Abstract

In order to provide a recording method for data which have been or are being generated at a data source in a time sequenced manner and are transmitted via a digital network to at least one recording device for storage, by means of which method the data can be reliably recorded, it is provided that the data are stored at the data source before the transmission on the digital network in such a way that, after a fault on the digital network, data which were intended for transmission during the period of the fault can be made available to the at least one recording device.

Claims

1. Recording device for video/audio data, comprising:

an interface for a digital network, via which data are receivable from the digital network;

a memory for recording the data, and

a detection apparatus for emitting test signals to the digital network at fixed time intervals in order to be able to detect faults of the data transmission from a data acquiring device;

a control apparatus, by means of which, after a detected fault, received data which have been recorded during a period of the fault and are transmitted after ending of the fault are written into the memory in a data gap in a correct time sequence.

2. Recording device according to claim 1, wherein a registration apparatus is provided, by means of which changes in status with respect to faults in the data transmission are registerable.
