Abstract

A display (200) includes: a wireless communication control section (215) which receives an image signal transmitted from an STB (100); and a reservation time monitoring section (204) which, in response to an instruction from a user to change a state of the display (200) to a standby state, determines, in accordance with a time remaining before a reserved viewing is started, whether or not to stop supplying electric power to the wireless communication control section (215).

Claims

1-12. -12. (canceled)

13. A display device for displaying an image, comprising:

a receiving section which receives an image signal transmitted from a transmission device and indicative of the image, the transmission device externally receiving the image signal and then transmitting the image signal to the receiving section,

together with the display device, the transmission device constituting a display system, and

the display device including determining means for, in response to an instruction from a user to change a state of the display device to a standby state, determining, in accordance with a time remaining before a reserved viewing is started, whether or not to stop supplying electric power to the receiving section.

14. The display device as set forth in claim 13, wherein, after stopping supplying electric power to the receiving section, the determining means determines, in accordance with the time remaining before the reserved viewing is started, whether or not to start supplying electric power to the receiving section.

15. The display device as set forth in claim 13, further comprising:

standby state setting means for, in response to the instruction from the user to change the state of the display device to the standby state, setting whether or not to change the state of the display device to the standby state,

when the state of the display device is set, by the standby state setting means, to be changed to the standby state, the determining means determining whether or not to stop supplying electric power to the receiving section.

16. The display device as set forth in claim 15, further comprising:

reservation presence/absence confirming means for confirming whether or not the reserved viewing is present,

in a case where it has been confirmed by the reservation presence/absence confirming means that the reserved viewing is present, the standby state setting means setting the state of the display device to be changed to the standby state in which the display device can start automatically at a reservation time.

19. The display device as set forth in claim 13, wherein:

the receiving section receives, from the transmission device, information indicating that a reserved viewing start time has come,

said display device further comprising;

activating means for activating the display device when the receiving section receives the information.

20. A display system comprising:

a transmission device which transmits an image signal; and

a display device recited in claim 13.

22. A non-transitory computer-readable storage medium storing therein a program for causing a computer to operate as a display device recited in claim 13, the program causing the computer to function as each means of the display device.

17. A display device for displaying an image, comprising:

a receiving section which receives an image signal transmitted from a transmission device and indicative of the image; and

electric power supply means for, when a state of the display device is a standby state and a time remaining before a reserved viewing is started falls below a predetermined threshold, starting supplying electric power to the receiving section.

18. The display device as set forth in claim 17, further comprising:

synchronizing means for temporarily activating the display device in a background at regular time intervals, and synchronizing with the transmission device in terms of a time at which the reserved viewing is started,

the synchronizing means changing the state of the display device to the standby state after synchronizing with the transmission device in terms of the time at which the reserved viewing is started.

21. A method for controlling a display device for displaying an image, the display device including a receiving section which receives an image signal transmitted from a transmission device and indicative of the image,

said method comprising the step of:

in response to an instruction from a user to change a state of the display device to a standby state, determining, in accordance with a time remaining before a reserved viewing is started, whether or not to stop supplying electric power to the receiving section.
