Abstract: An example device for transporting media data includes: a memory configured to store media data; and one or more processors implemented in circuitry and configured to: determine that a manifest file for a media presentation includes data representing a delta time value for a resynchronization element of a segment of the media presentation; determine a multiple of the delta time value; determine a number of chunks of the segment that are currently available for retrieval using the multiple of the delta time value; send a request to a server device for the chunks of the segment that are currently available, wherein the request omits chunks of the segment that are not currently available; and store data of chunks received in response to the request in the memory.

Abstract: Devices and methods are disclosed that receive a request from a client device for a media file, determine compatibility of the media file with the requesting client device, and, if appropriate, transcode the media file into a compatible form which is then transmitted to the requesting client device. To determine whether a media file is compatible with the client request, the storage device can analyze a portion of the requested media file and compare that information with parameters of the client request. Transcoded data can be stored alongside the original file as a new file, stored in place of the original file, or stored in the same container as the original file so that the new file includes both the original version and the transcoded version of the media file.

Abstract: Systems, devices and automated process allow automatic replacement of advertisements or other content in previously-broadcast television programs. A content management system or the like operating on a digital network receives indicia from playback devices that have encountered identified advertisements that are stored in digital video recorders or that are otherwise contained within previously-broadcast television programs. The encounters are recorded in a database for subsequent analysis. If desired, the previously-broadcast advertisements may be replaced with more relevant or engaging advertisements prior to playback to the viewer, thereby allowing a fresher, more relevant and more engaging experience for the viewer.
