Abstract: The disclosed computer-implemented method may include generating a table for a plurality of encodings of media files stored in at least one data center, the generating including determining a benefit to cost ratio for each encoding listed in the table based on one or more criteria associated with the respective encoding, and assigning a priority to each of the encodings in the table based on the benefit to cost ratio, determining whether a soft quota for an amount of memory for storage of the media files has been exceeded, and in response to determining that a soft quota for an amount of memory for storage of the media files has been exceeded, performing a data storage reduction process based on the priority associated with each of the encodings in the table. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Described herein are techniques that may be used to identify a portion of media data to be prioritized. Such techniques may comprise receiving, from a media collection device, media information that includes a first media data and at least one of trigger data or sensor data, determining, based on one or more of the trigger data or the sensor data, that a portion of the first media data is to be prioritized, identifying, based on one or more of the trigger data or the sensor data, a beginning and end time to be associated with a second media data that includes the portion of the first media data, and generating the second media data from the received first media data based on the beginning and ending time, the second media data including less than the entirety of the first media data.

Abstract: A method is described in which media content provided by a remote presenter is presented on a local device in a graphical user interface other than a graphical user interface provided by the remote presenter; an occurrence of a triggering event associated with the media content at a point in time is detected on the local device; a first portion of the media content preceding the point in time for a first duration of time and a second portion of the media content following the point in time for a second duration of time is stored on the local device responsive to detecting the occurrence of the triggering event; and an association between the triggering event and the stored first and second portions of the media content is stored on the local device.
