IMAGE ENCODING/DECODING METHOD AND DEVICE BASED ON HYBRID NAL UNIT TYPE, AND RECORDING MEDIUM FOR STORING BITSTREAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18371232 titled 'IMAGE ENCODING/DECODING METHOD AND DEVICE BASED ON HYBRID NAL UNIT TYPE, AND RECORDING MEDIUM FOR STORING BITSTREAM

Simplified Explanation

The image encoding/decoding method described in the abstract involves obtaining NAL unit type information from a bitstream, determining the NAL unit type of one or more slices in the current picture, and decoding the current picture based on the determined NAL unit type, particularly focusing on RASL and IRAP pictures.

  • NAL unit type information is obtained from a bitstream.
  • NAL unit type of slices in the current picture is determined based on the obtained information.
  • Decoding of the current picture is done based on the determined NAL unit type, with a focus on RASL and IRAP pictures.

Original Abstract Submitted

An image encoding/decoding method and apparatus are provided. The image decoding method includes obtaining, from a bitstream, network abstraction layer (NAL) unit type information of at least one NAL unit including coded image data, determining at least one NAL unit type of one or more slices in the current picture based on the obtained NAL unit type information, and decoding the current picture based on the determined NAL unit type. The current picture is determined to be a random access skipped leading (RASL) picture, based on the determined NAL unit type including a RASL picture NAL unit type (RASL_NUT). When an intra random access point (IRAP) picture associated with the RASL picture is a first picture in decoding order, the RASL picture is decoded, based on the RASL picture including one or more slices having a random access decodable leading (RADL) picture NAL unit type (RADL_NUT).
