A digital television (DTV) transmitter / receiver and a method of processing data in the DTV transmitter / receiver are disclosed. In the DTV transmitter, a pre-processor pre-processes the enhanced data by coding the enhanced data for forward error correction (FEC) and expanding the FEC-coded enhanced data. A data formatter generates enhanced data packets including the pre-processed enhanced data and inserts known data to at least one of the enhanced data packets. A first multiplexer multiplexes the enhanced data packets with main data packets including the main data. And, an RS encoder RS-codes the multiplexed main and enhanced data packets, the RS encoder adding systematic parity data to each main data packet and adding RS parity place holders to each enhanced data packet. Herein, the RS encoder may insert non-systematic RS parity data or null data into the RS parity place holders included in each enhanced data packet.

A method for reporting a user's emergency condition by sending an emergency help request message in a TCP / IP format to an emergency service center (ESC). The help request message may be sent over the Internet to advantageously harness the data transmission resources provided by the Internet. A support service provider may commercially provide such an emergency reporting service to a group of subscribers. The service provider may receive emergency requests from the subscribers and may send those requests over the Internet to the emergency service center. The service provider may also convert any non-TCP / IP message received from the subscriber into a TCP / IP message prior to sending the message to the ESC. A per-usage fee or a flat subscription fee may be charged by the service provider to allow users to report emergency conditions over the Internet. The support service provider thus coordinates the emergency help on behalf of the user. Internet-based emergency message delivery may be useful in many situations, for example, when the person in need of help is mute, disabled or in a situation that prevents the person from orally requesting emergency help from the ESC.

When a transmission device transmits a broadcast service signal using a radio signal, the transmission device determines whether there is a moving body that is moving at high speed toward or away from the transmission device, and calculates the amount of Doppler shift of a radio frequency due to high speed movement based on the movement speed of the moving body when there is such a high-speed moving body.
