System and method for synchronizing metadata with audiovisual content

A method used for transmitting a video stream that contains video content from one or more source nodes to one or more destination nodes, wherein the video content comprises consecutive frames, the method comprising:

• receiving the video stream at the one or more source nodes;
• identifying one or more first metadata at the one or more source nodes;
• associating the identified one or more first metadata with one or more specific frames at one or more source nodes;
• associating one or more second metadata with the one or more specific frames, wherein a second metadata conveys a timing information relating to a frame associated with a first identified metadata;
• transmitting the video stream, the identified first metadata and the second metadata from the one or more source nodes to one or more destination nodes;
• receiving the video stream, the first identified metadata and the second metadata at the one or more destination nodes;
• determining a delay at the at the one or more destination nodes based the timing information conveyed by the second metadata;
• and
• based on the delay, modifying association of the first identified metadata with the one or more frames of the video stream at the one or more destination nodes.

A method used for communicating a video stream that contains video content, wherein the video content comprises frames associated with metadata, the method comprising:

• receiving the video stream from a at a node configured to:
• scan the video content for transitions between consecutive frames, each transition indicating significant visual transition relative to other frames of the video data;
• scan the video stream for identified metadata associated with one or more specific frames;
• and
• modify the association of the identified metadata to the same one or more specific frames based on significant visual transitions, wherein the modification synchronizes metadata associated with specific frames at one or more source nodes with metadata associated with the same specific frames at one or more destination nodes.

A method used for communicating a video stream that contains video content, wherein the video content comprises frames associated with metadata, the method comprising:

• receiving the video stream at a node, which is configured to:
• scan the video stream for a first set of metadata associated with one or more frames;
• scan the video stream for a second set of metadata associated with the one or more frames that are associated with the first set of metadata;
• and
• modify the association of the second set of metadata to the same one or more frames as determined by association of the first set of metadata, wherein the modification synchronizes metadata associated with specific frames at one or more source nodes with metadata associated with the same specific frames at one or more destination nodes.

A method used for communicating a video stream that contain video content, wherein the video content comprises frames associated with metadata, the method comprising:

• receiving the video stream at a node, which is configured to:
• scan the video stream for a first set of metadata associated with one or more frames;
• and
• insert a second set of metadata associated to the same one or more frames as determined by association of the first set of metadata, wherein the insertion synchronizes metadata associated with specific frames at one or more source nodes with metadata associated with the same specific frames at one or more destination nodes.
