Introduction

The characteristics to be adopted for receiving equipment for broadcasting-satellite systems offer a wide range of choice. These characteristics influence the size, mass and complexity of the satellite required to provide a given quality of service because of the compromise that must be made between receiver sensitivity and the power radiated by the satellite. They themselves are affected by the broadcasting standards selected. In particular, the characteristics of the receiving equipment will depend on whether it is required to receive only television signals (with only one or with more than one, accompanying sound signal), or only sound signals, or both. The present Report gives information about the most important of these characteristics on the basis of the results presented in the documents listed in the references of this Report. Many of the contributions received relate to equipment operating in the 12 GHz frequency band.

It appears that signals broadcast from satellites could be received, not only by equipments of new design, but in some cases by existing receivers fitted with adaptive devices.

As satellite broadcasting is capable of delivering a high quality TV signal to the general public, comparable to that of the studio, it seems practicable to set a higher quality target for receivers.

A distinction should be made between installations intended for community reception and for individual reception.
