Abstract
A sub image display control system is composed of two sub image display control portions that are a display region control portion and a display timing control portion and a display output portion. A sub image data packet is composed of three types of data that are a sub image header, sub image display data, and sub image control data. In this structure, display spatial loss and display temporal loss can be remarkably reduced and sub images with wide applicability can be accomplished.
