Abstract
A method and system for logo identification based on automatic content recognition (ACR) are described in which a connected television (TV) or other end-user device may be provided with instructions to fingerprint certain regions in a video frame to identify the source of the content being displayed. Such instructions may be provided when, for example, fingerprint matching is able to identify content that is provided by multiple sources but is unable to identify the particular source of the content. In those instances, one or more additional locations may be determined for taking fingerprints in the video frame. These locations correspond to region of the video frame in which a graphical item that represents the network television station is typically displayed. A profile with these locations is generated and sent to the connected TV to take additional fingerprints to enable the identification of the network television station providing content.
