The present invention concerns a method for downloading content using a combination of push and pull modes. In a communication system comprising a first terminal, at least a second terminal, and a content server, the invention concerns a method for downloading content comprising, at the level of the first terminal, the steps of downloading content either in a pull mode from the content server or at least the second terminal or in a push mode from the content server; and seamlessly switching between the modes for continuing downloading of the content.

System and method for combining pull and push modes

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.

File repair method for a content distribution system

A device is dedicated to assisting the reconstruction of synchronization signals, for example within an item of communication equipment of an IP network. This device comprises i) a phase-locked loop charged with reconstructing, on the basis of a second sampled ramp signal received, a reference clock signal and a second ramp signal identical to, and in phase with, that having been sampled, and ii) processing means charged with determining in a first sampled ramp signal received, representative of a synchronization signal to be reconstructed and each sample of which is associated with a sample of the second ramp signal corresponding to a determinable sampling period, the value which corresponds to the first sample of this first sampled ramp signal received as well as the sampling period corresponding to this value, and then to initialize with this value a synchronization counter which is synchronized with respect to the second reconstructed ramp signal, on the basis of the reconstructed reference clock signal.

Device for generating a sampled ramp signal representative of a synchronization signal, and device for assisting the reconstruction of a synchronization signal, for a packet switching network

The invention relates to a method, a device and a system for the discovery of services according to a services entry point discovery protocol, that improves the discovery of audio/video services, in particular when several entry points, or access points, offering different services or different conditions for transmitting services can be offered to a user.

Method of receiving audio/video services, corresponding terminal and system

The present invention relates to a method of adjusting the sound levels originating from several audio sources, within a television receiver. The audio components originating from at least two audiovisual or audio sources are received in an audiovisual receiver and mixed so as to generate a single audio signal. The levels assigned to each source can be adjusted by the user with the aid of an icon displayed on a screen. The icon comprises at least two points representing the two sources and a cursor which moves along two dimensions, the distance between this cursor and the point representing a source being proportional to the sound level assigned to this source. The present invention also relates to the audiovisual terminal for the implementation of the method.

Method for sound adjustment of a plurality of audio sources and adjusting device

The invention relates to a method of controlling devices linked by a digital communication network, a device having a control device&#x2014;typically a remote control&#x2014;that is dedicated to it; the control device comprising command input means&#x2014;typically keys&#x2014;for entering commands. The method consists initially in running on each device to be controlled a step for configuring the associations between network device functions and command input means, then, when a means is activated, in sending a message including the code corresponding to the device associated with this key. A refinement consists in associating a number of devices with one and the same key, and in sending as many messages as there are associated devices when the key is activated. The invention also relates to a device provided with a remote control and an interface for implementing the method.
