Rediffusion - English Definition & Meaning

Definition

Rediffusion is the distribution of radio or television signals by cable to areas with poor reception. Think of it as an early form of cable TV and radio. 📡 It re-transmits signals received from a central antenna to individual homes. This was particularly useful in areas blocked by hills or tall buildings. Rediffusion systems provided better signal quality and a wider range of channels. Though largely replaced by modern cable and satellite services, it played a crucial role in early broadcasting.
