Patent ID: 7602422

Claim:
A method for signaling a start and end of frame and line data for a serial interface having a maximum of two signal lines, comprising method operations of: receiving image data over a first line; receiving a clock signal associated with the data over a second line; while receiving the image data, the method includes, counting a number of clock cycles; comparing the number of clock cycles to a value representing a number of pixels defining a horizontal line within the frame data; continuing the counting and the comparing until the number of clock cycles matches the value; when the number of clock cycles matches the value, the method includes, identifying the end of the line data; resetting a count representing the number of clock cycles; counting the number of clock cycles; comparing the number of clock cycles to a value representing a non-display period between horizontal lines within the frame data; and when the number of clock cycles matches the value representing the non-display period, the method includes, repeating the above method operations for successive line data.
