Abstract
Provided are an apparatus and method for generating digital cinema content and an apparatus and method for playing digital cinema content. The method of playing digital cinema content using a digital cinema package (DCP) including frame data having a first resolution and length information about frame data having a second resolution lower than the first resolution, and a key delivery message (KDM) includes obtaining a material exchange format (MXF) file and a decryption key by parsing the DCP and the KDM, extracting an encrypted triplet from the MXF file, extracting the length information about the second-resolution frame data using the encrypted triplet and the decryption key, decrypting an amount of data required to decrypt the second-resolution frame data in the first-resolution frame data using the length information about the second-resolution frame data, and decoding the decrypted second-resolution frame data.
