USApp 2004/0141713 A1 disclosing a service provider personal video recorder employing a remote data storage and USApp 2004/0259537 A1 disclosing a cell phone multimedia controller and USApp 2003/0095791 A1 disclosing a system and method for internet access to a personal television service disclose technologies common in the art that may be used for realizing the invention.
By applying an application that provides location based services, i.e. a service to detect when the subscriber is away from his home (zone), and hence is unable to invoke any recording function as he is away from his set top box, the network is able to offer an innovative service. Through detection that the subscriber is away from his set top box and that there is dynamic content about to be broadcasted that matches his personal preferences (which was not able to be foreseen through normal programming schedules), the subscriber may be notified through for example Instant Messaging. The subscriber is now enabled to choose whether he wants to invoke the network personal video recorder functionality, and can do this through various means such as SMS or HTTP for example from his mobile terminal. This service allows the subscriber to record content he would otherwise have missed, as well as provides a means to recuperate otherwise lost revenue for the service provider.
A scenario may be as follows: The subscriber sets up his preferences via a set top box. The personal service environment links up with content metadata of the video server to be able to trigger upon the subscriber's preferences. The subscriber moves away from his set top box, and this is detected by the location service. The personal service environment is notified that the subscriber is away from home. When dynamic content according to the subscriber's profile is available to be streamed, the personal service environment is notified. The personal service environment notifies the subscriber as to the availability of preferred content. The subscriber opts to record the content. The network personal video recorder is started. Content is streamed and recorded by the network personal video recorder. The subscriber, at a later stage when he is back at home, watches the recorded content.
This solution offers the subscriber the opportunity to record more content, and to thereby generate more revenue for the service providers. It may also be a differentiator for a triple play offer. This solution lets the subscriber record content that is being broadcast at a time when he is not able to normally invoke the recording functionality.
In the Figures, each coupling/connection may be a wired coupling/connection or a wireless coupling/connection. Any unit shown may be divided into sub-units, and any two or more units may be integrated into a new and larger unit. Any unit shown may comprise hardware and/or software. The computer program product according to the invention may be stored on and/or comprise a fixed medium or a removable medium.
The expression “for” in for example “for controlling”, “for receiving”, “for storing” and “for detecting” etc. does not exclude that other functions are performed as well, simultaneously or not. The expressions “X coupled to Y” and “a coupling between X and Y” and “coupling/couples X and Y” etc. do not exclude that an element Z is in between X and Y. The expressions “P comprises Q” and “P comprising Q” etc. do not exclude that an element R is comprised included as well. The terms “a” and “an” do not exclude a possible presence of one or more pluralities.
The steps and/or functions of “storing” and “detecting” do not exclude further steps and/or functions, like for example, inter alia, the steps and/or functions described for the Figures etc.
