Video on demand gives VCR-like playback from a video server over a network. Interactive video and audio let users control content through branching stories, playlists and games. ## Answer Multimedia combines text, audio, images, video and interactivity, which makes it central to modern entertainment media. #### Interactive TV (ITV) Interactive television lets viewers act on what they watch instead of only receiving a one-way broadcast. A return channel (cable, internet or mobile) carries the viewer's choices. - Voting and polls in shows, quizzes, and choosing camera angles in sport. - On-screen programme guides (EPG), shopping and ordering from adverts, and extra information about a programme. - Examples: smart TV apps, set-top boxes with a remote, IPTV. #### Video on demand (VoD) VoD lets users choose a video and watch it at any time, with VCR-like functions (play, pause, rewind, fast forward). - Needs a video server that stores compressed (MPEG) video, a high-bandwidth network and a set-top box or app at the user's end. - Types: true VoD (any time, immediate), near VoD (starts at fixed intervals), pay-per-view. - Examples: Netflix, YouTube, Amazon Prime Video, and IPTV and streaming apps offered by Nepali providers. - Issues: server capacity, bandwidth, quality of service, digital rights management and billing. #### Interactive video and audio The user controls the content flow rather than simply watching or listening. - Interactive video: branching storylines, clickable hotspots, training videos with quizzes, 360-degree videos. - Interactive audio: music players with playlists, interactive music mixing, audio books with chapters, voice response systems, games with dynamic sound. - Used in e-learning, advertisements, museums and games. ```text Video server --> Network --> Set-top box/app --> TV ^ | +------ user request ------+ ``` **Benefits:** personalised, on-demand and engaging entertainment. **Requirements:** compression, high bandwidth and low delay. ## Check yourself The answer's key points as multiple-choice questions, with the correct option and why. 1. What makes television 'interactive' rather than a one-way broadcast? A. A larger screen B. A return channel (cable, internet or mobile) carries the viewer's choices C. Higher video resolution D. Use of MPEG compression Answer: B. ITV lets viewers act on what they watch, using a return channel to carry their choices. (Key point: Interactive TV return channel) 2. Which VoD type starts the video at fixed intervals instead of immediately? A. True VoD B. Pay-per-view C. Interactive VoD D. Near VoD Answer: D. Near VoD starts at fixed intervals; true VoD is any time and immediate. (Key point: Types of VoD) 3. What does a VoD system need? A. A video server storing compressed video, a high-bandwidth network and a set-top box or app B. Only a broadcast antenna C. An uncompressed video store and a low-bandwidth link D. Only a return channel without a server Answer: A. VoD uses a server with compressed (MPEG) video, high bandwidth and a user-end set-top box or app. (Key point: VoD requirements) 4. Which is an example of interactive video? A. A live news broadcast with no controls B. A single fixed-order audio track C. Branching storylines and clickable hotspots D. A recorded lecture played once Answer: C. In interactive video the user controls the flow, e.g. branching storylines, hotspots, quizzes and 360-degree video.
