During the delivery of a sequence of packets from a server to a client device, when an expiration time associated with an initial payload of a data packet belonging to a sliding window for delivery is reached without reception of a corresponding acknowledgment from the device, the server () resends the data packet with a new payload corresponding to the initial payload of a next data packet to be transmitted through the sliding window.

Network equipment and method for delivering data packets

During a streaming session of tile based immersive video, upon request to switch from at a current tile segment associated with a current tile to a new tile segment associated with a new tile at a reference time, an encoder () is providing to generate one or more complementary frames of the new tile segment allowing a decoding, by a requesting player, of the new tile segment from the reference time.

Encoder and method for encoding a tile-based immersive video

According to embodiments, an enhancement layer segment may be requested in addition to a base layer segment for a same video. The enhancement layer may be requested, in a low priority, so that the base layer may be delivered in priority. If the enhancement layer can be obtained by a deadline, a subsequent base layer segment may be requested at a higher quality (e.g., at a bitrate lower than or equal to the sum of the bitrates of the previously requested base layer and enhancement layer segments). If, for example, at a playback time, the enhancement layer segment is not obtained, it may be determined that the quality cannot be increased and subsequent requests for enhancement layer segments may be cancelled (e.g., not transmitted). According to embodiments, probing may repeat (e.g., any of immediately, regularly, periodically, . . . ) to detect available bandwidth variations.

Method and apparatuses for sending and receiving a video

A terminal adapted to receive an immersive video spatially tiled with a set of tiles is configured to request tiles depending on their intersection with a volume of vision associated with a user.

Method configured to be implemented at a terminal adapted to receive an immersive video spatially tiled with a set of tiles, and corresponding terminal

A method and an apparatus for decoding a volumetric video are disclosed. Such a method comprises receiving a data stream representative of a file comprising information for selecting, according to a rendering viewpoint, at least one atlas comprising color and depth data patches associated with a viewpoint in said volumetric video, said color and depth data patches being generated with respect to depth and color reference data acquired from a reference viewpoint in said volumetric video.

Method and apparatus for decoding a 3D video

A client () is able to manage a multimedia content in such a way that the buffering can be reduced as much as desired down to zero by selecting a representation for a next segment to be requested for which the first frame can be received at least in the frame duration.

Client and a method for managing, at the client, a streaming session of a multimedia content

A method and a device provide for transmitting information representing a viewpoint in a 3D scene represented with a set of volumetric video contents; receiving a first volumetric video content of the set, the first volumetric video content being according to a range of points of view comprising the viewpoint, the first volumetric video content being represented with a set of first patches, each of which corresponds to a 2D parametrization of a first group of points in a 3D part of the 3D scene associated with the first volumetric video content, and at least one first patch refers to an area of a second patch corresponding to a 2D parametrization of a second group of points in another 3D part of the 3D scene associated with a second volumetric video content of the set of volumetric video contents.

Methods and apparatus for volumetric video transport

An encoder is configured for encoding an immersive video spatially tiled with a set of tiles in one or more representations in accordance with corresponding assigned bit-rate upper limits depending on obtained proximity values of the corresponding tiles.

Method and network equipment for encoding an immersive video spatially tiled with a set of tiles

The invention concerns a method for adapting the downloading behavior of a client terminal configured to receive a multimedia content from at least one server, said multimedia content being defined by at least one representation, wherein it comprises the steps of: requesting (S) a first part of said multimedia content with a given representation; detecting (S) if a cache between is located along the transmission path the client terminal and a server, based on the request of said first part; in case (S) a cache is detected, requesting a second part of said multimedia content with a representation depending on at least one performance criterion.

Method for adapting the downloading behavior of a client terminal configured, to receive multimedia content, and corresponding terminal

Cache (DANE) located along a transmission path between client terminals (CT) and at least one server (SE) and configured to receive requests from client terminals (CT) for segments of a multimedia content available at several representations, which comprises: &#x2014;an interface of connection () for receiving, from a first client terminal, a first request for a preferred representation and at least one alternative representation of a given segment of said multimedia content; &#x2014;a matching module () configured to determine if at least one ongoing representation of said given segment, already requested by the cache from a server for a further client terminal, matches the preferred representation or an alternative representation of the first request.

Method for operating a cache arranged along a transmission path between client terminals and at least one server, and corresponding cache

The invention concerns the exchange of parameters between communication devices of a network describing their respective data sessions and the application, at a communication device, of a bandwidth distribution algorithm using the exchange parameters to allocate bandwidth to one or more data sessions in the network.

Distribution of bandwidth in a network

First type cache adapted to be arranged between a client terminal and at least one server, which:

The invention concerns a device for reserving bandwidth for an adaptive streaming client belonging to at least one network and configured for receiving a streaming content from at least one server, the streaming content being available at more than one data rate at the server. The device includes a stream identifier configured for detecting at least one streaming content requested by the client, a bandwidth manager configured for temporarily reserving for the client, when at least one event occurs, a transient bandwidth depending on the predetermined target data rate associated with the requested streaming content and a transient margin.

Method and device for reserving bandwidth for an adaptive streaming client

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.

Method for controlling bandwidth and corresponding device

A cache arranged between client terminals and at least one server, said cache being configured to receive, from client terminals, requests for at least a first representation of a segment of a multimedia content available in a plurality of representations, comprising:
