INLINE KEYED METADATA

摘要

An encoding system may include a metadata manager, a key manager, and an encoder. The metadata manager may interface with one or more metadata sources to determine whether to include a metadata item from the one or more metadata sources. The key manager may determine whether the metadata item can be represented using one of already-allocated keys or an inline key must be used to represent the metadata item. The encoder may encode the metadata. If an inline key must be used to represent the metadata item, the encoder may associate the inline key and the type of the metadata item to the media file, and the encoder may encode the metadata item using the inline key in the media file.

1. An encoding system, comprising:
a metadata manager interfacing with one or more metadata sources to select metadata item(s) for inclusion in coded multimedia data; a key manager to determine, in response to a newly-provided item of metadata from the metadata manager, whether the metadata item matches a type of metadata defined at an onset of a coding session, and when the newly-provided metadata item does not match the type of metadata defined at the onset of the coding session, representing the new metadata item as an inline key, an encoder to encode the metadata item in the coded multimedia data, wherein the inline key is identified as a first key value having a value that matches a reservation identifier provided at the onset of the coding session and a second key value that is unique to the newly-provided metadata item.
