<p><P>PROBLEM TO BE SOLVED: To provide an intercom system for enhancing the visibility of an image displayed on a monitor by ensuring excellent image quality without causing deformation in the image when correction of a detected code error is disabled in the case that the code error such as a noise takes place in a video signal coded and transmitted from a slave unit to a master unit via a transmission path. <P>SOLUTION: In the case that the code error such as noise is produced in the video signal coded and transmitted from the first slave unit (slave unit) 1a to the first master unit (master unit) 2a via the transmission path L, the display of the image outputted to the monitor 204 when the correction of the detected code error is disabled is switched to re-display of a video signal of a frame having been outputted to the monitor before the detection of the code error or display of a prescribed video image. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
