A method is described for FEC decoding a signal which has become affected by transmission errors, the original signal being transmitted together with parity data. An integrated circuit having high performance CMOS devices with low parasitic junction capacitance may be made by forming a gate structure over a substrate; forming pocket implant regions and sourcedrain extensions in the substrate; forming spacers along sides of the gate structure; performing a low dosage sourcedrain implant; and performing a high dosage sourcedrain implant. By merging the textures to generate a single output image before causing a display device to display the image, the overlay and the video image may present an augmented reality interface that remains in synch between the overlay and the underlying image.
