20200029059 | COLOR DISPLAY MODES FOR A THERMAL IMAGING SYSTEM - Systems and methods for allocating display colors to thermal image intensity data acquired by thermal band photodetectors are described. The intensity data from the photodetectors, which corresponds to the scene temperature, is usually converted to a digital value falling within the range of the analog to digital conversion (ADC). The full ADC range may be divided into two or more sub-ranges. In at least one sub-range intensity values within that sub-range may be assigned display colors from a first color table utilizing one or more Histogram Equalization (HE) techniques. In at least one other sub-range, specific display values from a color table different from the first may be assigned to specific intensity values. In some embodiments, the HE assigned sub-range may be lower in intensity than the specific assigned sub-range. For a thermal imaging system including thermography, the sub-ranges may correspond to scene temperature ranges, where lower temperatures are assigned colors using HE and higher temperatures are assigned specific colors corresponding to specific temperatures. Such an arrangement is particularly applicable to thermal imaging use by firefighters because the arrangement allows them to determine temperature directly from displayed color for potentially dangerous temperatures. In some cases the sub-range may be applied to certain pixels within desired temperature ranges, and those chosen pixels may be assigned to all or part of a second color table, and in some cases the second color table may be applied to the sub-range pixels by histogram equalization. This arrangement is applicable to highlighting temperatures corresponding to objects, such as humans or animals to make these objects high contrast for search applications. | 2020-01-23 |

The method includes: receiving a video stream from a video obtaining system, where the video stream includes a to-be-identified object; determining a compensation element for the to-be-identified object, where the compensation element is used to represent an element that needs to be adjusted for the to-be-identified object; sending the compensation element and a compensation parameter of the compensation element to the video obtaining system; and receiving an adjusted video stream sent by the video obtaining system, where the adjusted video stream is a video stream after the video obtaining system adjusts the compensation element for the to-be-identified object based on the compensation parameter. | 2020-01-23 |
20200029107 | Advanced Preparation for Content Revision Based on Expected Latency in Obtaining New Content - 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. | 2020-01-23 |
20200029108 | Establishment and Use of Time Mapping Based on Interpolation Using Low-Rate Fingerprinting, to Help Facilitate Frame-Accurate Content Revision - A computing system identifies multiple matching points between (i) query fingerprints representing a media stream being received by a client and (ii) reference fingerprints, each identified matching point defining a respective match between a query fingerprint timestamped with client time defined according to a clock of the client and a reference fingerprint timestamped with true time defined according to a timeline within a known media stream. Further, the computing system performs linear regression based on the timestamps of the matching points, to establish a mapping between true time and client time. The computing system then uses the mapping to determine a client-time point at which the client should perform a content revision or other action with respect to the media stream being received by the client. And the computing system causes the client to perform the content revision or other action at the determined client-time point. | 2020-01-23 |
20200029109 | MEDIA PLAYBACK CONTROL THAT CORRELATES EXPERIENCES OF MULTIPLE USERS - A system, method and program product for system for processing audio visual (AV) content items during playback. A system is disclosed that includes: a controller for selecting a content item and filtering the content item during playback based on filtering parameters; an audience identification system that identifies members of an audience intended to view the content item and obtains user attributes of each member of the audience; and a filtering manager that calculates the filtering parameters based on the user attributes and metadata tags associated with the content item, wherein the metadata tags are obtained from a remote metadata repository that generates metadata tags from feedback obtained from participating system users. | 2020-01-23 |
