  • Patent number: 11176332
    Abstract: Time dependent media (TDM) content is received, and text features and non-text features are extracted from the TDM content. The TDM content is split into two or more documents. A document, which includes non-text features from the extracted non-text features, is selected. Non-text features in the document are compared to context patterns. When a context pattern matches a non-text feature in the document, a context element linked to the context pattern is linked to the non-text feature as well. The TDM content is modified based on the context element.
