Abstract
Provided are a method and a device for decoding a Picture Order Count (POC), and a method and a device for coding a POC, and electronic equipment. The method for decoding the POC includes that: parameters for Most Significant Bit (MSB) and Least Significant Bit (LSB) used in an alignment operation on the POC are acquired; an MSB value and an LSB value of a POC value of a current picture are determined according to the parameters for MSB and LSB; and the POC value of the current picture is calculated according to the MSB value and the LSB value. By means of the technical solution, the problems in the related art that the accuracy in decoding and outputting a multilayer video bitstream cannot be ensured and an extra overhead of network resources is increased in multilayer video coding and decoding processes are solved.
