind this is that if you have a certain size of each frame, and you are transmitting multiple frames every second, the total amount of data transmitted is simply the size of one frame multiplied by the total number of frames sent in that second.

For instance, if each frame is 1 KB and you are sending 30 frames per second, the total bandwidth required would be 1 KB/frame * 30 frames/second, which equals 30 KB/s. This method gives a clear result reflecting how much bandwidth is needed to accommodate the video stream without any loss or lag.

In contrast, adding or subtracting the frames per second and frame size does not provide a meaningful representation of the data transmission rate, as those operations do not reflect the relationship between data volume and time.
