    摘要： A method and a device for downloading an audiovisual content from a data network. A description file describing the sub-dividing of the audiovisual content into a set of segments includes at least two pieces of information representative of respectively two segment download paths, each piece of information representative of a download path being associated with a network interface, and at least two network interfaces being distinct. The downloading device obtains at least one piece of information on distribution of requests for downloading segments by network interface, and for at least one segment of the audiovisual content to be downloaded, it selects a network interface from among the network interfaces associated with the download paths included in the description file, as a function of the information on distribution of requests obtained. A segment download request is then sent via the selected network interface.

    摘要： A method for generating a first video stream representative of a mosaic of videos, referred to as a video mosaic, from a set of at least two second video streams each consisting of a video associated with header data and encoded video data representative of images. During the course of the method: the encoded video data of the second video streams are stored during the generation of the first video stream, a header associated with said video mosaic is generated, said header being representative of an assembly of the encoded video data from the second video streams, and comprising: first header data which are legacy header data from each of the videos of the set of second video streams, second header data which are generated separately from the header data of the second video streams. Associated computer program, storage media and terminal.

    摘要： A method is provided for accessing a multimedia content containing at least one data segment. This data segment is accessible via a document describing the content. The method includes a first step of obtaining the document describing the content, from which document at least a first universal address of a segment is generated; a second step of obtaining at least one parameter associated with the universal address of the document describing the content; a step of reading at least one address generator rule in the document describing the content; and as a function of the address generator rule, of the first universal address of the segment, and of the parameter that has been obtained, a last step of generating the second universal address for the segment. Also provided is a method of generating a document that is suitable for use in the context of the access method.

    摘要： A method is provided for processing an error during restitution of digital content during a multimedia session on a terminal. The session offers a plurality of representations of the digital content which are described in a medium carrying information describing the multimedia session and transmitted independently of the representation data. The method includes, following the obtaining of the description-carrying medium, acts of obtaining, for at least one representation indicated in the description information-carrying medium, at least one item of information regarding guarantee of availability of the data of the representation on a server; of comparing the information regarding guarantee of availability of the data of the representation on the server with at least one predetermined value; of selecting a fallback representation as a function of the result of the comparison, and upon detecting a restitution error, of toggling to the fallback representation selected.
