Abstract:
1. A communication apparatus configured to connect to a display terminal via a wireless access apparatus allowed to freely change a spatial multiplexing number of a spatial multiplexing transmission path, comprising: a first generation unit which generates image data in accordance with an event occurring due to a change in an operating state of an application program; a difference detecting unit which detects a difference between a plurality of consecutive image data generated by said first generation unit; a second generation unit which generates send data to be sent to the display terminal by compressing the difference; a message generating unit which generates a message to change the spatial multiplexing number to either one or a plural number according to the change in the operating state of the application program or the difference; a sending unit which sends the send data to the display terminal and sends the message to the wireless access apparatus prior to sending the send data; a storage unit which stores spatial multiplexing number switching information on the spatial multiplexing transmission path in association with information on the event occurring due to the change in the operating state of the application program; and an event acquiring unit which acquires the information on the event occurring due to the change in the operating state of the application program, wherein said message generating unit reads the spatial multiplexing number switching information associated with the information on the event acquired by said event acquiring unit from said storage unit and generates the message to change the spatial multiplexing number.
