8 Bit Convertors for Video Applications

Increasingly, the improvement of the quality of TV pictures and new features as satellite TV and scrambled TV lead to digital processing of the video signal. As a consequence, A/D and D/A converters able to handle video signals become essential in this approach. Of course such devices are now commercially available and are used in a variety of professional pieces of equipment, but their price is hardly compatible with their use in a consumer TV set. In such applications the integration of a number of components allows the reduction of the price of the overall system to a level commercially acceptable. This was the background of a study* of A/D and D/A converters carried out at LEP** with the objective of reducing drastically the component count around each converter.
