The coded video data processing method includes obtaining a bitstream of coded video data, obtaining metadata information used for video-processing of pictures having a decoding order after a random access point picture in the bitstream, and performing video-processing on decoded video data among the pictures having the decoding order after the random access point picture, based on the metadata information. ## Claims ### Claim 1 A coded video data generating method comprising: coding video data; generating metadata information, wherein the metadata information comprises information about a scene comprising one or more pictures; and generating a bitstream of the coded video data, the bitstream comprising the metadata information or metadata identification information corresponding to the metadata information, wherein the metadata information for the scene is generated with coded video data of a first-decoded picture of the scene from among decodable-leading pictures. ### Claim 2 (depends on 1) The coded video data generating method of claim 1, wherein the generating of the bitstream comprises generating the bitstream by inserting the metadata identification information into a predetermined location in the bitstream. ### Claim 3 (depends on 2) The coded video data generating method of claim 2, further comprising transmitting the bitstream comprising the metadata identification information, and a metadata information database comprising the generated metadata information, via different channels. ### Claim 4 (depends on 1) The coded video data generating method of claim 1, wherein the generating of the bitstream comprises generating the bitstream by inserting the metadata information into a location of a random access point picture and a location of a scene cut of a scene comprising one or more pictures having a decoding order after the random access point picture. ### Claim 5 (depends on 4) The coded video data generating method of claim 4, wherein the generating of the bitstream comprises, if the random access point picture and decodable leading pictures belong to a same scene, generating the bitstream by inserting metadata information of the scene to which the random access point picture and the decodable leading pictures belong, into a location of a first decodable leading picture in a display order. ### Claim 6 (depends on 4) The coded video data generating method of claim 4, wherein the generating of the bitstream comprises, if the random access point picture and decodable leading pictures belong to different scenes, generating the bitstream by inserting metadata information of the scene to which the random access point picture belongs, into a location of the random access point picture, and inserting metadata information of the scene to which the decodable leading pictures belong, into a location of a first decodable leading picture in a display order. ### Claim 7 (depends on 4) The coded video data generating method of claim 4, wherein the location of the scene cut corresponds to a location of a first picture in a display order among pictures belonging to each scene. ### Claim 8 A coded video data generating apparatus comprising: a video coder configured to code video data and generate metadata information; and a bitstream generator configured to generate a bitstream of the coded video data, the bitstream comprising the metadata information or metadata identification information corresponding to the metadata information, wherein the metadata information comprises information about a scene comprising one or more pictures, and wherein the metadata information for the scene is generated with coded video data of a first-decoded picture of the scene from among decodable-leading pictures. ### Claim 9 (depends on 8) The coded video data generating apparatus of claim 8, wherein the bitstream generator is further configured to generate the bitstream by inserting the metadata information into a location of a random access point picture and a location of a scene cut of a scene comprising one or more pictures having a decoding order after the random access point picture.
