A device and method for simultaneously capturing a content video stream comprising video of content presented during a live presentation, a content audio stream comprising audio accompanying the presented content, a presenter video stream comprising video of the presenter recorded via a video camera, and a presenter audio stream comprising audio of the presenter recorded via a microphone. The content audio stream and the presenter audio stream are mixed into a combined content and presenter audio stream, the content video stream is combined with the presenter video stream into a combined content and presenter video stream, and the combined content and presenter audio stream and the combined content and presenter video stream are encoded into a combined AV data stream. The combined AV data stream is distributed via one or more output channels, for example to a digital sink via an HDMI connection.
