Abstract

A synchronous data transmission system for transmission of data between two communication partners, of which one serves as a transmitter and one as a receiver, comprising a clock signal producer which produces a transmission clock signal with a transmission clock signal rate from the transmitter to the receiver, which during the occurrence of one of the events equals an event specific transmission clock signal rate associated with the arising event and during an event free period of time equals a fundamental clock rate different of all event specific transmission clock signal rates.

First claim

The invention claimed is:

1. A data transmission system for synchronous transmission of data between two communication partners, of which one serves as a transmitter and one as a receiver, comprising:
an event monitor, which monitors for occurrence at said transmitter of at least one predetermined event, and, in the case of occurrence of one of these events, displays the occurring event during its occurrence as an event occurring at said transmitter;
a clock signal producer connected to said event monitor and having an adjustable clock frequency, which produces a transmission clock signal with a transmission clock signal rate, which during the occurrence of one of the events equals an event specific transmission clock signal rate associated with the arising event and during an event free period of time equals a fundamental clock rate different from all event specific transmission clock signal rates;
a transmission system, which transmits data signals corresponding to the data to be transmitted with said transmission clock signal rate from said transmitter to said receiver, and which transmits said transmission clock signal from the transmitter to the receiver; and
at said receiver and connected to said transmission system, an event recognition system, which, based on said transmission clock signal rate of the transmission clock signal, detects occurrence of one of the events at the transmitter, and, in the case of its occurrence, determines and outputs the event.

2. The data transmission system as claimed in claim 1 , further comprising:
connected to the event recognition system, an apparatus for performing at least one action associated with one of the monitored events, which apparatus effects especially an automatic performance of the action, as soon as the event recognition system outputs the occurrence of the associated event.

3. The data transmission system as claimed in claim 1 , wherein:
a number of the monitored events can occur simultaneously at the transmitter;
a event hierarchy is predetermined, in which the individual possible events are classified corresponding to their relevance; and
the event monitor, in the case of simultaneous occurrence of a plurality of events, shows that event as arisen event, which according to the event hierarchy should be attributed the highest relevance.

4. The data transmission system as claimed in claim 1 , wherein:
said event monitor, said clock signal producer and said event recognition system are provided in each of said two communication partners, and it is monitored in each of said two communication partners for occurrence there of at least one event predetermined for the respective communication partner, and in the case of its occurrence it is recognized by the respective event monitor and transmitted via said transmission system to the respective other communication partner.
