22 Claims

1. A method comprising:

receiving a media bitstream comprising one or more media units and a container, wherein the container comprises at least a first enhancement information message and a second enhancement information message, wherein the first enhancement information message comprises or identifies a neural network, and the second enhancement information message comprises an update to the neural network;

wherein the received media bitstream comprises a third enhancement information message;

decoding the one or more media units;

updating the neural network based on the update; and

using the updated neural network to enhance or filter the decoded one or more media units within a temporal scope determined with the third enhancement information message, a spatial scope determined with the third enhancement information message, or a spatio-temporal scope determined with the third enhancement information message, wherein the third enhancement information message indicates that the updated neural network is active for use.
