The two’s complement system allows two sample values to be added, or mixed in audio and video parlance, and the result will be referred to the system midrange; this is analogous to adding analog signals in an operational amplifier.

This makes a magazine a non-linear or random-access medium. The development of the consumer VCR was a small step to end the linearity of commercial television. Increasing numbers of viewers use VCRs not just as time shifters but also as a means of fast-forwarding through the commercial breaks. The non-linear storage of video was until recently restricted by economics to professional applications. However, with the falling cost of hard drives, non-linear video storage is now a consumer product. 27 In a hard disk recorder, a large-capacity memory is used as a buffer or timebase corrector between the convertors and the disk.

In optical disks, random errors can be caused by imperfections in the moulding process, whereas burst errors are due to contamination or scratching of the disk surface. Before attempting to specify an error-correction system, the causes of errors must be studied to quantify the problem, and the sensitivity of the destination to errors must be assessed. In video and audio the sensitivity to errors must be subjective. 19 shows the relative sensitivity of different types of data to error. Whilst the exact BER (bit error rate) which can be tolerated will depend on the application, digital audio is less tolerant of errors than digital video and more tolerant than computer data.
