Abstract

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.

Claims

1. A television receiver which receives and processes a television signal to produce a video image, the television receiver comprising:

means for receiving the television signal containing message data, the message data being independent of the video image;

alarm means, internally coupled to the television receiver for indicating the occurrence of an event;

an Interactive Program Guide (IPG); and

control processor means for executing commands to operate the television receiver, including;

means for extracting the message data from the television signal, wherein the extracting means processes data received during the vertical blanking interval of the television signal;

means for processing the message data to determine a status of the event, including means for receiving a program rating value from an IPG service and for activating the alarm means only if the program rating value is greater than a predetermined value; and

means for selectively activating the alarm means responsive to the determined event status.

2. A television receiver according to claim 1, wherein the event is a message transmitted during the vertical blanking interval of a predetermined channel and the alarm means is activated to indicate that the message has been received.

3. A television receiver according to claim 2, further comprising display means for displaying said received message.

4. A television receiver according to claim 2, wherein the alarm means comprises a visible alarm.

5. A television receiver according to claim 4, wherein the visible alarm is a light-emitting diode.

6. A television receiver according to claim 5, further including means for causing the light-emitting diode to blink when said alarm means is activated.

7. A television receiver according to claim 2, wherein the alarm means comprises an audible alarm which sounds when said alarm means is activated.

8. A television receiver of claim 1, further comprising means for selectively deactivating the alarm means.

9. A television receiver according to claim 1, wherein the alarm means comprises an audible alarm.

10. A television receiver which receives and processes a television signal to produce a video image, the television receiver comprising:

means for receiving the television signal containing message data, the message data being independent of the video image;

alarm means, internally coupled to the television receiver for indicating the occurrence of an event;

an Interactive Program Guide (IPG) which receives and processes IPG data; and

control processor means for executing commands to operate the television receiver, including;

means for extracting the message data from the television signal, wherein said extracting means processes data received during the vertical blanking interval of the television signal and includes means for extracting a message data from the IPG data;

means for processing the message data to determine a status of the event, including address processing means for extracting an address field from the message and for determining if the message is properly addressed; and

means for selectively activating the alarm means responsive to the determined event status.

11. A television receiver according to claim 10, wherein the address processing means further includes:

means for storing a predetermined address value; and

means for comparing the message address value to the predetermined address value and for activating the alarm means only if the message address value equals the predetermined address value to indicate that the message has been received.

12. A television receiver which receives and processes a television signal to produce a video image, the television receiver comprising:

means for receiving the television signal containing message data, the message data being independent of the video image;

alarm means, internally coupled to the television receiver for indicating the occurrence of an event, wherein the event is the televising of a predetermined television program; and

control processor means for executing commands to operate the television receiver, including;

means for extracting the message data from the television signal which processes data received during the vertical blanking interval of the television signal;

means for processing the message data to determine status of the event, including means for comparing all programs available to be received to the predetermined program and for activating the alarm means to indicate that the predetermined television program can be received; and

means for selectively activating the alarm means responsive to the determined event status.

13. A method of controlling and providing notice of an event through a television receiver comprising the steps of:

receiving a television signal including an information signal of a first type;

receiving local information including an information signal of a second type different from the first type;

processing the information signal of the first type and the second type to determine the status of the event; and

activating selectively an alarm indicating the occurrence of the event if the determined status of the event indicates that the event has occurred.

14. A method according to claim 13, wherein the step of extracting message data from the television signal includes processing data received from an interactive program guide (IPG) service.

15. A notification system contained in a television receiver which receives and processes a television signal to produce a video image, the system comprising:

means for receiving the television signal including an information signal of a first type;

means for receiving local information including an information signal of a second type different from the first type;

processing means for processing the information signal of the first type and of the second type;

alarm means, internally coupled to the processing means for indicating the occurrence of an event; and

means for selectively activating the alarm means responsive to processed information signals of the first type and of the second type.

16. A notification system contained in a television receiver as claimed in claim 15, wherein the processing means operates the television receiver responsive to the processed information signal of the first type and of the second type.

17. A notification system contained in a television receiver as set forth in claim 16, wherein

the information signal of the second type is a predetermined rating threshold value, and the information signal of the first type is a rating value;

and

the processing means processes the information signal of the first type and of the second type to determine the event of the rating value being greater than the rating threshold, and activates the alarm means if it is determined that the event has occurred.

18. A notification system contained in a television receiver as set forth in claim 15, further comprising

a second television signal including a predetermined television program and an information signal of a third type, the third type including a rating value;

and wherein

the television receiver displays the predetermined television program,

the information signal of the second type is a rating threshold;

the information signal of the first type is message data received by the television receiver; and

the processing means includes means for

1) processing the information signal of the first type and of the second type to determine a first event of the rating value being greater than the rating threshold,

2) processing the information signal of the first type to determine a second event of the presence of message data for the television receiver, and

3) activating the alarm means if it is determined that the event has occurred, wherein the event is deemed to have occurred if the first event or the second event has occurred.
