Which organization is dedicated to standardizing digital multimedia?

• A. MPEG
• B. MTC
• C. NAT sound
• D. MOS

Answer: (A)

The concept here is identifying who creates and standardizes the formats used for digital multimedia so different devices and software can read and play the same files. That role is filled by the Moving Picture Experts Group, a standards body within ISO/IEC that develops widely adopted formats like MPEG-1, MPEG-2, MPEG-4, and MP3. These standards specify how audio and video data are encoded, compressed, and decoded, enabling interoperability across cameras, players, and streaming services. The other terms aren’t organizations dedicated to standardizing multimedia formats; they refer to specific production terms or technologies (for example, MIDI Time Code, natural sound, or a no-sound workflow), not a global standardization body.
