20090013174 | METHODS AND SYSTEMS FOR HANDLING DIGITAL RIGHTS MANAGEMENT - 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. | 01-08-2009 |
20100107204 | DYNAMIC IPTV GROUP PROFILE CREATION AND MANAGEMENT - 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. | 04-29-2010 |
20100199341 | Methods, Subscriber Server, and User Equipment for Facilitating Service Provision - 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 2 | 08-05-2010 |
20100235875 | IPTV Devices and Methods Adapted for Such Devices - 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. | 09-16-2010 |
20100262831 | Method and Apparatus for Providing Secure Linking to a User Identity in a Digital Rights Management System - 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 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. A derived key is determined from the key received from the trusted key management server based at least on the device identifier and the random number. A challenge/response scheme is used to determine whether the derived key of the DRM server matches a derived key of the DRM device. | 10-14-2010 |
20110072477 | USING MOBILE TERMINALS FOR TEXT ENTRY IN IPTV CHAT SESSIONS - 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. | 03-24-2011 |
20110138432 | Media Bookmarks - 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). | 06-09-2011 |
20150143403 | IPTV DEVICES AND METHODS ADAPTED FOR SUCH DEVICES - 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. | 05-21-2015 |
