A network management device includes a processor configured to execute a ranking process, a throughput-increasing process, an overall video signal generation process, and an overall video signal supplying process. In the ranking process, the processor ranks multiple moving images taken by cameras of wireless communication terminals simultaneously capturing an event performed in an event venue to select multiple moving images ranked higher. In the throughput-increasing process, the processor increases uplink throughput for the multiple wireless communication terminals corresponding to the multiple moving images ranked higher selected in the ranking process. In the overall video signal generation process, the processor generates an overall video signal including multiple video signals corresponding to the multiple wireless communication terminals for which the uplink throughput is increased in the throughput-increasing process. In the overall video signal supplying process, the processor supplies the overall video signal generated in the overall video signal generation process to at least one reproduction device in which moving images are reproduced. The overall video signal is in a format that enables the reproduction device to simultaneously reproduce the multiple moving images corresponding to the multiple video signals in the overall video signal.

Content data representing content that includes at least one or more components is acquired. Projection area data representing a projection area is acquired. A deteriorated part, which is a part where a projection condition is deteriorated in the projection area, is identified based on the projection area data. A priority of the component included in the content is identified. Display deterioration of the content, which is caused by the deteriorated part, is suppressed based on a position of the identified deteriorated part in the projection area, the content data displayed on the projection area, a threshold according to the identified priority, and a degree of deterioration indicative of a level of deterioration of the component.

Content projection control device, information processing method, and program

An estimator () estimates whether an object is on the line of sight of the user. When a first object is estimated as being on the line of sight of the user continuously for a first threshold time, set for the user, or longer, a displayer () displays a second object in the field of view of the user. The second object expresses information about the first object. When the second object is estimated as not being on the line of sight of the user continuously for a second threshold time, set for the user, or longer, a remover () removes the second object from the field of view of the user. A corrector () corrects the first threshold time according to the length of viewing time that the second object is estimated as being on the line of sight of the user. Here, the first threshold time is set for the user.
