<p>Data processing unit (15) for processing audiovisual input data from a data source (19), such as a digital video camera and a surveillance module (1) with a data processing unit (15). The data processing unit has a number of data encoders (20, 21) connected to the data source (19), which operate on the audiovisual input data in parallel. A first one (20) of the plurality of data encoders operates to provide an encoded lossless data stream (22), and a second one (21) of the plurality of data encoders operates to provide a real time data stream (23) with a reduced bit rate compared to a bit rate of the encoded lossless data stream (22).</p> |
