US 2021/0280200 A1 · ADAPTIVE PROCESSING WITH MULTIPLE MEDIA PROCESSING NODES

Abstract

Techniques for adaptive processing of media data based on separate data specifying a state of the media data are provided. A device in a media processing chain may determine whether a type of media processing has already been performed on an input version of media data. If so, the device may adapt its processing of the media data to disable performing the type of media processing. If not, the device performs the type of media processing. The device may create a state of the media data specifying the type of media processing. The device may communicate the state of the media data and an output version of the media data to a recipient device in the media processing chain, for the purpose of supporting the recipient device's adaptive processing of the media data.

Claims6

Dependent claims

An audio decoding method, comprising:

receiving an encoded bitstream, the encoded bitstream including encoded input audio data and processing state metadata including a loudness value;
decoding the encoded input audio data;
receiving signaling data indicating whether loudness processing should be performed on the decoded audio data;
when said signaling data indicates that loudness processing should be performed on the decoded audio data:
obtaining the loudness value from the processing state metadata;
and
normalizing loudness of said decoded input audio data according to the loudness value, to provide output audio data.
