Signal processing device, signal processing method, computer program, and image transmission system

An image signal receiving method, the method comprising:

• receiving image control information;
• respectively receiving, by a plurality of image receivers, image signals transmitted from at least one display processor according to a multicast transmission, each image signal corresponding to at least a portion of at least one display image;
• and
• respectively processing the image signals according to image control information to produce the at least one display image.

A signal processing device comprising:

• a control information acquiring unit configured to acquire image control information regarding control of an image;
• an image receiver configured to selectively receive one or more images transmitted using multicast based on the image control information;
• one or more image processing units configured to perform an image process on an image received by the image receiver based on the image control information;
• and
• an image sender configured to transmit an image subjected to the image process by the image processing unit based on the image control information, the image being transmitted using multicast.

A signal processing method comprising:

• acquiring image control information regarding control of an image;
• selectively receiving one or more images transmitted using multicast based on the image control information;
• performing an image process on the selectively received image based on the image control information;
• and
• transmitting the image subjected to the image process based on the image control information, the image being transmitted using multicast.

A computer program for causing a computer to execute:

• acquiring image control information regarding control of an image;
• selectively receiving one or more images transmitted using multicast based on the image control information;
• performing an image process on the selectively received image based on the image control information;
• and
• transmitting the image subjected to the image process based on the image control information, the image being transmitted using multicast.

An image processing system comprising:

• an image control device;
• one or more image output devices;
• one or more signal processing devices;
• one or more image receiving devices;
• and
• one or more image display devices,
• wherein the signal processing device includes
• a control information acquiring unit configured to acquire image control information regarding control of an image from the image control device,
• an image receiver configured to selectively receive one or more images transmitted using multicast from the one or more image output devices based on the image control information,
• one or more image processing units configured to perform an image process on an image received by the image receiver based on the image control information, the image process being for displaying the image on the one or more image display devices, and
• an image sender configured to transmit an image subjected to the image process by the image processing unit based on the image control information to cause the image to be received by the one or more image receiving devices, the image being transmitted using multicast.
