Method and apparatus for video coding

An apparatus, comprising:

• processing circuitry configured to:
• decode a first portion of video data to obtain first data of a first reconstructed picture, the first data including a first data set that corresponds to a first information category and a second data set that corresponds to a second information category, the first data set and the second data set being mutually exclusive;
• determine whether to store both of the first data set and the second data set of the first reconstructed picture in a reference data memory;
• in response to a determination by the processing circuitry to store both of the first data set and the second data set in the reference data memory, store the first data set and the second data set in the reference data memory, and
• in response to a determination by the processing circuitry not to store both of the first data set and the second data set in the reference data memory, store the first data set in the reference data memory without storing the second data set in the reference data memory;
• and
• decode a second portion of the video data to obtain second data of a second reconstructed picture based on reference data stored in the reference data memory.

A non-transitory computer-readable medium storing instructions which when executed by a computer for video decoding causes the computer to perform:

• decoding a first portion of video data to obtain first data of a first reconstructed picture, the first data including a first data set that corresponds to a first information category and a second data set that corresponds to a second information category, the first data set and the second data set being mutually exclusive;
• determining whether to store both of the first data set and the second data set of the first reconstructed picture in a reference data memory;
• in response to determining to store both of the first data set and the second data set in the reference data memory, storing the first data set and the second data set in the reference data memory, and
• in response to determining not to store both of the first data set and the second data set in the reference data memory, storing the first data set in the reference data memory without storing the second data set in the reference data memory;
• and
• decoding a second portion of the video data to obtain second data of a second reconstructed picture based on reference data stored in the reference data memory.
