Abstract: A multimedia query system is described that includes a multimedia capture system configured to capture raw multimedia data comprising at least one of raw video data or raw audio data, a metadata engine configured to extract one or more anchor points of metadata from the raw multimedia data and to store the one or more anchor points of metadata, wherein the anchor points of metadata includes references to respective portions of the raw multimedia data. The multimedia query system further includes a storage engine configured to store the raw multimedia data, a recall engine configured to receive a query and to apply the query to the one or more anchor points of metadata to identify one or more raw multimedia data candidates from the portions of the raw multimedia data, and a query engine configured to generate a response to the query based on the one or more raw multimedia data candidates.
