A usage data aggregator retrieves usage log data from each passenger terminal device of the vehicle entertainment system. A load set generator builds a ranked media content data set based upon prioritization scores assigned to each of the media content data items with adaptive inferences from the usage log data. The prioritization scores are correlated with trip factors established for a subsequent vehicle trip for which the ranked media content data set is being built. A content retriever transfers the one or more media content data items specified in the ranked media content data from the media content repository. ## Claims ### Claim 1 A system for managing media content data sets loaded onto a content server of a vehicle entertainment system presenting media content data items to passenger terminal devices, the system comprising: a media content repository storing one or more media content data items; a usage data aggregator in communication with the vehicle entertainment system to retrieve usage log data from each of the passenger terminal devices connected to the vehicle entertainment system; a load set generator receptive to the usage log data to build a ranked media content data set based upon prioritization scores assigned to each of the media content data items with adaptive inferences from the usage log data, at least one of the prioritization scores being correlated with one or more trip factors established for a subsequent vehicle trip for which the ranked media content data set is being built; and a content retriever in communication with the media content repository to transfer the one or more media content data items specified in the ranked media content data set. ### Claim 2 (depends on 1) The system of claim 1, wherein the number of media content data items in the ranked media content data set is less than an entirety of the media content data items stored in the media content repository. ### Claim 3 (depends on 1) The system of claim 1, wherein the media content data item is a single unit of programming presentable on the passenger terminal devices. ### Claim 4 (depends on 1) The system of claim 1, wherein the ranked media content data set is generated based upon a function of available bandwidth for the transfer of the one or more media content data items to the content server. ### Claim 5 (depends on 1) The system of claim 1, wherein the usage log data includes data points selected from a group consisting of: a frequency of viewing a given one of the one or more media content data items, a quantity of viewing the one or more media content data items, a quantity of viewing categories of the one or more media content data items, a duration viewed of the given one of the one or more media content data items, a time viewed of the given one of the one or more media content data items, an identity of a passenger viewing the given one of the one or more media content data items, and demographic information of the passenger viewing the given one of the or more media content data items. ### Claim 6 (depends on 1) The system of claim 1, further comprising a threshold controller receptive to adjustment inputs applied to the adaptive inferences in the assignment of the prioritization score, the generated ranked media content data set being modified according to the adjustment inputs. ### Claim 7 (depends on 6) The system of claim 6, wherein the adjustment inputs include modifying the number of media content data items in the ranked media content data set. ### Claim 8 (depends on 1) The system of claim 1, wherein the content retriever stores the transferred one or more media content data items to a portable content loader device connectible to the content server of the vehicle entertainment system. ### Claim 9 A media content manager for selectively loading media content data sets to an in-flight entertainment system, the media content manager comprising: a ground server receiving viewing preference and habit data from passenger terminal devices connected to the in-flight entertainment system, the ground server building a ranked media content data set based upon prioritization scores assigned to individual media content data items in the ranked media content data set with adaptive inferences from the viewing preference and habit data, the prioritization scores being correlated with one or more trip factors established for a subsequent flight for which the ranked media content data set is being built; and a content loader interface connectible to the ground server and a portable content loader device, the media content data items in the ranked media content data set being loaded on to the portable content loader device though the content loader interface. ### Claim 10 (depends on 9) The media content manager of claim 9, wherein the ground server includes a media content repository storing the media content data items. ### Claim 11 (depends on 10) The media content manager of claim 10, wherein the number of media content data items in the ranked media content data set is less than an entirety of the media content data items stored in the media content repository. ### Claim 12 (depends on 9) The media content manager of claim 9, wherein the media content data item is a single unit of programming presentable on the passenger terminal devices. ### Claim 13 (depends on 9) The media content manager of claim 9, wherein the ground server includes a threshold controller receptive to adjustment inputs applied to the adaptive inferences in the assignment of the prioritization score, the generated ranked media content data set being modified according to the adjustment inputs. ### Claim 14 (depends on 13) The media content manager of claim 13, wherein the adjustment inputs include modifying the number of media content data items in the ranked media content data set. ### Claim 15 (depends on 9) The media content manager of claim 9, wherein the viewing preference and habit data includes data points selected from a group consisting of: a frequency of viewing a given one of the one or more media content data items, a quantity of viewing the one or more media content data items, a quantity of viewing categories of the one or more media content data items, a duration viewed of the given one of the one or more media content data items, a time viewed of the given one of the one or more media content data items, an identity of a passenger viewing the given one of the one or more media content data items, and demographic information of the passenger viewing the given one of the or more media content data items. ### Claim 16 A method for selectively loading media content data sets onto a vehicle entertainment system content server that presents media content items to passenger terminal devices, the method comprising: receiving, on a ground server, viewing preference and habit data from the passenger terminal devices connected to the vehicle entertainment system, the viewing preference and habit data being recorded by the passenger terminal devices during at least one prior trip; receiving, on the ground server, one or more trip factors established for a subsequent trip; assigning prioritization scores to each media content item based upon adaptive inferences from the viewing preference and habit data, the prioritization scores being correlated with the one or more trip factors; building a ranked media content data set based upon the assigned prioritization scores of each of the media content items; and transferring the media content items in the ranked media content data set to the vehicle entertainment system content server. ### Claim 17 (depends on 16) The method of claim 16, further comprising: receiving an adjustment input; and applying a modification to the adaptive inferences in the assigning of the prioritization score to each media content item, the generated ranked media content data set being modified in response. ### Claim 18 (depends on 17) The method of claim 17, wherein the adjustment inputs include modifying the number of media content data items in the ranked media content data set. ### Claim 19 (depends on 16) The method of claim 16, further comprising: retrieving the media content data items in the ranked media content data set from a media content repository in communication with the ground server. ### Claim 20 (depends on 19) The method of claim 19 wherein the number of media content data items in the ranked media content data set is less than an entirety of the media content data items stored in the media content repository.
