DCP（数字电影包）DCP
交付 · Delivery
DCP（Digital Cinema Package，数字电影包）是影院放映的封装与编码标准——MXF 装素材、JPEG 2000 编码。
- 不是普通 MP4：给影院的片子走 DCP，家用交付的格式逻辑在这里不适用。
- 组成：MXF 封装 + JPEG 2000 编码，配放映服务器的目录结构。
- 和交付地图的关系：它占「交付」一环里最特殊的位置——先问「给谁看、在哪放」，进影院就是 DCP。
DCP (Digital Cinema Package) is the packaging and codec standard of cinema projection — MXF carries the material, JPEG 2000 encodes it.
- Not an ordinary MP4: films headed to cinemas travel as DCP; home-delivery logic does not apply here.
- What it is made of: MXF packaging + JPEG 2000 encoding, arranged for the cinema server.
- Its place on the delivery map: the most special stop on the delivery leg — first ask "for whom, on what screen"; a cinema means DCP.
