System and method for controlling shutters of a shutter glass viewing device

摘要

There are provided a transmitter, a display, a shutter eyeglass device, a transmission/reception system, a display system and a transmission/reception method allowed to achieve highly reliable communication between a transmission side and a reception side. The transmitter includes: a transmission section holding plural kinds of commands each represented by a plurality of bits and repeatedly transmitting a command set, the command set being configured of one or more kinds of commands which are selected from the plural kinds of commands and combined in predetermined order, in which a bit pattern representing a whole of the command set is the same as a bit pattern held in a receiver.

1. A display apparatus, comprising:
a command generator to generate shutter control commands to control a shutter glass device for viewing a content displayed on the display apparatus, the shutter glass device including a first shutter and a second shutter, wherein the shutter control commands include a command to simultaneously perform operations of open the first shutter and close the second shutter, wherein the display apparatus selectively transmits the command to simultaneously perform operations of open the first shutter and close the second shutter and does not transmit the command to simultaneously perform operations of open the first shutter and close the second shutter based on a duty ratio representing a ratio of respective open periods for the first shutter and second shutter, such that (i) the command to simultaneously perform operations of open the first shutter and close the second shutter is transmitted when the duty ratio is equal to a first value and (ii) the command to simultaneously perform operations of open the first shutter and close the second shutter is not transmitted when the duty ratio is equal to a second value, and wherein the display apparatus transmits the command to simultaneously perform operations of open the first shutter and close the second shutter only when a duty cycle of a synchronization control signal for the content is within a predetermined range having a lower boundary and an upper boundary, wherein the lower boundary and the upper boundary are different from each other, the predetermined range excluding a range between 0% and the lower boundary, and excluding a range between the upper boundary and 100%.
