Abstract: Methods and apparatus for enabling upgrading of a television (TV) device that is connectable to an internet protocol TV (IPTV) system including an operator system and a TV manufacturer system are described. The upgrading is based on a token object and verifies a requested upgrading of the TV device. A token object is generated at the TV manufacturer system in response to receiving a request for upgrading from the TV device, and delivered to the TV device, thus enabling the TV device to complete the requested upgrading process due to possessing a valid token. A TV device, an operator system, and a TV manufacturer system adapted to execute the suggested methods are also provided.

Abstract: A system and method for signaling timing and content of personalized ads to a hybrid terminal via a television broadcast/multicast network. The currently-present ad insertion markers in the transport stream of the broadcast/multicast content are replaced by a Service Information, SI, table that contains information corresponding to the replaced markers. The table-containing transport stream is then delivered to the hybrid terminal. The SI table may include a manifest to signal upcoming time slots for advertising. The manifest may provide information about sources from which the hybrid terminal can fetch personalized advertisements and may also identify available time slots in the transport stream for inserting the fetched ads. To enable the hybrid terminal to present personalized advertisements to its viewer, the SI table may identify an Ad Decision Server, ADS, from which the hybrid terminal can request targeted ads for playback to the viewer watching a broadcast/multicast TV program.

Abstract: A system and method that enables a user to interact with an advertisement and express an opinion about it. Such user interactivity is provided through a Hybrid Broadcast Broadband TV, HbbTV, auto-start application, which is associated with an advertisement event and a Uniform Resource Locator, URL, to the auto-start application is carried in a Digital Video Broadcast Application Information Table, DVB AIT, of the broadcast transport stream associated with the TV program or channel where the advertisement is to be shown. The hybrid terminal receiving the AIT-containing transport stream retrieves the auto-start application using the URL before the corresponding ad is played back to the viewer. When the ad is played, the retrieved application is simultaneously launched. The application's UI allows the user to interact with the ad or express an opinion about the content of the ad. A user's interaction with an advertisement can be tracked as well.

Abstract: Disclosed is a DRM device and method for providing secure linking to a user identity. A first request is sent to a subscriber identity module. A message is received from the subscriber identity module via a secure authenticated channel. The message comprises at least a master key identifier, a random number, and a derived key. In response to the message, a second request is sent to a DRM server. The second request comprises at least a master key identifier, the device identifier, and a random number. Also disclosed is a DRM server and method for providing secure linking to a user identity. A first request is received from a DRM device. The first request comprises at least master key identifier, a device identifier, and a random number. The DRM device is authenticated. A second request for an application specific key is sent to a trusted key management server. The second request comprises at least a master key identifier. At least a key is received from the trusted key management server.

Abstract: An IPTV group profile is dynamically generated based on individual IPTV user profiles, whenever a user joins or leaves a shared IPTV session at an IPTV Terminal Function (ITF). The IPTV group profile may be implemented as a modification to the IPTV user profile of each user. In one embodiment, a “group” branch includes the additional access privileges and/or restrictions from the IPTV user profiles of other group members. The modified IPTV user profiles of users in the group are placed on a network entity such as an XDM Server (XDMS), to which the ITF subscribes via XCAP. As users join or leave a shared IPTV session at an ITF, the IPTV-AS updates the IPTV user profiles on the XDMS, which notifies the ITF of the changes. Each user's IPTV user profile at the ITF thus reflects group access privileges, preferences and restrictions for the duration of the shared IPTV session.

Abstract: Specific instances in time, e.g., scenes, in a program or other media content can be marked in an unambiguous manner. A scene's marking information, which can be called a bookmark, is preferably stored in communication network as a part of a user's service profile. With such a bookmark, a user can, among other things, resume watching a program from the bookmarked point onwards on the same or a different media device, and send the bookmark to others, e.g., as a link in chat or other social networking interactions, so that they can watch the program from or around the bookmarked scene (provided, of course, that they have rights to access that content).

Abstract: Systems and methods according to the exemplary embodiments provide for chat session handling in IPTV systems. A chat server can be configured to forward text messages associated with a particular chat session toward an IPTV terminal for output thereon. Chat message entry can be performed by using a wireless text entry device, e.g., a mobile phone. An IPTV control server can be configured to recognize a request for a chat session which involves output of chat messages on an IPTV terminal, and to verify that the user has a linked mobile phone and IPTV subscriptions.

Abstract: A User Equipment (UE), a Home Subscriber Server (HSS), and methods are provided for facilitating access to a second service (e.g. IPTV, IP Television) when the user registers with a network for a first service (e.g. IMS, IP Multimedia Subsystem service, or 2G mobile service). For example, the user employs his mobile terminal to register for IMS service, then requests a security token for the provision of the second service. The network validates the user subscription and provides the security token associated with the 2nd service, e.g. with IPTV. The user can input the security token for obtaining access to the 2nd service, e.g. from another terminal. For example, the user can input the token, e.g. in the form of a PIN code, on an ITF (IP Television Terminal Function) to be provided personalised IPTV service, or for performing IPTV parental control on his IPTV subscription involving multiple users.

Abstract: Systems and methods according to the present invention address this need and others by providing methods and systems for translating media encrypted by various Digital Rights Management (DRM) techniques. This allows end user equipment to receive media in an IMS/IPTV environment when the end user equipment uses a DRM that is different from the media server which is providing the desired media in both unicast and multicast applications.
