What is the bit rate for transmitting uncompressed \(800 \times 600\) pixel colour frames with 8 bits/pixel at 40 frames/second ?
Answer: C
The bit rate is 153.6 Mbps. Each frame has \(800 \times 600 = 480000\) pixels at 8 bits per pixel, giving 3,840,000 bits per frame. At 40 frames per second:
\[ 3\,840\,000 \times 40 \]
\[ = 153\,600\,000 \text{ bits/s} \]
That is 153.6 Mbps. The figure 15.36 Mbps is ten times too small, 1536 Mbps is ten times too large, and 2.4 Mbps does not follow from the data.
