Neural video coding

An electronic device comprising:

• a processor;
• and
• a memory coupled to the processor and comprising instructions stored thereon which, when executed by the processor, cause the device to perform acts comprising:
• obtaining estimated motion information of a target frame in a video and reference feature information and a reference reconstructed frame of a reference frame for the target frame;
• determining, using a context extraction model, context information for the target frame based on the estimated motion information, the reference reconstructed frame, and the reference feature information;
• and
• generating, in a conversion between the target frame and a bitstream of the video, a target reconstructed frame of the target frame using a frame coding model and based on at least the context information.

A computer program product being tangibly stored in a computer storage medium and comprising computer executable instructions that, when executed by a device, cause the device to perform acts comprising:

• obtaining estimated motion information of a target frame in a video and reference feature information and a reference reconstructed frame of a reference frame for the target frame;
• determining, using a context extraction model, context information for the target frame based on the estimated motion information, the reference reconstructed frame, and the reference feature information;
• and
• generating, in a conversion between the target frame and a bitstream of the video, a target reconstructed frame of the target frame using a frame coding model and based on at least the context information.
