摘要:
A method of managing auxiliary programs broadcast with main programs in a digital data stream, wherein the method is implemented by a receiver, involving receiving several digital data streams including the aforementioned digital data stream, detecting data identifying all the auxiliary programs contained in said digital data stream, extracting all the auxiliary programs identified in the stream, and storing all of the auxiliary programs identified and extracted from the digital data stream, wherein the extraction is followed by analyzing execution commands associated with the extracted auxiliary programs.

Methods for transmitting first packets encapsulated in second packets in a transmission system in which part of the first packets contain a first timing reference for synchronization of a receiver clock and at least part of said second packets contain a second timing reference for reducing transmission jitter of the second packets at the receiver is described. This method provides, at the transmitter, collecting first packets, determining whether a collected first packet contains a first timing reference and triggering transmission of a second packet encapsulating collected first packets including the first packet containing the first timing reference in response to a positive determination.

The invention relates to a method for controlling of the display of audio-visual program by a receiver provided with means of receiving and recording audio-visual programs. The method comprises a step of recording a first program selected by the user; and subsequent to an action by the user to display the recorded program, a step of playback a program of a second type pre-recorded in the recording means (this program being for example of an advertising type), and a step which consists in displaying the second type program before the end of the first program display for a time interval stored in the receiver, the display of the first program being conditional to the display of the second-type program. The invention is characterized in that it comprises an improvement, whereby the receiver keeps an account of the duration of display of programs of the second type and authorizes unconditionally the display of programs after a certain duration. The invention also concerns the receiver adapted to display program in accordance with the method.

The present invention relates to a method for the distribution of multimedia content, comprising: a first step comprising a download in “push” mode of a multimedia content, in a partial way, from a content server to a client device, and a second step comprising a download of the missing elements of said multimedia content in “pull” mode via a “peer to peer” mechanism from a second client device, and in that the multimedia content can be reconstituted with n+p blocks, n and p being non-null natural integers, n blocks being downloaded during said first step and p blocks being downloaded during the second step, the multimedia content being exploitable only after reception of n+p blocks.

The invention allows a user, wanting to receive, on the one hand, a digital television offer broadcast in a conventional manner, and, on the other hand, an offer of video services on an IP network, to have a conventional receiving device capable of redistributing on the local network the services that he receives. This receiver will therefore be seen on the network as an additional source of IP services. The conventional service offer will be incorporated into the IP services offer.

This method of managing auxiliary programs broadcast with main programs in a digital data stream comprises: a step of receiving a plurality of digital data streams including said digital data stream; a step of detecting data identifying all the auxiliary programs contained in said digital data stream; a step of extracting all the identified auxiliary programs in the stream; and a step of the receiver storing all of the auxiliary programs identified and extracted from the stream. It advantageously includes a step of access to an auxiliary program which includes a substep of fast transmission of all or a portion of the stored auxiliary program.
