Chapter 13 : Digital Video Data Sizing

Data Rate
- is the rate where information being transferred
- per unit time

Calculating file size of an uncompressed digital file

Raw video data size

= frame size (width X height) * frame rate (fps) * colour depth (in bytes) * time (in seconds)

8 bits = 1 byte

1 kilo(bit/byte) = 1,024 (bits/bytes)

1 Mega(bit/byte) = 1,048,576 (bits/bytes)

1 Giga(bit/byte) = 1,073,741,824 (bits/bytes) Factors to consider when selecting graphics to be used in a multimedia project: - purpose  - cost  - quality

Chapter 12 : Broadcast Video Standards

Broadcast Video Standard

•NTSC (National Television Standards Committee)

  - 525 lines/60Hz

  - This standard is used primarily in North America, Taiwan, South, Korea, Japan.

  - 30 fps

•PAL (Phase Alternate Line)

  - 625 lines/50Hz

  - This standard is used primarily in Europe, Asia, and Southern Africa.

  - 25 fps

•SECAM (Systeme Electronique Couleur Avec Memoire)

  - 625 lines/50Hz

  - This standard is used primarily in France, parts of Middle East, and Russia.

  - 25 fps

Aspect Ratio

• The aspect ratio of a frame describes the ratio of its width to its height in the dimensions of a frame

• For example, the frame aspect ratio of NTSC or PAL video is 4:3, whereas DVD, HDTV, and motion-picture         frame sizes use the more elongated aspect ratio of 16:9
