Problems solved by technology

The existence of diverse communication channels for receiving TV programs makes it even more challenging to provide an efficient, accurate estimate of the viewership of a particular TV program at a large population level (e.g., at a country level)

Embodiment Construction

[0022] TV viewing in the domestic market can be quite fragmented. In some implementations, the TV viewing estimation system receives raw viewing data from multiple TV content providers (eg, cable and satellite companies, over-the-air broadcasters, and Internet streaming sites). The TV ratings estimation system aggregates raw data from each of the different content providers for different geo-demographic groups (i.e., a specific viewer's geo-demographic, geographic region, and / or some combination of both characteristics), And computing viewership share information for a particular group at a statistically significant level. For example, a TV viewing estimation system calculates shares per minute when sufficient data exists (e.g., in metropolitan areas) and shares per minute when there is not enough data to reliably determine shares per minute (e.g., in sparsely populated areas). , where there are few subscribers for a particular service / content provider) hourly shared informat...

Abstract

A computer-implemented method for clustering audio fingerprints from different set top boxes into groups based on their similarities is disclosed. The computer server receives audio fingerprints generated at different set top boxes and partitions them into multiple groups such that audio fingerprints within a group correspond to a respective TV program being played at the respective set top boxes. Upon receipt of an audio fingerprint from a set top box, the computer server identifies a group of audio fingerprints that are substantially similar to the audio fingerprint, determines TV program information for the audio fingerprint in accordance with the channel metadata associated with the identified group of audio fingerprints, and returns the TV program information to the requesting set top box.

Description

technical field [0001] The disclosed implementations relate generally to TV (television) broadcasting, and in particular to systems and methods for determining a program being broadcast at a television set through audio / visual signal recognition. Background technique [0002] Nowadays, people can obtain the same TV content from different suppliers through different communication channels such as satellite, cable, telephone line and Internet. The selection of a communication channel often has many geographic and demographic considerations. For example, a satellite receiver is probably the most common device for receiving TV signals in homes in rural areas. However, it may be more common for homes in metropolitan areas to receive TV signals using a cable connection or over the air (OTA) antenna. While many people still watch TV programming on TV, younger viewers may increasingly choose to watch TV programming on computers coupled to the Internet or even on smart phones that ...
