METHODS AND APPARATUS TO DETECT SPILLOVER IN AN AUDIENCE MONITORING SYSTEM |
摘要 |
Methods and apparatus to detect spillover in an audience monitoring system are disclosed. An example method includes sampling a first audio signal from a first source received by a first microphone; sampling a second audio signal received by a second microphone from the first source, wherein the second microphone is separated from the first microphone by a first distance; calculating an origin direction of the first source based on a time difference between receipt of the first and second audio signals; when the origin direction is within a threshold angle, retaining the media associated with the first source; and when the origin direction exceeds the threshold angle, ignoring the media associated with the first source |

1. A method to distinguish local media from spillover media content comprising:
sampling a first audio signal from a first source received by a first microphone; sampling a second audio signal received by a second microphone from the first source, wherein the second microphone is separated from the first microphone by a first distance; calculating an origin direction of the first source based on a time difference between receipt of the first and second audio signals; when the origin direction is within a threshold angle, retaining the media associated with the first source; and when the origin direction exceeds the threshold angle, ignoring the media associated with the first source. |
