Abstract
A projector system includes a plurality of projectors, in which a projector A and a projector B, and the projector B and a projector C are connected by a daisy chain method via each of cables, and the projector A outputs control information which controls the projector B or the projector C to the projector B via a data line of the cable along with image data and the projector B extracts and processes the control information input from the data line of the cable.
Claims12
A projection system comprising:
- a control device;
- and
- a plurality of projectors, wherein
- the control device and the projectors, and each of the projectors, are connected by a daisy chain method via a plurality of cables forming a daisy chain,
- each cable has a data line which transmits image data,
- the control device outputs control information which controls the projectors to the projectors via each data line along with the image data,
- the projectors extract and process the control information input from each data line of each cable,
- the projector located at an end of the daisy chain furthest from the control device among the plurality of projectors is connected to the control device by a loop cable,
- the loop cable has a data line which transmits image data,
- the projector located at the end of the daisy chain outputs the control information to the data line of the loop cable, and
- the control device extracts and processes the control information input from the data line of the loop cable.
A control device constituting a projection system along with a plurality of projectors, wherein
- the control device and the projectors, and each of the projectors, are connected by a daisy chain method via a plurality of cables forming a daisy chain, each cable having a data line which transmits image data,
- the control device comprising:
- a transmitter which outputs control information which controls the projectors to the projectors via each data line along with the image data,
- the projectors extract and process the control information input from each data line of each cable,
- the projector located at an end of the daisy chain furthest from the control device among the plurality of projectors is connected to the control device by a loop cable,
- the loop cable has a data line which transmits image data,
- the projector located at the end of the daisy chain outputs the control information to the data line of the loop cable, and
- the control device extracts and processes the control information input from the data line of the loop cable.
A control method of a projection system comprising a control device and a plurality of projectors, wherein
- the control device and the projectors, and each of the projectors, are connected by a daisy chain method via a plurality of cables forming a daisy chain,
- each cable has a data line which transmits image data,
- the control device outputs control information which controls the projectors to the projectors via each data line along with the image data,
- the projectors extract and process the control information input from each data line of each cable,
- the projector located at an end of the daisy chain furthest from the control device among the plurality of projectors is connected to the control device by a loop cable,
- the loop cable has a data line which transmits image data,
- the projector located at the end of the daisy chain outputs the control information to the data line of the loop cable, and
- the control device extracts and processes the control information input from the data line of the loop cable.
