A method for graphically indicating presence, identity, and action with respect to a media post transmitted by a client device and displayed on a shared display. Metadata indicating the identity of a user is logically associated with visual media to form a media stream, which is transmitted to the shared display. The transmitted media stream is then decoded to recover the transmitted metadata. The media post is displayed on the shared display and the presence of a client device media stream, the identity of the current user of the device generating the stream, and an action associated with the user interaction with the client device, is then graphically indicated on the display, using the recovered metadata.
