Abstract: The present invention provides screen displaying technology allowing improvement in operability and convenience for the user. A screen display apparatus receives a content, displays a plurality of tabs in a display screen, corresponds content information to any one of the plurality of tabs, and displays the content information corresponding to a displaying tab. In the case of corresponding content information to a non-displaying tab other than the displaying tab, it is determined whether or not a there is a non-corresponded, non-displaying tab to which other content information is not corresponded, and when the non-corresponded, non-displaying tab does not exist, the non-displaying tab selected based on a predetermined selection condition and the content information are corresponded.

Abstract: A system and method for compressing video graphics data are provided. The system and method include generating in a graphics pipeline, from video graphics data modeling objects, vertex data corresponding to the objects, rendering the video graphics data to produce a current frame of pixel data and a reference frame of pixel data, and, based upon the vertex data, defining a search area within the reference frame for calculating a motion vector for a block of pixel data within the current frame. The current frame then is compressed using the motion vector. The use of vertex data from the graphics pipeline to define the search area substantially reduces the amount of searching necessary to generate motion vectors and perform data compression.

Abstract: A manipulating device for an entertainment system is provided which overcomes the problems that might occur when an excessive force is applied thereto and permits smooth operation. A manipulating device 1 comprises an operating portion 10 and a stopper portion 40 that supports the operating portion 10. Leg portions 41 of the stopper portion 40 opens when depressive pressure is applied to the operating portion 10, and closes and restores the operating portion 10 to its initial position when the depressive pressure is released.
