Abstract: The present invention relates to a multi-vision having a daisy chain type, capable of automatically setting an ID of each multi-vision set in a multi-vision where a plurality of sets are connected to each other in a daisy chain form, and an ID allocating method thereof. The multi-vision having a daisy chain type includes: a plurality of multi-vision sets; a first off switch provided at an IR communication line output port of each of the multi-vision sets, and configured to block an IR signal applied to each multi-vision set; series communication lines connected to the plurality of multi-vision sets in a bypass form; a second off switch provided at an output port of the series communication line of each multi-vision set, and configured to block an ID value which is to be bypassed to a next multi-vision set through the series communication line; and a controller configured to set an ID of a reference multi-vision set by blocking the first and second off switches, and configured to transmit an ID increased value to a next multi-vision set by releasing the blocked output state of the second off switch from the reference multi-vision set.
