MULTISCREEN DISPLAY APPARATUS

摘要

A calculating unit of a master apparatus that comes first in a transmission sequence calculates coordinates of a plurality of video display apparatuses on a multiscreen on the basis of arrangement information and the transmission sequence. The calculating unit an identification number on the basis of an identification setting rule. A setting unit performs a processing for setting the identification number of each of the video display apparatuses with the calculated coordinates to the video display apparatus concerned.

主权项

1. A multiscreen display apparatus, comprising a plurality of video display apparatuses arranged in matrix and daisy-chain connected through a communication cable such that screens of said plurality of video display apparatuses form a multiscreen having a rectangular shape, wherein
for said plurality of video display apparatuses, a transmission sequence in which information is transmitted between said plurality of video display apparatuses through said daisy chain connection is defined, and a reference video display apparatus that comes first in said transmission sequence from among said plurality of video display apparatuses includes processing circuitry
to calculate coordinates of said plurality of video display apparatuses on said multiscreen on the basis of said transmission sequence and arrangement information for specifying an arrangement configuration of said plurality of video display apparatuses, andto calculate an identification number for identifying each of said plurality of video display apparatuses on the basis of a predetermined rule for setting said identification number to each of said plurality of video display apparatuses; andto perform a processing for setting said identification number of each of said plurality of video display apparatuses with the calculated coordinates to said video display apparatus concerned.
