A system for transmission of imaging metadata comprises a sensor configured to capture audiovisual data and a data transmission device. The data transmission device receives captured audiovisual data from the first sensor and receives metadata, wherein the metadata is metadata of a first type. The data transmission device generates a data structure corresponding to a first frame of a video feed, wherein the data structure is generated in accordance with a predefined data specification, wherein generating the data structure comprises setting an indicator in the data structure to indicate that a second type of metadata should not be read from a first field in the data structure and writing the first metadata to the first field in the data structure. The data transmission device transmits the data structure along with the captured audiovisual data.
