Automatic Content Recognition (ACR) Fingerprinting And Video Encoding

Abstract:

A processing device and method are disclosed to generate automatic content recognition (ACR) fingerprints. A device can include a processing device to execute a capture daemon. The capture daemon may include a capturer to receive media content from a content feed and to generate content frames of the media content. The capture daemon can also include ACR fingerprinter to generate ACR fingerprint information for the content frames. The ACR fingerprinter may communicate the ACR fingerprint information to an ACR server via a first communication channel. The processing device may determine when the ACR fingerprinter fails; cease communicating the ACR fingerprint information to the ACR server; and restart the ACR fingerprinter.
