This prototype television bandwidth compression system, based on Cherry et al.’s experimental design, supports black‑and‑white and half‑tone images under realistic noise conditions. The system uses adjustable parameters to achieve optimal run‑length encoding, leveraging run‑length quantization and modest buffer stores, while a low‑cost receiver employs a quantized‑variable‑velocity principle, making it simple and inexpensive for widespread deployment.

The transmitter/receiver system for bandwidth or data-rate compression of television signals, described herein, is a prototype model of the experimental system of Cherry et al. [1]. The system is suitable for both black-and-white or half-tone pictures, in realistic noise conditions. The system parameters my be adjusted so that an optimum run-length encoding may be found; the great advantages of run-length quantizing are shown, especially with regard to practical instrumentation, leading to the use of buffer stores of modest capacity. One particular cheap form of receiver operates on a quantized-variable-velocity principle and, being much more simple and cheap than the transmitter, is suitable for use in situations requiring many receivers.
