Abstract

In one embodiment, a method for performing testing of a receiver is provided. The method may include recording performance data associated with a radio signal received by a receiver, and recording global positioning system (GPS) data, where the GPS data is obtained from a GPS receiver co-located with the receiver. Then this data may be processed to map the performance data with the GPS data to indicate at least a location of the receiver and a corresponding receiver performance metric.

Claims

1. A method comprising:

recording performance data in a system, the performance data associated with a radio signal received by a broadcast receiver coupled to the system;

recording global positioning system (GPS) data in the system, the GPS data obtained from a GPS receiver co-located with the broadcast receiver; and

processing the performance data and the GPS data to map the performance data with the GPS data to indicate at least a location of the broadcast receiver and a corresponding receiver performance metric.

2. The method of claim 1, further comprising recording the radio signal in a recorder of the system.

3. The method of claim 1, wherein the processing includes formatting the performance data and the GPS data to generate information having a format compatible with a display application.

4. The method of claim 3, further comprising displaying the information on a display associated with the system using the display application, wherein the displaying includes providing a map view of an area in which the broadcast receiver was traveling and indicators to identify locations within the area at which the performance data was recorded.

5. The method of claim 4, wherein each of the indicators is selectable to display at least a portion of the performance data recorded at the corresponding location and to synchronize a playback of an audio signal obtained from the radio signal at the corresponding location.

6. The method of claim 5, further comprising displaying a table including at least the portion of the performance data as an overlay to at least part of the map view.

7. The method of claim 6, further comprising displaying a table including textual information obtained from demodulated data received by the broadcast receiver and further including at least one performance metric associated with the demodulated data.

8. The method of claim 1, wherein the performance data includes a signal strength of the radio signal and a signal-to-noise ratio of the radio signal, and the GPS data includes a location of the GPS receiver, and a heading at which the GPS receiver was traveling.

9. The method of claim 1, further comprising recording the performance data for a first broadcast receiver and a second broadcast receiver, and displaying at least a portion of the performance data for the first and second broadcast receivers on a display of the system, wherein the first and second broadcast receivers are of different manufacturers or include different firmware.

10. A system comprising:

a receiver to receive a radio frequency (RF) signal and to convert the RF signal into a demodulated signal and to generate performance data regarding the RF signal;

a global positioning system (GPS) receiver to receive a GPS signal and to generate GPS data therefrom; and

a computer system coupled to the receiver and the GPS receiver to receive the performance data and the GPS data obtained during traversal of a route on which the receiver and the GPS receiver travel and to process the performance data and the GPS data to map the performance data with the GPS data to indicate at least a location of the receiver and a corresponding receiver performance metric.

11. The system of claim 10, wherein the computer system is to record the demodulated signal.

12. The system of claim 10, further comprising a test equipment coupled to a calibrated antenna to receive the RF signal, wherein the test equipment is to generate at least one signal performance metric based on the RF signal.

13. The system of claim 10, further comprising a file generator to generate a file including a plurality of entries each including the GPS data and the performance data for a data acquisition point along the route.

14. The system of claim 13, wherein the computer system includes a mapping application to cause a display of the route and selectable markers along the route each corresponding to a data acquisition point.

15. The system of claim 14, wherein the mapping application is to display at least a portion of the performance data recorded at the data acquisition point in a table included as an overlay to at least part of the route display, and to enable synchronized playback of recorded audio data obtained from the receiver for the data acquisition point.

16. The system of claim 10, further comprising a second receiver coupled to the computer system to receive the RF signal, the second receiver configured differently from the first receiver and to convert the RF signal into a second demodulated signal and to generate performance data regarding the RF signal, and wherein the computer system is to receive and process the second receiver performance data and to associate the second receiver performance data with the performance data and the GPS data.

17. A system comprising:

a processor to execute instructions;

a storage medium including instructions that enable the system to receive performance data associated with a radio frequency (RF) signal received in a receiver coupled to the system and global positioning system (GPS) data received in a GPS receiver coupled to the system for traversal of a route on which the receiver and the GPS receiver travel, associate the performance data with the GPS data, generate a file including a plurality of entries each including the GPS data and the performance data for a data acquisition point along the route, and enable display of the route and selectable markers along the route, each of the selectable markers corresponding to a data acquisition point; and

a display to display the route and the selectable markers.

18. The system of claim 17, wherein the system includes an audio recorder to record an audio signal received from the receiver, the audio signal generated in the receiver from the RF signal, wherein playback of the audio signal is to be synchronized with regard to the data acquisition points.

19. The system of claim 17, further comprising instructions to enable the system to format the performance data and the GPS data to generate the file having a format compatible with a display application, and display the file on the display, wherein the display of the route includes a map view of an area in which the receiver was traveling.

20. The system of claim 17, further comprising a test equipment coupled to a calibrated antenna to receive the RF signal, wherein the test equipment is to generate at least one signal performance metric based on the RF signal and to provide the signal performance metric to the system for association with the performance data.
