Abstract
A method for processing data packets of a data stream, in which the received data packets are processed in real-time by a first unit and only data packets that are received error-free are processed by a second unit, include a data sink initially receiving only the data packets processed by a first unit. Once a second unit and the first unit are processing identical data packets nearly simultaneously, data packets processed by the second unit can be routed to the data sink. Embodiments of the invention can be used advantageously in video coding, for example with a video-on-demand service or image analysis within the framework of a surveillance system.
