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)

Delivery specifications differ because cinema projection uses a Digital Cinema Package (DCP) designed for theater projectors, while online streaming relies on compressed formats optimized for internet playback. In cinema, the standard is DCP packaging with JPEG 2000 image encoding, a fixed 24 frames per second, and a choice of 2K or 4K resolution, paired with multichannel audio such as 5.1 or 7.1 and separate subtitle metadata. For streaming, content is encoded with highly compressed codecs like H.264 or H.265 (HEVC), often with variable frame rates and adaptable bitrates to match available bandwidth, and delivered in containers such as MP4 or WebM, with multiple audio tracks and subtitles that can be embedded or streamed separately. This combination reflects the different playback environments and bandwidth considerations between cinema and online platforms. The other options mix up formats and capabilities in ways that don’t align with real-world delivery: DCP packaging isn’t used for streaming, and cinema isn’t limited to MP4; color or monochrome and uncompressed video aren’t typical distinguishing factors for these delivery paths.
