The most immediate obstacle in multimedia communication is bandwidth. Uncompressed digital video, for example, requires hundreds of megabits per second—far beyond the capacity of most networks. Halsall emphasizes that compression standards are not optional but essential. Techniques like JPEG for still images and MPEG (MPEG-1, MPEG-2, MPEG-4) for video exploit spatial and temporal redundancy. Spatial redundancy reduces data within a single frame (e.g., using Discrete Cosine Transform), while temporal redundancy encodes only the differences between consecutive frames. Audio compression, using perceptual coding (e.g., MP3, AAC), discards sounds inaudible to the human ear. These standards, discussed at length in Halsall’s text, form the backbone of all modern multimedia systems, from videoconferencing (H.261/H.263) to streaming services. : Techniques like MP3 and AAC for high-fidelity sound
