Multi-screen display system

摘要

Provided is an image play/update control means (7), which: computes a phase difference between a synchronization adjustment signal (SAS) which is created from synchronization adjustment data (SAD) which is received from a distribution device (TA) via a data receiving means (6), and an image display control signal (HC) which is outputted to an image display means (8); varies the period of succeeding image display control signals (HC) in accordance with the phase difference, reducing the phase difference, and thereby adjusts image update timing among a plurality of display devices. It is possible to synchronize image updates with a plurality of display devices within a given allowable range.
