## Question

Calculate the total memory (frame buffer size) required to store a 10 minute video in a SVGA system with 24 bit true color (without compression), with a 60 fps refresh rate.

## Short answer

Assuming SVGA 800×600, one frame = 800×600×24 bits = 1.37 MB. For 10 minutes at 60 fps, total frames = 36,000, requiring approximately 5.18×10^10 bytes (48.3 GB) of storage.

## Answer

Assume SVGA resolution = 800 × 600 pixels.

```text
Bits per pixel      = 24 (true colour)
Bits per frame      = 800 × 600 × 24   = 11,520,000 bits
Bytes per frame     = 11,520,000 / 8   = 1,440,000 B ≈ 1.37 MB
Time                = 10 min × 60      = 600 s
Frames              = 60 fps × 600 s   = 36,000
Total memory        = 1,440,000 × 36,000
                    = 51,840,000,000 bytes
                    ≈ 48.28 GB (÷ 2³⁰)   (≈ 51.84 GB in decimal)
```

**Answer: about 5.18 × 10¹⁰ bytes ≈ 48.3 GB** (one frame buffer = 1.37 MB).

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. What resolution is assumed for SVGA?
   A. 640 x 480
   B. 1024 x 768
   C. 1280 x 1024
   D. 800 x 600
   Answer: D. The answer assumes SVGA = 800 x 600. (Key point: SVGA resolution)

2. What is one frame's size at 24-bit true colour?
   A. 1,440,000 bytes (about 1.37 MB)
   B. 480,000 bytes
   C. 11,520,000 bytes
   D. 144,000 bytes
   Answer: A. 800 x 600 x 24 = 11,520,000 bits = 1,440,000 bytes. (Key point: Bytes per frame)

3. How many frames are in 10 minutes at 60 fps?
   A. 3,600
   B. 36,000
   C. 6,000
   D. 600
   Answer: B. 60 x 600 s = 36,000. (Key point: Number of frames)

4. What is the total memory required?
   A. About 5.18 x 10^8 bytes
   B. About 1.44 MB
   C. About 51.84 x 10^9 bytes (about 48.3 GB)
   D. About 518 GB
   Answer: C. 1,440,000 x 36,000 = 51,840,000,000 bytes. (Key point: Total)
