Summaries of broadcasts of live events are generated based on intensities of audio signals captured during the live events. Streams of multimedia including video signals and audio signals are captured by one or more cameras. The video signals are processed to identify specific activities of interest (e.g., plays of a sporting event) during the live event. Audio signals captured concurrently with the video signals are processed to determine their respective intensities or other acoustic characteristics. The activities of interest are ranked based on intensities of the audio signals. A multimedia stream representing a summary of a media program and includes the highest-ranking video signals and corresponding audio signals is generated and transmitted to one or more devices of viewers.

Embodiments of the present application provide a stream media feature extraction method, a multi-modal content representation model establishment method, a stream media feature extraction device and an electronic device, relating to the technical field of artificial intelligence. The method extracts the content features of video clips in stream media through a pre-established multi-modal content representation model.
