ITPEC FE Morning April 2023 — Question 24 of 80

Video Bandwidth Calculation — compute minimum uncompressed video throughput.

Given: 800 × 600 pixels, 24-bit color, 30 fps, no compression.

  • •Frame size = 800 × 600 × 24 = 11,520,000 bits
  • •Bandwidth = 11,520,000 × 30 = 345,600,000 bps ≈ 350 Mbps

Why not others:
- (a) 350 kbps — off by a factor of 1,000
- (b) 3.5 Mbps — off by a factor of 100
- (c) 35 Mbps — off by a factor of 10

Key rule: bandwidth = width × height × bits_per_pixel × fps (no compression = raw size).
