Abstract
Methods, systems and computer readable medium with program instructions for providing contextually relevant information for multimedia content streaming through a rendering device, includes detecting a selection of the multimedia content for rendering on the rendering device. An audio signal of the multimedia content is retrieved and analyzed to generate an audio fingerprint. The generated audio fingerprint is used to identify the multimedia content that is selected for rendering. Contextually relevant content for a portion of the multimedia content being rendered on the rendering device is dynamically retrieved from one or more sources and mapped to data associated with the portion of the multimedia content. The mapping results in the rendering of the relevant content during the rendering of the portion of the multimedia content and provides additional information that is contextually relevant to the portion of the multimedia content that is currently being rendered on the rendering device.
