The invention relates to data reception, comprising: a step of reception of a file description table, a step of a request for transmission of at least a part of an object which has not been correctly received or has not been received, referred to as the fragment to be retransmitted, said transmission request comprising an identifier of the object to which said fragment to be retransmitted belongs and an identifier of said fragment to be retransmitted. In order to optimize the repair of an object (for example a file) which has not been correctly received, the transmission request furthermore contains an identifier of the version of the object.

The invention concerns a method for broadcasting digital video services including a step of transmitting digital video broadcasting services in radio frames addresses to at least one terminal having a standby mode and a sleep mode. In order that the terminal may stay in standby mode to receive data the modified content of the radio frames, at least a part of the radio frames comprises information representative of a change in the content of the radio frames. The invention also concerns a reception method implemented in the terminal as well as the corresponding devices.

Method for connecting an IEEE1394 remote device to a cluster of IEEE1394 devices through a wireless link comprising a first wireless device connected to the cluster and a second wireless device connected to the remote device, wherein the remote device and the first wireless device for a first wired bus and the device cluster and the second wireless device form a second wired bus. The method comprises the steps of, representing the remote device on the cluster through the first wireless device and representing the devices of the cluster to the remote device through the second wireless device, such that the remote device and the devices of the cluster function as if these devices were part of a single IEEE1394 bus.

The invention relates to a process for managing resources in a communication network comprising at least two communication buses linked by way of a wireless transmission bridge, the said bridge comprising for each bus a real portal connected to this bus, each portal being furnished with wireless communication means. The process is characterized by the steps: modelling the said wireless bridge by each real portal in the form of virtual buses and virtual bridges, each virtual bridge comprising two virtual portals; emulating a global register of passband availability for the entire wireless bridge; reserving passband with the said global register for each wireless link participating in a communication. The invention applies in particular in field of home automation.
摘要:
A method for transmitting first packets encapsulated in second packets in a transmission system in which part of the first packets contain a first timing reference for synchronization of a receiver clock and at least part of said second packets contain a second timing reference for reducing transmission jitter of the second packets at the receiver is described. This method is characterized by the steps, at the transmitter, collecting first packets, determining whether a collected first packet contains a first timing reference and triggering transmission of a second packet encapsulating collected first packets including said first packet containing the first timing reference in response to a positive determination.
摘要:
The invention relates to a device for interfacing between at least two communications buses. The device includes a two-way interface for each of the communications buses, a circuit for comparison of messages received by the interfaces, and a circuit for resolving conflicts of priority between messages overlapping in time so that the conflict resolution circuit authorizes the transmission of the higher priority message through the interface or interfaces to the communications buses from which the higher priority message did not originate.
