Multilayered document distribution in multiscreen systems

摘要

An educational digital publication platform coordinates distribution of multilayered content documents to multiple devices of a user. The platform ingests content and transforms it into a form suitable for web-based publication in the form of a multilayered document while preserving page fidelity. EReading browser applications executing on user devices render layers of the multilayered content into a form readable by end users. The publishing platform authenticates or denies requests to access content on each device and manages distribution of the content to the browser applications executing on authenticated devices, thereby effectively connecting multiple devices of the same user. As the end user interacts with the content, activities are logged by the platform and reported to all the user's connected devices in order to synchronize delivery of content and services.

1. A method for coordinating distribution of a multilayered document to eReading applications executing on a plurality of a user's devices, the method comprising:
accessing the multilayered document at an eReading platform, the multilayered document comprising a core layer and one or more additional layers, wherein the core layer comprises one or more pages of a publication, and wherein the one or more additional layers comprise supplemental content associated with the pages, the core layer and the one or more additional layers stored at a plurality of locations associated with the eReading platform; generating at the eReading platform, an access code for unlocking access to the multilayered document; sending, by the eReading platform the generated access code to a plurality of devices of a user for storage by the plurality of devices; receiving, by the eReading platform the access code from a first device of the plurality of devices and from a second device of the plurality of devices of the user; responsive to receiving the access code from the first device and the second device,
sending, to the first device and the second device from the eReading platform, a set of time-sensitive uniform resource locators (URLs) referencing the plurality of locations, the time-based URLs referencing the plurality of locations prior to a time of expiry and not referencing the plurality of locations after the time of expiry;responsive to the first device accessing one or more of the plurality of locations using the time-sensitive URLs, distributing to the first device at least a first layer of the multilayered document for rendering during a first authenticated session of a first eReading browser application executing on the first device, wherein the at least first layer of the multilayered document distributed to the first device comprises a first set of layers;responsive to the second device accessing one or more of the plurality of locations using the time-sensitive URLs, distributing to the second device at least a second layer of the multilayered document for rendering during a second authenticated session of a second eReading browser application executing on the second device, wherein the at least second layer of the multilayered document comprises a second set of layers, wherein the first set of layers is not identical to the second set of layers, and wherein the first session overlaps in time with the second session;receiving at the eReading platform, a change made to the second layer at the second device;storing the received change at one of the plurality of locations; anddynamically sending the received change of the second layer to the first device to provide a synchronized service to the user.
