MPEG stands for:
- (a)Moving Picture Experts Guide
- (b)Moving Picture Experts Group
- (c)Moving Picture Effect Group
- (d)Moving Picture Effect Guide
Correct — B, Moving Picture Experts Group. MPEG is the working group formed in 1988, under the ISO/IEC joint technical committee, to set international standards for compressing and transmitting digital audio and video — its name is literally 'Moving Picture Experts Group,' after the kind of content (moving pictures = video) it standardises.
- (a)Moving Picture Experts Guide — Swaps 'Group' for 'Guide' — MPEG is a standards-setting working GROUP of experts, not a published guide.
- (c)Moving Picture Effect Group — Swaps 'Experts' for 'Effect' — the body is a group of technical experts, not a visual-effects group.
- (d)Moving Picture Effect Guide — Combines both wrong substitutions — neither 'Effect' nor 'Guide' is part of the real name.
MPEG (Moving Picture Experts Group) is the ISO/IEC working group that develops international standards for compressing and packaging digital audio and video so it can be stored and transmitted efficiently. Its standards — MPEG-1 (which includes the MP3 audio format), MPEG-2 (used in DVDs and digital television broadcast), and MPEG-4 (used in most modern streaming/video files) — underpin nearly all digital video and audio in everyday use.
Acronym questions like this test the exact wording — students who correctly recall 'MPEG = video standards body' but guess at the precise words ('Group' vs 'Guide', 'Experts' vs 'Effect') get tripped up. Anchor the acronym to its real identity: a GROUP of EXPERTS, not a guide or an effects team.
- MPEG = Moving Picture Experts Group, formed in 1988 under the ISO/IEC joint technical committee.
- Co-founded and chaired (1988-2020) by the Italian engineer Leonardo Chiariglione.
- MPEG standards include MPEG-1 (contains the MP3 audio format), MPEG-2 (DVD/digital TV), and MPEG-4 (modern streaming/video).
- MPEG standardises compression so video/audio files are smaller and can be transmitted and stored efficiently.
Only 'Moving Picture Experts Group' is the real name of the ISO/IEC standards body.
- Confusing MPEG (video/audio compression) with JPEG (still-image compression) — both are ISO/IEC groups but standardise different media
- Guessing 'Guide' or 'Effect' instead of the real words 'Group' and 'Experts'
MPPSC/UPSC-adjacent IT-awareness questions test exact-wording acronym expansions (MPEG, JPEG, W3C, HTTP) — memorise the literal words, not just the general meaning.

Which of the following MPEG standards includes the widely used MP3 audio format?
- (a)MPEG-1
- (b)MPEG-4
- (c)MPEG-7
- (d)MPEG-21
Answer(a) MPEG-1 — its audio layer III (MP3) became the dominant compressed-audio format.

JPEG, the standard for compressing still images, is developed by a body analogous to MPEG. JPEG stands for:
- (a)Joint Photographic Experts Group
- (b)Joint Photographic Effects Group
- (c)Joint Picture Experts Guide
- (d)Joint Photographic Experts Guide
Answer(a) Joint Photographic Experts Group — the sister ISO/IEC group to MPEG, for still images.
