Abstract

Fine-structure pre-emphasis for video signal transmission exploits the three-dimensional redundancy of video signals. Companding is required in fine-structure pre-emphasis to realize SNR improvement. Fine-structure pre-emphasis is modeled as an open-loop predictive system. Analysis shows that a modulo limiter can be incorporated in the preemphasis filters to limit the peak amplitude of the pre-emphasized signal. The reduced dynamic range will alleviate stringent requirement on companding.
