20080310497 | Method For Filtering, Transmitting and Receiving Scalable Video Streams, and Corresponding Programs, Server, Intermediate Node and Terminal - A method is provided for filtering a scalable video stream, organized in the form of data unit blocks, each of which comprises a base data unit and a set of data units distributed according to two types of enhancement data, corresponding respectively to time and/or space and/or quality characteristics and making it possible to define several quality levels. The method defines at least two distinct filtering profiles, or paths of each block data units, wherein each path defines a row of successive foldover positions and each foldover position uses at least by one less data units than a previous position, and selects one of the paths according to a predetermined criterion, taking into account the type of content of the stream and/or at least one information item representing the capacities of a terminal receiving the stream. | 12-18-2008 |

20100005184 | METHOD AND DEVICE FOR ADAPTING A SCALABLE DATA STREAM, CORRESPONDING COMPUTER PROGRAM PRODUCT AND NETWORK ELEMENT - The invention relates to a method of adapting a scalable data stream organized in blocks of data units, each comprising at least one basic data unit and at least one enhancement data unit, making it possible to define a plurality of quality and bit rate levels (N | 01-07-2010 |
20130036204 | RECEPTION OF A DIGITAL CONTENT IN TRICK MODE - A terminal receives a digital content which is transmitted in the form of a data stream in a network. This digital content is received by the terminal with a reception throughput, a nominal rendering time being associated with the digital content. Activation of a trick mode corresponding to a modification of the nominal rendering time according to a modification factor associated with the trick mode is detected on the terminal. Data to be requested are then determined according to the modification factor and according to a value representative of reception throughput. The data are then requested from the network and the requested data are received. | 02-07-2013 |
20140129893 | Retransmission of Data Lost Between a Sender and a Receiver - A method is provided for receiving a realtime data stream transmitted at a given speed in the form of packets between a transmitter and a receiver in a telecommunication network. The receiver has a buffer memory for storing the received packets. The method includes the following steps after detection of a loss of packets: requesting retransmission of the lost packets at a speed that is higher than the given speed; receiving retransmitted packets and realtime packets, the retransmitted packets having been transmitted with priority in relation to the realtime packets; and storing the retransmitted packets in the buffer memory. | 05-08-2014 |
