Method and apparatus for determining and displaying the service level of a digital television broadcast signal
First Claim
1. An apparatus comprising:
- a digital television receiver to receive a digital television broadcast signal, the digital television broadcast signal including an Internet Protocol (IP) based data test stream located on a Packet Identifier (PID) of the digital television broadcast signal having a plurality of sequentially numbered IP data packets used to determine a service level of the digital television broadcast signal being received on a channel; and
a service level determiner to determine the service level of the digital television broadcast signal based upon a loss of IP data packets from the IP based data test stream and to cause the service level to be displayed, wherein the service level determiner measures a number of IP data packets of the IP based data test stream received by the digital television receiver over a predetermined interval and determines a data packet loss percentage value for the IP based data test stream by calculating a ratio of the measured number of IP data packets received by the digital receiver and a number of IP data packets that should have been received by the digital receiver; and
a display device to display a service level diagnostic indicator based upon the loss of IP data packets from the IP based data test stream to indicate the service level of the digital television broadcast signal, the service level diagnostic indicator being updated at predetermined intervals.

Abstract
The present invention provides a method, apparatus, and system for determining and displaying the service level of a digital television broadcast signal. A digital television receiver receives a digital television broadcast signal. The digital television broadcast signal includes a data test stream composed of a plurality of data packets. A service level determiner is used to determine a service level of the digital television broadcast signal based upon a loss of data packets from the data test stream (i.e. the error rate). The service level determiner additionally causes a representation of the service level to be displayed as a service level diagnostic indicator on a display device, such as a television. The service level diagnostic indicator can be updated at predetermined intervals to allow a user to place their antenna in a best service level position to receive the best service level as indicated by the service level diagnostic indicator.

7. A method comprising:
-
receiving a digital television broadcast signal that includes an Internet Protocol (IP) based data test stream located on a Packet Identifier (PID) of the digital television broadcast signal having a plurality of sequentially numbered IP data packets used to determine a service level of the digital television broadcast signal being received on a channel; determining the service level of the digital television broadcast signal based upon a loss of IP data packets from the IP based data test stream wherein determining the service level includes measuring a number of IP data packets of the IP based data test stream received over a predetermined interval and determining a data packet loss percentage value for the IP based data test stream by calculating a ratio of the measured number of IP data packets received and a number of IP data packets that should have been received; and displaying a service level diagnostic indicator based upon the loss of IP data packets from the IP based data test stream to indicate the service level of the digital television broadcast signal, the service level diagnostic indicator being updated at predetermined intervals. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computer-readable medium encoded with computer executable instructions being executed by a computer to perform:
-
receiving a digital television broadcast signal that includes an Internet Protocol (IP) based data test stream located on a Packet Identifier (PID) of the digital television broadcast signal having a plurality of sequentially numbered IP data packets used to determine a service level of the digital television broadcast signal being received on a channel; determining the service level of the digital television broadcast signal based upon a loss of IP data packets from the IP based data test stream wherein determining the service level includes measuring a number of IP data packets of the IP based data test stream received over a predetermined interval and determining a data packet loss percentage value for the IP based data test stream by calculating a ratio of the measured number of IP data packets received and a number of IP data packets that should have been received; and displaying a service level diagnostic indicator based upon the loss of IP data packets from the IP based data test stream to indicate the service level of the digital television broadcast signal, the service level diagnostic indicator being updated at predetermined intervals. - View Dependent Claims (14, 15, 16, 17, 18)
