Abstract
System and method of automatic enrichment of information for audio streams including an intelligent search engine which—by means of the ID3 metadata extracted from the audio file—completes a search over unstructured data sources and produces a structured database, from which a composing audio/video software automatically produces a video stream streaming with the collected additional information.
Claims20
A system for automatic enrichment of information for audio streams that automatically completes, in real time, multimedia contents from multiple sources, transforming the multimedia contents into a single audio/video stream viewable through a streaming player, and distributing said single audio/video stream on devices having a screen, said multimedia contents assembled together through a synergistic work between hardware and a non-transitory computer-readable medium on which is stored a computer program, said hardware comprising:
- an audio stream reader module which initially extracts all metadata available in an associated audio file being played, the extracted metadata being ID3 metadata and being information regarding the audio stream being played;
- a data analysis module that, through the extracted ID3 metadata and information contextual to reproduction of the audio stream, is adapted to process information necessary for production of the single audio/visual stream enriched with researched and aggregated data;
- said computer program comprising instructions, which when executed by a computer, causes the computer to perform steps of:
- starting from the ID3 metadata extracted from the audio stream being played and based on said information regarding the audio stream being played, searching in real time for additional information regarding the audio stream being played and reconstructing further metadata concerning the additional information by performing automatic searches for the additional information on each of the Web, Social Networks and other sources of unstructured data using an intelligent search engine;
- storing the ID3 metadata extracted from the audio stream being played and the further metadata concerning the additional information found by said intelligent search engine to a single database;
- and
- using an audio/video composer, extracting data, including the additional information found by said intelligent search engine, from the single database and intregrating the audio stream being played with the extracted data from the single database into the single audio/video output stream enriched with the researched and aggregated data,
- wherein the extracted data comprises data necessary for creating the single audio/video output stream, in which the video of the single audio/video output stream is an automatic composition of the additional information collected by the search engine.
The system of clam 5, wherein the computer program further comprises instructions that cause the computer to execute showing said promotional messages in graphic form on the display device instead of audio form, allowing the user to choose which mode to follow and activating audio mode automatically when the screen is not in operation for a given period of time.
