摘要： The invention relates to a method for navigation in a panoramic video sequence displayed on a user terminal. The video sequence is divided into a plurality of non-overlapping video patches each corresponding to a zone of the video sequence. The video patches required to form a zone of the panoramic video sequence to be displayed on a screen of the user terminal, called the visibility zone, are determined according to navigation commands.According to the invention, the video patches are provided to the user terminal, for one part, via a first transmission network and, for another part, via a second transmission network distinct from said first transmission network.

摘要： A method for delivering content to at least two terminals for synchronous playback is described. The method includes providing a first association of content to a preamble sequence, providing a second association of content to an ending sequence, providing estimations of data delivery duration from a server to at least two terminals and a playback duration of the preamble sequence in at least one of the first and second association, delivering the first and second association to the terminals wherein the playback duration of the preamble sequence is greater than or equal to the largest difference between the estimations, and wherein the estimations of data delivery duration allows each of the at least two terminals to evaluate a local temporization duration for playing-back synchronous content.

摘要： The invention consists of a process for receiving and for screening audiovisual transmissions broadcast by a network. The transmissions consisting of events and of short transmissions possessing a distinctive element, these short transmissions being broadcast by services identifiable by this distinctive element. At a certain moment specified by the broadcaster, a sequence is transmitted on the network, it is replaced at the level of the display of the receiver by another sequence extracted from a service broadcasting short transmissions. The choice of this service is made at the receiver level. To avoid the appearance of a black screen between the network's transmitted sequences and the short transmissions, the receiver dispatches a filler transmission to the screen.The invention also consists of a digital television receiver for implementing the process.

摘要： Within the framework of a wireless local area network, the sending of the multipoint transmission streams is not made reliable by an acknowledgment of receipt mechanism. This reliability may be improved by the sending in point-to-point mode of the packets belonging to a multipoint transmission stream. In the case of a digital service consisting of several streams of different priorities, it is possible to send only some of these streams in point-to-point mode while the other streams remain in multipoint. A gateway between the local area network and the exterior may be tasked with this selective transformation of the mode of transmission of the streams received.
