Disclosed is an apparatus and method of processing input and output in a multi-kernel system. A method of processing input and output in a multi-kernel system according to the present disclosure includes: setting a shared memory between a first kernel on a main processor and a lightweight kernel on a parallel processor; setting a data transmission and reception channel between the first kernel on the main processor and the lightweight kernel on the parallel processor using the shared memory; providing, on the basis of the data transmission and reception channel, an input/output task that occurs in the lightweight kernel to the first kernel on the main processor; processing, by the first kernel on the main processor, an operation corresponding to the input/output task; and providing a result of the processing to the lightweight kernel.

Scheduling threads in a system with many cores includes generating a thread map where a connection relationship between a plurality of threads is represented by a frequency of inter-process communication (IPC) between threads, generating a core map where a connection relationship between a plurality of cores is represented by a hop between cores, and respectively allocating the plurality of threads to the plurality of cores defined by the core map, based on a thread allocation policy defining a mapping rule between the thread map and the core map.

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.
