Definitions

  • the invention relates to a data acquisition / data processing device for video / audio signals, which comprises a plurality of signal processors.
  • the video / audio system described therein comprises at least one recording device which provides digital video / audio data, a plurality of processing devices (in particular signal processors), one processing device being assigned to at least one recording device, processing data from the associated recording device and provides modified data, and an evaluation device which is coupled to the processing devices and by means of which the modified data provided by the respective processing devices can be compared and evaluated in order to provide a selected data set optimized for an application.
  • processing devices in particular signal processors
  • the invention has for its object to provide a data acquisition / data processing device for video / audio signals of the type mentioned, which has an optimized hardware architecture.
  • the solution according to the invention results in a transparent hardware architecture.
  • the scalability is good, and the same linking philosophy applies to all assemblies of the device.
  • the line expenditure can be kept low, since, for example, only four signal lines are required per signal processor for the formation of the network.
  • the disturbance sensitivity is reduced. Problems with signal runtime and distance are avoided.
  • a dedicated bandwidth can be assigned to each module. Guaranteed bandwidths of, for example, 100 Mbit / s or 1000 Mbit / s or higher can be achieved.
  • a corresponding device can be manufactured inexpensively, since necessary hardware components such as hubs or switches are available as standard components.
  • a star-shaped wiring of the signal processors enables full duplex operation in all signal propagation directions (sending and receiving). This ensures real-time operation; Real-time processing of data is crucial for video and audio data.
  • the signal processors or a subset of the signal processors are linked to one another via the network with a star-shaped topology. This allows data to be exchanged between individual signal processors, and in particular all signal processors can communicate with one another at the same time. This makes it possible to implement the system described in DE 101 53 484 A1 with a plurality of processing devices and an evaluation device which is coupled to the processing devices in a simple and cost-effective manner.
  • the network is integrated in the device.
  • data communication between the signal processors of the device can be carried out in a simple and reliable manner.
  • signal runtime problems can be avoided.
  • the device then has a network microarchitecture, so that an external network macroarchitecture is no longer necessary.
  • the network microarchitecture in turn, can be optimally trained, for example in terms of bandwidth and hardware equipment (such as switches).
  • the network forms a backbone for the device, that is to say a backbone for the signal processors.
  • a hub, switch or port for the network is also possible for a hub, switch or port for the network to be arranged externally with respect to a housing which accommodates the signal processors. This results in easy interchangeability, for example.
  • connection for coupling in video / signals.
  • digital video / audio data which are provided by a digital video camera or by an analog camera with subsequent digital conversion, can be coupled into the device in order to be able to record or process the data.
  • data compression and / or data evaluation can be provided.
  • a video / audio system in accordance with DE 101 53 484 A1 can thereby be implemented, in which an evaluation device is coupled to a plurality of processing devices and by means of which the modified data provided by the respective processing devices can be compared and evaluated in order to obtain a for to provide an application selected optimized record.
  • This data record can then be transmitted to a storage device, for example, via a digital network.
  • connection is coupled to a hub, switch or port of the network of the device, so that external communication is also possible via the network.
  • the digital network thus enables internal communication between the signal processors of the device and communication between the signal processors and, in particular, transmission of data from the signal processors to the outside.
  • FIG. 1 shows a schematic block diagram of an exemplary embodiment of a data acquisition / data processing device according to the invention.
  • the cameras 20a, 20b, 20c provide video data.
  • the device 10 receives in particular digital video signals.
  • a digital camera already provides digital video signals.
  • An A / D converter can be connected downstream of an analog camera in order to convert the analog video signals into digital signals.
  • the reference symbols 20a, 20b, 20c refer to a digital camera or a digital microphone or an analog camera / an analog microphone with a downstream A / D converter.
  • the coupled data can be analyzed.
  • a data comparison can be carried out, for example, via a signal processor 22c.
  • the use of the network 28 with a star-shaped topology and in particular the use of the Ethe net standard means that the outlay on lines can be kept low, since only four lines have to be provided for each signal processor 14. This in turn can simplify production. There are no problems with signal runtime and distance. Hardware modules such as hubs, switches and ports are also available. There is also good scalability. The sensitivity to interference is also reduced. Each module, for example the signal processors 22a, 22b, is assigned a specific bandwidth, which can then also be used accordingly.
