Which digital compression format is widely used around the world?

• A. MPEG-1
• B. MPEG-2
• C. MPEG-3
• D. JPEG

Answer: (B)

MPEG-2 is a widely used digital compression format because it is specifically designed for the transmission and storage of high-quality video and is commonly utilized in various applications such as digital television broadcasts, DVDs, and streaming services. Its efficiency in compressing video data while maintaining quality allows for effective delivery of video content over different types of networks and mediums.

MPEG-2 supports higher resolutions and provides better error correction compared to earlier formats, making it suitable for both standard-definition and high-definition video. This versatility has led to its adoption in various industries, securing its position as a global standard for video compression.

In contrast, while MPEG-1 was an earlier standard focused on lower video qualities and data rates, and JPEG is primarily used for still image compression rather than video, MPEG-3 was not widely adopted and is less relevant in practical applications. The focus of MPEG-2 on video streaming and storage directly aligns with current technologies and industry standards.
