20090207839 | MULTICAST DELIVERY - A method and nodes in a communication network for controlling multi-cast delivery of files, wherein the multi-cast delivery is adapted to reduce the amount of required uni-cast file deliveries in the communication network. A browser of an IPTV Terminating Function requiring a file interrogates a cache of the IFT for the file content before a uni-cast request for file delivery is sent to an Application Service Platform. The files stored in the cache have been previously delivered to the IFT via the proposed multi-cast mechanism. If the file content is not stored in the cache, a uni-cast request is sent to the ASP. Each uni-cast request is also forwarded to a Multi-Cast Controller, which determines whether the requested file should be sent also to a plurality of additional IFTs on a multi-cast channel. At each IFT, listening to the multi-cast channel, the received content can be handled selectively according to a filtering mechanism, and a received file may, e.g. be stored in the cache for later retrieval. | 08-20-2009 |
20090313376 | METHOD AND APPARATUSES FOR ESTABLISHING A SESSION BETWEEN A CLIENT TERMINAL AND A MEDIA SUPPLY SYSTEM TO TRANSPORT A UNICAST MEDIA STREAM OVER AN IP NETWORK - A method of setting up a session between a client terminal and a media supply system in order to transport a unicast media stream from the media supply system to the client terminal over an intervening IP network, the media supply system implementing the Real Time Streaming Protocol. The method comprises conducting a negotiation between the client terminal and the media supply system over an IP Multimedia Subsystem network in order to identify to the IP Multimedia Subsystem network the source and destination IP addresses and port numbers for the media stream, and subsequently sending Real Time Streaming Protocol messages from the client terminal to the media supply system in order to control the playout of media from the media supply system. | 12-17-2009 |
20100036964 | MULTI-MEDIA MANAGEMENT - A multimedia provider multicasts a main multimedia stream comprising a mixture of intra and inter frames and multicasts an associated auxiliary stream comprising intra frames. At least a portion of the intra frames in the auxiliary stream are generated based on same multimedia data as at least a portion of the inter frames of the main stream. The provider also transmits a stream information channel comprising information descriptive of time instances of intra frames in the main and auxiliary streams. This information allows a set top box to selectively connect, in connection with session set-up and channel switch, to the main or auxiliary stream to receive an intra frame with as a low delay as possible. | 02-11-2010 |
20100091772 | PROVIDING IPTV MULTICASTS - A method of operating a Reliable Transmission Protocol switch node to provide an IPTV multicast. IP packets transporting an encrypted media stream are received from an IPTV Head-end. The media stream contains complete image frames. Unencrypted identifiers identifying packets containing complete image frame data are also received. The received packets are stored in a buffer, and on receipt of a request from a media renderer to provide the IPTV multicast, the packet(s) containing the last complete image frame in the media stream and all subsequent packets are sent to the media renderer. | 04-15-2010 |
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 |
20110023065 | METHOD FOR PROVIDING A TELEVISION ELECTRONIC GUIDE - A method and apparatus for providing a packet switched television guide such as an Electronic Program Guide or an Electronic Service Guide to a user. An Application Server receives and stores preferences relating to a packet switched television guide. When the Application Server subsequently receives a new or updated packet switched television guide from a packet switched television Guide Application Server, the Application Server filters elements of the packet switched television guide according to the preferences to remove information not relevant to a user associated with the preferences. The filtered packet switched television guide is then sent to the user. In this way, only relevant information is sent, which can reduce the bandwidth required in sending packet switched television guides, the frequency at which packet switched television guide updates need to be sent, and also the processing required by the user's receiving equipment in filtering out irrelevant information from the packet switched television guide. | 01-27-2011 |

20110083153 | Method and Equipment for Providing Unicast Preparation for IPTV - A method for providing switching of a media session transmitted from server to a user equipment from a multicast to a cast bearer. A preparation trigger recognised by the user equipment triggers a preparation phase where in an application server prepares for an up-coming switch by re-configuring the media session and by providing the re-configuration data to the user equipment. Subsequent to the preparation phase, a second trigger triggers a release phase, wherein the multicast bearer is released, and the media session is resumed by the unicast bearer. | 04-07-2011 |

20130332974 | Method and Server for Fast Channel Change in Unicast-Multicast IPTV Networks - An object with embodiments of the present invention is to achieve a solution for fast channel change that improves bandwidth utilization, wherein the fast channel change is accomplished by initiating a unicast stream until a multicast stream can provide the desired media. The bandwidth utilization is achieved by delaying the multicast session and by terminating the unicast session at the latest when the multicast session starts. The delay of the multicast session is dependent on the network latency. Latency in this context refers to the time passed from when the client sends an IGMP JOIN message until it receives the first packet of the multicast stream. | 12-12-2013 |
