Back-end content analysis system to initiate second-screen confirmation

A method for confirming presence of a second-screen device with regard to a first-screen device, the method comprising:

• receiving, by the second-screen device via a second network, a trigger event from a back-end system comprising one or more computer servers coupled to a content delivery network of a content delivery system;
• the back-end system receiving a content from a server of a tuner server farm, the tuner server farm comprising a plurality of tuner servers coupled to the content delivery network,
• wherein each tuner server comprises a plurality of channel tuners, each channel tuner able to tune to a selected channel of a plurality of different channels of the content delivery system,
• wherein the received content is being delivered by the content delivery system to the first-screen device, and
• wherein the back-end system is at a remote physical location separate from both the first-screen device and the second-screen device, and further wherein the plurality of tuner servers are each at a different physical location from either the first-screen device or the second-screen device;
• the back-end system performing a first content detection analysis of the content to determine the trigger event, wherein multiple fingerprints are generated from multiple portions of the content and the trigger event is generated in response to comparing the multiple fingerprints to a fingerprint index and when a match between a first fingerprint in the multiple fingerprints and a second fingerprint in the fingerprint index occurs;
• based on receiving the trigger event, initiating, by the second-screen device, access of a hardware element to detect information within a range of the second-screen device;
• determining, by the second-screen device, whether the second-screen device is in a same location as the first-screen device using a second content detection analysis of the information detected by the hardware element;
• and
• sending, by the second-screen device, a presence confirmation that the second-screen device is in the same location of the first-screen device when the second content detection analysis detects the content from the content delivery system is being output by the first-screen device.

A system comprising:

• a first-screen device configured to request delivery of content from a content delivery system via a content delivery network;
• a second-screen device associated with a user of the first-screen device;
• and
• a back-end system integrated with the content delivery system, the back-end system comprising one or more computers at a physical location remote from both the first-screen device and the second-screen device, the one or more computers configured to perform:
• receiving the content from a server of a tuner server farm, the tuner server farm comprising a plurality of tuner servers coupled to the content delivery network, wherein the plurality of tuner servers are each at a different physical location from either the first-screen device or the second-screen device, wherein each tuner server comprises a plurality of channel tuners, each channel tuner able to tune to a selected channel of a plurality of different channels of the content delivery system, and wherein the received content is being delivered by the content delivery system via the content delivery network to the first-screen device;
• performing a content detection analysis of the content;
• determining a trigger event based on the content detection analysis, the trigger event being triggered based on detecting the trigger event in a portion of the content, wherein multiple fingerprints are generated from multiple portions of the content and the trigger event is generated in response to comparing the multiple fingerprints to a fingerprint index and when a match between a first fingerprint in the multiple fingerprints and a second fingerprint in the fingerprint index occurs;
• and
• communicating the trigger event, via a second network, to the second-screen device for the user, the trigger event causing the second-screen device to start a presence detection analysis using hardware of the second-screen device to confirm the second-screen device's presence with regard to the first-screen device.
