20090158366 | Method for optimising the transmission of DVB-IP service information by partitioning into several multicast streams - The present invention relates to a broadcast server of service information data streams, comprising a first step consisting in partitioning at least one part of the service information between the different streams, and a second step consisting in broadcasting the partition from the first step on at least two separate streams to a plurality of terminals. | 06-18-2009 |
20090165042 | Methods of receiving and sending digital television services - The invention relates to a method of receiving digital television services, which comprises a step of receiving at least one information representative of the lag in the display of a new service, the information being inserted into control data which comprise at least one list of services. Thus, the invention allows the receiver to perform an action during the loading of a service as a function of this time. The invention also relates to the corresponding sending method. | 06-25-2009 |
20090240701 | File repair method for a content distribution system - The present invention concerns a file repair method for recovering a file, in a system for distributing content to more than one receiver, comprising, at a first receiver, the steps of receiving a set of files in a push multicast from a transmitter, receiving an identifier of a second receiver that owns a missing file that is not comprised in the received set of file; and recovering the missing file from the second receiver in a pull mode using a peer-to-peer mechanism. Another object of the invention is a method for file recovery in a server and in a peer device. | 09-24-2009 |
20130120662 | METHOD OF DIGITAL CONTENT VERSION SWITCHING AND CORRESPONDING DEVICE - The present invention relates to the field of management of digital content switching and in particular to the optimization of digital content version switching in order to ensure smooth switching between different versions of digital content during rendering. Different versions are for example: an uncensored version and a censored version, a cinema version and a TV-series adaptation version of a same digital content, a version with inserted publicity and a version without, a trailer version and a cinema version, different language-dubbed versions. | 05-16-2013 |
20140208374 | METHOD AND APPARATUS FOR ADAPTIVE TRANSCODING OF MULTIMEDIA STREAM - A method of streaming an output content stream adaptively transcoded from a corresponding input content stream includes offering, to a client device, a number of alternative versions of the output content stream, for selection by the client device, and dividing the input content stream into two or more segments. Prior to the offering step at least a first segment of the input content stream is transcoded into at least one corresponding segment of an output content stream corresponding to at least one version from the number of alternative versions offered to the client device. Upon receiving a request from the client device for a selected version of the output content stream, streaming is begun with using a first one of the at least one corresponding segments of an output content stream corresponding to at least one version from the number of alternative versions offered to the client device that had been transcoded and stored prior to offering. Transcoding parameters are extracted from the request, for controlling the transcoding of a subsequent segment of the input content stream into the version selected by the client device, and the subsequent segment transcoded into the requested version is streamed to the client. | 07-24-2014 |
20140250231 | METHOD FOR CONTROLLING BANDWIDTH AND CORRESPONDING DEVICE - The present invention concerns a device and a method at the device, the device comprising a first interface to a first network comprising an adaptive streaming server, a second interface to a second network comprising at least one adaptive streaming client device, a stream identifier for detecting at least one streaming content requested by the at least one adaptive streaming client device, the at least one streaming content being available at more than one data rate, a bandwidth manager for selecting a data rate among the more than one data rate, a scheduler for transmitting at the second interface the at least one streaming content to the at least one client device at a data rate above said selected data rate but below any higher data rate available for said streaming content. | 09-04-2014 |
20150127848 | METHOD AND APPARATUS FOR PROVIDING A PLURALITY OF TRANSCODED CONTENT STREAMS - A method of providing a plurality of versions of a content stream with different bit-rates is suggested. According to the method a set of versions of a content stream with different bit-rates is offered to a client. A manifest part describing the offered set of versions of the content stream is submitted to the client. The client requests one version of the content stream having a specific bit-rate. The bit-rate of the versions offered to the client is dynamically selected such that the difference between bit-rates of neighbouring versions is dynamically adapted. The suggested method improves adaptive transcoding so that it uses a small manifest part based on a small set of bit-rate values distributed around the currently delivered bit-rate. In addition to that a system is suggested for implementing the method. | 05-07-2015 |
20150200992 | METHOD FOR DOWNLOADING, AT A CLIENT TERMINAL, AN UPCOMING SEQUENCE OF SEGMENTS OF A MULTIMEDIA CONTENT, AND CORRESPONDING TERMINAL - The disclosure relates generally to the domain of the adaptive streaming technology over, for instance but not exclusively, HTTP (HyperText Transfer Protocol). A method and a system are described for downloading at a client terminal an upcoming sequence of segments of a multimedia content, with each segment being derived from one or more representations. | 07-16-2015 |
