Interface and method for image data transmission

Abstract

An interface and a method for image data transmission that is used for data transmission through a plurality of data lines is described, the correctness of the transmitted data being checked by reference to control data. The checking capability is achieved in that at least one item of control data is transmitted through each data line.

1 . An interface for image data transmission, comprising:
 at least two data lines; and   one clock pulse line for transmitting a clock pulse;   wherein pixel data and control data are transmitted through the at least two data lines for producing an image from the pixel data, at least one item of control data being transmitted on each of the at least two data lines, whereby a correctness of pixel data transmission is checked by reference to control data transmission.   
   
   
       2 . The interface of claim  12 , further comprising:
 a counter for counting clock pulses since a last change in one item of control data; and   a comparison unit for comparing a counter value with a stored value;   wherein an error condition is determined when the counter value exceeds the stored value by a defined degree.
