Description

This disclosure relates to the evaluation of the quality of linear media channel experiences, and more specifically, to a system and method for evaluating the quality of linear media channel experiences for mobile platforms, including aircraft. This specification describes systems, devices, and methods for monitoring data and/or managing data transmission on a mobile platform, including a vehicle. In one embodiment, a communication system is described comprising an in-flight server located inside a mobile platform and a remote server located outside the mobile platform. The remote server is configured to generate one or more linear media channels for use by the in-flight server. The communication system further comprises a virtual media client located inside the mobile platform. The virtual media client is configured to receive linear media channels from the in-flight server and transmit performance data to the in-flight server. The in-flight server is configured to receive one or more media requests from multiple user media clients inside the mobile platform. One or more media requests specify one or more linear media channels. The in-flight server is further configured to receive one or more linear media channels from the remote server, provide one or more linear media channels to multiple user media clients in accordance with the received media requests, provide at least a first linear media channel from the one or more media channels to the virtual media client, and receive a first set of performance data associated with the first linear media channel from the virtual media client. For the purpose of summarizing this disclosure, specific aspects, advantages, and novel features are described herein. It should be understood that not all such advantages may necessarily be achieved according to any particular embodiment. Therefore, the disclosed embodiments may be implemented in a manner that achieves or optimizes any advantage or group of advantages taught herein without necessarily achieving other advantages that may be taught or suggested herein. Various embodiments are shown in the accompanying drawings for illustrative purposes and should not be construed as limiting the scope of this disclosure. In addition, various features of the different embodiments disclosed can be combined to form additional embodiments that are part of this disclosure. This document describes a system for managing data transmission between a server on a mobile platform, such as a vehicle, and/or a server on a mobile platform, and a ground server, according to one or more embodiments. This shows a ground server according to one or more embodiments. This document shows an in-flight monitoring system according to one or more embodiments. This invention illustrates a process for evaluating the in-flight and/or ground performance of communication services provided on board a mobile platform, according to embodiments of this disclosure. The headings provided herein are for convenience only and do not necessarily affect the scope or meaning of the claimed invention. In certain implementations, this disclosure relates to systems, devices, and methods for managing and/or transferring system log data related to passenger services (e.g., provided on board a mobile platform) to and from an in-flight monitoring system of a mobile platform. Summary This disclosure provides devices, systems, and processes for evaluating quality of experience data for communication systems configured to deliver linear media channels and/or other media data to media clients on board a mobile platform (e.g., a vehicle). "Quality of experience" data can refer to any data representing a measure of communication service performance relating to the quality of user experience of one or more linear media channels, and may include, for example, startup data and/or rebuffer data. Startup data may include any data indicating the amount of time required for a media client to begin streaming media data. Rebuffer data may include any data indicating the number of rebuffer events in a media client during streaming of media data (rebuffer count) and/or the total time of rebuffer events (rebuffering duration). Rebuffer events may include interruptions in streaming media data to perform buffering operations and may occur at any point in time during streaming of media data as needed. In some cases, rebuffer events may be caused by failed and/or slow transmissions of media data between devices. A "linear media channel" can refer to any real-time broadcast of video and/or audio content, including, for example, live television content. A linear media channel can also include a scheduled content stream. In response to a user selecting a linear media channel, the user (i.e., their media client) can be invited to join the linear media channel and view the stream of content currently being provided by the linear media channel. For example, a content stream can be streamed simultaneousl
