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.

Claims3

Dependent claims

An audio decoding method, comprising:

receiving an encoded bitstream, the encoded bitstream including:
HE AAC version 1 or HE AAC version 2 encoded input audio data;
and
metadata indicating a loudness value of dialog portions of the input audio data;
decoding, using an HE AAC version 1 or HE AAC version 2 decoder, the HE AAC version 1 or HE AAC version 2 encoded input audio data to provide decoded audio data;
receiving a flag indicating whether or not to perform loudness normalization processing on the decoded audio data;
when the flag indicates to perform loudness normalization processing on the decoded audio data:
obtaining a user-controlled target loudness value;
extracting, from the metadata, the loudness value of dialog portions of the input audio data;
determining a loudness normalization adjustment value based on the user-controlled target loudness value and the loudness value of dialog portions of the input audio data;
and
applying the loudness normalization adjustment value to the decoded audio data to provide loudness normalized output audio data;
and
when the flag indicates not to perform loudness normalization processing on the decoded audio data:
disabling the loudness normalization processing and passing through the decoded audio data unchanged.
