    Abstract: A method is proposed for transmitting a multi-channel data stream comprising frames comprising a plurality of channels, the transmitting being done through a multi-transport tunnel from a first tunnel end-point to a second tunnel end-point, the multi-transport tunnel implementing a first carrier supporting a transport protocol with acknowledgement and a second carrier supporting a transport protocol without acknowledgement.The invention aims more specifically at averting or limiting the phenomena of interruptions in the rendering of a multi-channel stream in transit on a tunnel, and more particularly at providing a transport technique enabling regular and uninterrupted delivery of the multi-channel stream while at the same time reducing the memory resources needed at reception.

    Abstract: A method is proposed for transmitting packets of a two-way passenger data stream set up between first and second terminal devices. The passenger stream is compliant with a passenger transport protocol with acknowledgement defining a plurality of packet categories, and is intended to be encapsulated by a manager device according to an encapsulating transport protocol with acknowledgement. The manager device obtains a packet of the passenger stream transmitted from the first terminal device to the second terminal device, makes a first check to see if the packet obtained belongs to at least one predetermined category among the plurality of packet categories and, in the event that the first check is positive, encapsulates at least one part of the data of the obtained packet according to an encapsulating transport protocol without acknowledgement.

    Abstract: A method is disclosed for transmitting a multi-channel data stream comprising frames comprising a plurality of channels, the transmitting being done via a multi-transport tunnel from a first tunnel end-point to a second tunnel end-point, the multi-transport tunnel implementing at least one first carrier supporting a transport protocol with acknowledgement and at least one second carrier supporting a transport protocol without acknowledgement.More specifically, the invention proposes to introduce a delay in the sending of data ( >) via the first carrier as compared with the sending of data ( >) via the second carrier. Thus the invention guarantees the order of arrival of channels that are associated with a same piece of synchronization but are transmitted on distinct first and second carriers and come from the separation of a same multi-channel data frame.

    Abstract: The method of asynchronous delivery of digital data according to the invention is implemented in at least one server system and at least one client system connected via a network. According to the method, at the time of a request for data coming from a client system, an item of context information (CINF) representing a first state of the client system on sending out the request is associated with the latter. On delivering to the client system a response, the response incorporates the context information (CINF). The client system is adapted to put itself in a second state analogous to the first state mentioned above, in accordance with the context information (CINF, CUID). The method according to the invention provides context management enabling the user to associate the responses received with requests sometimes made well beforehand.

    Abstract: A data stream is transmitted from a transmitting device to a receiving device via a communication network. Data of the data stream is transmitted to the receiving device by using a transport protocol without data acknowledgement. In a transmission method, parity-encoding parameters for parity encoding a data set of the data stream is determined via the transmitting device. The transmitting device also generates parity data from the data set by using the determined parity-encoding parameters. The transmitting device further transmits the generated parity data to the receiving device via the communication network by using a transport protocol with data acknowledgement.
