ITPEC IP April 2025 — Question 25 of 100
MPEG — the MPEG standards include compression for moving pictures together with associated audio.
MPEG formats are designed for multimedia streams and use temporal as well as spatial compression techniques for video, while also specifying audio coding. This makes MPEG appropriate when both video and sound must be compressed.
Answer (d)
Why not others:
- (a) BMP is primarily a still-image bitmap format and is often uncompressed
- (b) GIF is an indexed still-image format that can contain simple animation but not general synchronized audio
- (c) JPEG compresses individual still images and does not itself encode audio
Key rule: JPEG targets still pictures; MPEG targets time-based multimedia such as compressed video and audio.
