Definitions
- the present invention generally relates to television signal receivers, with or without a display device, and more particularly, to television signal receivers having an emergency alert function capable of, among other things, providing an alert output in accordance with a user selectable alert mode corresponding to the type of emergency event.
- the present invention further relates to user interfaces associated with the emergency alert function.
- Emergency events such as severe weather, natural disasters, fires, civil emergencies, war acts, toxic chemical spills, radiation leaks, or other such conditions can be devastating to unprepared individuals.
- authorities such as the National Weather Service (NWS) and the National Oceanographic and Atmospheric Administration (NOAA) are generally able to detect severe weather conditions prior to the general public.
- NWS National Weather Service
- NOAA National Oceanographic and Atmospheric Administration
- the NWS and NOAA are able to issue early warnings of severe weather conditions which have saved many lives. However, for such warnings to be effective, they must be communicated to their intended recipients.
- Certain specialized radios and scanners are capable of receiving emergency alert signals provided by the NWS and NOAA.
- such devices tend to be dedicated to this use, and generally offer consumers little, if any, functionality beyond monitoring these signals. Accordingly, in order to receive advance warning of weather-related emergencies, consumers are required to purchase a separate, dedicated device, which may be cost-prohibitive to some consumers.
- SAME Specific Area Message Encoding
- an alert output such as an audio message may be provided to alert individuals of the emergency event. While such devices may allow users to select the type of alert output provided in emergency events, the selected type or mode of alert output is used for every type of emergency event.
- Such devices do not allow consumers to designate the manner in which they are alerted on an event-by-event basis.
- the use of a common alert mode for every type of emergency event as described above may be confusing and even dangerous for consumers since they may be unable to readily determine from the alert output whether the particular emergency event is one which may require immediate action (e.g., tornado warning), or one which may be ignored (e.g., thunderstorm watch).
- the use of a common alert mode for every type of emergency event may tend to desensitize consumers towards alert outputs in general since all alert outputs may appear to be similar or the same. As a result, consumers may be more likely to ignore alert outputs and thereby expose themselves to dangerous conditions.
- a television signal receiver having an emergency alert function comprising tuning means for tuning a frequency including emergency alert signals indicating a type of emergency event.
- Processing means enable an alert output responsive to the emergency alert signals, wherein the alert output is provided in accordance with a user selectable alert mode corresponding to the type of emergency event.
- a method for controlling a television signal receiver having an emergency alert function comprises steps of tuning a frequency including emergency alert signals indicating a type of emergency event, and providing an alert output responsive to the emergency alert signals, wherein the alert output is provided in accordance with a user selectable alert mode corresponding to the type of emergency event.

- indicator element 52 may exhibit a yellow color and be illuminated to indicate a statement or advisory level alert.
- indicator element 53 may exhibit an orange color and be illuminated to indicate a watch level alert
- indicator element 54 may exhibit a red color and be illuminated to indicate a warning level alert.
- these different alert levels may represent different emergency events according to the present invention.
- Other colors than those described above, and/or different labels for indicator elements 51 to 54 than those shown in FIG. 5 may also be used according to the present invention.
- indicator elements 52 to 54 may flash
- indicator element 52 may initially blink to attract a user's attention. This blinking may continue for a predetermined time period, or until the user provides an input to television signal receiver 20 such as an input via one of the control elements 55 to 57. Once the predetermined time period elapses or the user provides an input, indicator element 52 may become steadily illuminated. Indicator elements 53 and 54 may operate in a similar manner for watch level alerts and warning level alerts, respectively. Other techniques for combining flashing and steady illumination of indicator elements 52 to 54 may also be used according to the present invention.
- control elements 55 to 57 are operative to enable user control of the alert output(s) of television signal receiver 20, and may for example be embodied as keys, buttons, and/or other control elements which enable users to control the alert output(s) of television signal receiver 20.
- user interface 50 of FIG. 5 is shown as having three control elements. However, the number of such control elements used in practice may be a matter of design choice according to the present invention.
- control element 55 operates as a toggle switch and may be manipulated by a user to turn on and off a visual message such as an NWS text message provided as a closed caption display via display 29. For example, if a visual message is on display 29, control element 55 may be used to turn that message off. Alternatively, if there is no visual message on display 29, but the emergency alert function is activated (e.g., one of indicator elements 52 to 54 is blinking), then control element 55 may be used to turn on the visual message and thereby cause it to be displayed on display 29. In this manner, control element 55 may be used to turn on and off an alert output for a given occurrence of a particular emergency event. Moreover, if television signal receiver
- control element 55 may be used to switch television signal receiver 20 to the on mode and turn on the visual display.
- control element 56 may also operate as a toggle switch in a manner similar to control element 55 described above.
- control element 56 may be manipulated by a user to turn on and off an audio message such as an NWS audio message or a message from the All Hazards Alert System provided via speaker 25.
- control element 56 may be used to turn that message off.
- the emergency alert function e.g., one of indicator elements 52 to 54 is blinking
- control element 56 may be used to turn on the audio message and thereby cause it to be output via speaker 25.
- control element 56 may be used to turn on and off an alert output for a given occurrence of a particular emergency event. Moreover, if television signal receiver 20 is in the off/standby mode, control element 56 may be used to switch television signal receiver 20 to the on mode and turn on the audio message.
- control element 57 may be manipulated by a user to turn off an alarm such as a chime, siren or the like provided via speaker 25.
- control element 57 may be used to turn the alarm off.
- control elements 55 and 56 may also be used to turn off the alarm.
- the chime is a gentle but recognizable sound, while the siren is a loud and urgent sound.
- Such an alarm may for example start at a given volume level and gradually increase to a maximum volume level established by a user. Accordingly, by allowing users to turn off the alarm using any of the control elements 55 to 57, the present invention advantageously enables users to quickly turn off the alarm before it becomes too annoying.
- control elements 55 to 57 not be used to completely turn off indicator elements 51 to 54 to ensure that users are provided with at least one alert output when the emergency alert function is activated.
- Other labels for control elements 55 to 57 than those shown in FIG. 5 may also be used according to the present invention. Accordingly, user interface 50 of FIG. 5 is only an example and other types of indicators, displays and/or control means may be provided according to the present invention.
- the present invention provides a television signal receiver having an emergency alert function capable of, among other things, providing an alert output in accordance with a user selectable alert mode corresponding to the type of emergency event.
- the present invention may be applicable to various apparatuses, either with or without a display device.
- the phrase "television signal receiver” as used herein may refer to systems or apparatuses capable of receiving and processing television signals including, but not limited to, television sets, computers or monitors that include a display device, and systems or apparatuses such as set-top boxes, video cassette recorders (VCRs), digital versatile disk (DVD) players, video game boxes, personal video recorders (PVRs), computers or other apparatuses that may not include a display device.
