Abstract: A 3-D wireless game controller includes a housing having an upper surface, a lower surface, and a grip for holding by the user's hand; a push control element mounted to the upper surface of the housing; a rotation control element rotatably mounted to the lower surface of the housing and located corresponding to the user's forefinger pad while the user holds the grip; a gravity sensor mounted to the housing; a power unit mounted in the housing; and a wireless communication module electrically connected with the push control element, the rotation control element, and the gravity sensor. In light of this, the 3-D wireless game controller allows the user's finger pad to roll the rotation control element for additional control functions.

Abstract: The present invention provides a digital media mixer including a plurality of analog-to-digital converters for transforming analog audio/video signals to digital audio/video signals, a plurality of encoders for encoding the digital audio/video signals, a multiplexer for mixing the encoded digital audio/video signals using an MPEG-2 TS format, and a network interface for transferring the mixed digital audio/video signals by a broadcast technology or a multicast technology.
