Notification system for television receivers |
摘要 |
<p>A notification system for television receivers including a visible alarm and/or an audible alarm that is activated when a certain event occurs. An information signal is extracted from a received television signal and is processed to determine the status of an event. If it is determined that the event occurred, then a control signal is sent to the appropriate alarm to activate that alarm, thereby notifying the user of the event's occurrence. The event may include the reception of a text or graphic message, the televising of a certain television program, and the televising of a television program with a specific program rating. The user may also deactivate the alarm. A personal identification number may be used to restrict access to certain features of the notification system. <IMAGE></p> |
