Abstract: The present invention relates to a method for the synchronization of the playback of an audio file with the playback of a related video file, and particularly to the method for synchronizing a video and an audio file being simultaneously reproduced by a video client player and an audio client player, respectively, by means of computing an audio playback position with video playback position signals and timestamp signals received from the video client player and a server hosting a web application.

Abstract: A method for web access control that comprises the following steps: creating a content item (1) in a content management system; generating a series of unique secure random access tokens (2) and storing them in a database (3); generating a file containing the ATs with their corresponding direct link URLs, when a client device accesses the content using a browser (11), checking with the server if the request's BID is already registered for this AT; if it is already registered, allowing access to the content; if not, checking if a preset limit of allowed registered BIDs for the AT has been reached; if the limit has been reached, denying access to the content; if not, registering the new BID with the AT and allowing access to the content.
