What is the primary purpose of transporting video and audio as a multiplexed stream over a network?

• A. To encrypt content.
• B. To carry video and audio as a multiplexed stream over a network.
• C. To store video in local cache.
• D. To convert to subtitles.

Answer: (B)

The main idea is to deliver video and audio together in a single, synchronized data flow. By multiplexing, the separate video and audio streams are packed into one stream (often with timing information) so the receiver can decode them in the correct order and keep audio and video in sync during playback. This makes transmission over a network efficient and reliable, supports real-time playback, and allows adding other data like subtitles within the same stream. Encrypting content or storing locally are separate concerns and aren’t the purpose of multiplexed transport, and converting to subtitles isn’t about delivering the whole media stream.
