Abstract
A system comprising a processor, wherein the processor is configured to: acquire a sports broadcast video, extract an audio signal from the sports broadcast video, and convert the extracted audio signal into text by using a speech recognition technique, detect a sudden change in volume in the audio signal and identify a highlight portion of a game based on the detected sudden change in volume, obtain game information from an external database, and generate a prompt sentence for instructing a generative AI model to generate a text based on the obtained game information and the identified highlight portion of the game.
Claims20
A system comprising:
- circuitry configured to:
- receive, via a communication interface coupled to a packet-switched network, a video input signal comprising broadcast video data, and separate an audio signal from the video input signal to generate audio data;
- execute speech recognition processing on the audio data to generate character information associated with time information, and calculate a temporal change of an acoustic quantity based on the audio data;
- detect a change of the acoustic quantity satisfying a predetermined condition to specify time information of an excitement event, and acquire event information, group information, and participant information from an external data source;
- associate the acquired event information, group information, and participant information with the time information and the character information to generate structured data, and generate a prompt sentence based on the structured data, the prompt sentence including instructions relating to an event situation, an event content, and an output format;
- execute inference processing using a generative neural network model with the prompt sentence as input to generate a natural language document, and record the natural language document as related information in association with the time information of the excitement event;
- and
- synchronize the natural language document with the time information, superimpose the natural language document on distribution data, and continuously distribute the broadcast video data together with the related information to a terminal device via the communication interface.
