Abstract
A method of transmitting metadata document associated with a video, each metadata document comprising format information and time information, comprising the steps of: identifying, within every metadata document, distinct elements by their format information and storing elements of equivalent format within sets; multiplexing, within each set, elements of common time information; compressing at least one of the said multiplexed elements; and transmitting a bit-stream containing said at least one multiplexed element.
Claims13
A method of transmitting metadata documents associated with a video, each metadata document comprising format information and time information, comprising the steps of:
- identifying, within every metadata document, distinct elements by their format information and storing elements of equivalent format within sets;
- multiplexing, within each set, elements of common time information;
- compressing at least one of the said multiplexed elements;
- and
- transmitting a bit-stream containing said at least one multiplexed element.
A metadata transmitter for synchronizing metadata documents associated with a video, each metadata document comprising format information and time information, comprising:
- an identifier for identifying, within every metadata document, distinct elements by their format information and storing elements of equivalent format within sets;
- a multiplexing encoder for multiplexing, within each set, elements of common time information;
- a compressor for compressing at least one of the said multiplexed elements;
- and
- a transmitter for transmitting a bit-stream containing said at least one multiplexed elements.
A method of progressively receiving metadata documents associated with a video that is described in multimedia documents, comprising the steps of:
- receiving compressed multiplexed elements of metadata documents;
- un-compressing the received multiplexed elements;
- reconstructing different metadata documents from the obtained multiplexed elements;
- associating these metadata documents to the corresponding video multimedia documents for rendering.
