An encoder (122) comprises a module (123) for analysing digital, advantageously audio-visual, content (CNT) to be encoded and a module (124) for encoding the content (CNT). The analysis module (123) detects the parts of the content that may be dropped or duplicated with minimum effect to the digital content (CNT) when it is rendered so as to be rendered with little disturbance to the user, e.g. a completely black frame of video, and indicates this to the encoding module (124) that tags the encoded content (CNT') accordingly. A decoder (142) may then drop or duplicate parts of the content if needed owing to buffer fill problems, preferably at sample boundaries, and it is advantageous that the decoder (142) drops or duplicates continuous content and modifies the rendering of discrete content to keep synchronization, if the content comprises such parts.

The present invention relates to a method at a receiver for playing a stream comprising a set of discrete samples adapted to be rendered at a standard rendering speed, comprising at the receiver the steps of starting the reception of the stream, starting the rendering of the discrete samples at a speed slower than the standard speed and accelerating the rendering speed up to the standard rendering speed. The invention also concerns methods for an early rendering of continuous samples, when the stream comprises a set of continuous samples, wherein the continuous and discrete samples being adapted to be rendered at a standard rendering speed in a synchronized manner.

The present invention relates to a broadcast server of service information data streams, characterized in that it comprises: - 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. The present invention also relates to a broadcast server of service information data streams.

This invention can be used to play back an audiovisual or audio document received in a first encoding format within a local area network. A first device plays back the document in the received format, then a user decides to play back the document on a device having a second encoding format. Playback is first stopped on the first device and the document is stored. The user starts playing back the document on the second device at the moment at which playback of it was stopped on the first device. Depending on the decoding means of the second device, the document is transcoded from the first encoding format to the second encoding format. The invention also relates to a management device for issuing storage and transcoding requests so that a document played back from a first device can be transferred to a second device regardless of the capabilities for playing back encoded documents on the first and second devices.

The invention relates to a method of management of trick mode commands destined to control a digital content streaming server (125). In order to manage the transmission of trick mode commands from multiple trick mode command issuers, the method comprises: - a step of reception (501) of at least one trick mode command from at least one command issuer, - a step of determination of elapsed time (502) between the received command and a last transmitted command, and - a step of transmission of the received command (505) to the at least a digital content streaming server if none of determined conditions applies, whereby the determined conditions comprises: if the elapsed time is smaller than a determined first delay (503); and if the command issuer of the received command does not have highest issuer rights (504) allowing the issuer to derogate from respecting of the determined first delay.

The present invention concerns a receiver, a router device, and a method at a receiver (5) for receiving content from at least one source address (3), said receiver being connected to at least one router (1) that permits the receiver to connect to said at least one source address. to this end the method comprises the steps of receiving an indication (S1) that said content is distributed on a multicast address, from at least one source address, receiving an indication (S2) that said content is distributed on at least one port of said multicast address from at least one port of said at least one source address, selecting (S3) at least one port among said more than one port and reporting (S4) said selection to said at least one router.

La présente invention concerne essentiellement un procédé de transmission, via un réseau de communication utilisant un protocole de transmission de données par paquets, d'un flux d'échantillons multimédia entre un serveur émetteur et au moins un récepteur décodeur destiné à restituer ces données en temps réel, ce flux d'échantillons codant des images (I, P, B) de taille variable, caractérisé en ce que le procédé comporte notamment les différentes étapes consistant à : - déterminer un même délai de transmission pour l'ensemble des échantillons du flux; - déterminer un débit (39) de transmission pour chaque échantillon permettant l'envoi de cet échantillon dans le délai de transmission déterminé; - émettre chaque échantillon depuis le serveur émetteur vers le récepteur décodeur en respectant le débit (39) de transmission propre à cet échantillon et le délai de transmission de l'ensemble des échantillons.
摘要:
In certain home multimedia networks having a plurality of terminals, there are no provisions for sending error messages when a service cannot be delivered owing to conflicts with another service. The present invention proposes to let the media server of the tuner (230) in such a network (120) provide an image bearing the message and deliver this image to the terminal (150, 155) that otherwise would be left in the dark.
