A system and method for broadcast response generally employing RDS, DARC, or similar technology is provided, including a method for responding to a broadcast comprising extracting an event identifier from a broadcast signal; detecting a response by a user to the broadcast signal; polling a communications device to determine a user identifier; and communicating the event identifier and the user identifier when the user response is detected.

A broadcast receiving device for receiving a transmitted service by using an MPEG Media Transport (MMT) protocol includes a tuner configured to receive Service Layer Signaling (SLS); a memory storing one or more instructions; and a processor configured to execute the one or more instructions stored in the memory to obtain information of one or more contents constituting the service, from an MMT Package (MP) table included in the SLS, determine whether there is second content that is the same as first content being currently received through a first transfer path and is received through a different transfer path from a transfer path of the first content, among the one or more contents, based on the information of the one or more contents, and perform, when there is the second content, a handoff of a content receiving channel from the first transfer path to a second transfer path corresponding to the second content to receive the second content.

In response to an operation such as power-on or power-off, channel change and sound volume change, a television set combined with a personal computer automatically makes e-mail with information in a predetermined format indicative of the operation attached. The e-mail is automatically sent to another television set to inform the other television set of operation of the own television set. On the other hand, the e-mail can be sent to a rating company for audience share survey. The television set automatically reads the received e-mail and attachment to change the indication of display. The television set has storage of the received information for analysis of an abnormality. Abnormality can be also sensed through abnormal act on the remote controller apt to be taken by a person in panic or off the truck. The television set refuses information from unknown address for blocking an attack of a stranger.
