Abstract
A video-processing device is provided for processing a main video data flow and a secondary video data flow. The secondary video data flow constitutes a scaled version of the main video data flow. The video-processing device comprises a tap-off unit (T, T) having an input for receiving the main video data flow. The tap-off unit (T, T) comprises at least a first and second output, wherein each of the outputs corresponds to the input of the tap-off unit. A first H- and V-scaling unit (HVS) is coupled to the first output of the tap-off unit (T, T) for performing a first H- and V-scaling on the main video flow. A second H- and V-scaling unit (HVS) is coupled to the second output of the tap-off unit for performing a second H- and V-scaling on the secondary video flow to provide a scaled secondary video flow. By tapping-off the main video flow there is no need for the device to access a memory to extract the video data from the main video flow to provide a secondary video flow.
