  • channel selection controller 260 channel selection controller 260.
  • the ON/OFF status of television 200 is controlled by an operator using either a remote control or a manual switch to generate an ON/OFF signal that controls low power mode controller 255.
  • the indicated circuits of television 200 operate and receive electrical power even when power has been disabled i.e., placed in the standby mode) by enabling the OFF signal through the ON/OFF switch.
  • Television antenna 205 receives video RF signals from TV broadcast stations, such as TV/radio broadcast facility 110, and transfers these RF signals to RF tuner 210. Even when television 200 is in standby mode, RF tuner 210, under the direction of channel selection controller 260, downconverts a selected frequency channel of the received RF signal to an IF signal, which is transferred to IF mixer 215. IF mixer 215 downconverts the IF signal to baseband video and audio signals that normally are processed by the numerous circuit elements in standby mode circuitry 216. The baseband output of IF mixer 215 also is monitored by emergency code detector 250.
  • Standby mode circuitry 216 comprises the portions of television 200 that are required for the video and audio conversion of received signals.
  • Standby mode circuitry 216 includes video detector 220, audio detector 225, video display 230, and speakers 235.
  • Video detector 220 and audio detector 225 convert the baseband signals from IF mixer 215 to video signals and audio signals that are sent to video display 230 and audio speakers 235, respectively.
  • Video display 230 provides means for viewing the received broadcast image(s) and speakers 235 provide the audio output associated with the received signals.
  • standby mode circuitry 216 may only comprise audio circuits providing the functions of a radio receiver.
  • standby mode circuitry 216 The ON/OFF status of standby mode circuitry 216 is controlled by low power mode controller 255. Standby mode circuitry 216 is fully “ON" or operational when low power mode controller 255 is enabled by the ON/OFF switch or by emergency code detector 250 during an EBS alarm condition. Otherwise, standby mode circuitry 216 is in the OFF (or standby) mode.
  • Emergency code detector 250 monitors the received signal from IF mixer 215 to detect the presence of emergency code 180. If emergency code 180 is detected, emergency code detector 250 sends an activation (or "ON") signal to low power mode controller 255 that causes lower power mode controller 255 to apply full power to standy mode circuitry 216. In one embodiment, low power mode controller 255 maintains full power until disabled by the reception of an OFF command signal. In an alternate embodiment, low power mode controller 255 may maintain the emergency operational power level for a pre-determined or program-selected duration of time. For instance, the owner of television 200 may program select an emergency operational power duration of 60 minutes. After 60 minutes has expired without the reception of an EBS message, the power for standby mode circuit 216 will return to the OFF or "standby" level.
  • emergency code detector 250 also may send a channel selection signal to channel selection controller 260, which controls the channel frequency to which RF tuner 210 is tuned.
  • emergency code detector 250 may send a channel selection signal that causes channel selection controller 260 to tune to a particular default channel that may be established by a telecommunication standard.
  • emergency code detector 250 may send a channel selection signal that causes channel selection controller 260 to simply remain on the channel in which emergency code 180 was detected (i.e., no change). Thus, channel selection controller 260 tunes RF tuner 210 to the last operator-selected channel.
  • channel selection controller 260 may be placed in a channel-sequencing mode in which each channel is selected for a pre-determined or programmable period of time, or until the strongest signal is received.
  • emergency code 180 may additionally comprise a channel selection field that is detected by emergency code detector 250. The channel selection field contains the value of the field to which channel selection controller 260 tunes RF tuner 210. Thus TV/radio station 110 not only may remotely activate television 200, it also may remotely tune television 200 to any channel desired.
  • TV/radio station 110 transmitted emergency code 180 during an emergency, TV/radio station 110 will subsequently broadcast some type of emergency programming, such as audio emergency message(s) 181, video emergency messages(s) 182, or a live news report from a studio represented by broadcast program data 165.
  • some type of emergency programming such as audio emergency message(s) 181, video emergency messages(s) 182, or a live news report from a studio represented by broadcast program data 165.
  • audio emergency message(s) 181, video emergency messages(s) 182 or a live news report from a studio represented by broadcast program data 165.
  • tuning RF tuner 210 to a particular default channel established by a telecommunication standard ensures that television 200 will be tuned to an emergency broadcast channel when it is remotely activated by the transmission of emergency code 180.
  • FIGURE 3 depicts flow chart 300, which illustrates a broadcast operation for transmitting an emergency message to exemplary television 200 operating in low-power mode in accordance with one embodiment of the present invention.
  • Flow chart 300 represents the operation of EBS 100 and television 200 during an emergency situation.
  • TV/radio broadcast facility 110 receives an incoming emergency alert or alarm indication from one or more public safety agencies associated with EBS 100, such as FEMA 131, NWS 132, police service 133, and service fire 134, or others (process step 305).
  • TV/radio broadcast facility 110 inserts emergency code 180 associated with the emergency alarm into the RF signal being broadcast (process step 310).
  • the "normal" audio program may be interrupted with the insertion and transmission of an audio message or tone associated with the emergency code.
  • TV/radio broadcast facility 110 may enable and transmit a pre-recorded or st ' ored audio and/or video message that is associated with the indicated alarm.
  • TV/radio broadcast facility 110 may insert and transmit a live audio/visual emergency message as it is directly received from one or more public safety agencies or from a news studio (process step 315).
  • Television and radio receivers in the coverage area of TV/radio broadcast facility 100 receive the transmitted RF message. These receivers include television and/or radio receivers which are in the standby or low power mode of the present invention (process step 320). Subsequently, emergency code detector(s) 250 in the television and/or radio receivers detect the presence of the emergency code and/or message in the RF signal (process step 325). The emergency code detector(s) 250 switch their respective television or radio receivers from standby to the operational or "ON" state (process step 330).
  • Channel selection controller(s) 260 associated with switched-ON receiver cause the associated TV or radio receiver to tune to a default or selected emergency channel.
  • each channel selection controller 260 may cause the RF tuner to set the volume of the radio or television to a "HIGH" level for emergency notification purposes (process step 340).
  • TV/radio receiver may play or display (as applicable) any transmitted emergency audio or video message(s) associated with emergency code 180 (process step 340
  • any person in the vicinity of a radio or television receiver which may be in the OFF (or standby) mode will still be alerted to the presence of an emergency situation.
  • the disabled radio or television receiver detects the presence of an EBS alarm indication, it places the receiver in the ON condition, enables an emergency broadcast frequency or channel, optionally sets the volume to the HIGH level, and plays/displays the emergency message.
  • the HIGH volume level increases the likelihood that individuals within hearing range, including sleepers, will be alerted to the alarm condition.

Abstract

La présente invention concerne un système d'avertissement d'urgence, utilisé dans un dispositif comprenant un récepteur de fréquence radio (RF), qui peut recevoir un signal de radiodiffusion ou un signal de télédiffusion, lorsque ce dispositif est en mode veille. Ce système d'avertissement d'urgence comprend un détecteur, qui est couplé au récepteur RF, afin de détecter un code d'urgence dans le signal de radiodiffusion ou de télédiffusion reçu et de produire un premier signal. Ce système d'avertissement d'urgence comprend également une unité de commande de mode veille, qui est couplée au détecteur et reçoit le premier signal issu dudit détecteur. Cette unité de commande de mode veille, en réponse au premier signal, commute le dispositif du mode veille à un mode actif, dans lequel le récepteur RF traite et lit le signal de radiodiffusion ou de télédiffusion reçu.
