Abstract
Disclosed are a coded video data processing method and apparatus which consider a random access, and a coded video data generating method and apparatus which consider a random access. 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.
Claims10
A coded video data processing method comprising:
- obtaining coding information and metadata information from a bitstream;
- decoding decodable-leading pictures according to the coding information;
- and
- performing video-processing on the decodable-leading pictures based on 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 obtained with coding information of a first-decoded picture of the scene from among the decodable-leading pictures.
A video data processing apparatus comprising:
- a bitstream obtainer for obtaining coding information and metadata information from a bitstream;
- a video decoder for decoding decodable-leading pictures according to the coding information;
- and
- a video processor for performing video-processing on the decodable-leading pictures based on 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 obtained with coding information of a first-decoded picture of the scene from among the decodable-leading pictures.
