A video signal of an event is digitized as soon as it is recorded and sent to a location remote from the event. The digitized video includes timestamps marking the time at which frames of the video were recorded. A person, watching the event but quite possibly taking no part in the recording of the video, separately enters a text or other type of message into his mobile terminal and sends it to the remote location. The text message, and the portion of the digitized video signal corresponding in time to the message, are automatically marked and placed in a file. The file and the video segment can be made available in an interactive application to other persons with little delay. |
