2Measurement precision

If comprehensive media analysis is performed to accurately detect media trends and assess user interest, then measurement precision improves, but use of energy deteriorates due to increased computational resources required

Engineering Contradiction:

Solution Approach 1:

The patent extracts only the most essential features of media items by generating compact embedding vectors that capture the core semantic information. This extraction approach maintains measurement precision for trend detection while significantly reducing the computational energy required compared to analyzing all raw media data.

Inventive Principle:

Solution Approach 2:

The patent segments the media analysis task into distinct components: video embedding generation, audio embedding generation, and characteristic prediction. This segmentation allows each component to be optimized independently, reducing overall energy consumption while maintaining comprehensive analysis accuracy.

Inventive Principle:

Solution Approach 1:

The patent performs preliminary action by generating embedding vectors that pre-process and compress media information before the actual characteristic detection. This preliminary embedding generation enables faster subsequent analysis while preserving the precision needed for accurate media trend detection and characteristic assessment.

Inventive Principle:

AI summary

Methods and systems for media item characterization based on multimodal embeddings are provided herein. A media item including a sequence of video frames is identified. A set of video embeddings representing visual features of the sequence of video frames is obtained. A set of audio embeddings representing audio features of the sequence of video frames is obtained. A set of audiovisual embeddings is generated based on the set of video embeddings and the set of audio embeddings. Each of the set of audiovisual embeddings represents a visual feature and an audio feature of a respective video frame of the sequence of video frames. One or more media characteristics associated with the media item are determined based on the set of audiovisual embeddings.
