Projector and projector control method
The present technology relates to a projector and a projector control method that make it possible to improve the security of the projector. The projector includes a storage section and a communication control section. The storage section stores a connection destination list indicative of equipment connectable to the projector. In a case where the projector is to be connected to another equipment through a network, the communication control section controls connection to the other equipment according to the connection destination list. The present technology is applicable, for example, to a projector or the like that is to be connected to another equipment through a network.
1. A projector, comprising:
a memory that stores a connection destination list indicative of equipment connectable to the projector; and
communication control circuitry configured to
when determining that a time for acquiring display data from a first device over a network has occurred, determine, by accessing the stored connection destination list, whether or not the projector is permitted to connect to the first device, and
only in response to determining that the projector is permitted to connect to the first device, access the first device to acquire the display data.
2. The projector according to claim 1 , wherein, according to the connection destination list, the communication control circuitry is further configured to control connection of a second device attempting to access the projector.
3. The projector according to claim 1 , wherein each item in the connection destination list is expressed by an URL or an IP address, each of which indicates a location of equipment.
4. The projector according to claim 1 , further comprising:
registration circuitry configured to register the connection destination list in the memory.
5. The projector according to claim 1 , further comprising:
display control circuitry configured to acquire the display data to perform display control of an image.
6. A projector control method of controlling a projector, the method comprising:
storing a connection destination list indicative of equipment connectable to the projector;
when determining that a time for acquiring display data from a first device over a network has occurred, determining, by accessing the stored connection destination list, whether or not the projector is permitted to connect to the first device; and
only in response to determining that the projector is permitted to connect to the first device, accessing the first device to acquire the display data.
7. The projector of claim 1 , wherein the communication control circuitry is further configured to extract, from the acquired display data, equipment control information, and transmit a command to a second device to control the second device, based on the extracted equipment control information, and
wherein the communication control circuitry is further configured to determine, by accessing the stored connection destination list, whether or not the projector is permitted to connect to the second device, prior to transmitting the command to the second device to control the second device.
