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:
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:
In order to share digital data in a peer to peer communication network, a partial version of the data is firstly transmitted to destination stations, and: a collection of data is created in which an identifier is associated with each data item and to each data identifier there is allocated a label indicating whether the complete version of the data item is available on the network; the existence of the collection is notified to at least one destination station; and, on the reception of information on availability on the network of the complete versions of the data of the collection: the collection is updated; and the updating of the shared collection is notified to the destination station or stations.
