Abstract

A television system (100) comprises a sending station (70), a composing station (80) and a receiving station (90). The sending station (70) comprises a sequence of cameras (1, 2, 3,..., N) arranged so that the fields of view merge contiguously to form an aggregate field of view. The composing station (80) includes circuitry which enables a local viewer at the receiving station (90) to select an arbitrary and continuously variable subsection of the aggregate field of view for display on a local monitor (200).
