Television advertisement monitoring system
The present invention discloses systems for monitoring advertisements. A system for monitoring advertisements in a broadcast television channel in accordance with the present invention comprises a sound level monitor for monitoring an audio level of a first broadcast television channel, a data tagger, coupled to the sound level monitor, for tagging a start and an end of an advertisement segment within the first broadcast television channel, and a receiver, wherein when the receiver is first tuned to the first broadcast channel and then tuned to a second broadcast channel, an on-screen display is displayed on a monitor displaying the second broadcast channel, the OSD being displayed when the end of the advertisement segment within the first broadcast channel occurs.
1. A method of monitoring a first broadcast, comprising:
joining a multicast transmission having program guide information comprising information about the first broadcast on a first broadcast channel of a plurality of broadcast channels comprising registering a monitoring request with a server;
receiving the information about the first broadcast via the joined multicast transmission while receiving a second broadcast on a second broadcast channel of the plurality of broadcast channels comprising receiving the information about the first broadcast via the joined multicast transmission from the server; and
providing an on screen display (OSD) signal while receiving the second broadcast on the second broadcast channel according to the information about the first broadcast received on the joined multicast transmission;
wherein the first broadcast comprises an advertisement pod, and the OSD indicates an end of the advertisement pod.
2. The method of claim 1 , wherein:
the information comprises information designating the end of the advertisement pod;
the method further comprises determining if the first broadcast channel is a base broadcast channel;
receiving the information about the first broadcast via the joined multicast transmission while receiving a second broadcast on a second channel comprises:
monitoring for the information designating the end of the advertisement pod only if the first broadcast channel is a base broadcast channel.
3. The method of claim 2 , wherein the first broadcast channel is determined to be the base broadcast channel according to user selected input identifying the channel as the base broadcast channel.
4. The method of claim 2 , wherein the first broadcast channel is determined to be the base broadcast channel according to a time period in which the first broadcast channel is tuned before tuning the receiver from the first broadcast channel to the second broadcast channel.
5. The method of claim 4 , wherein the time period is user defined.
6. The method of claim 1 , wherein the information comprises information about the plurality of broadcast channels.
7. The method of claim 1 , wherein the information comprises information about only a subset of the plurality of broadcast channels.
8. The method of claim 1 , wherein the multicast transmission is a user datagram protocol (UDP) multicast transmission.
9. A receiver, comprising:
a tuner, for selectively receiving one of a plurality of broadcast channels, including a first broadcast channel transmitting a first broadcast and a second broadcast channel transmitting a second broadcast;
wherein the receiver joins a multicast transmission having program guide information comprising information about a first broadcast on the first broadcast channel of the plurality of broadcast channels by registering a monitoring request with a server, receives the information about the first broadcast via the joined multicast transmission while receiving a second broadcast on the second channel of the plurality of broadcast channels by receiving the information about the first broadcast via the joined multicast transmission from the server, and provides an on screen display (OSD) signal while receiving the second broadcast on the second channel of the plurality of broadcast channels according to the information about the first broadcast received on the joined multicast transmission and the first broadcast comprises an advertisement pod, and the OSD indicates an end of the advertisement pod.
10. The receiver of claim 9 , wherein:
the information comprises information designating the end of the advertisement pod;
the receiver further determines if the first broadcast channel is a base broadcast channel and monitors for the information designating the end of the advertisement pod only if the first broadcast channel is a base broadcast channel.
11. The receiver of claim 10 , wherein the first broadcast channel is determined to be the base broadcast channel according to user selected input identifying the channel as the base broadcast channel.
12. The receiver of claim 10 , wherein the first broadcast channel is determined to be the base broadcast channel according to a time period in which the first broadcast channel is tuned before tuning the receiver from the first broadcast channel to the second broadcast channel.
13. The receiver of claim 12 , wherein the time period is user defined.
14. The receiver of claim 9 , wherein the information comprises information about the plurality of broadcast channels.
15. The receiver of claim 9 , wherein the information comprises information about only a subset of the plurality of broadcast channels.
16. The receiver of claim 9 , wherein the multicast transmission is a user datagram protocol (UDP) multicast transmission.
