Abstract
Various embodiments provide methods, apparatuses, and computer program products. An example apparatus includes: at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, causes the apparatus at least to: receive, from an encoder, an encoding of at least one picture; receive signaling from the encoder, the signaling comprising information related to a group of at least one post-processing filter; and use the information related to the group of the at least one post-processing filter to infer whether and how to use at least one post-processing filter in the group of the at least one post-processing filter for the at least one picture.

1-110. (canceled)
An apparatus comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, causes the apparatus at least to:
- generate or amend an information message to include an indication whether the information message activates one or more base filters or one or more updated filters identified by filter identifiers equal to target filter identifiers, wherein the target filter identifiers identify target filters, and wherein the target filters are used for post-processing filtering;
- and
- signal the information message to a decoder.
An apparatus comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, causes the apparatus at least to perform:
- receive an information message;
- decode, from the information message, whether one or more base filters or one or more updated filters are to be activated;
- and
- activate the one or more base filters or the one or more updated filters based on decoding the information message.
A method comprising:
- generating or amending an information message to include an indication whether the information message activates one or more base filters or one or more updated filters identified by filter identifiers equal to target filter identifiers, wherein the target filter identifiers identify target filters, and wherein the target filters are used for post-processing filtering;
- and
- signaling the information message to a decoder.
A method comprising:
- receiving an information message;
- decoding, from the information message, whether one or more base filters or one or more updated filters are to be activated;
- and
- activating the one or more base filters or the one or more updated filters based on decoding the information message.
