Minimum frame size = 160 bits
What is bit rate?
- Whether in audio or video, bitrate refers to the amount of information present, according to director and filmmaker Mike Leonard.
- It is frequently expressed in terms of information per second. Unlike other measures of video quality like frame rate, resolution, or video format, bitrate is a unique metric.
- Bit Rate = Total number of Bits per Baud x Baud Rate
Bit rate = 4 kbps
One-way propagation delay = 20 ms
Efficiency = Transmission time of packet/(Transmission time of packet + 2 * Propagation delay)
- 0.5 = x/(x + 2 * 20 * 10^-3)
- x = 20 * 10^-3
- x = 40 * 10^-3
Minimum frame size / Bit rate = 40 * 10^-3
Therefore, Minimum frame size = 40 * 10^-3 * 4 * 10^3 = 160 bits
