The present invention provides a device and a method for displaying appropriately on the display area for each processing unit such as an application according to the applied equipment. The CPUprocesses display area acquisition requests from a plurality of processing units R-Rn according to a display management program. The display management program decides whether use of the display area is allowed to each processing unit, considering the relationship of the plurality of display areas requested from each processing unit R-Rn. Each processing unit R-Rn executes display processing for the display area for which use is allowed. In this way, whether use is allowed is notified from the display management program to each processing unit R-Rn after each processing unit R-Rn sends the display area acquisition request. As a consequence, display in a plurality of areas by each processing unit R-Rn can be controlled appropriately.

Display control device and method

To provide a device capable of determining a delivery destination of an event automatically without requiring choosing operation of an operator. An event entered through an event input meansis given to a delivery destination determining meanswhich in turn determines to which of applications AP, AP, . . . , APn the given event is to be delivered according to the contents of the event and according to delivery destination determining information stored in a delivery destination determining information storing section, and delivers accordingly. Therefore, the event is delivered to an appropriate application even if the operator does not choose an addressed application.

Event control device and digital broadcasting system

A display control device for controlling a display of a display device responding to display processing from a plurality of processing units. A display controlling program controls the display device in response to at least one processing unit. The display controlling program receives a request from one processing unit to acquire one of predefined display areas, and determines whether to provide an authorization to acquire one of a plurality of predefined display areas in response to an acquisition request from the one processing unit. When a plurality of requests to acquire the same one of predefined display areas from a plurality of processing units are received, authorization is provided to a single processing unit that made one of the requests to acquire the same one of predefined display areas. The display device is instructed by a processor, based on the display controlling program. A memory, connected to the processor, stores the display controlling program. When an acquisition request for the same one of predefined display areas is received, the processor instructs the display device based on the display controlling program.

The present invention provides a device and a method for displaying appropriately on the display area for each processing unit such as an application according to the applied equipment. The CPUprocesses display area acquisition requests from a plurality of processing units R1-Rn according to a display management program. The display management program decides whether use of the display area is allowed to each processing unit, considering the relationship of the plurality of display areas requested from each processing unit R1-Rn. Each processing unit R-Rn executes display processing for the display area for which use is allowed. In this way, whether use is allowed is notified from the display management program to each processing unit R1-Rn after each processing unit R1-Rn sends the display area acquisition request. As a consequence, display in a plurality of areas by each processing unit R1-Rn can be controlled appropriately.
