System for the transmission of data in an installation, notably a domestic installation
First Claim
1. A system for the transmission of data elements in an installation having a plurality of devices connected into a network of an information transmission medium, each device being capable of receiving and sending data elements at one of at least two predetermined transmission speeds, wherein said system further comprises at least one relaying device, said relaying device including means for receiving and means for transmitting data elements at each of said at least two predetermined transmission speeds so as to allow the transmission of data elements among devices from the plurality of devices working at different transmission speeds by relaying the data element at an appropriate speed, the means for receiving and means for transmitting operating responsively to an indicative signal, said means for receiving including recognition means for estimating the transmission speed of a data element received by the relaying device by analyzing a first portion of the data element and including confirmation means for confirming whether the speed estimated by the recognition means is correct by analyzing a second portion of the data element, the confirmation means providing the indicative signal to the means for receiving and means for transmitting.

Abstract
The system for the transmission of data in an installation having a plurality of devices connected into a network, the devices being capable of receiving and transmitting data elements at one of at least two transmission speeds. The system further includes a relaying apparatus having a mechanism for receiving and transmitting data at each of the transmission speeds so as to provide for the transmission of data elements among the devices working at different transmission speeds.

11. A method for transmitting and receiving data elements from a plurality of devices connected into a network, wherein each device is capable of receiving and transmitting data elements at one of at least two predetermined transmission speeds, the method comprising the steps of:
-
a) a first device transmitting a data element at a first transmission speed on the network; b) a relaying device receiving the transmitted data element from the first device and estimating the transmission speed at which the data element was transmitted by analyzing a first portion of the data element; c) the relaying device confirming whether the estimated speed is correct by comparing a header of the data element with a stored value corresponding to the estimated speed; d) if during step (c) the relaying device confirms that the estimated speed is correct, the relaying device transmitting the received data element on the network at a second transmission speed. - View Dependent Claims (12, 13, 14)
