We have implemented a VNC (Virtual Network Computing) viewer into our digital TV sets. VNC has been widely used for PCs in order to enable us to view a screen of a remote PC connected through a network. Since most digital TVs in the market are equipped with a network interface and their embedded CPU becomes powerful enough to do some tasks in addition to its main jobs to control the TV operations, a VNC viewer can be implemented without adding or modifying the hardware. We have introduced a window system in order to allow users to change the size and the position of a VNC viewer screen freely within the whole TV screen.
