METHOD AND SYSTEM FOR PRESENTING ADDITIONAL CONTENT AT A MEDIA SYSTEM
A media system, receives a received sequence of media content, for presentation at the media system and generates a comparison fingerprint of the received sequence of media content. The comparison fingerprint is for comparison with a plurality of reference fingerprints so as to identify the received sequence of media content. The media system sends a request for identification of additional content to a server system. The request is based at least in part on the comparison fingerprint. The media system receives a response to the request, including information enabling additional content to be selected for display at the media system based at least in part on the identification of the received sequence of media content, and presents a displayed sequence of media content that includes at least a portion of the received sequence of media content and at least a portion of the additional content.
1 . A method comprising:
receiving, by a computing system, media content generated for live broadcast to a client device;
generating, by the computing system, reference fingerprint data representing the received media content on-the-fly during a broadcast delay period bounded by a first time that the media content is generated for live broadcast and a second time that the media content is displayed by the client device;
during the broadcast delay period, the computing system storing the generated reference fingerprint data in association with information identifying the generated media content;
receiving, after the second time, query fingerprint data from the client device; and
determining, by the computing system, that the client device is displaying the live broadcast media content based on the received query fingerprint data matching the reference fingerprint data.
2 . The method of claim 1 , further comprising delaying, by the computing system, the live broadcast of media content for a time duration that is at least a portion of the broadcast delay period.
3 . The method of claim 2 , wherein the time duration is longer than a delay used solely for compensating for transmission rate variations or for censoring live content.
4 . The method of claim 1 , further comprising, responsive to determining that the client device is displaying the live broadcast media content, generating subsequent reference fingerprint data from a subsequent segment of the media content generated for live broadcast.
5 . The method of claim 4 , further comprising, responsive to determining that the client device is displaying the live broadcast media content, sending the generated subsequent reference fingerprint data to the client device within a broadcast delay period of the subsequent segment of the media content, such that the client device receives the generated subsequent reference fingerprint data prior to the client device displaying the subsequent segment of the media content.
6 . The method of claim 5 , further comprising receiving, from the client device, an indication that the client device is continuing to display the live broadcast media content based on a comparison between the subsequent reference fingerprint data and a comparison fingerprint representing media content received by the client device.
7 . The method of claim 1 , wherein storing the reference fingerprint data comprises, for one or more reference fingerprints of the reference fingerprint data, storing the reference fingerprint in association with data identifying a time stamp of the media content, a channel of the media content, or a time when a next advertisement begins.
8 . A non-transitory computer-readable storage medium having stored thereon program instructions that, when executed by one or more processors of a computing system, cause the computing system to perform operations comprising:
receiving media content generated for live broadcast to a client device;
generating reference fingerprint data representing the received media content on-the-fly during a broadcast delay period bounded by a first time that the media content is generated for live broadcast and a second time that the media content is displayed by the client device;
during the broadcast delay period, storing the generated reference fingerprint data in association with information identifying the generated media content;
receiving, after the second time, query fingerprint data from the client device; and
determining that the client device is displaying the live broadcast media content based on the received query fingerprint data matching the reference fingerprint data.
9 . The non-transitory computer-readable storage medium of claim 8 , the operations further comprising delaying the live broadcast of media content for a time duration that is at least a portion of the broadcast delay period.
10 . The non-transitory computer-readable storage medium of claim 9 , wherein the time duration is longer than a delay used solely for compensating for transmission rate variations or for censoring live content.
11 . The non-transitory computer-readable storage medium of claim 8 , the operations further comprising, responsive to determining that the client device is displaying the live broadcast media content, generating subsequent reference fingerprint data from a subsequent segment of the media content generated for live broadcast.
12 . The non-transitory computer-readable storage medium of claim 11 , the operations further comprising, responsive to determining that the client device is displaying the live broadcast media content, sending the generated subsequent reference fingerprint data to the client device within a broadcast delay period of the subsequent segment of the media content, such that the client device receives the generated subsequent reference fingerprint data prior to the client device displaying the subsequent segment of the media content.
13 . The non-transitory computer-readable storage medium of claim 12 , the operations further comprising receiving, from the client device, an indication that the client device is continuing to display the live broadcast media content based on a comparison between the subsequent reference fingerprint data and a comparison fingerprint representing media content received by the client device.
14 . The non-transitory computer-readable storage medium of claim 8 , wherein storing the reference fingerprint data comprises, for one or more reference fingerprints of the reference fingerprint data, storing the reference fingerprint in association with data identifying a time stamp of the media content, a channel of the media content, or a time when a next advertisement begins.
15 . A computing system comprising one or more processors and a non-transitory computer-readable storage medium having stored thereon program instructions that, when executed by the one or more processors, cause the computing system to perform operations comprising:
receiving media content generated for live broadcast to a client device;
generating reference fingerprint data representing the received media content on-the-fly during a broadcast delay period bounded by a first time that the media content is generated for live broadcast and a second time that the media content is displayed by the client device;
during the broadcast delay period, storing the generated reference fingerprint data in association with information identifying the generated media content;
receiving, after the second time, query fingerprint data from the client device; and
determining that the client device is displaying the live broadcast media content based on the received query fingerprint data matching the reference fingerprint data.
16 . The computing system of claim 15 , the operations further comprising delaying the live broadcast of media content for a time duration that is at least a portion of the broadcast delay period.
17 . The computing system of claim 16 , wherein the time duration is longer than a delay used solely for compensating for transmission rate variations or for censoring live content.
18 . The computing system of claim 15 , the operations further comprising, responsive to determining that the client device is displaying the live broadcast media content, (i) generating subsequent reference fingerprint data from a subsequent segment of the media content generated for live broadcast and (ii) sending the generated subsequent reference fingerprint data to the client device within a broadcast delay period of the subsequent segment of the media content, such that the client device receives the generated subsequent reference fingerprint data prior to the client device displaying the subsequent segment of the media content.
19 . The computing system of claim 18 , the operations further comprising receiving, from the client device, an indication that the client device is continuing to display the live broadcast media content based on a comparison between the subsequent reference fingerprint data and a comparison fingerprint representing media content received by the client device.
20 .
