Digital data transmission apparatus and digital data transmission method

摘要

The present invention has a comparing unit that compares each of image signals in a first clock period with a corresponding one of the image signals in a second clock period subsequent to the first clock period, and a cancelling unit that causes each of the image signals in the second clock period to be cancelled in the case where a comparison result from the comparing unit indicates that each of the image signals in the first clock period agrees with the corresponding one of the image signals in the second clock period.

主权项

1. A data transmission apparatus that serially transmits a plurality of image signals to an image display device by using digital data which has said image signals allocated in a single clock period, comprising:
a comparing unit that compares each of said image signals in a first clock period with a corresponding one of said image signals in a second clock period subsequent to said first clock period; and a cancelling unit that causes each of said image signals in said second clock period to be cancelled in the case where a comparison result from said comparing unit indicates that each of said image signals in said first clock period agrees with said corresponding one of said image signals in said second clock period, wherein said cancelling unit causes each of said image signals in said second clock period to be canceled by eliminating a difference between a High state and a Low state of said digital data corresponding to said image signals allocated to continuous time domains of said second clock period.
