In this paper different approaches for digital video recording in vehicles are examined, with weight on video quality. Different video compression algorithms were gone through and the conclusion was that inter-frame compression, like MPEG video delivers better video quality than intra-frame algorithms, for example Wavelet. The main drawback is that it is difficult to extract single frames, which leads to difficulties when for example backwards-playability is needed. To demonstrate how digital video recording can be done a demonstrator was built. Therefore, when the decision to use MPEG compression was made, a market research was done and a video grabber expansion card for PCs was bought. The report describes the hardware and software developments that had to be made to run the video recorder. The result of the thesis was this report and a functioning recorder. The delivered video quality was fair and it was also remote controlled.
