Emergency alert message data structure, emergency alert message processing method and broadcast receiver
First Claim
1. A cable broadcast receiver comprising:
- an in-band signal processor for receiving an audio/video (A/V) broadcasting signal and an emergency alert message over in-band;
a Point Of Deployment (POD) module for receiving a program and channel associated information, and an emergency alert message over Out-Of-Band (OOB); and
an emergency alert message controller for parsing the emergency alert message received by any one of the in-band signal processor and the POD module to determine whether a channel change to an emergency broadcast channel included in the emergency alert message is required, and, if the channel change to the emergency broadcast channel is determined to be required, changing a current channel to the emergency broadcast channel and displaying emergency alert contents in text form on a screen of the emergency broadcast channel if the emergency alert contents are included in the emergency alert message.

Abstract
An emergency alert message data structure, an emergency alert message processing method and a broadcast receiver are disclosed. When a state of emergency where a channel change to an emergency broadcast channel is required occurs, a transmitting stage includes information regarding the emergency broadcast channel and emergency alert contents in text form in an emergency alert message and transmits the resulting emergency alert message. A receiving stage receives the emergency alert message and determines whether the channel change to the emergency broadcast channel included in the emergency alert message is required. If the channel change to the emergency broadcast channel is determined to be required, the receiving stage changes the current channel to the emergency broadcast channel, and displays the emergency alert contents in text form included in the emergency alert message on a portion of a screen of the emergency broadcast channel in a scrolling manner. Therefore, the viewer can more accurately recognize the state of emergency through not only emergency alert broadcast of the emergency broadcast channel which is displayed as a moving image, but also the emergency alert contents which are scrolled on the screen.
