Patent ID: 8704805

Claim:
A method for handling image data transfer in a display driver, comprising: receiving a stream of digital data including a plurality of successive data packets, and a timing signal that is distinct from the stream of digital data and is generated from a delay-locked loop or phase-locked loop circuit, the stream of digital data including synchronization information inserted in each boundary region between successive data packets, the synchronization information including a first field placed at the front of each of the data packets adjacent to a data field thereof and formed by one single bit that is assigned with a first binary value, and a second field placed at the tail of each of the data packets in which each bit is assigned with a same second binary value different from the first binary value, the first and second fields between each pair of successive data packets being adjacent to each other; in response to the timing signal, extracting a synchronizing signal from the synchronization information, wherein the step of extracting the synchronizing signal includes comparing the timing signal with a portion of the stream of digital data carrying the synchronization information, and generating the synchronizing signal upon detection in the synchronization information of a change of binary value from the second field to the first field adjacent thereto; and according to the synchronizing signal, generating a clock signal for retrieving encoded image data from one of the data packets in the stream of digital data.
