20110064219 | IPTV SECURITY IN A COMMUNICATION NETWORK - A method of setting up a secure IPTV session. An Application Server (AS) receives an invite message from an IPTV receiving node such as a mobile telephone or a Set Top Box to set up an IPTV session. The invite message includes a Bootstrapping Transaction Identifier (BTID) associated with the IPTV receiving node. The AS sends an authentication request including the BTID to a Bootstrapping Server Function (BSF). The AS then receives from the BSF, an authentication response, which includes a long-term key associated with and previously provided to the IPTV receiving node. The AS then sends a request identifying the receiving node to an IPTV content provider. The AS then uses the long-term key to encrypt a media encryption key that is used to encrypt the media sent by the content provider, and sends the encrypted media encryption key to the IPTV receiving node in an invite response. | 03-17-2011 |

20120087581 | Methods and Arrangements for Image Processing - The present invention relates to methods and arrangements for compressing images. The invention is based on the fact that edge blocks contain much information in one direction (across the edge), but very little information in the other direction (along the edge). By encoding edges explicitly, it is possible to obtain a high quality to a very low cost for many blocks. A block is encoded by first specifying the orientation of the edge in the block, and then specifying the profile across the edge using a function with a small number of parameters. | 04-12-2012 |
