Systems and methods for efficient transmission of imaging metadata

A method for transmission of imaging metadata, the method performed by a system comprising a first sensor configured to capture audiovisual data and a data transmission device comprising one or more processors, the method comprising:

• receiving the captured audiovisual data from the first sensor;
• receiving first metadata, wherein the first metadata is metadata of a first type relating to one or both of acquisition and processing of the audiovisual data;
• generating 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 relating to video format should not be read from a first field in the data structure, wherein the indicator comprises a bit in the data structure that indicates, according to an audiovisual data transport protocol, whether the first field should be read for video format data;
• and
• writing the first metadata to the first field in the data structure;
• and
• transmitting the data structure along with the captured audiovisual data.

A non-transitory computer-readable storage medium storing instructions for transmission of imaging metadata, the instructions configured to be executed by one or more processors of a system comprising a first sensor configured to capture audiovisual data and a data transmission device, wherein execution of the instructions by the one or more processors causes the data transmission device to:

• receive the captured audiovisual data from the first sensor;
• receive first metadata, wherein the first metadata is metadata of a first type relating to one or both of acquisition and processing of the audiovisual data;
• generate 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 relating to video format should not be read from a first field in the data structure, wherein the indicator comprises a bit in the data structure that indicates, according to an audiovisual data transport protocol, whether the first field should be read for video format data;
• and
• writing the first metadata to the first field in the data structure;
• and
• transmit the data structure along with the captured audiovisual data.
