Metadata time marking information for indicating a section of an audio object

摘要

The application relates to a method for encoding time marking information within audio data. According to the method, time marking information is encoded as audio metadata within the audio data. The time marking information indicates at least one section of an audio object encoded in the audio data. E.g. the time marking information may specify a start position and an end position of the section or only a start position. The at least one section may be a characteristic part of the audio object, which allows instant recognition by listening. The time marking information encoded in the audio data enables instantaneous browsing to a certain section of the audio object. The application further relates to a method for decoding the time marking information encoded in the audio data.

1. A method for encoding time marking information within audio data, wherein the audio data is a bitstream, the method comprising:
encoding time marking information as audio metadata within the audio data, thereby forming a joint bitstream, wherein the time marking information indicates a plurality of sections of an audio object in the audio data; wherein the time marking information is encoded in multiple positions of the audio data; wherein the multiple positions occur at a particular occurrence rate in the audio data bitstream; wherein time marking information in a given position of the multiple positions is specified in relation to the occurrence of the given position in the audio data bitstream; and wherein the time marking information is encoded in a metadata container of the joint bitstream; thereby enabling a corresponding decoder to start playback of the audio object at a beginning of a section of the audio object indicated by the time marking information.
