Abstract: A media client ascertains a plurality of matching points between (i) query fingerprints representing a media stream being received by the client and (ii) reference fingerprints, each identified matching point defining a respective match between a query fingerprint that is timestamped with client time defined according to a clock of the client and a reference fingerprint that is timestamped with true time defined according to a timeline within a known media stream. Further, the client performs linear regression based on the timestamps of the ascertained plurality of matching points, to establish a mapping between true time and client time. The client then uses the established mapping as a basis to determine a client-time point at which the client should perform an action with respect to media stream being received by the client. And the client performs the action at the determined client-time point.

Abstract: In one aspect, an example method includes (i) identifying, by a playback device, a media device based on a control message received from the media device by way of an audio and/or video interface, where the media device provides media content to the playback device; (ii) providing, by the playback device, replacement media content for display; (iii) determining, by the playback device, that while the playback device is displaying the replacement media content a remote control transmitted an instruction to the identified media device; (iv) determining, by the playback device, a playback-modification action corresponding to the instruction and the identified media device; and (v) modifying, by the playback device, playback of the replacement media content in accordance with the playback-modification action.

Abstract: When a media client is receiving a media stream, the media client determines an upcoming time point at which the media client is to perform a content revision involving insertion (e.g., substitution or overlaying) of new content. The media client further determines an advanced time point when the media client should initiate a process of acquiring the new content, setting the advanced time point sufficiently in advance of the upcoming content-revision time point to enable the media client to obtain at least enough of the new content to be able to start the content revision on time. In an example implementation, the media client could determine the advanced time point by predicting how long the content-acquisition process will take, based on consideration of past instances of content acquisition, possibly correlated with operational factors such as content source, processor load, memory load, network speed, and time of day.

Abstract: A client device accesses a video input stream from an intermediate device for display. The client device analyzes the video input stream to determine that the video input stream matches a template corresponding to a screen portion. Based on the video input stream matching the template, a video output stream is generated and caused to be presented on a display. In some example embodiments, the analysis is performed while the client device is replacing video content received from a content source via the intermediate device. For example, commercials transmitted from a national content provider to a smart TV via a set-top box may be replaced with targeted commercials. During the replacement, menus generated by the set-top box may be detected and the replacement video altered by the smart TV to include the menus.

Abstract: Methods and systems to authorize devices and/or perform other actions based on identifying content distributors are described. In some example embodiments, the methods and systems access video content playing at a client device, calculate fingerprints of a portion of the video content, identify a distributor of the video content based on the fingerprints, and perform an action in response to the identification of the distributor of the video content, such as actions to authorize the client device or other associated devices (e.g., second screens) to receive content from the distributor, actions to present sponsored content to the client device or associated devices, and so on.

Abstract: A computing system identifies a media stream being received by a client, based on fingerprint matching conducted with query fingerprints generated by the client at a frame rate. The computing system then causes the client to increase the frame rate, in order to facilitate establishment by the computing system of synchronous lock between true time within the media stream and client time according to a clock of the client. The computing system then uses the established synchronous lock as a basis to map a true-time point at which a content revision should be performed in the media stream to a client-time point at which the client should perform the content revision. And the computing system causes the client to perform the content revision at the determined client-time point.

Abstract: In one aspect, an example method includes (i) providing, by a playback device, replacement media content for display; (ii) determining, by the playback device, that a remote control transmitted to the playback device an instruction configured to cause a modification to operation of the playback device while the playback device displays the replacement media content; (iii) determining, by the playback device based on the instruction, an overlay that the playback device is configured to provide for display in conjunction with the modification; (iv) determining, by the playback device, a region within a display of the playback device corresponding to the overlay; and (v) modifying, by the playback device, a transparency of the region such that the overlay is visible through the replacement media content when the playback device provides the overlay for display.
