Abstract: A recording device for a recording of a serialized image data stream from a sensor device. The recording device comprises a deserializer for deserializing the image data stream. To configure the first deserializer, the recording device comprises a configuration device, which records a configuration data stream transmitted by a receiving device for the purpose of configuring a serializer arranged in the sensor device and derives a configuration of the deserializer of the recording device by an analysis of the recording of the configuration data. In an example, the derivation takes place by an abstraction of the configuration of the serializer into a functionality of the serializer, a derivation of a functionality of the first deserializer from the functionality of the first serializer, and a concretization of the functionality of the first deserializer into a configuration of the first deserializer.
