What are typical delivery specifications differences for cinema projection versus online streaming?

• A. Cinema requires DCP packaging (JPEG 2000, 24fps, 2K/4K, 5.1/7.1 audio); streaming uses compressed formats like H.264/H.265 with variable frame rate, bitrate, and different metadata; include audio codecs and subtitles accordingly.
• B. Streaming uses DCP packaging; cinema uses MP4
• C. Cinema uses only black-and-white; streaming uses color.
• D. Streaming requires uncompressed video; cinema uses MPEG-2.

Answer: (A)

Delivering to a cinema relies on a Digital Cinema Package (DCP) designed for exact, consistent playback on theater projectors. In a DCP, video is encoded with JPEG 2000, typically at 24 frames per second, and available in 2K or 4K resolutions, with high-quality multi-channel audio such as 5.1 or 7.1. Subtitles and metadata are also packaged in formats that cinema servers and projectors can read reliably, ensuring uniform color, timing, and audio across venues.

Online streaming, on the other hand, is optimized for varying bandwidth and a wide range of devices. Video is compressed into formats like H.264 or H.265 and delivered in containers such as MP4 or similar, with the ability to adapt the bitrate and even frame rate to network conditions. Audio is provided in common codecs (such as AAC), and subtitles are supplied in web-friendly formats like WebVTT or SRT. These choices prioritize efficient compression, broad compatibility, and adaptability for online viewing.

So the combination of a DCP with JPEG 2000 at fixed 24fps and 2K/4K plus 5.1/7.1 audio for cinema, versus compressed H.264/H.265 streams with flexible bitrate and metadata for streaming, is what distinguishes the typical delivery specifications between the two environments.
