Abstract
In a method for recording video images and the associated sound with a reduced resolution, in such a manner that the recorded information can be reproduced by means of standard equipment, video frames are filtered so as to derive browse sets having a reduced number of pixels. A number of 16 browse sets are stored in a frame memory in order to form a mosaic frame of 4×4 browse sets, after which the mosaic frame is recorded. Audio samples are processed to form audio browse samples: the most significant half (MSH) of the bits of a first audio sample is used as the MSH of an audio browse sample and the MSH of a ninth audio sample is used as the least significant half (LSH) of the bits of this audio browse sample, which is subsequently recorded. In this way, the information required to edit a recording is reduced by a factor of 16.
