Multiple description coding using neural fields

An apparatus for multiple description coding, the apparatus comprising:

• at least one processor;
• and
• at least one memory including program code;
• and
• wherein the at least one memory and the program code are configured to, with the at least one processor, cause the apparatus at least to:
• generate a plurality of descriptions using a neural network implementing a neural field, each of the plurality of descriptions comprising a respective first set of neural network parameter values obtained via training a respective instance of the neural network with a different respective subset of a set of sampled coordinate values of a multimedia object or of a larger second set of neural network parameter values corresponding to the multimedia object, wherein any two or more descriptions of the plurality of descriptions are combinable to generate a reconstruction of the multimedia object;
• and
• direct two or more of the plurality of descriptions via an external communication link.

• and
• combine any two or more descriptions of the plurality of descriptions to generate a combined description providing a higher quality of reconstruction of the multimedia object than any one description of the plurality of descriptions.
