Claim:
1. A method of palette mode coding using palette prediction for a picture, wherein the palette prediction includes a copy-above mode for predicting one or more first pixels based on one or more second pixels located above said one or more first pixels correspondingly, the method comprising: receiving input data associated with a current block; determining a current coding mode for one or more current pixels; if the current coding mode is the copy-above mode, identifying one or more above pixels located above said one or more current pixels correspondingly for said one or more current pixels to copy from said one or more above pixels; and if said one or more above pixels include one or more current Escape pixels, signaling one or more Escape values for said one or more current Escape pixels or terminating a copy-above run at a first above pixel being one Escape pixel.
