VIDEO SIGNAL SELECTOR APPARATUS AND CONTROL METHOD THEREOF

摘要

A video signal selector apparatus has an edition function for selecting or synthesizing an arbitrary video signal. Functions of an operation block are modularlized. Adjacent modules of panel modules (22A to 22D) which are operation modules are electrically connected by relay substrates (23, 24), so that a signal is transferred between the modules. Simultaneously with this, the panel modules (22A to 22D) are connected to the relay substrates (23, 24) by a connector. Thus, an operator can freely modify the layout of the panel modules (22B to 22D) of a division size based on 19−inch rack size.
